Pump configuration
Electrical Interface:
• Open contact voltage: approx. +5 V
• Input resistance: 10 kΩ
• Control: volt free contact (0.5 mA at +5 V).
or: semi conductor switch (residual voltage < 0.7 V)
• minimum contact duration: ≥ 20 ms

pin 5 auxiliary frequency – – grey
”Pause“ Function
The pump runs when
• There is no cable connected (e.g. pin 1 free)
• The cable is connected and the contact is earthed (pins 1 and 4 connected).
The pump does not run when
• The cable is connected and the contact is open (pins 1 and 4 not connected).
”External“ Operating Mode
A dosing stroke is triggered when a contact is made for a minimum of 20 ms with pin 2 (external)
and pin 4 (earth), and the ”pause“ input is at pin 4 (earth).
Operating Characteristic Variations: Changing from ”External“ to ”Manual“
The operation of the Beta
®
pump when changing from ”external“ to ”manual“ options
(when external cable is connected) takes two forms:
Identity code: ”control type“
• 0: no lock
”External“ and ”manual“ operating modes can be activated at any time. All pump functions
correspond to the texts on the multifunction switch and the pre set operating mode. The pump
operates in ”manual“ mode even when external cable is connected. This is the standard
version.
• 1: with lock
The ”external“ operating mode is only available when external cable is connected.
The ”manual“ function is only available when the cable is removed.
Altering External Frequency Function (Auxiliary Frequency)
This function switches the pump over to a pre-programmed frequency, as long as the correct
input is connected to pin 4 (reference potential) and the pump is not in ”pause“ or ”stop“ modes.
The ”auxiliary frequency“ function overrides a manually set operating frequency and also
”external“ operating mode.
If the ”auxiliary frequency“ function and the ”pause“ function are both active the pump stops. In
the standard version this function is programmed to 100 % stroking rate.
