2.
All electrical works at the installation site must be done by a qualified and authorized electrician only. Make sure that this
electrician is fully aware of all the relevant safety instructions.
3.
Install the control board in a dry and protected place (In out-door installation sites make sure to use a special control board for
out-door installation).
4.
Power connection to the control board:
a.
Connect a three-phase voltage source through a semi-automatic switch, or 16 Amp. fuse to the L1 L2 L3 inlet at the
terminal strip in the control board.
b.
Earth the control board.
5.
Power connection to the motor:
Connect the drive unit to the control panel by means of a 4 x 2.5 mm (12 or 14 AWG) wire in flex-conduct. Use a long enough
cable to allow the drive unit to be removed and placed near the filter for
maintenance, without having to
disconnect
it from the cable. (It is recommended that this installation meets or exceeds local or national electrical codes, this is a "high"
voltage connection).
6.
Control wiring:
The connection between the control junction box and the control board should be by 6 x 1.5 mm 2 (16 AWG) wire in flex-
conduct. The numbers on the terminals in the board and in the junction box are identical.
COMMISSIONING, START-UP AND FIRST OPERATION
1.
Before starting-up the filter read the safety instruction as appear at chapter 2 of this document and pay special attention to
the commissioning safety instructions.
2.
Inspect the filter’s installation and make sure that it is installed in accordance with the official installation drawings.
3.
Verify (by authorized electrician only) that the electric wiring is correct and complies with the enclosed drawings. Make sure
that the electrical start-up operation is done by an authorized electrician only.
4.
Switch ON the control & 24V circuit breakers. Leave the motor OL circuit breaker protector OFF.
5.
Toggle all limit switches to verify that they activate the correct inputs on the PLC according to the wiring schematic. Correct
connections, if necessary, before proceeding to the next step.
6.
Switch ON the motor protector circuit breaker The motor will start operating.
•
Control Board without Homing procedure: The suction scanner shaft should turn clockwise and move downward to
the filter housing until it reaches the lower limit switch. If the motor rotates in the opposite direction, disconnect
the electricity immediately and change the direction of the motor rotation by changing between two phases.
•
Control Board with Homing procedure: refer to the Homing section in the control boards operation manual.
The motor must stop when the limit switch plate reaches the lower limit switch and causes it to operate.
7.
Operate a "dry" flushing cycle by pressing on the "TEST" push button. Make sure all flushing stages occur as described in the
filter description chapter of this manual.
8.
Open the inlet valve to the filter, while the outlet valve remains closed or with an open by-pass valve (This will keep the flow
in the filter at a minimum), and operate a flushing cycle.
Make sure the exhaust valve opens and all stages of the flushing cycle are carried out. Attend to leakage, if any.
9.
Gradually open the outlet valve and/or close the by-pass valve. Operate the filter at the designed hydraulic conditions.
10.
Set the timer for 6-8 hours.
11.
Check and re-tighten all bolts after the first week of operation.
