0215 RAMP 1

4 sec

Ramp 1: Fast acceleration time

Possible settings: 1 – 250 (1000) sec

• Excessively fast running up time may cause an error (OVERLOAD) during the HYDROVAR

starts up.

• Excessively slow running up time may cause a drop of the outgoing pressure during

operation.

0220

0220 RAMP 2

4 sec

Ramp 2: Fast deceleration time

Possible settings: 1 – 250 (1000) sec

• Excessively fast running down time tends to cause an error (OVERVOLTAGE).

• Excessively slow running down time tends to generate over pressure.

0225

0225 RAMP 3

70 sec

Ramp 3: Slow acceleration time

Possible settings: 1 – 1000 sec

• Excessively fast running up time may lead to oscillation and/or an error (OVERLOAD).

• Excessively slow running up time can cause a drop of the outgoing pressure during

variation of the demand.

0230

0230 RAMP 4

70 sec

Ramp 4: Slow deceleration time

Possible settings: 1 – 1000 sec

• Excessively fast running down time leads to oscillation of the HYDROVAR and thereby of

the pump.

• Excessively slow running down time can cause pressure fluctuations during variation of

the demand.

Possible settings: 1.0 – 25.0 sec

Fast running up time to start up the HYDROVAR till the selected MIN. FREQUENCY [0250] is

reached.

Beyond the minimum frequency, RAMP1 [0215] (fast acceleration ramp) starts to work.

• Excessively fast running up time may cause an error (OVERLOAD) during the HYDROVAR

starts up.
