Process control system: In the process control system of chemical, pharmaceutical, water treatment and other industries, real-time monitoring and control of temperature, pressure, flow, liquid level and other process parameters can be carried out to ensure the safety and stability of the production process.

Intelligent building automation system: It can be applied to the lighting system, air conditioning system and lift control system of the building to achieve automated management and energy-saving control of the building equipment, and improve the comfort and energy utilisation of the building.

The transfer sequence of OTM_C21D can be summarized in following steps: 

• An anomaly occurs on the Line 1 (LN1) 

• Generator start, immediately start generator in case of black-out, phase-loss, overvoltage or undervoltage (If Generator mode is selected) 

• The Line 2 start the normal functioning,  transfer delay Ts 

• Change-over switch (Switch I) to the position 0 

• Change-over switch (Switch II) to the  position II

And the return sequence can be summarized in  the following steps: 

• The Line 1 will start the normal functioning 

• Change-over switch stays in position II 

• An anomaly occurs on the Line 2 (LN2) 

• Change-over switch stays in position II 

• Change-over switch can be transferred  manually back to position I
