0530<br />
0530 DISABLE FRQ<br />
30 Hz<br />
Possible settings: 0.0 – 120.0 Hz<br />
Disable frequency (for cascade relay only!)<br />
The frequency to switch off the fixed speed pumps in cascade relay-mode.<br />
If the Master Inverter goes below that frequency for longer than the pre-selected DISABLE DLY [0535] and<br />
the system pressure is higher than the EFFECTIVE REQ. VALUE [03] (REQUIRED VALUE [02] + ACTUAL VAL.<br />
INC [0505]), the first assist pump stops.<br />
0535<br />
0535 DISABLE DLY<br />
5 sec<br />
Possible settings: 0 – 100 sec<br />
Disable delay time (for cascade relay only!)<br />
Delay time before switching off the assist pumps in cascade relay mode.<br />
0540<br />
0540 DROP FRQ<br />
42 Hz<br />
Possible settings: 0.0 – 70.0 Hz<br />
Drop frequency (for cascade relay only!)<br />
This parameter is used to prevent the system from pressure hammers. Before a following pump starts up,<br />
the Master Inverter will drop to the selected frequency. If the DROP FREQUENCY is reached, the follow-uppump<br />
gets released and the Master Inverter will continue with normal operation.<br />
0545<br />
0545 OVERVALUE<br />
OFF<br />
Overvalue (for cascade relay only!)<br />
Possible settings: OFF – pre selected sensor range<br />
If this selected value is reached, an immediate shut-off of the fixed speed pumps is executed.<br />
E.g. REQUIRED VALUE [02]: 70 PSI<br />
OVERVALUE [0545]: 100 PSI<br />
If three pumps are running (1 Master Inverter + 2 fixed speed pumps) and a system pressure of 100 PSI is<br />
reached, one after another assist pump is switched off.<br />
This parameter prevents the system against overpressure in case the HYDROVAR has been parameterized<br />
incorrectly.<br />
0550<br />
0550 OVERVAL DLY<br />
0 sec<br />
Possible settings: 0.0 – 10.0 sec<br />
Overvalue delay (for cascade relay only!)<br />
Delay time to switch off an assist pump in case the actual value exceeds the OVERVALUE [0545] limit.<br />
