FAIL SAFE UNIT
1. INTRODUCTION
This specification sets forth the minimum requirements for a shelf-mountable,
sixteen channel, solid-state Malfunction Management Unit (MMU). The MMU shall
meet, as a minimum, all applicable sections of the NEMA Standards Publication No.
TS2-1998. Where differences occur, this specification shall govern.
2. MONITORING FUNCTIONS
The following monitoring functions shall be provided in addition to those required
by the NEMA Standard Section 4.
2.1 DUAL INDICATION MONITOR
Dual Indication monitoring shall detect simultaneous input combinations of
active Green (Walk), Yellow, or Red (Don’t Walk) field signal inputs on the same
channel. In Type 12 mode this monitoring function detects simultaneous input
combinations of active Green and Yellow, Green and Red, Yellow and Red, Walk
and Yellow, or Walk and Red field signal inputs on the same channel.
2.1.1 DUAL INDICATION MONITORING
Sixteen switches labeled FIELD CHECK/DUAL ENABLES shall be provided on
the MMU front panel to enable Dual Indication Monitoring on a per channel
basis. The Dual Indication Monitor function shall provide two modes of
operation, Dual Indication Fault and GY-Dual Indication Fault.
When voltages on two inputs of a vehicle channel are sensed as active for
more than 450 msec, the MMU shall enter the fault mode, transfer the
OUTPUT relay contacts to the Fault position, and illuminate the DUAL
INDICATION indicator. The MMU shall remain in the fault mode until the unit
is reset by the RESET button or the EXTERNAL RESET input. When voltages
on two inputs of a vehicle channel are sensed as active for less than 200
msec, the MMU shall not transfer the OUTPUT relay contacts to the Fault
position.
When operating in the Type 16 mode with Port 1 communications enabled,
Bit #68 (Spare Bit #2) of the Type #129 response frame shall be set to
indicate a Dual Indication fault has been detected.
Dual Indication Monitoring shall be disabled when the RED ENABLE input is
not active.
2.1.2 GY-DUAL INDICATION MONITOR
GY-Dual Indication monitoring shall detect simultaneous inputs of active
Green and Yellow field signal inputs on the same channel. It will be used to
monitor channels which have an unused Red field signal input tied to AC
LINE such as a five section signal head.
GY-Dual Indication Monitoring shall be enabled by a front panel option
switch. When the GY-Dual Indication Monitoring option is enabled, all
channels which have the front panel FIELD CHECK/DUAL ENABLE switches
OFF shall be individually monitored for simultaneous active Green and
Yellow field signal inputs. All channels which have the front panel FIELD
SP 11
CHECK/DUAL ENABLE switches ON (i.e. enabled for Dual Indication
Monitoring) shall function as described above in Dual Indication Monitoring.
2.2 FIELD CHECK MONITORING
Sixteen switches labeled FIELD CHECK/DUAL ENABLES shall be provided on the
MMU front panel to enable Field Check Monitoring on a per channel basis. The
Field Check Monitor function shall provide two modes of operation, Field Check
Fault and Field Check Status.
Field Check Monitoring shall be disabled when the RED ENABLE input is not
active. The Field Check Monitoring function shall be disabled in the Type 12
mode.
2.2.1 FIELD CHECK MONITOR
In the Field Check Fault mode, when the field signal input states sensed as
active or inactive by the MMU do not correspond with the data provided by
the Controller Unit in the Type #0 message for 10 consecutive messages, the
MMU shall enter the fault mode, transfer the OUTPUT relay contacts to the
Fault position, and illuminate the FIELD CHECK FAIL indicator. The Channel
Status Display shall indicate the channels on which the Field Check fault was
detected. Bit #67 (Spare Bit #1) of the Type #129 response frame shall be set
to indicate a Field Check fault has been detected. The MMU shall remain in
the fault mode until the unit is reset by the RESET button or the EXTERNAL
RESET input.
