Failure Messages<br />
Section 10<br />
Note<br />
If the HYDROVAR is stopped by an error (warning), the HYDROVAR and the motor<br />
remain under voltage. Before any work is carried out on the electrical or mechanical<br />
part of the system, the HYDROVAR must be disconnected from power supply for at<br />
least 5 minutes.<br />
Difference between warnings and errors:<br />
• Warnings are shown on the display and indicated by the red failure LED. If a warning is active and the<br />
cause is not remedied within 20 seconds an error will be shown and the HYDROVAR stops. Note: Not<br />
all warnings will result in an error.<br />
• Errors are indicated on the HYDROVAR display and by the red failure LED on the control panel. In case<br />
of an error the connected motor is stopped immediately. All errors are shown in plain text and saved in<br />
the error memory including date and time when the failure occurred.<br />
The following information describes the errors which can occur on the HYDROVAR (on the Master/Single<br />
and the Basic Inverter). Additionally the possible countermeasures to reset these errors are described.<br />
• Please note that an automatic error-reset can be activated in SUBMENU ERRORS to reset an occurred<br />
failure automatically for 5 times. For more information about this function see parameter ERROR-RESET<br />
[0615].<br />
• All error signals and warnings can be indicated via the two status-relays on terminals X5/1-2-3<br />
or X5/4-5-6 depending on the configuration. (How to program see parameter CONF REL 1 [0715] and<br />
CONF REL 2 [0720].)<br />
10.1 Basic Inverter<br />
The Basic <strong>Hydrovar</strong> (power unit only), may indicate the following errors by the red LED:<br />
Red LED Code Error Probable Cause<br />
1 blink UNDERVOLTAGE DC is too low<br />
2 blinks<br />
OVERCURRENT or Current rise at the output too high or<br />
OVERLOAD current limit is reached<br />
3 blinks INVERTER OVERHEAT Excessive temperature inside the HYDROVAR<br />
4 blinks OVERVOLTAGE Excessive DC voltage<br />
5 blinks CODE ERROR Internal error<br />
6 blinks<br />
MOTOR OVERHEAT PTC in the conduit box has reached its release<br />
EXTERNAL CONTACT temperature or external contact is open<br />
