Concept 420 i
Peristaltic pump "Concept 420 i"
The peristaltic pump "Concept 420 i" is a high-quality dosage pump for the dosage of liquid prod-
ucts with a micropocessor-based closed-loop revolution controller which can be controlled by a
current signal 4..20 mA.
Basic equipment / features
•
self-priming peristaltic pump with spring-loaded rotor and with a pump-head with snap-in cover
for a quick and easy changing of the pump tube
•
Controlling of the number of revolutions by a current pump-head 4..20 mA, stopping of the
pump by a current signal smaller 4 mA (mode of operation 2, factory-setting).
•
genuine closed-loop revolution control (GCL-technology): rotor speed stays exactly on the
adjusted value independent from material and state of the pump tube, viscosity, suction height
and independent from fluctuations of ambient temperature and operating voltage within the
specified ranges
•
twin ball bearing gear ensures high lifetime of the device
•
high-speed-button for filling the assembled tubes
•
package-drum-empty detection when using suction pipes of the type SLNS 9608
•
detection of a broken pump tube, when using media, that are electrical conductive
•
compact casing, easy to install
•
mode of operation 1: adjustable rate of delivery with 2 potentiometers (P1 coarse and P2 fine)
•
mode of operation 2: adjustable rotor speed by a current signal 4..20 mA, corresponding to the
potentiometers P1 and P2. Rotor speed rising with increasing current signal.
•
mode of operation 3: adjustable rotor speed by a current signal 4..20 mA, corresponding to the
potentiometers P1 and P2. Rotor speed falling with decreasing current signal.

Mode of operation 3:
Controlling the rotor speed by current signal 4..20 mA (decreasing
rotor speed with rising current)
• Set jumper on printed circuit board to position 3 (default is position 2). With the jumper in posi-
tion 2 the rotor speed decreases with a rising current signal.
• Put neutral conductor to terminal 1 and phase / mains (230 V) to terminal 2
• Put current signal (-) to terminal 9 and current signal (+) to terminal 10. The range of the rate of
delivery can be varied by potentiometers P1 and P2.
• With potentiometer P1 the rotor speed for a current signal of 20 mA is set.
• With potentiometer P2 the rotor speed for a current signal of 4 mA is set
• The rotor speed (rate of delivery) results form a beam between the two operational points which
are set with potentiometers P1 and P2 at 4 mA and at 20 mA. With this feature it is possible to
adapt the pump to different working conditions and a desired behaviour of the controlling is
achieved.
• With a current signal 20 mA the drive of the pump is stopped.
• 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 stay bridged!
