Part Adjustments and Replacement (Continued)
Checking and Adjusting the Sensor
The following are rare situations that require adjustment:
• There is no screw at the pick up spot but, the LED is on and the escape doesn’t
rotate.
• There is a screw at the pick up location, but the LED is not on and the escape
rotates. Check the voltage when required.
• When checking the voltage, 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 location, turn the power ON.
• Next loosen the 2 sensor bracket attaching bolts and do the following:
• Pull the sensor bracket down and check if the voltage is over 4V and if the
sensor light is ON. At this time, the escape is stopped.
• 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 escape
rotates.
• When there is no screw at the pick up location, the voltage is 0.25V-1.5V and the
LED screw indicator is OFF.
• When there is a screw at the pick up location and the voltage is over 3.5V, the
LED screw indicator is ON.
