NOTE
If the HYDROVAR is stopped by an error (warning), the HYDROVAR and the motor remain
under voltage. Before any work is carried out on the electrical or mechanical part of the
system, the HYDROVAR must be disconnected from power supply for at least 5 minutes.
Difference between warnings and errors:
Warnings are shown on the display and indicated by the red failure LED. If a warning is active and the cause is
not remedied within 20 seconds an error will be shown and the HYDROVAR stops. Note: Not all warnings will
result in an error.
Errors are indicated on the HYDROVAR display and by the red failure LED on the control panel. In case of an
error the connected motor is stopped immediately. All errors are shown in plain text and saved in the error
memory including date and time when the failure occurred.
The following information describes the errors which can occur on the HYDROVAR (on the Master/Single and the
Basic Inverter). Additionally the possible countermeasures to reset these errors are described.
• Please note that an automatic error-reset can be activated in SUBMENU ERRORS to reset an occurred failure
automatically for 5 times. For more information about this function see parameter ERROR-RESET [0615].
• All error signals and warnings can be indicated via the two status-relays on terminals X5/1-2-3 or X5/4-
5-6 depending on the conguration. (How to program see parameter CONF REL 1 [0715] and CONF REL 2
[0720].)
10.1 Basic Inverter
The Basic Hydrovar (power unit only), may indicate the following errors by the red LED:
Red LED Code Error Probable Cause
1 blink UNDERVOLTAGE DC is too low
2 blinks
OVERCURRENT or Current rise at the output too high or
OVERLOAD current limit is reached
3 blinks INVERTER OVERHEAT Excessive temperature inside the HYDROVAR
4 blinks OVERVOLTAGE Excessive DC voltage
5 blinks CODE ERROR Internal error
6 blinks
MOTOR OVERHEAT PTC in the conduit box has reached its release
EXTERNAL CONTACT temperature or external contact is open
To reset the CODE ERROR and the OVERCURRENT ERROR, cut power
Reset:
supply for > 60 seconds.
To reset all other errors open/close the START/STOP_PTC input (X1/PTC) on
the power unit.
If the Basic Inverter is used in combination with a Master Inverter, each failure can be indicated on the
Master Inverter too and will be saved in the failure memory including date and time when the failure appeared.
Indication on the Master Inverter: For detailed failure information on the
ERR. Basic Addr. X specic unit, SUBMENU STATUS [20] has to be entered and the affected
device has to be selected with its pump address!
If a Master Inverter is used in such a system, the errors which occurred on the Basic Inverter can be reset by
the Master without interfering with the operation of the other HYDROVAR units in the system (also valid for
automatic Error-reset).
