3.3 Control Unit installation
Due to the PM230 having either a cover to remove or a door to be opened to access the
actual PM the fitting of the CU and the removal of the CU slightly differs; the complete fitting
and removal instructions are given below.
Fitting and removing the CU to the PM230 FSA to FSC
To fit the CU to the PM230 FSA to FSC the following procedure should be performed:
1. Remove the PM top cover by unscrewing the retaining screws of the cover (the screws
are self-retaining and cannot be fully removed from the cover).
2. Fit the CU to the PM as previously described above.
3. All wiring of the CU and PM should be completed before proceeding further (refer to the
wiring/connection section of this manual).
4. Ensure that the D-type adaptor is fitted to the CU D-type connector. See figures below.
5. Replace the PM cover, ensuring that all seals are intact to maintain the IP55 rating.
6. If an Operator Panel/Blanking Panel is to be fitted, ensure it is fitted once the top cover is
replaced.
7. Tighten the retaining screws on the PM top cover (tightening torque 1.5 Nm [13.3 lbf.in]).
