TB1 Terminal Block (CO

Reading)

The TB1 terminal block should only be used to test the sensor when the

sensor cable is plugged into the controller and the sensor and controller

are powered up. Directions: Set the meter for DC volts and connect

the GND probe to the GND terminal and the + probe to the CO

0-5

terminal. Look at the output voltage and record it. Multiply the voltage

times 400. The value should match the CO

as read on the System Man-

ager TS, Modular System Manager, Modular Service Tool, or Prism. If

the signal doesn’t match the sensor reading, call WattMaster Controls

for a replacement.
