5.4 - Electrical installation
Technical electrical specifications:
●
Reduction motor, see chapter 2 (Technical Specification). The electralmotor needs to installed with a current
overload protection acc. to EN 60204-1.
●
Dp-switch: SPST 25W max 0,5 A + max. 240 VAC/VDC.
●
Solenoid(s): 24 VAC-D 50/60 Hz 2,2W
Filter control:
●
Flush modes:
�
Automatic (triggered by pressure difference and by time)
�
Manual
Automatic flush mode
●
The flushing of the filter will be initated by de DP-switch (
∆P > 0.5 Bar)
●
After approx. 10 seconds a flushing cycle needs to be started (Pre-Dwell time)
●
If applicable, first close the mainvalve installed after the filter. The flushing cycle may start if the mainvalve is
fully closed. The time needed for the closure is depending on the type of valve installed.
●
The flush cycle will be started when both the eletrical motor and the solenoid on the flushing valve are
activated. A flushing cycle needs to be at least 30 seconds. After this time the electrical motor and the solenoid
valve need to be decativated.
●
If more than one filter is installed the pressure difference over all installed filters need to be monitored by means
of one DP-switch. The DP switch need to be installed into the combined in- and outlet line.
●
If multiple filters are installed the flushing needs to be preformed one after another. Between the changeover of
the filters a dwell time of 5-10 seconds needs to be taken into account.
●
In case an electric valve is installed on the auxilairy filter, we recommend to activate this electrical valve every
30 flushing cycles for approximatly 5-10 seconds.
The flushing of the auxilairy filter may never be done during a regular flushing cycle of the 6Matic filter.
