3.6.3 High pressure safety accessory: SRMCR
– Chiller equipped with VFD LF2
3.6.3.1 General description :
The unit is equipped with a safety loop, also called measurement, control and regulation devices playing a role in
safety (SRMCR for protection against overpressure that could be created by the compressor).
Made of :
-
2 active pressure switches (HPS) at compressor discharge
-
Safety relay K4 inside the control cabinet
-
Power contactor K101 inside the LF2 VFD
-
LF2 VFD
See chiller wiring diagram and bill of material (part numbers).
This SRMCR is designed in accordance with EN ISO 13849-1: 2016 according to the following characteristics:
- PL d
- Category 3.
