2. CHEKING MOTOR MOVEMENTS.
IMPORTANT!!! While operating C1A or C1B care must be taken to insure that the metal disc
WILL NOT cross the limit sensors boundaries.
2.1 Switch C1A /C1B momentarily with the manual lever. (Mounted at the center of C1A / C1B)
Verify that C1A turn on the motor to IN position and C1B turn on the motor to OUT position.
IF not Switch MAIN switch to OFF (0) position , and exchange wires between two of the motor
phases. (Between TB6 & TB7 or TB7 & TB8).
Switch the MAIN switch to ON (I) and check again for correct movement.
2.2 Check limit switch LSI by holding C1A manually until metal disc reaches LSI sense
area and check that it's build-in LED illuminates.
- Check that PLC INPUT indicator no. X4 also lit.
2.3 Check limit switch LSO by holding C1B manually until metal disc reaches LSO sense area and
check that it's build-in LED illuminates.
- Check that PLC INPUT indicator no. X5 also lit.
In case of reverse LSI/LSO signals exchange between LSI/LSO signal wires between TB17 &
TB18 in the filter connection box.
2.4 In this state you can leave the motor at LSI or LSO position.
2.5 Switch on (up) circuit breaker marked F2.
3. SCAN TIME REGISTRATION. (Factory set while testing the filter.)
In order to register the IN / OUT time of the motor movement in the PLC execute the following :
3.1 Verify that the metal disc ,mounted on the motor slug , is in LSI or LSO
Position and it's build-in LED illuminates.
3.2 Press the FAULT sw. until the motor activation. (For 5 sec.)
The motor is activated for two scans.
Note that if it started from LSI position it will be activated from IN to OUT and
from OUT to IN. If it started from LSO position it will be activated from OUT to
IN and from IN to OUT.
Now the IN and OUT scan time is registered in the PLC and will be used by the PLC mechanism
as a referenced time in case of LSI/LSO malfunction.
The system is ready to operate.
