5.1
SECTION 5 FAULT DIAGNOSIS AND CELL MAINTENANCE
5.1 Introduction
A fault will be signalled wherever any parameter measured by the 2500's diagnostics
becomes out of tolerance. Any Fault condition will be indicated by the Fault LED on the
control panel being illuminated.
The Fault signal can be assigned to a Relay, as described in the Quickstart Manual.
Faults are categorised as either:
1. General Faults – parameter out of tolerance, intervention is required as
soon as possible. The analyser is still operational and measuring.
2. Serious Faults (Shutdown) – performance seriously degraded,
measurement withdrawn and analogue outputs driven HIGH (or low, as
configured in Section 3.2.2).
5.2 Diagnostics
The diagnostics listed in Table 5.1 can be interrogated via the DIAGNOSTICS function
in DISPLAY menu. See Quickstart Manual.
NOTE
For detailed instructions on all Service and Maintenance operations for suitably
skilled personnel, please refer to the 2500 Series Service Manual part number
