The screw terminals, located on the Printed Circuit Board
(see Fig. 3), are suitable for connecting 0.3 to 1.5 mm
(16...22 AWG) wiring. The assignments of terminals 1
through 7 for both models are depicted in Fig. 4 and Fig. 5.

CONFIGURATION
The wall module can be configured using its configuration
jumper and/or its configuration potentiometer.
Configuration Jumper
The wall module's calibration modes can be selected and the
CO
measuring range extended by repositioning the con-
2
figuration jumper located on the Printed Circuit Board (see
Fig. 3).
IMPORTANT
Do not change the position of the configuration
jumper before first removing power.
In a normal environment, the unit is maintenance-free.
Accurate measurement is guaranteed by the built-in ABC self-
calibration feature (see below).
Setting Range to 2000 ppm or 3000 ppm
"2000" ppm
When the configuration jumper is set to the factory default
position of "2000" ppm (see Fig. 9) – or to any other position
except "3000" ppm (see Fig. 6) – the CO
400...2000 ppm.