2.2.2 FIELD CHECK STATUS
The Field Check Status mode shall work in combination with the other fault
monitoring functions of the MMU. When a Conflict, Red Fail, Clearance Fail,
or Dual Indication Fail triggers the MMU, the Channel Status Display and
Fault Status Display shall correspond to that detected fault. If Field Check
errors were detected while the fault was being timed, the inputs on which
the Field Check errors were detected shall double pulse at the same time as
the FIELD CHECK STATUS indicator. Bit #67 (Spare Bit #1) of the Type #129
response frame shall also be set to indicate Field Check errors have been
detected.
2.3 RECURRENT PULSE MONITORING
The Signal Monitor shall detect Conflict, Red Fail, and Dual Indication faults that
result from intermittent or flickering field signal inputs. These recurring pulses
shall result in a latching fault with the RECURRENT PULSE STATUS indicator
illuminated along with the resulting Conflict, Red Fail, or Dual Indication
indicator. An option switch shall be provided to disable the RP detect function
for testing purposes.
When operating in the Type 16 mode with Port 1 communications enabled, Bit
#69 (Spare Bit #3) of the Type #129 response frame shall be set to indicate a
Recurrent Pulse status has been detected.
2.4 EXTERNAL WATCHDOG MONITOR
The MMU shall provide the capability to monitor an optional external logic level
output from a Controller Unit or other external cabinet circuitry. If the MMU
does not receive a change in state on the EXTERNAL WATCHDOG input for 1500
SP 12
msec (_+100 msec), the MMU shall enter the fault mode, transfer the OUTPUT
relay contacts to the Fault position, and illuminate the CVM/WATCHDOG
indicator. The MMU shall remain in the fault mode until the unit is reset by the
RESET button or the EXTERNAL RESET input. An MMU Power Failure shall reset
the CVM/WATCHDOG fault state of the monitor. The EXTERNAL WATCHDOG
input shall be wired to connector MSB-S.
When operating in the Type 16 mode with Port 1 communications enabled, Bit
#70 (Spare Bit #4) of the Type #129 response frame shall be set to indicate an
External Watchdog fault has been detected.
2.5 WALK DISABLE OPTION
The MMU shall provide the capability to exclude the Walk inputs from the Red
Fail fault detection algorithm when operating in the Type 12 mode. When the

9-29.18(1) Induction Loop Detectors
Section 9-29.18(1) is replaced with:
(******)
4 Channel Rack Mount Detector Specifications:
The detector shall be a Reno A&E model C or a pre-approved equal meeting the following
specifications:
PHYSICAL
Weight: 6 oz. (170 gm.).
Size: 4.500 inches (11.43 cm.) high x 1.12 inches (2.84 cm.) wide x 6.875 inches (17.46 cm.)
long including connector (not including front handle).
Operating Temperature: -40°F to +180°F (-40°C to +82°C)
Circuit Board: Printed circuit boards are 0.062in. FR4 material with 2 oz. copper on both
sides and plated through holes. Circuit board and components are conformal
coated with polyurethane.
Connector: 2 x 22 pin edge card connector with 0.156-inch (0.396 cm.) contact centers. Key
slots located between B & C and M & N.
Loop Feeder Length: Up to 5000 feet (1500m.) maximum with proper feeder cable and
appropriate loops.
ELECTRICAL
Power: 10.8 to 30 VDC, 120 mA max.
Loop Inductance Range: 20 to 2500 microHenries with a Q factor of 5 or greater.
Loop Inputs: Transformer isolated. The minimum capacitance added by the detector is
0.068 microFarad.
SP 28
Lightning Protection: The detector shall be able to tolerate, without damage, a 10
microFarad capacitor charged to 2,000 volts being discharged directly into the loop
input terminals, or a 10 microFarad capacitor charged to 2,000 volts being
discharged between either loop terminal and earth ground.
