When fault finding, carry out the following steps as far as is necessary.

• Check that, at least, one of the carrier power LEDs is ON.

• If a power LED is not on, first check the incoming supply is present and then check

the on-board 2.5A (T) fuse(s) and replace blown ones, after identifying the cause

of the fuse rupture. (Spare fuse kit FUS2.5ATE5 Pk 10)

• Check that all UI modules are displaying a green Status LED.

• A flashing LED indicates alarm or fault conditions - refer to section 8. Note: The

LED may also flash during intermediate stages of configuration.

• Exchange a potentially faulty UI module for a working unit

(see Section 5.2.2 for method).

Note that a replacement UI will automatically acquire the configuration from the

module base.

7.2

Check the general condition of the installation occasionally to make sure that no

deterioration has occurred. Carry out the following at least once every two years and

more frequently for particularly harsh environments.

a) Check the module LEDs to ensure that no ERROR conditions are being indicated..

b) Check to see that all UI modules do not appear to have been disturbed and appear

to be seated correctly in their module bases.

c) Check to see that any surge suppression modules fitted are correctly seated and

the tag strips are locked in place.

d) Check that modules and hazardous-area connections are correctly and legibly

tagged, and that the tag details given comply with the relevant documentation.
