TYPICAL APPLICATIONS (wiring diagrams)
Refer to Figure-1 for a service application wiring diagram showing the connections between
a CP-9301 or CP-9302 drive and an MP-3XX, MP-4XX, MP-21XX, or MP-97XX series
actuator. Figure-2, Figure-3, and Figure-4 diagram the connection of multiple actuators.

a Units with a “-2” suffix, e.g. MP-XXXX-XXX-2-X, include a built-in transformer (used for TAC Microtherm
®
or with AE-504) with secondary leads wired
externally to terminals 7 (Blue, 12 Vac) and 8 (Red, 24 Vac) of the actuator.
Caution
: When using the CP-9301 or CP-9302 with actuators containing an
internal transformer
, disconnect and tape off the red and blue leads before
installing and powering the device.
Failure to do so can result in damage to the actuator drive
.
Note
: Models prior to “-2” suffix had transformer wired directly to potentiometer. To disconnect the transformer, remove the back plate of the actuator, then
disconnect and tape the transformer leads.

2 As diagrammed, increasing input causes CW actuator rotation. All
references to the direction of rotation are determined by facing
the actuator output shaft.
3 The wires to terminals 7 and 8, and 2 and 3, may be reversed for
CCW rotation with an increasing input signal.
4 MP-XXXX-XXX-X-2 models are equipped with an external green
jumper from terminal X to the terminal block mounting screw
(ground). If the application requires it, this jumper may be
removed for isolation purposes.
5 24 Vac models are equipped with a jumper from terminal G to the
case ground screw.
6 The green/yellow wire must be installed under the terminal block
mounting screw.
7 Shield must be grounded to the terminal block mounting screw.

Caution:
Before installing the actuator drive onto
actuators equipped with an
internal transformer
, the
red and blue leads must be disconnected from
actuator terminals 7 and 8, and taped off.
Failure
to do so will result in damage to the actuator drive
.
8 Purge override (input signal override) is available on CP-9302
only. A dry contact closure from the override input (violet/white)
lead to the blue lead of the actuator drive forces the actuator to
drive to the end of travel, independent of the input signal
conditions. Connecting the violet/white and violet leads together
forces the actuator to drive to the opposite (high input signal)
end of travel, independent of input signal conditions.
