7 Pneumac lter cleaning valve
7.1 Filter cleaning buon
The lter cleaning buon will only work when the system is in Standby mode or Running
mode.
7.2 Filter cleaning in Standby mode
Perform a lter cleaning in Standby mode as follows:
1. From O mode, put the unit into Standby mode by pressing the Standby/Running
buon.
2. Start lter cleaning by pressing the lter cleaning buon.
The unit goes into Running mode, the motor starts and the FCV closes and vacuum is
established in the system. The unit will now open and close the FCV once and then leave
the FCV in its open posion. Aer the cleaning cycle, the unit goes into Idling mode. The
unit waits for a pilot signal for 10 minutes. If the pilot signal is not received during this me,
the unit will stop its motor and go into Standby mode.
To perform a new lter cleaning in Idling mode, acvate the pilot signal and enter Running
mode, or toggle the Standby/Running buon to go to Standby mode and press the lter
cleaning buon again.
7.3 Filter cleaning in Running mode
Perform lter cleaning in Running mode as follows:
1. Put the system into Standby mode by pressing the Standby/Running buon.
2. Acvate the pilot signal by connecng terminals X1:13 and X1:14 with a jumper.
The unit goes into Running mode. The motor starts, the FCV closes and pressure is
established in the system.
3. Start the lter cleaning by pressing the lter cleaning buon.
The unit will now open and close the FCV 3 mes and then leave the FCV in its closed
posion. Aer the last cleaning cycle, the unit returns to Running mode and waits for the
pilot signal to stop. It is possible to perform mulple lter cleaning cycles in Running mode.
When the pilot signal stops, the unit runs for 10 seconds (DIR me) and then opens the FCV
and goes into idling mode. The unit waits for a pilot signal for 12 minutes. If the pilot signal
is not received during this me, the unit will stop the motor and go into Standby mode.
The idling me is set by the SSR mer and default is 12 minutes. DIR me is the delay aer
the pilot signal has stopped before opening the FCV. The default is 10 seconds.
7.4 Filter cleaning valve funcon
The PLC output DO3 is set and sends +24 V to the solenoid valve. The solenoid valve opens
the air ow to the pneumac piston, which moves the lid on top of the lter upwards
leng in air with atmospheric pressure to the lter top. This sudden opening of the lid on
the top lets in air with great speed which creates a sudden pressure rise above the lters.
The pressure increase blows air through the lter bags removing the dust from the lters.
When power to the solenoid valve disappears, the valve closes and evacuates the
pneumac piston. The lid falls down and closes the opening of the lter top.
