Maintaining the MCUP for use zone 2
The relays in the optional relay modules must be inspected periodically. We recommend to
begin with short periods of time and to extend depending on the influence strength and the
inspection results.
To check the relays, open the enclosures of the modules carefully.
Suggestions of degradation can be:
●
Discoloration
●
Deformation
●
Perforation
●
Malfunction
●
Overheating
●
Other remarkable changes
In the event of any degradation of properties these parts must be replaced by the original
type. Replacement by complete processor boards or complete modules is recommended.
To prevent repetitive degradation the user shall clarify the causes and shall take
appropriate precautionary measures before restart the equipment.
