Relay and Alarm Operation 
Diagrams 

The following graphs illustrate the operation of the 
relays, status LEDs, and ACK button. 

High Alarm Operation (Set > Reset)

  

 

For Manual reset mode, ACK can be pressed anytime to turn "off" relay. To 
detect a new alarm condition, the signal must go below the set point, and then go 
above it. 

 

Low Alarm Operation (Set < Reset) 

 

For Manual reset mode, ACK can be pressed anytime to turn "off" relay. To 
detect a new alarm condition, the signal must go below the set point, and then go 
above it. 

High Alarm with Fail-Safe 
Operation (Set > Reset) 

 

Note: Relay coil is energized in non-alarm condition. In case of power failure, 
relay will go to alarm state. 

 

Low Alarm with Fail-Safe 
Operation (Set < Reset) 

 

Note: Relay coil is energized in non-alarm condition. In case of power failure, 
relay will go to alarm state.
