CM2M-K
Commonly asked questions
•
When installing with a three phase fan, interlock using just one phase of the fan.
•
Always install the current monitor before any speed controllers or invertors.
•
A flashing green power LED indicates that a jumper link is missing from one of the “course sensitivity
headers”, both A & B links must be fitted even if only using one side of the CM2M-K
•
When a fan is first switched on and the power drawn is detected, the corresponding “Running LED” will flash
red for the first 15 minutes running and then become solid. This can be used to help diagnose a fan which is
intermittently cutting out.
•
The current monitor will detect a current as low as 30mAmps, if when the fans are switched on you do not
have a red flashing check the sensitivity adjustment hasn't been raised too high.
•
Wire the connection for any supply air into the main panel terminals S1 and the extract air into E1, this will
allow correct reporting of the fans in the LCD screen.
•
If you only have extract air/one fan installed (and connected to E1) leave the shorting link fitted into S1 to avoid
the main panel waiting for another fan start.
