Delay

The alarm actuation can be delayed for either, or both, 

ON

 alarm and 

OFF 

alarm conditions.

•

 

Set 

S1-1

 and 

S1-2

. (Refer to Setup\ Switch Bank on p. 19.)

•

 

Adjust the delay time from 1 to 60 seconds by setting potentiometer 

P1

Operation

After completing the setup, replace the Pointek CLS lid and lid clip. The unit is now in service,

providing level detection of your process.
