3.
Unscrew
the thumbscrews and
remove
the six position terminal strip and cover.
This will expose the battery pack and
the three position configuration jumper
(located in the lower right corner of the
Z-65 controller assembly).
4.
Set
the configuration jumper to the far right
position marked stroke indicator test as
shown.
5. This will cause all six digits to become
active on the stroke counter.
Depress
the
reset. The stroke counter should increment
000000, 111111, etc., up to 999999 each
time the solenoid fires. When the counter
display reads 999999, the test is complete.
NOTE:
When the test is complete, move the
jumper back to the factory position (far left
position).
LCD Stroke Indicator Test Mode:
1.
Set
the mode switches 1, 2 and 3 to ON
