•
cannot touch the motor. Caution: Depending on the drive type the motor can warm up and
get hot - what is not a malfunction!
•
Wire clamping arrangement in the upper part of the installation casing
•
Screw union nut of the screwed cable gland. Caution: A high IP-Protection class is only
achieved in this way.
•
Select the desired mode of operation by placing the jumper at the corresponding pin couple
•
Place device on installation casing and push onto it. When doing this take care that no cables or
stranded conductors are squeezed.
•
Fasten device with the four casing screws at the installation casing. Caution: Turn screws only
till the gasket is pressed. If the screws are turned too wide, the plastic thread in the instal-
lation casing is twisted off!
•
Remove cover of the pump case by pulling off in the lower region
•
Attach feeding tube on the left and output tube on the right side of the tube retainer.
•
Fasten tubes with tube clips respectively threaded joints
•
If required replace stopper in the middle of the tube retainer by the drain-off-connection piece
and attach additional tube which drains the pump case back into the packaging drum of the prod-
uct in case of a damage of the pump tube
•
Attach cover of the pump case and press until it catches
•
Remove cover of electronic and make adjustments (see "Mode of operation"). Put in cover of
electronic again.
•
Place front hood and press till it catches
Important: Examine if there are any measures to be carried out that are described in the safety
regulations of the delivery product. If so, carry out the necessary measures.
Setting the mode of operation
The desired mode of operation is selected with a
jumper (small electrical bridge) on the electronic
circuit board by simply putting it on the corre-
sponding pin couple. Default setting of the device is
mode of operation 2 (shown in the figure on the
right side). If another mode of operation is neces-
sary, pull jumper upwards with a forceps and put it
onto the pin couple that corresponds to the desired
mode of operation.
Mode of operation 1:
adjustable rate of delivery
With mode of operation 1 the revolutions of the rotor of the pump can be adjusted to a fixed value.
With potentiometer P1 the speed is adjusted coarsely, with potentiometer P2 the adjusted value can
be corrected finely.
• Set jumper on printed circuit board to position 1
• Put neutral conductor to terminal 1 and phase / mains to terminal 2

• With potentiometer P1 the speed of the rotor (revolutions) and about that the rate of delivery can
be adjusted coarsely. With potentiometer P2 the adjusted value can be corrected finely (about
10% of the range of P1). If the control voltage at terminal 3 ("In1") is active, the pump pumps
with the rate of delivery corresponding the settings of P1 and P2.
• On terminal 11 and 12 a suction pipe with float switch for package-drum-empty-detection can be
installed. If a package-drum-empty is detected, the signal LED L3 blinks and an external voltage at
terminal 6 is switched from terminal 7 to terminal 5 for example to drive an external optical (SWB
8009) or acoustical warning signal.
• If no suction pipe with float switch is installed, terminals 11 and 12 must be bridged!
• With the galvanic shutter on terminal 13 and 14 closed, the pump delivers corresponding the
adjusted values with P1 and P2.
Mode of Operation 2:
Controlling the rotor speed by current signal 4..20 mA (increasing ro-
tor speed with rising current)
• Set jumper on printed circuit board to position 2 (if not default ). With the jumper in position 2
the rotor speed increases with a rising current signal.
• Put neutral conductor to terminal 1 and phase / mains to terminal 2.
•
Put current signal (-) to terminal 9 and current signal (+) to terminal 10.
