Connection

11-pin socket

1The external signal (level relay, pressure switch or float switch) closes the alternation input (6-8).
2On each demand the TABV02 connects the next pump: output 1 (1-3) or output 2 (1-4).
3If the simultaneous input (6-7) also closes, from a level 2 or a high-pressure switch, both pumps run.
4The standby pump is not left idle for months.

Which signal does it need?

An external contact: a level relay, a pressure switch or a float switch connected to the alternation input.

Can both pumps run at the same time?

Yes. Closing the simultaneous input (6-7) switches on both outputs.

Which socket does it use?

An 11-pin socket: the ZB11-0 for DIN rail or the TBEU1E in-line socket.
