Chapter 6. Routine Maintenance and Scheduled Testing
This chapter describes how to perform common maintenance operations and system testing. The required frequency of
inspection and maintenance will depend on local site conditions and will need to be established through experience.
Please refer to IEC/EN 60079-29-2 or other local or national regulations for guidance on establishing an appropriate
maintenance routine.
6.1 Routine Maintenance
6.1.1 Weekly Checks
• Visually inspect all cables and conduits for loose connections, security of attachment, and signs of damage.
• Wipe the Touchpoint Plus Controller with a soft damp cloth or use PC Screen cleaner.
• Check for dust contamination.
• Periodically exercise the outputs (see the following chapters) to confirm their functionality (see Caution above).
WARNING
If the relays are switching mains voltages, hazardous live terminals may be present within the
Relay Output Module even if the Touchpoint Plus system is isolated.
Ensure that all current is isolated and dissipated before touching live terminals.
WARNING
Read Chapter 2 Safety and other related warnings and cautions before carrying out any work on the system.
CAUTION
Test outputs will be generated and relays will be activated during Cause and Effect (C&E) Testing.
Ensure that relay activated output systems (i.e. emergency deluge / sirens etc.) are isolated before starting the
Relay and mA Output tests.
CAUTION
While an Operator could Force a channel, a Service password is required to isolate services, carry out tests,
Clear Force, and restore the system to full operational status.
For these reasons Operators should carry out visual inspections and cleaning only, unless under the direct
supervision of the Service engineer.
CAUTION
Do not use solvent or abrasives to clean any part of the Touchpoint Plus System.
Use only soft, lightly dampened cloths or proprietary screen cleaners.
