13.0 TROUBLE SHOOTING
Table 13.0
SYMPTOM
POSSIBLE CAUSE
REMEDY
Flow through monitor
with valve in closed
position
1. Debris or damage to the valve seat or half ball
1. Clean out debris or replace damaged parts.
Leaks on exterior
2. Debris or damage in an O-ring seal area
2. Clean out debris or replace damaged parts.
Valve will not open with
telescoping waterway
raised
3. Poor connection from UP reed switch
4. Poor connection to valve lock solenoid
3. Per Figure 8.5.1, verify continuity from Relay 3
terminal 85 to ground.
4. Verify 9 to 15 volts from Relay 3 terminal 87 to
ground.
Does not raise
5. Mechanical binding
6. Improper pressure balance at pneumatic cylinder.
7. Poor UP electrical connection
5. With switch in DOWN position and power off,
manually lift/lower telescoping waterway several
times per Section 10.3. Turn power on and switch
UP/DOWN several times to verify pneumatic
cylinder rod moves smoothly. Reassemble.
6. Per Section , press the built-in switch on the
upper solenoid valve (A) and verify less than 10
seconds to raise. If not, verify 80+ psi, then follow
the pneumatic calibration instructions.
7. Per Figure 8.5.1, with switch in UP position, verify
continuity from terminal 85 to ground, then verify
10+ volts from ground to the following 3 terminals on
Relay 1: 30, 86, and 87 (NO). Next, verify 9 to 15
volts at UP solenoid connection of direction control
valve by removing the Phillips head screw from the
connector and sliding it off the control valve.
Does not lower
8. Valve is OPEN
9. Improper pressure balance at pneumatic cylinder.
10. Poor connection from VALVE CLOSED reed
switch
11. Poor DOWN electrical connection
8. Close the valve before lowering the waterway.
9. Per Section , press the built-in switch on the
upper solenoid valve (B) and verify less than 10
seconds to lower. If not, then verify 80+ psi then
follow the pneumatic calibration instructions.
10. Per Figure 8.5.1, verify continuity through the 2
pins of the Reed Switch 1 Deutsch plug.
11. Per Figure 8.5.1, with switch in DOWN position,
verify no continuity from terminal 85 to ground, then
verify 9 to 15 volts from ground to the following 3
terminals on Relay 1: 30, 86, and 87a (NC). Next,
verify 9 to 15 volts at DOWN solenoid connection of
direction control valve by removing the Phillips head
screw from the connector and sliding it off the
control valve.
