Filtration Group MFS-E900 Traduction Du Mode D'emploi Original page 41

15 Normal operation
 The E900 works automatically during normal operation.
Conditions for trouble-free operation:
 The external release signal must be enabled whenever
fluid is pumped through the filter.
 If the system is susceptible to failure in case of pressure
loss, the release signal must be enabled each time the
workpiece is changed, for example.
 One cleaning cycle takes approximately 10 s in normal
operation.
 In systems with external pressure cleaning by means of
compressed air, remember that this air must be supplied
separately.
