08-35=1-2: When the temperature is getting higher for the motor and AI2 voltage level is higher than the value
of 08-44, the display will show “OH4 Motor Overheating” and the motor will stop by 08-35=1-2.
08-35=3: When the temperature is getting higher for the motor and AI2 voltage level is higher than the value of
08-44, the display will show “OH3 Motor Temp Warning” but the motor continues running. But AI2 voltage level
is higher than the value of 08-42 and the time reach to 08-39, the motor free runs to stop.
08-35=1-2-3: When the motor cools down and AI2 voltage level is lower the value of 08-43, “OH4 Motor
overheat” will reset.
Note: The resistor (PTC) conform the British Standards Institution:
When Tr is 150 °C in Class F and is 180°C in Class H°
Tr- 5°CRT≤ 550Ω, put the value of RT in formula (1), the V value by calculation is the value of 08-43.
Tr+ 5°CRT≤1330Ω, put the value of RT in formula (1), the V value by calculation is the value of 08-44.
It gets reference value by using formula (1) even in the different spec of resistor (PTC).
