Connection

11-pin socket

1The first-level external signal (level relay, pressure switch or float switch) closes input I1 (6-7).
2On each pulse the TABV03 connects the next pump: O1 (1-3), O2 (1-4) or O3 (1-5).
3When demand rises, input I2 (6-8) adds a second pump and I3 (6-9) the third.
4This optimises the running times of the three pumps.

Can all three pumps run at the same time?

Yes, by activating inputs I1, I2 and I3 at the same time.

Which signal does it need?

External contacts: level relays, pressure switches or float switches connected to the inputs.

Which socket does it use?

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