WARNING
!
If the hydraulic circuit contains air, it may compromise the operation of the unit.
CHECKING THE ELECTRICAL SOURCE
Verify that the circuit breaker is of the correct rating for the unit.
Check that all electrical connections are secure.
Check for false ground contacts as well as all wiring.
Check the internal control and power connections.
Measure voltage on all units, ground, neutral and 3-phase line.
Check that motor overload protection conforms to design requirements and is in automatic mode.
Check voltage (*Motor save), which is set to supply the correct supply voltage for the unit.
* The percentage of unbalance of the power supply must be calculated with the following formula, and adjusted with the UNBALANCE
command.
UNBALANCE PERCENTAGE = [(MAXIMUM AVERAGE DEVIATION) / (AVERAGE)] X (100)
DIAGNOSTIC LIGHT INDICATORS (LED STATUS)
Regular operation
Evergreen
Delayed start
Flashing green
Reverse phase
Flashing red
Phase unbalance
Red in lapses
High/low voltage
Constant red
NOTE: The units are factory set, however the power supply may vary in each installation and due to this imbalance must be
adjusted prior to start-up in order to protect the motors and electrical components of all units.
