1) If door is open, door S/W contact is closed. Then MICOM receives “low” signal and detects

door open then, Relay control circuit receives “HIGH” signal and turn Lamp on.

2) If door is closed, door S/W contact is open. Then MICOM receives “high” signal and detects

door close then, Relay control circuit receives “LOW” signal and turn Lamp off.

6-5. Temperature Sensor

1) The sensor uses the characteristics of thermistor. If temperature goes higher, resistance goes

lower. On the contrary, if temperature goes lower, resistance goes higher.

2) MICOM input voltage is counted by sensor as follows.

CC : 5V, RTH : Sensor reisitance)

3) For the resistance information on temperature and MICOM input voltage, please refer the

conversion table. (Page. 41)

When Sensor is open

MICOM input “HIGH”

When sensor is cut off

MICOM input “LOW”
