Error Code Meaning
The reset of a latched signal overrange
fault condition should only be carried out
after checking that the sensor is in clean
(non target gas) air.
Card In Wrong Slot
The card in wrong slot message is
displayed if a channel card has been
moved to a different slot from the one
that it had been calibrated for.
This allows cards to be moved to
alternative slot locations for fault finding
purposes. This message may also be
displayed when fitting a new channel card
or fitting a spare replacement. The
message can be cleared by calibrating
the channel card to the new slot location
and connected sensor.
Depending on the alarm configuration,
moving channel cards to alternative slots
may compromise the generation of
alarms. The alarm operation should be
checked after the card has been moved
and calibrated.
Power Fail Error
The power fail error message is displayed
if the system supply voltage falls below
approximately 16V dc. The error latches
if power failure delay is not enabled.
Check the operation of the power supply.
When the power is correctly restored,
check operation of system.
Datasum Changed
The datasum changed message is
displayed if there is a failure in the channel
card RAM during normal operation.
The card should be reset by removing
the power to the card. This is achieved
by removing the card from the rack slot
and then replacing the card back into the
rack slot. If the error message persists
the card needs replacing.
