9.6 - Electronic expansion valve (EXV)
The EXV is equipped with a stepper motor (2785 to 3690 steps, depending on the model) that is controlled via the EXV board. The
EXV is also equipped with a sightglass that permits verification of the mechanism movement and the presence of the liquid gasket.
9.7 - Moisture indicator
Located on the EXV, permits control of the unit charge and indicates moisture in the circuit. The presence of bubbles in the sight-glass
indicates an insufficient charge or non-con-densables in the system. The presence of moisture changes the colour of the indicator
paper in the sight-glass.
9.8 - Filter drier
The role of the filter drier is to keep the circuit clean and moisture-free. The moisture indicator shows, when it is necessary to change
the element. A difference in tempera-ture between the filter inlet and outlet shows that the element is dirty.
9.9 - Sensors
The units use thermistors to measure the temperature, and pressure transducers to control and regulate system opera-tion (refer to
the 30XA/30XAS/30XW Touch Pilot control manual for a more detailed explanation).
9.10 - Power factor correction capacitors (option 231)
They garantee a minimum power factor performance of 0.95 when unit operates at a condition that involves a power input that exceeds
the Eurovent standard condition.
A fix capacitor bank is switched at start of each compressor. It provides individual power factor correction for each machine refrigerant
circuit.
Capacitors are dry type : no risque of leakage or fire.
The capacitors are selected for each compressor as per below table:

CAUTION: Operation of the unit without capacitors results in current raising.
