docking station manifold bank and the other set will be used for the second docking
station manifold bank. If your EAGLE 2s of the same sensor configuration have 2
special sensors (ie. PID, TC, IR, ESM-01), you will need to change the GAS 2
cylinder for both banks of docking stations when the PC Controller Program prompts
you to do so. Be sure that you also have 2 calibration cylinders for your second
special sensor. If you have an EAGLE 2 for which a 5-gas cylinder is available, for
example standard 4-gas plus SO
2
plus NH
3
or standard 4-gas plus high range PID
plus NH
3
, the calibration cylinder for the second special sensor, NH
3
in this case, can
be connected to the GAS 2 fitting and you will not need to change it if you are using
the 5-gas cylinder for GAS 1.
If you have 5 or less EAGLE 2s with one configuration (ie. standard 4 plus TC) and 5
or less EAGLE 2s with another configuration (ie. standard 4 plus NH
3
), it is
recommended that you place the first set of like instruments in the first docking
station manifold bank and put the second set of like EAGLE 2s in the second docking
station manifold bank. You will need two GAS 1 manifolds of 5 or less docking
stations each for this situation and you will need 2 GAS 1 calibration cylinders. Only
one GAS 2 manifold is required for this situation. You will need to change the GAS 2
cylinder that is connected to the GAS 2 manifold at least once depending on how
many special sensors are installed in the various connected EAGLE 2s but you will
only need 1 of each required GAS 2 cylinder. The PC Controller Program will prompt
you to change the GAS 2 cylinder as required. If you have an EAGLE 2 for which a 5-
gas cylinder is available, for example standard 4-gas plus SO
2
plus NH
3
or standard
4-gas plus high range PID plus NH
3
, be sure that the 5-gas cylinder is connected to
the appropriate GAS 1 manifold and that the cylinder for the second special sensor, in
this case NH
3
, is connected to the appropriate GAS 2 manifold. See “Appendix A:
Multiple Instrument Configurations” on page 185 for instructions to bump test and
calibrate multiple instruments with different configurations.
If you have 6-9 EAGLE 2s with one configuration (ie. standard 4 plus TC) and 1-4
EAGLE 2s with another configuration (ie. standard 4 plus NH
3
), place the 1-4 EAGLE
2s in the same bank and place the 6-9 EAGLE 2s in the remaining docking stations.
You will need 2 manifolds both for GAS 1 and for GAS 2. You will also need 2 of each
calibration cylinder for GAS 1 and for the special sensor(s) in the 6-9 EAGLE 2s. You
will only need one calibration cylinder for each special sensor(s) in the 1-4 EAGLE 2s.
If you have an EAGLE 2 for which a 5-gas cylinder is available, for example standard
4-gas plus SO
2
plus NH
3
or standard 4-gas plus high range PID plus NH
3
, be sure
that the cylinder(s) are connected to the appropriate GAS 1 manifold(s) and that the
calibration cylinder for the second special sensor (if installed) is connected to the
appropriate GAS 2 manifold(s). See “Appendix A: Multiple Instrument Configurations”
on page 185 for instructions to bump test and calibrate multiple instruments with
different configurations.
Before you begin bump testing or calibrating, be sure the correct GAS 1 and GAS 2
calibration cylinders are connected to the appropriate manifolds for your instrument
configurations.
NOTE: If your instrument(s) include one or more infrared sensors, see
“Appendix B: Bump Testing and Calibrating EAGLE 2s with IR
Sensors” on page 218 for a description of the GAS 1/GAS 2
assignments for this type of sensor.
