Cleanout Plunger Proximity

Switch Replacement

The proximity switch on the cleanout plunger is a

high-pressure switch that extends directly into the

hydraulic fluid. The quick-disconnect feature on the

switch allows easy replacement of a failed or damaged

switch or cord set.

Tools Required

• 1 in. open-end wrench

Cord Set Replacement

1. Disconnect the cord set (BA) from the machine at

the Amphenol connector (BB).

2. Unscrew the knurled knob at the end of the cord

set (BA) and disconnect the cord set from the prox-

imity switch (BC) on the MixHead.

3. Match up the keys on the cord set (BA) with the key-

ways on the proximity switch (BC), insert the cord

set into the proximity switch, and tighten the knurled

knob.

4. Connect the cord set (BA) to the machine at the

Amphenol connector (BB).

• Do not operate the MixHead unless all proximity

switches are in place and the proximity switch

alarm is operational and armed.

• A shock hazard or unpredictable machine operation

could occur if the proximity switch is separated from

its mating cord set, or if either the proximity switch

or its mating cord set are used with a different

switch or cord set.
