BMC and BMC-6X Installation and Operation Manual

WIRING TO MODULATING MOTORS

The BMC can modulate any combination of the following motors. The Output Type must be selected properly before connecting any output wires to avoid damage components. See Output Type on page 11.

WIRING THE 4-20MA MODULATING MOTORS (A TERMINALS 13, 14), (B TERMINALS 16, 17),...

•The BMC can operate up to four 4-20 mA modulating motors.

•The BMC-6X can operate up to six 4-20 mA modulating motors.

•The BMC and the BMC-6X sources 24VDC excitation voltage for the 4-20mA signal.

•Wire the (-) from the modulating motor to the boiler terminal on the BMC 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 BMC marked (mA). That is for boiler A, the modulating (-) terminal will be 14.

WIRING THE VOLTAGE MODULATING MOTORS (A TERMINALS 13, 15), (B TERMINALS 16, 18),...

•The BMC can operate up to four 0-5V, 0-10V, 1-5V, or 2-10V modulating motors.

•The BMC-6X can operate up to six 0-5V, 0-10V, 1-5V, or 2-10V modulating motors.

•Wire the (GND) from the modulating motor to the boiler terminal on the BMC marked (GND). That is for boiler D, the modulating (GND) terminal will be 22.

•Wire the (V+) from the modulating motor to the boiler terminal on the BMC marked (VLT+). That is for boiler D, the modulating (V+) terminal will be 23.

CONNECTING TO THE BMC-6X PANELS

•The BMC is equipped with a 6-pin phone socket (RS485) to connect to extension panels. The BMC-6X is equipped with two 6-pin phone sockets to connect to BMC and an additional BMC-6X.

•Configure the Output Types (see page 11) after connecting the Extension panels to be able to configure their outputs.

•Only 6-wire phone cable must be used for proper operation.

•Connection cable is provided as part of the BMC-6X package.

•Phone cables must be of a 6-wire with 6-pin terminals. Phone cables can extend up to 100'.
