Liebert UPS System Temperature sensor TMP12Z, Level C Lightning Protection System SPD24Z

Chapter 9 Optional Parts

b.Set up the fault call-back parameters. The monitoring system can realize fault call-back functions through the MODEM. When the UPS has fault, it will dial the user automatically and require actions.

9.6Temperature sensor TMP12Z

TMP12Z temperature sensor is an ambient temperature detection device developed by Avansys. Its operation voltage is 12V, the detected temperature range is 0~100℃, and output signal is 1~5V.

Fig.9-6 shows the structure of temperature sensor and meanings of output terminals.

fixing terminal

Fig.9-6 TMP12Z Temperature sensor

The meanings are given below:

Fixing terminal: Use M4~M6 screws to fix the temperature sensor;

VCC: Positive pole of power source of temperature sensor, and generally it is 12V;

GND: GND pole of power source of temperature sensor, and generally it is 0V;

Vout: Output terminal of temperature sensor and the output signal varies between 1V and 5V with the varying of temperature in the range of 0~100℃;

9.7 Level C Lightning Protection System SPD24Z

Level C Lightning Protection System SPD24Z used for SPD-24-UPS can be used to protect the input power source of machine room to prevent the external lightning surge from entering the machine room. SPD24Z should be selected if no lightning protection system lower than level C is equipped in the power distribution system, or the machine room is far away from the power distribution system, or the machine room is in area where the lightning or thunder frequently happens.

The capacity of the Level C lightning protection device is 20kA，the maximum value is 40kA(can only be used one time)，and the surge current is 8/20us.
