Setting of flows
The two flows are set by moving the end stops. At delivery the stops are set at largest
possible distance. If you want to limit the flow span proceed in the following way:
1. The one flow is set by turning the spindle so that the scale arrow points at the
desired flow and thereafter move one of the end stops close up to the clamp's one
heel and lock the stop there.
2. The other flow is set by turning the spindle so that the scale arrow points at this flow
and thereafter move the other end stop close up to the clamp's other heel and lock
this stop there.
Choice of flows
The one flow is chosen by feeding an operating voltage. This voltage, 24 or 230 V, turns
the motor to one of the stops.
The other flow is chosen by breaking the operating voltage. The motor then goes to the
other stop.

The flow is adjusted by loosening the central nut and using the knob to turn the scale
arrow so that it points to the desired flow on the scale. The nut is then locked.
