ELECTRICAL TROUBLESHOOTING

PROBLEM--Traverse does not stop to reverse directions when flag goes under the proximity switch on the left side or right side of machine.

Possible Cause

Gap between flag and prox is incorrect. Proximity Switch is bad.

Checkout Procedure

A. Gap between flag and prox should be 3/16 to 1/4" (4-6 mm). Prox LED does not light when flag is under prox.

B. Proximity switch is not working properly or wire connections are loose.

If incorrect, adjust per adjustment section of manual. Yes--end troubleshooting No--go to Step B. next

First check to see if proximity light comes on. When the light is on, it means that there is electricity coming to proximity switch. Actuate prox switches with steel tool to take measurements.

Left proximity (PROX 1) check Traverse drive Control (TDC) between terminals #13 (black wire) and #15 (brown wire).

Right proximity (PROX) check #14 (black wire) and #15 (brown wire).

The light coming on shows the proximity is getting electrical contact.
