RELAY RESET
User selectable via front panel buttons or digital inputs
1.
Automatic reset only (non-latching), when the input
passes the reset point.
2.
Automatic + manual reset at any time (non-latching)
3.
Manual reset only, at any time (latching)
4.
Manual reset only after alarm condition has cleared (L)
Note: Front panel button or digital input may be assigned to
acknowledge relays programmed for manual reset.
TIME DELAY
0 to 999.9 seconds, on & off relay time delays
Programmable and independent for each relay
FAIL-SAFE
OPERATION
Programmable and independent for each relay.
Note: Relay coil is energized in non-alarm condition.
In case of power failure, relay will go to alarm state.
AUTO
INITIALIZATION
When power is applied to the meter, relays will reflect the
state of the input to the meter.
