11.10. Voltage Monitoring – VCC
The voltage control relay, is an additional device which stops the power supply to prevent faults if
the voltage not in rated tolerance. The relays monitors according to the respective setting an voltage
whether it exceeds or falls below a specified value or is within a certain range (window monitoring)
The relay installed in the electrical box has a display and can be parametrized with three keys.
The display shows the present value and a symbol that indicates whether the relay is set to
monitor whether the voltage exceeds or falls below a specified value or whether it is set to window
monitoring. The setting range for the upper and lower threshold values extends from 17 V to 275 V.
Reset function: Auto- or manual reset selectable.
ATTENTION
Setting of this component is made in factory and must not be altered.
11.11. Monitoring of phase sequence and phase loss (for 3-phase scroll
compressors) – PSCR
Protection relay for phase sequence and phase loss installed in the electrical box. In case of incorrect
phase sequence or phase loss, the relay automatically switch off the compressor to protect them from
damage . Automatic reset when failure is no longer present. LED indication for power on and fault.
11.12. Soft start for three-phase compressor – SOFTT
DANGER
Hazardous voltage: will cause death or serious injury. Disconnect power before working on
equipment.
ATTENTION
Setting of this component is made in factory and shown in the wiring diagram. Before altering it,
contact STULZ service.
