7 Maintenance Procedures
This chapter describes how to perform common maintenance operations.
The required frequency of inspection and maintenance will depend on local site conditions and will need to be established
through experience. Please refer to the following standards or other local or national regulations for guidance on establishing
an appropriate maintenance routine:
EN 45544-4
contains information on the use and maintenance of electrical apparatus used for the direct detection and direct
concentration measurement of
toxic gases and vapours.
Note
: When finished, ensure that all enclosures are closed and locked, and ensure that the maintenance and rectification is
recorded.
7.1
Routine Maintenance
Routinely (i.e. daily, weekly or monthly depending on local conditions) carry out the following tasks:
•
Clean the Touchscreen with a soft cloth and mild detergent, or use a proprietary VDU screen cleaner.
•
Check the screen for correct operation
•
Remove dust and other contamination (particularly on rack mounted units or enclosure vents).
•
Periodically exercise the relays to confirm functionality (see
Ch.16 How to Test the TPPR System
).
•
Check that the SD Card still has free space.
•
Check the condition of the enclosure for security, corrosion, deterioration of door seals, blocked ventilation, loose
fixings and other damage that could impair the safety and operation of the equipment or its safety function.
WARNING
If the relays are switching mains voltages, hazardous live terminals may be present within the Relay Output Module
even if the Touchpoint Pro system is isolated.
WARNING
To avoid any unwanted activation of output devices (e.g. emergency flooding) always inhibit or disable relay
activated outputs before exercising the relays and remember to enable them when testing is finished.
CAUTION
Do not use solvents or abrasives to clean any part of the TPPR as this may cause irreparable damage.
WARNING
Maintenance procedures should only be carried out by Honeywell authorised persons or qualified persons trained in
accordance with the
Touchpoint Pro Technical Handbook
as errors can adversely affect system functions.
