12.3.4 External "Contact" operation
The external (remote) control of the pump can take place via voltage-free
contacts (e.g. pulse-type water meters, reed relay) or a transistor in open
collector switching (e.g. optocoupler).

PLEASE NOTE:
The minimum pulse duration is 20 ms; for transistor control the
residual voltage must not exceed 700 mV!
WARNING:
Do not connect the mains voltage to the control cable!
For the external control of the pump you require the 4- pole universal cable
or the 2-pole remote cable which is plugged into the connection socket
(12) and screwed down.
Plugging in is only possible in one certain position!
The brown and black wires of the 4-pole cable are to be bridged; otherwise
the pump stops and "Pause Stop" appears in the display.
By temporarily closing the white wire with the bridged brown/black wire or

maximum stroking sequence is 120 (180) strokes per minute.
If more than the maximum permissible pulses come in these are ignored
by the pump in order to avoid an overloading.
If only external control is planned this can also take place with a 2-wire
remote cable - whereby the bridge is within the plug.
