Device
6.1
An electric motor drives a rotor. Rollers are fitted to the ends of the rotors,
which press the pump hose against the inner curvature of the dosing
head. The peristaltic pump operates by the rollers driving the feed chem‐
ical through the pump hose. The feed chemical is primed by the pump
hose automatically returning to its initial position.
6.2 Capacity
The capacity that has been set regulates the pump itself.
6.3 Operating modes
Operating modes are selected via the "Operating modes" menu.
"Manual" operating mode
"Contact" operating mode

CAUTION!
Material damage possible due to power surges
Should the pump be connected to the mains power
supply in parallel to inductive consumers (such as sole‐
noid valves, motors), inductive power surges can
damage the control when it is switched off.
– Provide the pump with its own contacts (Phase) and
supply with voltage via a contactor relay or relay.
Should this not be possible, then switch a varistor
–
(part no. 710912) or an RC gate (0.22 µF/220 Ω,
part no. 710802) in parallel.
CAUTION!
Bonding of the contacts of your switching relay
The high starting current can cause the contacts of the
on-site switching relay to bond together if the mains
voltage switches a solenoid metering pump on and off in
a process.
– Use the switching options offered by the external
socket to control the pump (functions: Pause, Auxil‐
iary frequency or Operating modes: Contact, Batch,
Analogue).
–
Use a starting current limiter if it is impossible to
avoid switching the pump on and off via a relay.

The secondary display "Signal current" indicates the incoming current.
You can select 5 types of current signal processing:
n
‘0 - 20 mA’
n
‘4 - 20 mA’
n
‘Linear curve ’
n
‘Lower side band’
n
‘Upper side band’
‘0 - 20 mA’
At 0 mA the pump is stationary –
At 20 mA the pump works at maximum speed.
‘4 - 20 mA’
At 4 mA the pump is stationary –
At 20 mA the pump works at maximum speed.
With current signals of less than 3.8 mA, an error message appears and
the pump stops (e.g. if a cable has broken).
‘Linear curve’
The "Linear curve" symbol appears on the LCD screen. You can enter any
speed behaviour proportional to the current signal. For this purpose, enter
any two points P1 (I1, F1) and P2 (I2, F2) (F1 is the speed at which the
pump is to operate at current I1, F2 is the speed at which the pump is to
operate at current I2...); this defines a straight line and thus the behaviour
is specified:

In the

‘Lower side band’
Using this type of processing, you can control a metering pump using the
current signal as shown in the diagram below.
However, you can also control two metering pumps for different feed
chemicals via a current signal (e.g. one acid pump and one alkali pump
using the signal of a pH sensor). To do this, connect the pumps electrically
in series.
In the
‘Error message’

Explanations:
n If 1 time event (trigger) is to trigger 3 actions that are to have
delays of different lengths, then you need to start 3 delayers and
not just 1 - see instructions 01 to 03.
n If several actions are to be performed after the same delay time,
then you need to write exactly as many instructions – with the same
time event (instructions 07 and 08).
n If, for example, you are using
‘120 s’
, then the action is never performed after the second (longer
delay time because the delayer has been activated after the
smaller delay time and becomes inactive.

WARNING!
Danger from chemical residue
There is normally chemical residue in the liquid end and
on the housing after operation. This chemical residue
could be hazardous to people.
– It is mandatory that the safety information in the
"Storage, transport and unpacking" chapter are read
before shipping or transport.
– Thoroughly clean the liquid end and the housing of
chemicals and dirt. Adhere to the material safety
data sheet for the feed chemical.
WARNING!
Warning of hazardous feed chemical
Should a dangerous feed chemical be used: it may
escape from the hydraulic components when working on
the pump, material failure or incorrect handling of the
pump.
– Take appropriate protective measures before
working on the pump (e.g. safety glasses, safety
gloves, ...). Adhere to the material safety data sheet
for the feed chemical.
–
Drain and flush the liquid end before working on the
pump.
Ä ‘Qualification
CAUTION!
Warning of feed chemical spraying around
Feed chemical can spray out of the hydraulic compo‐
nents if they are manipulated or opened due to pressure
in the liquid end and adjacent parts of the system.
– Disconnect the pump from the mains power supply
and ensure that it cannot be switched on again by
unauthorised persons.
Depressurise the system before commencing any
–
work on hydraulic parts.
Danger of damage to the device
Take into account the information in the "Storage, trans‐
port and unpacking" chapter if the system is decommis‐
sioned for a temporary period.
1. Disconnect the pump from the mains.
2. Drain the liquid end by turning the pump upside down and allowing
the feed chemical to run out.
3. Flush the liquid end with a suitable medium; flush the dosing head
thoroughly when using hazardous feed chemicals!
