4.2.2 Pre-Start-up Electrical Checkout
After the preliminary procedures have been accomplished (refer to Prelimi-
nary Inspection and Control Settings, above), the integrity of the system inter-
connection and the power sources must be verified before attempting the analyti-
cal start-up procedures.
The observations and measurements described in the following paragraphs
are vital to the operation of the analyzer. If the analyzer does not respond as
described, the equipment has been damaged in shipment or installation, or the
user-installed wiring is in error. If a problem arises, correct it before proceeding
further.
The following procedures should be employed in the same sequence in
which they appear.
4.2.3 Power On Observations
Turn both the analysis/control module at the remote wiring panel of
customer to ON and make the following observations:
1. Open the control/analysis section detector module and verify that
the chopper motor is operating. Open the cover of the
compartment and verify motion. The motor should start turning
the instant power is established. If it does not, check the integrity
of the main fuse on the control module door. If the fuse is blown,
re-check the power service connections on TS2 in the control
module, and the control module to analysis section
interconnection wiring (refer to Electrical Installation in Chapter
3.0: Installation, and dwg. _________).
2. The lamp source should light the instant power is established.
Open the enclosure door and view the source module to verify
illumination.
WARNING: 1. The light intensity from the Mini IR lamp or quartz iodine lamp
If used is intense and should not be looked at directly without
special protective eyewear. Protective goggles with shaded
lenses (Fed. Spec. #5) should be worn if it is necessary to look
directly at the source.
2. Before opening any of the enclosure covers with the power on,
make certain that the area has been classified as safe to do so.
