  • Page 12: Section 2 General Characteristics

    Section 2 General Characteristics 2.1 INPUTS 2.1.1 AC LINE The over-current protected side of 120 volt AC 60 hertz source. This input (Connector A - Pin A) is used to generate the voltages required to operate the monitoring logic. The monitor has a front panel mounted over-current protection device in the 120 volt AC input to the unit.

  • Page 13: Logic Ground

    The presence of the proper voltage at this terminal also enables Minimum Yellow Change / Red Clearance Interval Monitoring and Field Check / Dual Indication Monitoring. The absence of the proper voltage at this terminal inhibits Minimum Yellow Change / Red Clearance Interval Monitoring. The monitor will not recognize state changes of the Red Enable input while AC power is not valid.

  • Page 14: Port 1 Disable

    2.1.13 PORT 1 DISABLE The Port 1 Disable input (Port 1 SDLC Connector - Pin 10) is a logic level input. When this signal is in the low state (nominal 0 volts), the monitor will ignore Port 1 SDLC communications errors. Port 1 SDLC communications errors are always ignored during type 12 operation.

  • Page 15: Channel Compatibility

    2.3.1 CHANNEL COMPATIBILITY The monitor requires programming action to provide compatibility between channels. The programming card has 120 pairs of holes for channel compatibility programming jumpers. The 120 jumper hole pairs are logically labeled for easy identification of the jumper holes by channel pairs. A soldered wire jumper in a jumper hole pair defines a pair of channels as permissive or compatible.

  • Page 16: Reset

    2.4.3 RESET Activation of the front panel reset pushbutton or the reset input causes the Output relay contacts to transfer to the no fault condition. The monitor remains in the no fault condition only if there are no existing faults and all input voltages are at the proper operating levels.

  • Page 17: Up Time Accumulator

    from the Controller Time setting by five (5) or more seconds, the Real Time Clock will be synchronized to the Controller clock and an entry will be made to the Time Change Log. External Time Source (i.e. laptop computer) - The Real Time Clock setting can be modified through the use of the RaeComM software.

  • Page 18: Red Fail Monitoring

    conflicting displays are detected a conflict timer is started. If the conflict goes away the conflict timer is stopped (it is not cleared) and a non-conflict timer is started. If the conflict reappears the non-conflict timer is reset to zero and the conflict timer continues timing from its prior value.

  • Page 19: Dual Indication Monitoring

    Modifying Inputs: Red Enable: All red fail testing will be disabled when this input is below 70V Load Switch Flash bit (bit 112) of the Type 0 Frame: All red fail testing will be disabled when this bit is set to one.

  • Page 20: Gy-Dual Indication Monitoring

    Minimum Yellow Change Disable Jumpers: When Minimum Yellow Change Disable is jumpered for a channel the Red + Yellow fault timing threshold for the single indication timer is changed from 1000 milliseconds to 400 milliseconds. Flashing Greens (also known as Canadian Fast Flash): When Flashing Greens are enabled the no indication timer thresholds for the Green + Red and Green + Yellow fault conditions are changed from 300 milliseconds to 100 milliseconds.

  • Page 21: Short Clearance Monitoring

    the Yellow was skipped. When a Yellow turns on for at least 100 milliseconds another 2.7 second timer is started and must reach zero before the yellow turns off or a short Yellow fault will be generated. The normal voltage thresholds for this test are: Reds –...

  • Page 22: Field Check Monitoring

    2.5.7 FIELD CHECK MONITORING Configuration: All channels with a setting of “Y” for Dual Indication / Field Check will be monitored for a field check fault. The testing defaults for this feature are all channels enabled for field check testing. Test Preformed: This monitoring function combines information about active field inputs with information received through the Port 1 communications between the Controller Unit and the monitor in a TS 2 Cabinet Assembly.

  • Page 23: Volt Monitor I

    2.5.9 +24 VOLT MONITOR I Configuration: The 24V Latch jumper on the Program Card determines whether this fault is a latched fault. The testing default for this feature is determined by the jumper installed on the program card. Typically no jumper is installed during automated testing.

  • Page 24: Local Flash

    Fault Action: The monitor transfers the Output relay contacts to the fault condition (continuity between the Normally Open and Common contacts), illuminates the CVM / WD indicator on the front panel, and sets the Controller Voltage Monitor bit (bit 57) of the Type 129 Frame to 1. The Signal Sequence log will record this fault. The Prior Faults log will record this fault if Log CVM Events is enabled.

  • Page 25: Programming Card Absent Monitoring

    Feature Interactions: None 2.5.14 PROGRAMMING CARD ABSENT MONITORING Configuration: None Test Preformed: If the programming card is not present or not seated properly in the connectors the monitor generates a fault. Fault Action: The monitor transfers the Output relay contacts to the fault condition (continuity between the Normally Open and Common contacts), illuminates the PRGM CARD indicator on the front panel.

    FYA Solo – The Solid Red, Yellow and Green Arrow indications come from the Parent channel. The FYA will come from a child channel. FYA 1-4 Yellow - This affects parent channels 1-4. When ON the FYA is driven by a Yellow output of the child channel.

  • Page 27: Per Channel Red Enable

    With LED thresholds, the monitor senses Greens, Yellows, Reds, and Walks are sensed as ON when their voltage is above 70V and OFF when below 50V Dual Indication: Normal dual indication testing senses Greens, Yellows, and Walks as ON when their voltage is above 25V and OFF when below 15V .

  • Page 28: Disable Local Flash

    Tests Modified: +24 Volt Monitor II: Normal +24 Volt Monitor II testing checks for the +24V Monitor II (Connector B - Pin R) input being greater than +22V . When this feature is enabled, a voltage greater than +11.5V applied to the +24 Volt Monitor II input is recognized as adequate for proper operation.
