ACF5000 FTIR ANALYZER SYSTEM | OI/ACF5000-EN REV. A 161
Replacing wearing parts
Before executing maintenance work on the analyzer system, the mainte-
nance control must be activated in the control display in order to set the
maintenance mode status signal.
Furthermore, the gas flow control in the control display must either be set to
zero gas local (zero air inlet directly on the measuring cell) or zero gas probe
(zero air inlet via probe) in order to avoid any contact with the measuring
gas.
After completing the maintenance work, the maintenance control and the
gas flow control must be reset.
For work on hot device parts, the temperature may drop and lead to a tem-
perature error of the system and, where applicable, to the activation of
emergency purging.
After completing the maintenance work, it must be waited until the temper-
ature error is no longer active; where applicable, emergency purging needs
to be deactivated.
