MAINTENANCE
IV.1 FORMALISATION
To follow maintenance procedures correctly, the following points must be observed:
▪ Create a maintenance file containing the headings “Date”, “Time”, “Maintenance Engineer”, “CCR
reference”, “Problem definition”, “Solution applied”, and “Time spent”
▪
The spare parts monitoring sheet (with their control numbers) should be completed if necessary.
▪
An overall maintenance operation book or folder for each maintenance post will be kept up to date
with these sheets. It will gather together, in particular, all the device test reports and references to
the initial states of the devices.
▪
A regular examination of these different documents will allow the status of the system to be
monitored, facilitate management of spare part batches and improve, if necessary, maintenance
procedures.
IV.2 PREVENTIVE
IV.2.1 FIRST MONTHS
In the first months of use, check the tightness of terminals and connections, particularly for HV or LV power
circuits :
▪
Input terminals, fuse-holders, contactor
▪
Output terminals, all screwed connections.
IV.2.2 ANNUAL PROCEDURE
▪
Remove dust from the bottoms of the casings to avoid accumulation, which could prevent proper
cooling.
▪
Remove dust from the electronic circuit boards and LV elements.
▪
Check the tightness of power connections (Lighting loop, Power, Earth)
▪
Check operative functions, in local and remote control.
IV.2.3 EVERY THREE YEARS
The frequency with which these operations are carried out will depend on the usage of the CCR:
▪
Start by a general visual inspection
▪
Check internal connections (tightness of screws and terminals),
▪
Check the correct correspondence between: current setting, displayed value, measured value (use
an insulated true RMS ammeter and clamp of sufficient accuracy)
In case of discordance, a calibration of the CCR can be carried out.
