RCM Sections

Refer to the illustration of the Rack Control Module (RCM) to the left and note the three outlined sections. The sections are labeled and the function of each section is explained below:

Input Section —

Output Section —

Red lights show the state of the inputs to the RCM.

Green lights show the outputs from the RCM to the machine.

RCM Status/Jumpers — The red RUN indicator shows

that the RCM is energized.

The jumpers set-up the inputs and outputs for various machine models.

RCM Harness Connectors

Note the illustration of the RCM at left and the details from the machine electrical schematic #702260 to the right. These illustrations show the location and connections from the RCM to the dishwasher. The function of the connectors are:

H1 — Control Cabinet Inputs

H2 — Control Cabinet Outputs

H3 — Inputs from Junction Box

H4 — Heat Outputs

RCM Operation

The insert following this page gives a detailed explanation of the inputs, outputs and the status of the indicator lights on the RCM during normal operation of the machine.

Refer to these instructions and the electrical schematic for the operation sequence of the RCM and to aid in the troubleshooting of the dishwasher.
