TRANSCEIVER AND RETRO REFLECTOR ASSEMBLY
6) Attach the Transceiver and Retro reflector to the air
plenum assembly by placing them on the hinge pins.
7) Close transceiver & retro and secure in place with
the two hold down latches.
8) The air-purge blowers should be powered up at this
time to prevent stack particulate from accumulating
in the nipple and air-purge housing.
Caution: If installed location has a positive pressure the air-purge
system must be used continuously during installation to prevent process gases from contaminating optical surfaces or over heating
instrument electronics. If the system is shut off for more than momentary interruptions, the instrument may be damaged. Failure to
provide continuous air-purge may void the warranty.
All wiring from the control unit to the transceiver should be completed at this time.
NOTE: THE AIR PLENUM ASSEMBLY FOR BOTH TRANSCEIVER AND RETRO MUST BE INSTALLED AS BELOW, I.E. THE PINS ON
THE LEFT SIDE POINTING UP!
