Optional High Limit Contact

The high CO2 limit option provides a dry (i.e. unpowered) 

contact closure that activates when the detected 

concentration rises above the high CO

2

 limit.  The high limit 

is adjustable from 0 to full scale of the unit 

Setting High Limit Contact Polarity

The polarity of the high limit contact is set with jumper JP5 

as shown in the table below. 

Jumper JP5 

Relay Operation 

OPEN

normally closed

opens above setpoint 

CLOSED

(factory default) 

normally open 

closes above setpoint 

To open jumper JP5 remove the shorting block from the two 

pins, and replace it so that it engages only a single pin of the 

jumper.  The shorting block should not be removed; it is 

required during the calibration procedure.
