Alarm Messages
Programmer alarms interrupt Manual display,
as discussed in "Keyboard Operations". This
prevents important error messages from being
lost while the Manual display is activated.
Once any of the following alarms are displayed
and/or sounded, the dual-key operation
Shift/"down arrow" cannot be used until the
alarm is silenced by pressing Enter. This does
not clear the alarm, however.
Programmer Alarms appear at Event 0 on the
Optomux board.
To respond to alarm displays (#01-#98)
1. Press Enter one time to deactivate alarm
relay contact (silence).
2. Examine the display to determine the origin of
the system alarm:
Messages #01-79:
Indicate a programmed alarm (from an
"A-ALARM" OPCODE in the program) has
occurred. The response should be to carry out
whatever task the message code indicates. For
example, Message #37 might mean put test pins
in furnace, while #28 might mean to manually
change the temperature setpoint to 1550`F.
These codes should\d be assigned for the
particular installation involved.
