AQUAVAR Controller drive head Technical data and Terminals continued
9 Thermoswitch return connection.
10 Ground connection for analog output.
11 Analog output connection 0 - 10 Vdc, maximum 2 mA. Can be used to
connect an outside meter or display panel to display actual pump running
frequency or pressure as selected on the Analog Out part of the program.
12 Current signal input 4-20mA.
13 Voltage signal input 0-10V or 2-10V.
14 Digital input.
X2 1 Fault signal relay connection. This relay turns on the fault light on the control
panel if a fault occurs. This relay may also be connected to an outside panel or
display through connections 3, 4, and 5. Each is a maximum 250VAC connec-
tion with 1 Amp free of inductivity. Normally Open (NO).
2 Common connection for fault signal relay. 250 VAC with 1 Amp free from
inductivity. (CC)
3 Normally closed connection for fault signal relay. 250 VAC with 1 Amp free
inductivity. Connection 3 is normally closed. (NC)
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 6, 7, and 8. Each is a
maximum of 250 VAC with 1 Amp free from inductivity. Connection 6 is
normally closed. (NC)
5 Common connection for the operation signal relay. 250 VAC with 1 Amp free
inductivity. (CC)
6 Normally open connection for pump operation signal relay. 250 VAC with 1
Amp free inductivity. (NO)
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
current.
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. Always use shielded wire.
