Cylindrical reflective photoelectric switch:
(the function is the same as above) there are 3 lines in total,
including 2 power input, brown + 12V, blue: GND and 1 signal output (black). When a person passes
through the reflective photoelectric switch (reflection distance is 10-20mm), the output is + 12V, otherwise
it is 0V.
1.
After power on, the brake arm rotates back and forth or there is no limit after opening
1)
Determine whether the limit photoelectric switch is exposed to strong light (generally refers to
outdoor installation and debugging).
2)
Test limit photoelectric switch:
a.
Check whether the limit photoelectric switch with zero position, left opening position and right
opening position is powered on! Check the connection base for looseness or poor contact.
b.
Put a piece of iron on the front end of the photoelectric switch (pay attention to be close to the
detection surface) to see whether the light above the photoelectric switch is on. If not, it means
the photoelectric switch is broken. If it is on, adjust the position of the photoelectric switch
appropriately.
3)
Check whether the connection between the limit photoelectric switch and the mainboard is
reliable.
4)
If the limit photoelectric switch and wiring are normal, the motherboard will be damaged.
2.
After giving an effective opening signal, the gate has no action
1)
The mainboard indicator light is normal, when the effective opening signal is given, the indicator
light will turn into a green arrow, and the gate has no action.
Detection method: check whether the motor connection line is well connected. If the motor line is
well connected, use a hand model of the end of the motor to check whether the motor is rotating.
If the motor is rotating, it indicates that the motor line is connected in reverse. If the motor does
not rotate, connect the positive and negative motor line. If the motor does not rotate, it indicates
that the motor is damaged. If the motor rotates, it indicates that the main motor There is a
problem with the motor driver chip on the board. Please contact us to replace the motherboard.
