Overview Port 1 Disable Input Monitoring In the type 16 mode port 1 can be defeated by grounding the Port 1 disable pin in the Port 1 connector pin 10 see page 123 When defeated the MMU will operate in the 16 channel configuration but without requirement of Port 1 communications Type Monitoring The MMU type 12 or 16 is determined by MMU Port A connector pin HH If the input changes state the reset key must be manually pressed once to initially configure the Double Diamond for the new type This prevents the unit from inadvertently changing states on its own in the field due to a field input change say due to a bad input or weak connection Thus if the type pin HH changes but the Double Diamond MMU is still configured the old way i e it has not been manually reset since the change then a TYPE FAIL will be registered This is a latched failure requiring manual reset which will re configure it Programming Card Monitoring Whether or not the Programming Card has any jumpers it must be inserted and properly seated into the MMU If unable to detect the presence of the card a Card Failure will be declared by the MMU and the output relay will drop This is a latched failure requiring manual reset A Card Fail also occurs if two cards are inserted only one allowed or ifa TS 1 card is inserted when the Type 16 mode is selected pin A HH Logic ground true Field Check Monitoring This monitoring feature requir

14. Controller Output Fault Monitoring OVERVIEW OF OUTPUT MONITORING The following topics describe the variety of controller outputs and output combinations that can be monitored by the Double Diamond MMU Conflict Monitoring A conflict occurs when any combination of Green Yellow or Walk GYW inputs are active on two or more non compatible channels for a specified period A pair of non compatible channels are two channels which do not have a jumper installed on the MMU s Programming Card Refer to page 25 for details about the Programming Cards Conflict Recognition Time The time to recognize a conflict is 325 125 milliseconds in the standard mode This is the minimum time required for G Y Walk signals to be ina conflicting state before they will be registered as a conflict and the output relay trips Thus G Y W signals conflicting less than 200 milliseconds must not cause a conflict and G Y W signals conflicting for more than 450 milliseconds must cause a conflict An option called Fast Flash can be turned on to lower this conflict recognition time to approximately 150 milliseconds for Canadian intersections Green Yellow Walk Signal Thresholds The MMU expects signals to be at least 20 5 VAC RMS when ON Therefore Green Yellow and Walk signals of less than 15 volts AC must be considered OFF and signals above 25 volts AC must be considered ON Signals from 15 to 25 may be considered either

In this case CVM FAIL will be displayed Normally this will clear after a few seconds 2 10 secs and the intersection will begin running If a CVM failure occurs after the controller cabinet has been running and CVM has once been good then CVM FAIL or CVM LTCH will be displayed depending on the latch mode option keyboard entry when TS 1 card inserted jumper on the program card if TS 2 card This generally a sign of some type of controller failure see page 87 CVM during power up initialization after the MMU Min Flash timing if CVM has not yet been valid Shows that CVM has not been valid yet This display should clear in a few seconds after the controller has fully initialized Channel 1111111 1234567890123456 C F V A IM I L Figure 82 Power up CVM fault display Note that this display only occurs if CVM is not valid by the time Min Flash times out Usually it is and this display does not appear If it does appear it would be as shown for either non latch or latch modes CVM must go to the valid state once before latch is enabled Non Latched CVM Fail Display After the CVM signal has been established as good by the controller and the system subsequently reports a CVM error this is the display that is shown by the MMU It is the same display as above except that CVM has once been good This fault can clear if the controller returns its CVM output back to the good state Double Diamond MMU Operating Man
30. OFF or ON Red Signal Threshold The MMU expects the red signal on a channel to show at least 60 10 VAC RMS when ON Thus a channel s Red signal of less than 50 volts AC must be considered OFF and a red signal above 70 volts AC must be considered ON A red signal from 50 to 70 may be considered either OFF or ON Red Failure Monitoring Red failure occurs whenever all signals are absent below threshold on a channel for a specified period In other words each channel must have at least one R Y G or walk in TS 1 or type 12 modes input above threshold at all times Red failure is a familiar term but often misinterpreted A better term would be signal loss because absence of any signal can cause the failure For example if a load switch fails to display green when it should then a red failure will occur even though the green driver is at fault and the red driver may be fine Regardless of appropriateness Red Fail is the term used Red Fail Recognition Time The minimum Red Fail recognition time is 850 125 milliseconds This is the minimum time all the signals must be absent below threshold on a channel to cause a Red Failure Red Enable Input Red failure monitoring is only executed when the AC Red Enable input is active 120 VAC Red Enable is usually controlled by the cabinet signal bus system so that red monitoring only occurs during automatic operation and not in flash or when
