working principle:When the belt conveyor deviates during operation, the edge of the conveyor belt will touch the trigger rod or sensor of the switch. According to the deviation angle, the switch will trigger the following alarms:

• First level alarmWhen the offset angle reaches 15 °, the switch emits a first level alarm signal, which can be used to activate a slight correction device.
• Second level alarmWhen the offset angle reaches 30 °, the switch emits a second level alarm signal, usually initiating shutdown or strong corrective measures.

Installation and Debugging:

1. Installation locationInstall the GHP-250 deviation switch on the two side brackets of the belt conveyor to ensure that the sensor can accurately detect the deviation of the conveyor belt.
2. connectionConnect the wires according to the wiring diagram in the product manual, ensuring that the power supply voltage is 380V.
3. debuggingAfter installation, proceed with debugging. Simulate the deviation of the conveyor belt, check whether the switch can accurately send out the first and second level alarm signals, and activate the corresponding control measures.
