4.4.1 The Service Program

Among the features of the electronics is a service program containing a number of

codes. These codes are listed on succeeding pages, along with the adjustments they

control. Each code tests relay output and digital input.

To Run the Service Program:

1. Switch the processor off.

2. Press the following keys in the sequence shown:

AUTO

DRYER SAVER

TIME

The display should read:

Service Code ___.

The service codes are represented by a three-digit number. The keys DEV,

FIX, and WAT can be used for choosing this three-digit number.

NOTE: DEV = 1, FIX = 2, WAT = 3.

To choose, for instance, code 132, press:

DEV

WAT

FIX

The display should read:

Service Code 132

(This is not the case when a service code is chosen which uses the dis-

play).

3. Start the test by pressing the 15% key.

4. Stop the test by pressing the 85% key.

5. Return to the service menu by pressing the 50% key.
