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.

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.