Reset: Shall meet and/or exceed NEMA TS 1 and TS 2 detector specifications. Application of
a 30-millisecond low state (0 to 8 VDC) to pin C shall reset both channels. Each
detector channel shall be manually reset by pressing the CHAN button until the
desired channel is selected, then holding the CHAN button for 3 seconds, or by
changing the sensitivity or loop frequency of the channel.
Phase Green Inputs: Also known as Call Delay Overrides. Shall meet and/or exceed all NEMA
TS 1 and TS 2 requirements. Application of a Low state voltage (0 to 8 VDC) to pin
1(Ch. 1) and/or pin 2 (Ch. 2) shall cause the delay timer for the channel to abort the
delay timing function and also provide control for Phase Green Loop Compensation,
Max Presence Timing (End-of-Green), Extension timing, and Detector Disconnect, if
the features are programmed.
Fail-Safe Outputs: Per NEMA TS 2 - conducting state indicates detection output. Each
detector channel output shall default to a CALL state for any loop failure condition
or loss of power.
Channel Status Outputs: Per NEMA TS 2 - Each channel shall have an output to communicate
the status states of the channel as follows:
Normal operation Continuous Low or On State
Detector failure Continuous High or Off State
Open loop 50 millisecond On time, 50 millisecond Off time
Shorted loop 50 millisecond On time, 100 millisecond Off time
Excessive inductance change (±25%) 50 millisecond On time, 150 millisecond Off time
Solid State Output Ratings: Shall be optically coupled field effect transistors. 30 VDC max.
drain to source. 50 mA. max. current. The output transistor shall be protected with
a 33-volt zener diode connected between the drain and source.
OPERATIONAL
Display: Shall be LCD and back lighted whenever any push button is pressed. The back
lighting shall extinguish 15 minutes after the last actuation of any push button.
Detect Indicators: Each channel shall have an super high intensity red light emitting diode
(LED) to indicate a CALL output, Delay Timing, Extension Timing, Pending state, or
failed loop.
Response Time: Shall Meet or exceed NEMA TS 1 and TS 2 response time specifications.
Self-Tuning: The detector shall automatically tune and be operational within 2 seconds after
application of power or after being reset.
Environmental & Tracking: The detector shall be fully self-compensating for environmental
changes and loop drift over the full temperature range and the entire loop
inductance range.
Grounded Loop Operation: The loop isolation transformer shall allow operation with poor
quality loops (which may include one short to ground at a single point).
Loop (Fail) Monitor: If the total inductance of the channel’s loop input network goes out of
the range specified for the detector, or rapidly changes by more than ±25%, the
channel shall immediately enter the Fail-Safe mode and display “LOOP FAIL” on the
LCD. The type of loop failure shall also be displayed as “L lo” (for -25% change or
shorted loop conditions) or “L hi” (for +25% change or open loop conditions). This
will continue as long as the loop fault exists. The Fail-Safe mode shall generate a
continuous call in Presence Mode or in Pulse Mode. At the time of a loop failure,
the channel’s LED shall begin repeating a burst of three flashes each one second.
The LED shall continue these bursts until the channel is manually reset or power is
removed. If the loop “self heals”, the LOOP FAIL message on the LCD shall extinguish
and the channel will resume operation in a normal manner; except the LED shall
continue the bursts thus providing an alert that a Loop Fail condition occurred. Each
loop failure for the channel shall be counted and accumulated into the Loop Fail
Memory. The total number of loop failures written into the Loop Fail Memory (since
the last power interruption or manual reset) can be viewed by stepping through the
channel’s functions in Program Mode to the “LOOP FAIL” message.
SP 29
LOOP FREQUENCY
There shall be eight (8) selectable loop frequency settings per channel (normally in the range
of 20 to 100 kilohertz). The actual loop operating frequency shall be digitally displayed on
the LCD.
SENSITIVITY
There shall be nine (9) selectable sensitivity levels per channel, plus Continuous-Call and
Channel-Off. The sensitivity levels are to be designed so that a one level increase actually
doubles the sensitivity and a one level decrease halves the sensitivity. A bar graph shall be
displayed on the LCD to make it easy to quickly set the sensitivity to the ideal level for any
loop/lead-in network situation.
