programmer. Refer to details below.
⚫ Enter unlock password and press “Clear” to unlock the
programmer.
⚫ The programmer displays “－”with “Function” and “4”pressed.
⚫ Input corresponding length type and press “Program”, “P” will

4) Other Functions
1) Automatic Compensation for Light
As the detector operates in the dust environment, its emitter
part and receiver part covered with dust will have an impact on its
operation. We add automatic compensation light for its better
performance. As there is dust on the emitter part or receiver part of
the detector, it will judge the dust amount and compensate for
received signals through the inner program and the hardware
circuit, ensuring the detector operates normally in dust
environment. The detector gives fault signals as build-up dust
reaches a certain level and the light compensation reaches the
limit.
2) Self-diagnosis on Optical Signals
The detector can diagnose the emitter, the receiver and the
amplification circuit. The detector can give fault signals as those
parts have something wrong.
