CLEANING AFTER OPERATION
It is possible to choose cleaning after operation, that is when the fan
has stopped. This is more efficient than cleaning during operation
and is therefore recommended. The pause time at cleaning after
operation is always 15 s.
In cleaning after operation has been chosen, one has to set the desired
number of cleaning cycles (S 2), where one cycle means the cleaning of
the total number of filter cartridges, that is 6, 12 or 18 cartridges, depen-
ding on the number of modules in operation. 2 - 3 cycles are recommen-
ded depending on the dust load (light - normal) When cleaning after
operation it is recommended to use an after cleaning damper (see
accessories page 32).

REMOTE START
It is possible to choose the following functions for Remote start
by setting S3. For most filters that are remotly started from a
machine or a process eg. it is convenient to set the Remote
start switch S3 to 2 ON.
2 OFF When using remote start there is no automatic
restart when the fault has been rectified.
2 ON When using remote start there is automatic restart when
the fault has been rectified or after a power failure
(is recommended).
The remote start control should be connected to JP 1 and 9 or 10
(see page 10). If remote start is used, the system can not be stopped
with the 0/1-button on the Control Box.
