Checking and adjusting the sensor
Usually, there is no need to adjust the sensor as it was done when
assembled in the factory.
The following are irregular situations that require adjustment:
-There is no screw at the pick up spot but, the LED is on and the escaper
doesn't rotate.
-There's a screw at the pick up spot, but the LED is not on and the escaper
rotates. Check when required.
When checking is required, take the rear cover off and check the voltage level
of No. 7 pin of IC4050 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 pick up spot, turn the power ON.
Next loosen the 2 sensor bracket attaching bolts and do the following:
①
Pull 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 push the sensor
bracket up which causes the voltage to decrease. When the
voltage is around 0.25V
～
1.5V tighten the sensor bracket.
During this procedure when the voltage is around 2.5V, the LED
screw sensor turns OFF and the escpaer rotates.

When there is no screw at the pick up spot, the voltage
is 0.25V
～
1.5V and the LED screw indicator is OFF.
When there is a screw at the pick up spot and the voltage is over 3.5V, the
LED screw indicator is ON.
This is a general standard. The borderline, whether there is a screw in position
or not, is 2.5V.
