Web Techniques WT-25 Series Troubleshooting Guide
SAFETY WARNING: BEFORE PERFORMING ANY REPAIR TO WEB TECHNIQUES EQUIPMENT, YOU MUST TURN OFF
THE POWER AND DISCONNECT THE EQUIPMENT FROM THE POWER SOURCE.
Machine Only Runs One Direction
Direction Switch needs replacing? Check to make sure that one of the wires has came off the back of the switch.
Motor Control has a bad SCR (reversing module), if so, replace motor control (See Motor Control Testing).
Machine is Stuck in Idle Mode
Relays in the counter could be stuck, replace counter.
K3 Decel Relay is bad or loose or missing, (you can test this be swapping it with the K2 stop relay-they are the same relay)
Bad Connection in the wiring harness from counter circuit board to main circuit board.
Machine Won’t Stop
Possibly it is a bad motor control
If you flip the direction switch while the machine is running, does it change directions, if not, possibly bad motor control or direction
switch.
Machine Only Runs When Pressing (and holding) Green Start Button
Chances are the K1 Relay has wiggled out of its socket enough to lose contact. Check the relays to make sure they are pushed in all the
way. Check that wires are properly connected on the back of the Green pushbutton switch and on the main circuit board.
Possibly wire #9 in the plug to the right of the K1 Run Relay may have lost connection. This wire runs from the green start button
through the stop button to the connector next to the K1 relay on the main circuit board.
