2.9.1 Set Relay Normal States
The PAL-AT relays can be set normally open (de-energized) or normally closed (energized). An alarm
switches the relays to the opposite state. The labels on the relay terminal strips (see Figures 2.1.3A,
2.1.3B and 2.1.3C) refer to the form C contacts in their open or de-energized state.
PAL-AT is shipped with the relays configured for normally closed (energized) operation. To
change the relay operation press 1 and # from the Special Function Menu. The message is:
LCD98:
Press * or # to select the desired state of the audible alarm relay, the relay controlled by the silence
feature. The next message is:
LCD99:
This message is displayed if any cable cards are version CSS 7102 I or later. (Version CSS 7102 I has
6 LEDs). The relay logic is set by moving the "Relay Setup" jumper on each cable card (see Figure
5.3A).
The cable relay can be set to activate in response to a "Leak" and ignore other faults, such as, "Break",
"Short", "No End Found", etc. The alarm relay will still activate in response to all alarms. The next
message is:
LCD100:
The factory default is no. This will cause the relay to activate for all cable problems.
