Protection devices

Independently from the internal motor protection, fuses must be installed before compressor
start-up. The selection of fuses has to be carried out according to VDE 0635, DIN 57635,
IEC 269-1 or EN 60-269-1.
4.5 CoreSense™ Diagnostics
CoreSense™ Diagnostics is used for all 4M* and 6M* Stream semi-hermetic compressors. It
combines oil and motor protection in one module, replacing OPS1/2 and the electronic module
INT69TM. In addition it provides advanced protection against faults such as high discharge
temperature, locked rotor, single/missing phase, voltage imbalance and low voltage protection.
The module is capable of communication via Modbus® protocol. An external overload protection
is not necessary.
