Chapter 4: Maintenance and Trouble Shooting

The following procedures are intended as an aid to isolate system malfunctions down to fi eld replaceable elements. These ele-

ments include; controller, output module, transducer and interconnecting wiring.

Preliminary Checks

Check System connections at the transducer, junction box, controller and output module to ensure that all connectors and wires

are secure. A slight tug on each wire at the controller is recommended. Verify that all wiring to the controller and output board

is in agreement with the data plates.

Check input power to the controller and output board. Input voltage should be from 105 to 125VAC. Verify line fuse on output

board has not blown.

Malfunction Analysis

Unit powers up with EE POS

Problem:

Cause: There are several probably causes for this error message. To check system for cause, depress F - 1 - 6 - ENT. This

causes the unit to display a trouble fl ag, shown below:

EE0001 =

EE0010 =

EE0100 =

EE1000 =

interference input.

EE0000 =

Note: If more than one error exists, a combined error message will be displayed. Ex.: a slide gap interference fault and lower

limit exceeded fault occur at the same time, an error fl ag of EE1010 shows.

To trouble shoot fl ags:

1. EE0001

- Shows that a transducer signal loss has occurred. Check all transducer connections. If all connections are

made, check circuit integrity (see transducer information sheet).

2. EE0010

- Lower limit exceeded. The electronic lower limit has been exceeded. Putting the keyswitch in the Jog

Mode and moving the slide out of this zone (jog up) will reset this fault.

3. EE0100

- Upper limit exceeded. The electronic upper limit has been exceeded. Putting the keyswitch in the Job

Mode and moving the slide out of this zone (jog down) will reset this fault.

4. EE1000

- The slide gap interference switch has been activated. Depending on which slide is being monitored, a

jog move will have to be made to bring slide out of the slide gap interference zone. Or 110 V.A.C. has been

lost on slide gap

interference switch when F - 20 - ENT is set for option 1 or 2.

Unit reads EEEEEE

Problem:

Cause:

persist, check diagnostic code.

Signal loss

Lower limit exceeded

Upper limit exceeded

Slide gap interference fault or loss of 110 V.A.C. on slide gap

All are correct

This is due to a programming error. Depress the clear (C/CE) key. Now reprocess sequence. If EEEEEE's
