AQUAVAR Controller Drive Head Technical Data and Terminals
Terminals: There is a terminal strip inside the AQUAVAR controller which will allow the
connection of a wide range of external devices for display or control. When
using these terminals, shielded wires need to be used. Unshielded wires may
produce signal interference which will affect the inverter.
X1 1 Ground connection
2 Actual value input 4- 20 mA, 50 ohm load resistance. Used to connect external
pressure transducer, flow meter, etc. Can also be used as input source from
another device signalling actual speed when “actuator” is selected in
controller mode.
3 Power source for external transducer 15 V DC, max. 25 mA
4 Ground connection for external on/off
5 External on/off connection, 10 kOhm resistance, 5 VDC gold plated contact.
Note that the external device must have a switch suitable for < 10 V. If no
outside panel or control is used, a jumper wire is installed on contacts 4 and
5.
6 Ground connection for low water switch.
7 Low water switch connection, 10 kOhm resistance, 5 VDC. This contact is
where an external level switch, float switch or pressure switch from the suc-
tion line would be installed. If no suction pressure devices are used, a jumper
wire is installed on contacts 6 and 7.
8 5 V power source for the Klixon thermoswitch mounted in the motor conduit
box. 10 kOhm resistance. A jumper wire is installed on contacts 8 and 9.
9 Thermoswitch return connection.
10 Ground connection for analog output
11 Analog output connection 0 - 10 V, 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 1, 2, and 3. Each is a maximum 250VAC connec-
tion with 1 Amp free of inductivity.
2 Common connection for fault signal relay. 250 VAC with 1 Amp free
inductivity.
3 Commonly open connection for fault signal relay. 250 VAC with 1 Amp free
inductivity. Connection 3 is commonly closed.