Continuous-Call: When set to the Continuous-Call state, the channel output shall be in the
continuously call state regardless of the presence or absence of vehicles over the
loop. The loop oscillator shall be disabled when in the “Continuous-Call State”. This
state shall be indicated by CALL flashing on the LCD. This option shall be selected
from the Sensitivity menu in Program Mode.
Channel-Off: When set to the Channel-Off state, the channel output shall be continuously
in the No-Call state regardless of the presence or absence of vehicles over the loop.
The loop oscillator shall be disabled when in the “Channel-Off State”. This state shall
be indicated by OFF flashing on the LCD. This option shall be selected from the
Sensitivity menu in Program Mode.
CALL DELAY
Each channel’s Call Delay shall be adjustable from 0 to 255 seconds in 1-second steps. Call
Delay time shall start counting down when a vehicle enters the loop detection zone. The
remaining Call Delay time shall be continuously displayed on the LCD. Whenever a Phase
Green Input (call delay override) signal (pins 1 or 2) is active (low state), the Call Delay
function for that channel shall be aborted and the Call Delay time forced to zero.
CALL EXTENSION
Each channel’s Call Extension shall be adjustable from 0 to 25.5 seconds in 0.1-second steps.
Extension time shall start counting down when the last vehicle clears the loop detection
zone. The remaining Extension time shall be continuously displayed on the LCD. Any vehicle
entering the loop detection zone during the Extension time period shall cause the channel
to return to the Detect state, and later, when the last vehicle clears the loop detection zone,
the full Extension time shall start counting down again.
PRESENCE/PULSE
One of two mutually exclusive modes of operation for each channel shall be available.
Presence or Pulse mode shall be toggled by momentarily pressing either the up or down
button.
Presence Mode: Will provide a Call hold time of at least 4 minutes (regardless of vehicle size)
and typically 1 to 3 hours for an automobile or truck.
Pulse Mode: An output Pulse of 125±10 milliseconds duration shall be generated for each
vehicle entering the loop detection zone. Each detected vehicle shall be instantly
tuned out if it remains in the loop detection zone longer than 2 seconds. After each
vehicle leaves the loop detection zone, the channel shall resume full sensitivity
within 0.5 seconds.
MAX PRESENCE TIMER
Each channel’s Max Presence timer shall be adjustable from 1 to 999 seconds in 1-second
steps, plus OFF. The Max Presence function is used to limit presence time, by automatically
resetting a channel. If this function is enabled (on), the Max Presence timer begins counting
down when a Call is initiated and the remaining time is continuously displayed on the LCD.
If the loop becomes vacant before the Max Presence timer reaches zero, the Call is dropped
and no automatic reset occurs. If the End-Of-Green (EOG) function is not enabled (off) and
the Call is still present when the Max Presence timer reaches zero, the channel then is
automatically reset. If the EOG function is enabled (on) and the Call is still present when the
Max Presence timer reaches zero, the channel enters a “Wait” state. The Wait state
continues until either the loop becomes vacant or the Phase Green Input signal for the
channel (pin 1 or 2) transitions from green to not green with the Call still present. If the loop
SP 30
becomes vacant first, the Call is dropped and no automatic reset occurs. If the Phase Green
Input for the channel transitions from green to not green while the channel is in a Wait state,
the channel is automatically reset. The signals on pins 1 and 2 are also called Call Delay
Overrides.
END-OF-GREEN (EOG)
Each channel’s EOG setting can be toggled ON or OFF by momentarily pressing either the
up or down button. The EOG function is used to synchronize resetting of a channel with the
termination of the associated phase green. The EOG function is only available when the Max
Presence function is set between 1 and 999 seconds. It is not available when the Max
Presence function is OFF. When the EOG function is enabled (ON), the channel will
automatically be reset at the time the phase green input signal (pin 1 or 2) transitions from
the ON state to the OFF state, if the Max Presence Time has counted down to zero and is
resting in the wait state. The signals on pins 1 and 2 are also called Call Delay Overrides.
