Behaviour EXT. OFF for twin-head pumps

The function EXT. OFF always behaves as follows:

• EXT. OFF active: contact is open, pump is stopped (OFF).
• EXT. OFF inactive: contact is closed, pump runs in normal operation (ON).

Pumps from SW ≥ 01.05.10.00: The configuration of the control inputs has three possible modes for EXT. OFF which can influence the behaviour of the two dual-pump partners.
