Sub PCBs and CONFIGURE GASES
The CONFIGURE GASES menu item in Setup Mode allows you to configure the gas for
a catalytic, TC, or PID sensor that is installed. There are four possible sensors that can be
configured depending on the particular version of the EAGLE 2. The LCD screen below
illustrates the first screen in the CONFIGURE GASES menu item in Setup Mode.
The four possible sensors are a catalytic sensor and three optional sensors. They are listed
with the following information from left to right:
•
The circuitry that supports the sensor and whether it is standard or optional
This can be the catalytic circuit on the main PCB indicated by CAT or one of the
sub PCBs indicated by OP1 (option 1), OP2 (option 2), and OP3 (option 3). OP1
indicates that the SUB1 PCB supports the sensor, OP2 indicates that the SUB2
PCB supports the sensor, and OP3 indicates that the SUB3 PCB supports the
sensor. The OP1, OP2, and OP3 identifiers also indicate that the sensor is an
optional sensor. The catalytic sensor is a standard sensor. Each of these is always
listed.
•
The currently configured gas
The catalytic sensor is always defined and configured even if it is not setup as
active in CONFIGURE CHANNELS. If any of the Sub PCBs are not installed,
then the corresponding sensor is undefined and the next two fields are filled with
dashes (---). In the example above, the catalytic sensor is configured as methane
(CH
4
), the sensor supported by the SUB1 PCB is configured as isobutylene
(IBL), the sensor supported by the SUB2 PCB is configured as ammonia (NH
3
),
and there is no sub PCB installed in position SUB3.
