OPTIONS
Relays
RATING
2 or 4 SPDT (form C); rated 2 Amp @ 30 VDC or 2 Amp @ 250 VAC resistive load;
1/14 HP @ 125 / 250 VAC for inductive loads.
RESET
User select
- Automatically when the input passes the reset point.
- Automatically + manually (via user supplied switch or front panel ACK button). Manual reset resets all manually resetable relays.
FAIL-SAFE OPERATION
The relay coils are energized in the non-alarm condition. In the case of a power failure, the relays will go to the alarm state. Fail-safe
operation by removing jumper J2 located on the Options PCB.
AUTO INITIALIZATION
When power is applied to the meter, the relays will always reflect the state of the input to the meter.
DEADBAND
0-100%, user selectable
