Minimum threshold limit
disabled
Possible settings:
disabled - max. SENSOR RANGE
• An adjusted value >0.00 has to be reached within the programmed DELAY TIME [0610]
• If this value can’t be reached, the HYDROVAR stops with the failure message ”MIN. THRESHOLD ERROR”.
• To disable the minimum threshold limit, press

till “disabled” is shown on the display.

0610 DELAY - TIME
Minimum threshold limit delay time
2 Sec
Possible settings:
1 – 100 sec
Delay time to switch-off the HYDROVAR if the actual value drops below the minimum threshold limit or a
connected external low water protection at terminals X3/11-12 has been opened.
notice: The minimum threshold function is also active during start up of the pump! Therefore the delay
time has to be set higher than the duration that is needed, to reach a value above the limit.

0615 ERROR RESET
Automatic error reset
ON
Possible settings:
ON – OFF
on: Allows an automatic restart for 5 times in case of a failure. If the failure is still active after the 5th restart,
the HYDROVAR will shut off and the appropriate error message is shown.
The internal counter of the automatic error reset is decreased by 1 after each operating hour, so if an error
could be reset after 3 restarts, there are 3 further restarts possible after one hour, 4 after two hours and 5
automatic restarts after 3 operating hours. A manual reset can be done by switching an external ON/OFF
(X3/7-8) contactor.
