Error Code Meaning
Not applicable
High Integrity Relay Fault.
The actual and demanding states of the
high integrity relay outputs do not match.
Check that the high integrity relay card is
properly connected. If possible use another
known working high integrity relay or control
card to determine which card to replace.

Run Time Errors

Error Code Meaning
Hardware Fault
The hardware fault message is displayed if
the channel card detects a fault in its operation
or a fault with a sensor input.
Check the sensor connections. Remove the
channel card and insert it into a compatible
working channel and check its operation
(ER86 may appear during this operation - this
is normal). If the card still indicates a fault, it
must be replaced. If the card is working, the
sensor should be replaced.
Under Range Fault
The under range fault message is displayed
when the sensor signal reading is less than
the predetermined level held within the channel
configuration data.
Typically this is due to either the sensor or the
sensor cable installation being open circuit.
Over Range Fault
The over range fault message will appear
when the sensor signal reading is above the
predetermined level held within the channel
configuration data.
Typically this is due to either the sensor or the
sensor cable installation being short circuit.
Alternatively, the sensor may be detecting a
very high level of gas.
