Description
Resets the overfeed timer
Sets the event setpoint
Sets the event phase (0 = Low; 1 =
High)
Sets the event deadband
Sets the max on time (mins)
Sets the min on time (mins)
Sets the max off time (mins)
Sets the min off time (mins)
Sets which Sensor outputs are affected
during timer on time (0 = None;
2 = Selected Sensor; 13 = All Sensors)
Selects which Sensor outputs are being
held/transferred during the timers on
time (this is used when Hold type is set
for single Sensor)
Selects hold outputs vs. set transfer
value during timers on time
Sets the timer on duration time (sec)
Sets the period between timer on events
(mins)
Sets the time the affected Sensor
outputs are held/transferred after the
timer turns off (sec)
Sets the status level which will trigger
the relay
Selects data source for this relay
(0 = None; 1 = Real Time Clock;
2 = Sensor; 4 = Calculation)
Selects Sensor source when Source =
Sensor (0 = Sensor1; 1 = Sensor2)
Selects measurement on the Sensor
(0 = Meas1 .. 3 = Meas4)
Selects the relay type (0 = Alarm; 1 =
Control; 2 = Status; 3 = Timer; 4 =
Event)
Selects the transfer value for the relays
(0 = De-energized; 1 = Energized)
Sets the high alarm setpoint
Sets the low alarm setpoint
Sets the high alarm deadband
