Service, Maintenance & Disposal
7.1 Equipment Service
The Controller requires no internal servicing during its normal operating lifetime. A number of external system based
checks should however be made on a regular basis. These ‘routine inspections’ must be carried out by suitably
trained people with knowledge of the Controller and the systems into which it is fitted.
Routine inspections may take the form of either simple visual-only checks, or visual and ‘hands-on’ checks.
7.1.1 Visual Only Inspections
A basic visual inspection will focus on looking at the installation for signs of physical damage, water or dust ingress
as well as the condition of cables and labels. This type of inspection may involve opening cabinets to gain access to
the Controller and other equipment. This level of inspection may also include cleaning display windows that have
become obscured by dirt.
NOTE: The Controller’s enclosure and display window must only be cleaned using anti-
static cleaning materials. Do not clean the Controller with any cleaning products that may
cause the build-up of static charge.
Observations would typically be:
• Check that equipment enclosures, cable trays, conduits, wall-boxes etc. are in good order with no physical
damage
• Check that sealed wall-boxes are free from water and dust ingress internally. Door seals are in good
condition.
•
Check that connected cables are free from cuts, abrasions and obvious signs of damage. Cable restraints
are in good order and correctly fitted.
•
Check that labels on equipment, wall boxes and cables are present and in good clean condition (especially
certification labels)
•
Check that no modifications have been carried out to installed equipment.
7.1.2 Hand-On (Detailed) Inspections
A more detailed inspection would include all of the elements of a visual inspection, plus some checks that cover the
integrity of connections, fixtures and fittings.
In addition to basic visual observations, more detailed integrity checks would involve:
•
Verify that equipment housings, wall boxes and other mechanical fixtures are secured tightly in place. This
includes the lids of terminal boxes, tightness of cable glands, integrity of wall-box mountings, security of
equipment fixing to walls / DIN rails etc.
• Verify all electrical connections are secure with no loose screw terminals or DIN rail terminals not fitted to
rails etc.
