Main motor phase unbalance protection:
A priori, the measured voltage value for each phase must be equal. Unbalance protection measures any deviation from this condition. If the
measured value in any of the 3 phases deviates over the value set in P14.06 (percentage), the interface stops the compressor.
Protection by main motor phase angle:
No setup is required! The interface monitors the sequence of phases 1, 2 and 3 and the corresponding angles.
Phase L1 angle = 0°
Phase L2 angle = between 100° and 140°
Phase L3 angle = between 220° and 260°
If the phase angle error occurs, the interface will stop the compressor immediately.
Protection for current sensor or wiring interruption failure:
If the measured current falls below 20% of the rated current value when the motor is running, the interface will assume that there is an error in
the current sensor or wiring failure.
8.7 CONFIGURABLE MENUS
The interface has a number of configurable menus to restrict compressor malfunctions, as shown below.

For safety reasons, some equipment requires the door to be closed to release the operation. Blocking the operation can be
performed through a digital input (see instructions on setting up a digital input).

This parameter is used to prevent the compressor from starting when the internal pressure is too high.
For this operation, the compressor must have a pressure sensor installed in the internal air/oil tank. If this sensor isn't
available, this parameter must be disabled.
High INT PRESS
Press 'ENTER'. Use the 'UP' and 'DOWN' arrows to set between 0.1BAR and 2.0BAR (in BAR or other selected pressure
unit). Press 'ENTER' again. The set value is stored in memory and the browser returns to P15.04.
