Adjusting the Slack Detection Sensor 35
The angles of the slack detection sensor and sensor reflector may not be aligned after adjusting the rails.
In the following case, adjust the angle of the slack detection sensor:
• If only the green lamp of the slack detection sensor turns on when the take-up unit is turned on.
(In a normal case, the orange and green lamps turn on at the same time.)
