AirLink 7010 Gas Monitor Operator’s Manual
F8
There are 2 sensor assemblies with the
same address trying to communicate with
the monitor.
1. Make sure all sensor assemblies
have unique addresses.
F9
The monitor has not received a
communication from the faulting sensor
assembly address for the timeout period
set on page 36.
1. Check the sensor assembly for a
dead battery, broken antenna, bad
antenna cable, missing antenna,
obstacle, weather, etc.
F10
(4-20 mA
wired detector
only)
When using a monitor with wired sensor
assemblies attached, the sensor is not
communicating with the monitor. The
problem could be that the sensor assembly
is not connected properly, or there may be
board issues with the sensor or monitor.
1. Check all connections. Use a
current meter inline to see if the
current is correct.
F11
(battery
powered
detector only)
The IR sensor is changing temperature too
quickly.
1. The sensor will clear once the
temperature stops changing too
quickly.
F13
(4-20 mA
wired detector
only)
When using a monitor with a 4-20mA
wired connection, F13 may appear when
the sensor assembly is in a fault condition.
1. Since it is 4-20mA, the monitor
does not know the exact fault
condition. Therefore, check the
sensor assembly to see what the
fault is and then consult other
items in this chart for a solution.
