X1

Control Wiring

1

SCR

Terminal for transducer shield. (Connected internally to chassis ground.)

Analog input channel 1, 2nd transducer. Default

2

= frequency reference.

2

AI1

Resolution 0.1%, accuracy ±1%.

J1:AI1 OFF: 0…10 V (Ri = 312 kΩ)

J1:AI1 ON: 0…20 mA (Ri = 100 Ω)

Switch positions listed on page 25.

3

AGND

Analog input circuit common. (Connected internally to chassis gnd.

through 1 MW. Jumper wire to X1-11.)

4

+10 V

10 V/10 mA reference voltage output for analog input potentiometer,

accuracy ±2%. (Not used.)

Analog input channel 2.

5

AI2

Resolution 0.1%, accuracy ±1%.

Transducer input

4–20 mA

6

AGND

Analog input circuit common. (Connected internally to chassis gnd.

through 1 MΩ)

7

AO1

Analog output, programmable. Default

2

= Not used. Current 0…20 mA

(load < 500 Ω)

8

AO2

Analog output, programmable. Default

2

= Not used. 0…20 mA

(load < 500 Ω)

9

AGND

Analog output circuit common (Connected internally to chassis gnd.

through 1 MΩ)

10 +24V

Auxiliary voltage output 24 VDC / 250 mA (reference to GND). Short

circuit protected. Transducer/digital input power supply.

11 GND

Auxiliary voltage output common. (Connected internally as floating.)

Digital input common. To activate a digital input, there must be ≥+10 V

12 DCOM

(or ≤-10 V) between that input and DCOM. The 24 V may be provided by

the AQUAVAR (X1-10) or by an external 12…24 V source of either polarity.

13 DI1

Digital input 1, programmable. Default

2

= run enable (Group 24)

14 DI2

Digital input 2, programmable. Default

2

= low water (Group 24)

15 DI3

Digital input 3, programmable. Default

2

= E-stop or jumper

16 DI4

Digital input 4, programmable. Default

2

= set point selection

17 DI5

Digital input 5, programmable. Default

2

= HOA (Group 12)

18 DI6

Digital input 6, programmable. Default

2

= not used

19 RO1C

Relay output 1, programmable. Default

2

= drive ready

20 RO1A

Maximum: 250 VAC / 30 VDC, 2 A

21 RO1B

Minimum: 500 mW (12 V, 10 mA)

22 RO2C

Relay output 2, programmable. Default

2

= pump run

23 RO2A

Maximum: 250 VAC / 30 VDC, 2 A

24 RO2B

Minimum: 500 mW (12 V, 10 mA)

25 RO3C

Relay output 3, programmable. Default

2

= fault

26 RO3A

Maximum: 250 VAC / 30 VDC, 2 A

27 RO3B

Minimum: 500 mW (12 V, 10 mA)

1

Digital input impedance 1.5 kΩ. Maximum voltage for digital inputs is 30 V.

2

Default values depend on the macro used. Values specified are for the default macro, single/multipump.

NOTE: Jumper Wires between 3 and 11, 10 and 15, 11 and 12.

NOTE! Terminals 3, 6 and 9 are at the same potential.

NOTE! For safety reasons the fault relay signals a “fault” when the AQUAVAR is
powered down.
