Operation and control module
Operation and control module is designed for integration into mine set electrical equipment (compact stations and control stations) and start-protection apparatus with voltage up to 1140 V of alternate current and frequency 50 Hz, which functions as a remote control device for mining machines and mechanisms and controls machinery ground lead continuity.
The module can be designed in the following versions:
- OCM-01 — for integration into mine set electrical equipment;
- OCM-02 — for integration into mine start-protection apparatus.
Climatic version MCC (moderately cold climate) location category 5 according to State Standard 15150-69. Module electrical diagram is to prevent from:
- control loss in case of short circuit failure or wire breakage of operation and control circuit;
- automatic activation in case of short-term supply voltage rise up to 150% from the rated voltage.
