RSMVQ2R Inputs Wiring
RSMVQ2R Wiring
The RSMVQ2R connects to the VCCX2 Controller using an
EBC E-BUS cable. Only one RSMVQ2R can be connected.
There are two E-BUS Expansion Ports which allow the use of
communicating sensors and the E-BUS Modules.
The RSMVQ2R uses four analog inputs, two binary inputs, four
relays, and two analog outputs. See Figure 2, this page for inputs
wiring and Figure 3, page 9 for outputs wiring.
Head Pressure Control
The RSMVQ2R can monitor the Head Pressure Transducers and
control Condenser Fans to maintain a Head Pressure Setpoint.
The Condenser Fans will be controlled with a 0-10 VDC output
signal.
Condenser and Compressor Configuration
Options
Please see pages 31-34 for Condenser and Compressor
Configuration details.
WARNING:
Observe Polarity! All boards must be wired
with GND-to-GND and 24 VAC-to-24
VAC. Failure to observe polarity will result
in damage to one or more of the boards.
Expansion modules must be wired in such
a way that the expansion modules and the
controller are always powered together. Loss
of power to the expansion module will cause
the controller to become inoperative until
power is restored to the expansion module.
