This will lock the software controlling the Rosemount CT5100(Ex) requiring the analyzer to
be shutdown externally and restarted risking a possible corruption of the software and loss
of the analyzer operation during the shutdown and restart process.
It is essential that only trained, qualified personnel operate the controls on the analyzer.
Failure to follow these instructions may cause warranty invalidation, property damage
and/or personal injury or death.
The purge control panel ( Figure 4-8 ) is used to program the operation of the overpressure
air system that prevents flammable and explosive gases from entering the electrical
compartment of the Rosemount CT5100(Ex). Adjustment of the overpressure air system
must only be performed by maintenance personnel.
Five LEDs, identified as K1, K2, PSV, Bypass and PT100 are located on the upper part of the
purge control panel. These five LEDs indicate the status of the overpressure air system.
