Analog Outputs
The Aquavar CPC has two 4-20 mA analog outputs as standard. These outputs may be
configured by the user to output from a selection of nine actual pump signals. Parameter
group 19 is used to configure these outputs. Analog Outputs are found on X1 Terminal Block,
# 2 and # 5 pins. Reference the terminal block diagram on pages 24-31 for detailed wiring
connections.

26.03 SAVINGS 0-65535 If ENERGY SAVNG is selected as an
SCALE Default – 10,000 output, this parameter must be set to
scale the signal. 4 mA = $0.00 and
20 mA equals this amount. For example
20 mA = $10,000.
Auto Restart
The Aquavar drive can be configured to start automatically following a power failure.
Changing the value to ON will enable auto-restart. Selecting OFF disables the auto-restart.
AUTO RESTART is also used with ERROR RESET for automatic restarts following a shutdown
due to a pump fault. AUTO RESTART will also restart the pump once a secondary protection
fault is reset.
Parameter Name Value/Range Note(s)
12.02 AUTO OFF When this is set to “ON “, the Aquavar
RESTART ON (DEFAULT) will automatically re-start after a power
failure or fault reset.
25.04 AR OVER- ENABLE Allows the drive to restart after a motor
CURRENT overcurrent error.
25.05 AR OVER- ENABLE Allows the drive to restart after an
VOLTAGE INPUT OVERVOLTAGE error.
25.06 AR UNDER- ENABLE Allows the drive to restart after an
VOLTAGE INPUT UNDERVOLTAGE error.
25.07 AR AI < ENABLE Allows the drive to restart after a
MIN transducer or analog signal loss.
