Emergency Shutdown
The terminals 105 & 106 on TB2 can be used for any eld
supplied component that requires a unit emergency shutdown.
When these terminals are used, the factory installed jumper
must be removed.
NOTE: Emergency shutdown Faults can be set to
automatically clear once the condition that caused
the alarm is corrected. This can be accomplished by
navigating to Commission Unit/Alarm Conguration/
Emerg Stop and changing the default No value to
Yes.

• Scroll up to “Apply Changes” and select “yes” which will
cause the controller to restart.
• Enter password 6363 then scroll down to “Commission
unit” and click on it.
• Scroll down to “Min OA setup” menu and click on it.
• Scroll down to Min OA reset and select “IAQ VDC” or
“IAQ mA” depending on the type of sensor installed.
• Scroll up to “Apply Changes” and select “yes” which will

On all style units (MPS/DPS/RTU/SCU) the CO

sensor
needs to be wired to terminals X1 and M at the Microtech III
Controller. Terminal M is the common for all analog inputs.
Make sure the eld wiring polarity is correct to read a valid
PPM value. See Table 4 on page 14
NOTE: The CO
2
sensor (and all eld installed devices)
must be powered from the same transformer as the
controller to prevent damage to the controller.
