Xylem IM131R01 AQUAVAR AV II - Manual (Page 89)

4 ** Pump operation signal relay connection. This relay turns on the run light on
the control panel when the pump is operating. This relay may also be connect-
ed to an outside panel or display through connections 4, 5 and 6. Each is a
maximum of 250 VAC with 1 Amp of free inductivity. Connection 6 is commonly
closed. Four, 5 and 6 are fault relay’s connected to internal drive.
5 ** Connected to internal drive. (For fault relay, use internal drive connection.)
6 ** Connected to internal drive. (RC2, NC2, NO2, Diagram 8, page 25)
X5/6 1 RS-485 interface connection. SIO - (low) for connection of the AQUAVAR
controller to other AQUAVAR controller units in a set, or to an outside controller.
2 RS-485 interface connection. SIO + (high) for connection of the AQUAVAR controller
to other AQUAVAR controller units in a set, or to an outside controller.
3 RS-485 interface connection. Common ground.
4 RS-485 interface connection. +5 VAC output signal. Maximum 20 mAmp output.
X9 6 24 VDC supply, connected to drive, control board supply
5* Connected to drive, +24 VDC power to control board
4* +24 VDC (jumper wire) connected to drive
3 Connected to drive (fault relay)
2 Analog out signal, 0-10 VDC (pressure reference)
1 Return signal for analog out
* Jumper wire installed at factory, do not remove.
** X2, 4, 5 and 6 contacts are connected to the internal drive for a run light relay. (Pump run) For an external run relay, use internal
drive connections on TB3, RC2, NC2, NO2, located in Diagram 8, page 25. TB3 terminal block specifications, located on page 26.

Appendix B
When using the RS-485 connection for multiple pump connection, connections X5 1, 2 and 3, must be
connected with three core shielded wire to like connections on each AQUAVAR controller drive head.
