• SERIAL COM1/2 FAILURE ALARM DELAY: If loss of communications to the external master is required
to activate an output relay, select a time delay in the range of 5 to 60 seconds. In this case, an absence of
communication polling on the RS485 communication port for the selected time delay will generate the
alarm condition. Disable this alarm if communications is not used or is not considered critical. This alarm is
not available on the front RS232 port.
• CLOCK NOT SET ALARM: The software clock in the PQM will remain running for a period of approxi-
mately one hour after power has been removed from the PQM power supply inputs. Selecting
ON
in this
message causes a "CLOCK NOT SET ALARM" to occur at power-up for power losses greater than one
hour. Once the alarm occurs, the clock setting on
S1 PQM SETUP \ CLOCK \ SET TIME & DATE
must be stored
to reset the alarm.
• DATA LOG 1 / 2 MEMORY FULL LEVEL: These messages can be used to configure alarms to indicate
that the Data Logger memory is almost full. Separate alarms are provided for each log. When the log mem-
ory reaches the level programmed in this message a DATA LOG 1 / 2 Alarm will occur.
