Setting the Relay Action 

Operation of the relays is programmed in the 

Action

 menu. The relays may be set up for 

any of the following modes of operation: 

1.  Automatic reset (non-latching) 

2.  Aut manual reset at any time (non-latching) 

3.  Latching (manual reset only, at any time) 

4.  Latching with Clear (manual reset only after alarm condition has cleared) 

5.  Relay alternation (automatic reset only) 

6.  Sampling (the relay is activated for a user-specified time) 

7.  Off (relay state controlled by Interlock feature) 

The following graphic shows relay 1 action setup; relay 2-4 are set up in a similar 

fashion. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 
 

Programming Set and Reset Points 

High alarm indication: program set point above reset point. 
Low alarm indication: program set point below reset point. 
The deadband is determined by the difference between set 

and reset points. Minimum deadband is one display count. If 

the set and reset points are programmed with the same 

value, the relay will reset one count below the set point.  

Note: Changes are not saved until the reset point has been 

accepted.
