Configuring the purge air heater
The operating behavior can be configured in SOPAS ET. It is only possible to switch between
“Deactive”, continuous operation (fixed value during blower on) and operation only during
the control cycle (fixed value during purging).
Selection is made using the “Heater settings” menu in SOPAS ET. The default setting is con-
tinuous operation and connection to Heater4.
Fig. 16: Heater settings in SOPAS ET
The purge air temperature is controlled directly on the purge air heater. The factory setting
of the purge air temperature is configured to 90 °C. The red regulator is locked in this
position with a seal sticker. The purge air temperature can therefore only be modified by
destroying the seal sticker, but this should only be done with great care. Protection against
unintentional adjustment of the regulator must then be replaced.
CAUTION:
The maximum temperature should not exceed 120 °C, otherwise damage to the system
and purge air hoses is to be expected.
NOTE:
The purge air temperature should only be changed under compliance with all relevant
safety instructions and knowledge of potential dangers. If the purge air temperature on
the purge air heater is changed, protection against unintentional adjustment of the
controller must be provided again.