OPTION 1, LOOP INDUCTANCE DISPLAY
The detector’s Loop Inductance Display setting shall be toggled ON or OFF by momentarily
pressing either the up or down button. When this option is enabled (on), the LCD will display
the total loop inductance (actual loop inductance plus actual lead-in inductance) in
microHenries with an accuracy of ±3% for loop inductance values in the range of 20 to 2500
microHenries. NOTE: Enabling this option activates it for all channels. This option shall be
automatically disabled 15 minutes after activation or on loss of power.
OPTION 2, LOOP INDUCTANCE -DL/L DISPLAY
The detector’s Loop Inductance -DL/L Display setting shall be toggled ON or OFF by
momentarily pressing either the up or down button. When this option is enabled (on), the
LCD displays the percentage of inductance change (-DL/L value) during the Call state. To
facilitate the viewing of the maximum amount of change in the -DL/L value while traffic is in
motion over the detection zone, the detector shall hold the peak -DL/L value for a period of
2 seconds. NOTE: Enabling this option activates it for both channels. This option shall be
automatically disabled 15 minutes after activation or on loss of power.
OPTION 3, CALL EXTENSION CONTROL
Each channel’s Call Extension Control setting shall be toggled ON or OFF by momentarily
pressing either the up or down button. When this option is enabled (on), the channel will
extend calls for the programmed extension time only when the Phase Green Input signal
(pin 1 or 2) is active for the channel. When this option is off, the channel shall extend ALL
calls for the programmed extension time. The signals on pins 1 and 2 are also called Call
Delay Overrides.
OPTION 4, NORMAL/FAST RESPONSE MODE
The detector’s Normal/Fast Response Mode setting shall be toggled ON or OFF by
momentarily pressing either the up or down button. When this option is enabled (on),
internal call filtering is disabled thus providing a faster response time. When this option is
off, normal call filtering is used. NOTE: Turning this option ON will make it active for both
channels.
OPTION 5, PHASE GREEN LOOP COMPENSATION
The detector’s Phase Green Loop Compensation setting shall be toggled ON or OFF by
momentarily pressing either the up or down button. When Option 5 is enabled (on), normal
loop compensation is used until the Phase Green Input signal (pin 1 or 2) becomes active.
Once the Phase Green Input signal is active, the detector shall desensitizes the loop.
Maximum desensitization shall not exceed 0.05% (-DL/L). This desensitization will “tune
out” small changes, such as adjacent lane pick up therefore minimizing the chance for max
timing an empty lane. When Option 5 is not enabled (off), normal loop compensation shall
be used.
OPTION 6, VEHICLE COUNTING DISPLAY (OPTIONAL OPTION)
When Option 6.0 is enabled (on) for a channel, the normal operating display for that channel
shall be replaced with the accumulated vehicle count. The unit shall be capable of
accumulating 65,535 vehicle counts before rolling over to 0. The display will show just the
SP 31
hundreds, tens, and ones digits until the accumulated count exceeds 999. At this point the
display will alternate between the ten thousands and thousands digits and the remaining
three digits for hundreds, tens, and ones. The accumulated vehicle count is cleared by loss
of power or can be manually cleared using Option 6.1.
Option 6.1 shall be used to reset the accumulated vehicle count for the selected
channel. When Option 6.1 is changed from the off state to the on state, the accumulated
vehicle count for the selected channel shall be reset to zero. Option 6.1 shall always be in
the off state when first viewed.
OPTION 7, VEHICLE COUNTING LOOP CONFIGURATION (OPTIONAL OPTION)
The detector's Vehicle Counting Loop Configuration setting shall be set from 01 to 04 for
each channel. This setting should indicate the number of loops installed in a single lane. 01
would indicate a single loop. This could be a single 6' x 6' or a long loop such as a 6' x 50'
QuadrapoleTM. The remaining three settings indicate the number of 6' x 6' loops installed in
a single lane of traffic.
