V 06/13
If malfunctions take place, the signal horn sounds and an alarm message
is shown (see the chapter "Troubleshooting" and the control unit user
manual).
The filter cartridges in the After Filter are blown off cyclically from the
inside during operation. The predetermined cycle times are set at the
factory, but must be reset if the maximum differential pressure is
repeatedly exceeded (this initiates an alarm).
The differential pressure is displayed on the pressure gauge:
Pressure monitoring on the filter - is only displayed optically
-
on the pressure gauge
Pressure monitoring on the fan - is displayed optically and
-
the alarm is initiated by 2 manostats (optically and
acoustically)
The upper limiting value, by which the alarm is initiated, is plant-specific
and is set by our trained service personnel when assembling the booth.
The setting of the cycle times must be done only by trained service
personnel. The input is entered directly on the operating unit of the plant
control (see also the operating manual of the plant control unit).
The color change can begin, when the last workpieces have left the
booth. In automatic operation mode, the coating is stopped automatically.
Following, a step by step description of the color change procedure from
bright to dark (or vice versa) is given. A prerequisite for a quick and
efficient color change is that it is done by 2 people, so that some of these
steps can be carried out simultaneously.
