Procedure
Before stall testing the isolation fluid pump, be sure
that air and fluid are supplied to the system.
Prime the system to make sure that there is no air in
the pump. Put the system into Standby mode.
1.
Press the Fill button. The system automatically
fills.
Be sure the gun trigger is released. During the
test, the fluid line pressurizes to the active preset
value.
2.
Press the Stall Test button. The isolation fluid
pump pressurizes and the system monitors the
linear sensor to look for leaks with the pump at
the top of the pump stroke. The screen displays
the text, "Stall Test" and "Test In Progress."
The test takes about 1 minute to complete. If the
test is successful, a confirmation displays on the
screen. The system returns to Standby.
3.
Press the Spray button. Dispense between
700-1000 cc so that the pump is about 1/4 full.
4.
Be sure the gun trigger is released and press the
Stall Test button. The system is now tested with
the pump near the bottom of the pump stroke.
The test takes about 1 minute to complete. If the
test is successful, a confirmation displays on the
screen. The system returns to Standby.
Note
In addition to the HydroShield, this test
checks the hose connections and gun. If the
test fails, repeat the test with the ball valve
on the inlet to the fluid pressure regulator in
the closed position. The test will only check
the isolation fluid pump and connections
inside the HydroShield.
