7.5 Input Y2
Function - Start cleaning
[Cleaning / Input Y2]
Y2 on (swipe signal): The addition time is set to 0, cleaning takes place at the next possible time
Function - 1,100[%] (volume flow)
[Cleaning / Input Y2]
Y2 on: Cleaning is suppressed or aborted. The set volume flow is counted towards the addition time. This
makes it possible to connect an additional extraction unit to the filter.
7.6 Relays K3 and K4
Various functions can be programmed on the relays K3 and K4. It is also possible to program several
functions on one relay.
Function - Volume flow >>
[Relay / volume flow >>]
"Volume flow exceeded" message on relay K3, K4 or off
Function - Discharge
[Relay / Discharge]
Control of a "discharge" on relay K3, K4 or off
Function - End position error
[Relay / End position error]
Message of end position errors of the sliders/flaps on relays K3, K4 or off
7.7 Analog output
Proportional to the volume flow, a voltage is output at the analogue output.
This can control a frequency converter on an extraction motor.
Output voltage (DC 0.10 V) at 0% volume flow
[Analog output / U at 0% volume]
Volume flow at DC 10 V output voltage
[Analog output / 10V at volume]
When the extraction is switched off (relay K2 off), the output voltage is always 0V.

Important Information
DANGER!
Hazardous voltage!
Will cause death or serious injury. Turn off and lock out all power
supplying this device before working on this device.
WARNING!
The control voltage must have suitable insulation that complies with SELV (Safety
Extra Low Voltage) conditions.
All connections (except relay contacts) and Ethernet have no mutual potential
separation/isolation. When connecting a device to the analogue output
(OUT O+, O-), it must have reinforced insulation / safe isolation from the load/mains
side.
Attention!
When using current transformers STWA1 or STWA1H for current measurement, the
following must be observed: Only one current-carrying conductor may be passed
through the current transformer.
