A. Set the mode switch to position #5.
B. Set the data switches to 00.0 to enter the diagnostics
mode of operation.
C. Depress the enter switch to load the value into memory.
D. This mode of operation enables the operator to increase
the solenoid output rate to one stroke every two seconds.
E. Unscrew the thumb screws and remove the eight
position terminal strip and cover. This will expose the
battery pack and three position configuration jumper
(located in the lower right hand corner of the Z-200 controller
assembly).
F. Set the configuration jumper to the far right position
marked stroke indicator test.
G. This will cause all six digits to become active or display.
Press reset and a display should increment

actuates. When the display reads 999999, the test is
complete.
NOTE: when the test is complete, move the jumper back to
the factory position (far left).
