General Safety Instructions
Electrical connections
All electrical wiring should be laid in accordancewith the relevant EMC standards as well as
any nationally valid regulations (VDE 0100 in Germany). Measuring lines should be laid
separately from signal and power lines. The protective conductor terminal (inside the
instrument rack) must be connected to a protective earth conductor.
We recommend using twisted and screened measuring lines to prevent disturbances from
interference fields. The electrical connections should correspond to the connection / terminal
diagrams for the unit concerned.
Start-up
The following points should be checked prior to starting up the unit.
The supply voltage must match the voltage indicated on the name-plate. All covers
necessary for contact protection must be fitted.
If the unit is interconnected with other units and/or equipment, you should consider the
potential consequencesprior to switching it on and take appropriate precautions.
The protective conductor terminal inside the instrument rack must be conductively connected to
the protective earth conductor (class I units).
The unit is only allowed to be operated if installed.
Operation
The unit is ready to operate as soon as the power supply is switched on. It may require
approximately15 minutes settling time.
aWarning
Any interruption of the protective earth conductor inside the instrument rack could render the

aWarning !
If it can be assumed that safe operation is no longer possible, the unit must be removed from
service and steps taken to prevent it from being started up again inadvertently.
The unit must be installed in a position in which it is not exposed to vibrations.
Troubleshooting
Should troubleshooting be necessary, we recommend that you start by investigating possible
fault sources in optional equipment or leads (measuring lines, wiring, units connected
downstream). If the fault still cannot be localised after checking these sources, the unit should
normally be returned to the manufacturer.
Note
Please note that sensors connected to the fed transmitter (especially thermocouples) tend
to be earthed and/or have significantly reduced insulation resistance during operation. In
this case, they must not be earthed additionally.

FilterController HE 5722
General Description
1 General description
The HE 5722 filter controller is used to measure differential pressure and to pulse magnetic
valves of the kind encountered in industrial dust removing applications.
The use of an MB90F347 microprocessor facilitates flexible selection of functions and extensive
monitoring functionality.
●Visual indication:
The unit has a four-digit display for the differential pressure. This display shows either the
value measured with the pressure sensor or that measured via the current input. The
current valve appears on a two-digit display. States and errors are indicated by twelve
LEDs.
●Differential pressure measurement:
The differential pressure across the filter is measured by means of a pressure sensor
integrated in the unit. The standard measuring range is 0 to 100 mbar; other measuring
ranges are possible on request. The actual differential pressure is indicated on a four-
digit display with one decimal place.
●Valve actuation:
Up to 24 valves can be actuated. The valve current is monitored, which means
overcurrent or interruptions at the valve controller output can be detected. The following
valve control functions are freely selectable:
- Threshold-controlledcleaning
- Post-cleaning of the complete filter
- Time-controlledforced cleaning
- Cleaning with separately settable control times
- Multiple pulse actuation of a valve
- Interval time proportional to differential pressure
●Inputs:
The filter controller has four electrically isolated inputs via which the “Stop”, “Rapid
cleaning”, “Post-cleaning” and “Acknowledge fault” commands are forwarded to the
microprocessor. The controller has a USB port for software updates. A standard signal (0
(4) to 20 mA) can be measured via an analogue input. The external signal and the internal
differential pressure signal can be used simultaneously. The stronger signal takes priority,
in other words a cleaning cycle can be started even if the programmed thresholds are not
yet exceeded.
●Outputs:
Three relays are provided for status, error and cleaning messages as well as special
functions ( cycle counter and lag time for discharge devices). These functions and the
FAILSAFE and HOLD switching modes are freely selectable.
The differential pressure is output via a non-isolated analogue output (0 (4) to 20 mA).
●Cleaning thresholds:
A high and low threshold can be set on the unit. Cleaning starts when the high threshold
is exceeded and ends when the low threshold is exceeded.
●Alarm thresholds:
You can program two alarm thresholds, which are indicated by means of LEDs.
The alarms can be assigned to the relays.
●Parameter protection:
The parameters can be protected with an access code.