OPTION 8, COMMON FAIL OUTPUT (OPTIONAL OPTION)
The Common Fail Output setting shall be toggled ON or OFF by momentarily pressing either
the up or down button. The Common Fail Output setting shall be a "detector wide" option.
This means that setting it to ON for any channel turns it ON for all channels, and setting it
to OFF for any channel turns it OFF for all channels.
When Option 8 is enabled (on), a failure on any channel in the detector will cause all
of the fail outputs for the detector to activate.
OPTION 9, THIRD CAR PASSAGE
Each channel’s Third Car Passage setting can be toggled ON or OFF by momentarily pressing
either the up or down button. Option 9 is a “paired channel” option. This means that it
takes two channels to implement the feature. Therefore, when this option is toggled ON or
OFF in one channel, its paired channel is also set to the same state. Option 9 shall be
mutually exclusive with Option 10. Turning ON one option shall automatically turn OFF the
other option.
When Option 9 is enabled (on), the output of the paired channels shall be logically
ANDed together. This means that while the loops for both of the paired channels are
occupied, a call will output on both channels. While only one channel is occupied, or neither
channel is occupied, a call will not output for either channel. The first channel with
detection shall enter a “pending” state while waiting for detection in the other paired
channel. While in the pending state, the LCD shall show “Pnd” on the display.
OPTION 10, DIRECTIONAL LOGIC
Each channel’s Directional Logic setting shall be toggled ON or OFF by momentarily pressing
either the up or down button. Option 10 is a “paired channel” option. This means that it
takes two channels to implement the feature. Therefore, when this option is toggled ON or
OFF in one channel, its paired channel is also set to the same state. Option 9 shall be
mutually exclusive with Option 10. Turning ON one option shall automatically turn OFF the
other option.
When Option 10 is enabled (on), directional logic shall be enabled. Direction logic
starts with a detection on one channel. This channel shall go into the “pending” state,
display “Pnd” on the LCD display, and NOT output a call. When both of the paired channels
have detection, the last channel to have detection will output a Call until the detection for
the last channel ends, even if the detection ends for the first channel. None of the timing
functions of the first channel with a detection shall time (Delay, Extension, Max Presence,
and Detector Disconnect) and the first channel shall always operate in the Presence Mode
regardless of programming for the channel. The second channel with a detection shall time
all timing functions as programmed.
OPTION 11, AUDIBLE DETECT SIGNAL
Each channel's, Audible Detect Signal setting shall be toggled ON or OFF by momentarily
pressing either the up or down button. Only one channel can be turned on at a time.
Turning this option on for one channel automatically turns it off for the other channel. When
this option is enabled (on), an audible signal will be activated whenever the detection zone
for the selected channel is occupied. The audible signal indicates actual occupancy of the
SP 32
loop detection zone. Timing and disconnect functions shall have no effect on the audible
signal. This option shall be automatically disabled 15 minutes after activation or on loss of
power.
OPTION 12, DETECTOR DISCONNECT
Each channel's Detector Disconnect settings shall be toggled ON or OFF and the Extension
timer toggled between ON and OFF by momentarily pressing either the up or down button.
The Detector Disconnect feature requires that the Phase Green Inputs for each channel be
connected to the proper controller phase. When the Phase Green Input is not active (high),
the detector shall operate normally. When the Phase Green Input is active (low), at the end
of each detection the extension timer will start to count down. If this timer reaches zero
before the next detection, this channel will no longer output a call until the phase green
input is not active. Because the extension timer is used as a disconnect timer while in this
mode, two different disconnect types shall be available:
Option 12.1 OFF - Extension timing occurs and the extension timer also serves as the
disconnect timer during phase green. This will cause the Call output to remain in
the Call state until disconnect occurs.
Option 12.1 ON - Extension timing is disabled and the extension timer is used as the
disconnect timer. This will cause the Call output to follow the occupancy of the loop
detection zone until disconnect occurs.
