⑤ . Checking and adjusting the sensor
Check when required.
When checking is required, take the rear cover off and check the volt-
age level of No.7 pin of IC4050 on the base and adjust the sensor
bracket. When measuring the voltage level, the metal part of the main
body is the ground.
When a screw is not at the extraction site, turn the power ON.
Next loosen the 2 sensor bracket attaching bolts and do the following:
① . Move the sensor bracket down and check if the voltage is over 4V and if
the sensor light is ON. At this time, the escaper is stopped.
② . Next, while checking the voltage level, slowly move the sensor bracket up
which causes the voltage to decrease. When the voltage is around 0.25V-
1.5Vtighten the sensor bracket. During this procedure when the voltage is
around 2.5V, the LED screw sensor turns OFF and the escaper rotates.
When there is no screw at the extraction site, the voltage is 0.25V-1.5V
and the LED screw sensor is OFF.
When there is a screw at the extraction site and the voltage is over
3.5V, the LED screw sensor is ON. This is a general standard.
The borderline, if there is a screw in position or not, is 2.5V.

① Push the sensor bracket down and check if the voltage
is more than 4V.
② Move the sensor bracket up slowly to reach a voltage of
between 0.25V-1.5V.
