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.
COUNTER
:
The WT-25 Label Rewinding Machine has a 'count by length' counting system. This system consists of a counter, a counter circuit board (which
plugs into the rear of the counter), a Counter Drive Roll (this has one magnet in the bottom), and two magnetic proximity switches called reed
switches that are mounted in the tabletop surface itself just underneath the counter drive roll. The circumference of the standard counter drive
roll is 10" (12" or Metric 10cm counter drive rolls are also available). Each revolution of the standard counter drive roll represents 10" of web
travel and increments the counter by one.
Parts for a WT-25 Series Counting System include:
Counter 85-1302 for WT-25 or
Counter Circuit Board 01-1113 for WT-25 or 01-1107 for WT-25LC & WT-25LCI
Reed Switches (2) 26-1101 (all models)
Wiring Harness from Counter Circuit Board to Reed Switches
Wiring Harness from Counter Circuit Board to Main Circuit Board
Counter does not light up

Ask them if the LED lights on the counter circuit board are lit. If not, then the counter may need replacing.

Check for 115v power to terminals 11 & 12 at the back of the counter (not at back of the circuit board). If there is 115v to the back of
the counter at terminals 11, then replace the counter. If there is no power at terminals 11 & 12, then check for a blown fuse, a broken
wire in the wiring harness, whether the machine's power switch is on, or is there a power outage at the receptacle where the machine is
plugged.
Counter Won't reset to Zero when pressing green stop button after reaching stop count (Length Mode Only)

Check the ice cube relays to make sure they are seated properly with good connection

Replace Counter to see if that cures the issue, if not then, replace counter circuit board.

If neither new counter or new counter circuit board does not cure problem, check wiring behind green start button or replace button.

Check Wire #21 for broken wire bad connection.
