Start-up and first operation
1.
Make sure all the electric wiring is correct, according to the enclosed drawings.
2.
Turn on control power and 24VAC but leave OL protector off. Verify that the limit switches are wired correctly by manually
toggling them. Monitor the appropriate inputs according to the wiring diagram accompanying the control panel. Proceed to
next step only after verifying correct wiring of all limit switches in the system.
3.
CHECK ROTATION:
The suction scanner shaft should turn clockwise (CW) and move towards the filter housing until it reaches
limit switch "A". If the motor rotates in the opposite direction (CCW),
turn off the electricity immediately
and change the
direction of the motor rotation by changing between two phases.
4.
The motor must stop when the limit switch plate reaches limit switch "A" (opening the NC circuit).
5.
Operate a "dry" flushing cycle by pressing on the "TEST" push button. Check that the flushing cycle runs as described in the
“Self
-
cleaning process”
paragraph in this manual.
6.
Open the inlet valve to the filter, leaving the outlet valve closed or with an open by-pass valve (This will keep the flow through
the filter to a minimum), and operate a flushing cycle.
7.
Check that the exhaust valve opens and all stages of the flushing cycle perform properly. Attend to leakage, if any.
8.
Close the 1/4" valve at the low pressure sensing port of the pressure differential switch for 5 seconds. The PDS hand will move
to the red area and the filter will start the flushing process.
Re-open
the 1/4" valve.
9.
Gradually open the outlet valve and/or close the by-pass valve. Operate the filter under the designed hydraulic conditions.
10. Set the flushing interval timer (T1) for 6-8 hours.
11. Check and re-tighten all bolts after the first week of operation.
* When using Control board type "C" (Relay type) it is necessary to press the "Test" push button in order to start the motor operation
for the first time.
