WIRING TO MODULATING MOTORS
WIRING TO 4-20MA MODULATING MOTORS (A TERMINALS 13, 14), (B TERMINALS 16, 17), ...
•
The M4 can be equipped to operate up to four 4-20 mA modulating motors.
•
The M4-Extension can be equipped to operate up to six 4-20 mA modulating motors.
•
The M4 and the M4-Extension sources 24VDC excitation voltage for the 4-20mA signal.
•
Wire the (-) from the modulating motor to the boiler terminal on the M4 marked (GND). That is for boiler A,
the modulating (-) terminal will be 13.
•
Wire the (+) from the modulating motor to the boiler terminal on the M4 marked (mA). That is for boiler A,
the modulating (-) terminal will be 14.

CONNECTING TO THE M4-EXTENSION PANELS
•
The M4 is equipped with a 6-pin phone socket to connect to extension panels.
•
The M4-Extension is equipped with two 6-pin phone sockets to connect to M4 and an additional M4-Extension panel.
•
Only 6-wire phone cable must be used for proper operation.
•
Connection cable is provided as part of the M4-Extension package.
•
Phone cables must be of a 6-wire with 6-pin terminals. Phone cables can extend up to 100'.
