Operation and Maintenance Instructions
Remedy
For a 5-Probe Assembly:
Simulate "Low Water Condition"
After cleaning the probes, lift probe assembly out of the stand pipe .
This will simulate a "low water condition" . Check the contacts for
proper position .
- Differential Contacts: C to NC - closed - Water make-up valve
energized - LED = OFF
- High Alarm Contacts: C to NO - open - High alarm circuit
de-energized - LED = OFF
- Low Alarm Contacts: C to NC - closed - Low alarm circuit
energized - LED = OFF
Simulate "High Water Condition"
Connect a jumper wire between the longest probe (ground) and
all other probes (high limit, high alarm, and low alarm) . Check the
contacts for proper position .
- Differential Contacts: C to NC - open - Water make-up valve de-
energized - LED = ON
- High Alarm Contacts: C to NO - closed - High alarm circuit
energized - LED = ON
- Low Alarm Contacts: C to NC - open - Low alarm circuit de-
energized - LED = ON
