General Alarm DO
The General Alarm DO sets the operation of the general alarm relay digital
output when a general fault alarm occurs. The relay is normally energized
making it fail-safe for detection of not only alarms, but also power failures.
Enter 0 to make the relay latching, which means any general fault alarm will
de-energize the relay and keep it de-energized even if the alarm condition
clears. This parameter must be reset to return the relay to ‘normal’ state. Enter
a 1 to make the relay non-latching, which means any general fault alarm will
de-energize the relay; however, when the alarm condition clears, the relay will
automatically reset to its normal state. Enter a 2 to reset the relay and any
active alarms to the ‘normal’ state. After the relay resets, this parameter will
automatically revert to the setting from before the reset was initiated.
High Alarm Setpoint
The High Alarm Setpoint parameter determines the concentration threshold
above which the Concentra High Alarm fault will be triggered (refer to
“Alarms” on page 2-42). The value entered is compared to the moving
average over the number of measurement points set by the Logger Rate. The
setpoint must have a value greater than the maximum range of the analyzer
or maximum dew point to be turned off.
Keypad Watchdog
The Keypad Watchdog parameter sets the allowable time (in seconds) that
the analyzer can be on the MODE screen and the Mode 2 (Set Parameter
Mode) password screen before automatically reverting to Mode 1 (Normal
Mode). Setting this parameter to a value less than five (5) will disable this
feature. If it is set for greater than or equal to five (5), then the value
represents the number of seconds before the analyzer reverts to Normal Mode.
