4.2 START-UP
Switch on the power supply to the Apex Transmitter Unit.
With a correctly installed Certified Sensor the following information is shown sequentially on the
LCD screen:
4. OPERATION
CONNECTING
INITIALISING
CO
100 ppm
HONEYWELL
ANALYTICS
0
The Transmitter Unit initially waits for the Certified Sensor to stabilise, during which period the
4-20mA output is inhibited (2mA). Wait for
15 minutes
to ensure sensor stabilisation has occurred
before continuing.
If the sensor does not stabilise during the initialisation period (
15 minutes
), one of the fault (
F
) or
warning (
W
) alarm messages shown in Section
4.6
is displayed.
When the Certified Sensor stabilises, the LCD screen shows the current
Gas Reading
together with
the gas identity, full scale, and the units of measurement.”
Note: If the current Gas Reading exceeds full scale the displayed reading will be replaced with
’ >>>>’.”
This information is also transmitted on the 4-20mA output and optionally on the digital network if a
communications board is fitted in the Transmitter Unit.
Note: If the Transmitter Unit has a LonWorks Communications Board fitted then the unit will, at
some stage, need to be bound to the LonWorks network. To do this carry out the LonWorks
binding procedure described at the end of this chapter.
