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.
9.6 Temperature 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.
