11.1 BASIC Inverter
The HYDROVAR in configuration BASIC Inverter (only the power unit), is able to indicate
the following errors by the red LED:
red LED Code Error probable cause
1 blink UNDERVOLTAGE DC voltage of the HYDROVAR too low
2 blinks
OVERCURRENT or
OVERLOAD Current rise at the output too high or
power limit of the HYDROVAR is reached
3 blinks INVERTER OVERHEAT Too high temperature inside the HYDROVAR
4 blinks OVERVOLTAGE DC voltage of the HYDROVAR too high
5 blinks CODE ERROR Internal error
6 blinks
MOTOR OVERHEAT
EXTERNAL CONTACT PTC in the conduit box has reached its release
temp. or external contact is open
Reset:
To reset the CODE ERROR and the OVERCURRENT ERROR , the power
supply has to be cut > 60 seconds.
A reset of all other errors can be done by 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.
ERR. BASIC Addr. X
Indication on the MASTER Inverter:
For detailed failure information on the specific unit,
SUBMENU STATUS [20] has to be entered and the affected device has to
be selected with it’s 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 interfere the operation of the other
HYDROVAR units in the system (also valid for automatic Error-reset).
