6.3.3.2 Function set to ALARM working mode
FEEDER CONTROL
Operates in response to the measured parameter. Can be set for phasing, set point, deadband,
overfeed timer, and ON/OFF delay.
2 POINT CONTROL Operates in response to the measured parameter using two setpoints.
WARNING
Activated when the analyzer detects a probe warning. Indicates warning and error condition of
selected probes.
PWM Control Allows the relay to provide a pulse width modulated output.
FREQ. CONTROL
Allows the relay to cycle at a frequency between the minimum pulses per minute and maximum
pulses per minute.
TIMER Allows the relay to switch at certain times independent of any process value
SYSTEM ERROR Indicates if a probe in the system has an internal error or warning
INPUT VALUE
The process value read from the selected source after it has been processed by the internal
formula parser (if prompted).
LOG INTERVAL
Default value: OFF
Sets the interval for logging the displayed value into the data logger.
Options: OFF, 5min, 10min, 15min, 20min, 30min
SYSTEM SETUP
RELAY
RELAY INT/EXT
ALARM
SET TRANSFER
Default value: DE-ENERGIZED
Sets the status of the relay (ENERGIZED/DE-ENERGIZED) if error conditions are detected in
the selected source or if the source is missing.
PHASE
Default value: DIRECT
Decides if the relay is turned on or off when the process value is leaving the controlled band.
DIRECT Relay is turned on when leaving the controlled band
REVERSE Relay is turned off when leaving the controlled band
HIGH ALARM
Default value: 15
Sets the maximum of the controlled band in the selected parameter unit.
LOW ALARM
Default value: 5
Sets the minimum of the controlled band in the selected parameter unit.
HIGH DEADBAND
Default value: 1
Sets the hysteresis value used at the upper limit.
LOW DEADBAND
Default value: 1
Sets the hysteresis value used at the lower limit
ON DELAY
(0 s–999 s)
Default value: 5 seconds
Sets a delay time for the relay to turn on.
OFF DELAY
(0 s–999 s)
Default value: 5 seconds
Sets a delay time for the relay to turn off.
