12.1 Mechanical Operation Test:
A. Set the mode switches as follows:
1. Positions 1, 2 and 3 on.
2. Position 4 off.
B. Set the time switches to 00 to enter the
diagnostic mode. This mode enables the user to
increase the solenoid output rate to one pulse
every two seconds.
12.2 DPS-2 Test
A. Set the mode switches as follows:
1. Position 1 and 2 on.
2. Position 3 and 4 off.
B. Set the time dials to 00 to enter the diagnostic
mode.
C. This mode enables the operator to determine if
the DPS is operating properly. This is
accomplished by depressing and holding the test
switch. If the DPS is sensing flow in the pipeline,
the green LED should illuminate. If flow is not
present, the red LED should illuminate.
12.3 LCD Stroke Indicator Test Mode:
A. To test the stroke counter, set the mode
switches as follows:
1. Positions 1, 2 and 3 on.
2. Position 4 off.
B. Set the time switches to 00.
C. 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).
D. Set the configuration jumper to the far right
position marked stroke indicator test.
E. 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.
