1. After the power is turned, the swing arm rotates back and forth or after the gate is opened. 1) Check whether the connection between the limit photoelectric switch and the mainboard is reliable;
2) Determine whether the limit photoelectric switch is damaged by strong light (usually refers to outdoor installation and debugging): Put on the cover of the chassis; if it is necessary to open the chassis or movement cover, please cover the limited photoelectricity with a dark opaque object. Switch for debugging; 3) Limit photoelectric switch test:
aã€Check whether the limit photoelectric switch is in the position of zero, left open, right open to the power supply, check whether there is looseness or poor contact of the 4PIN terminal;
b. After entering the debugging menu P00, turn the brake shaft to drive the light block to block the optocoupler of the limit optoelectronic switch with left open, zero and right open positions. When the optocoupler is disconnected, the indicator light is bright and the output voltage is + 12V, otherwise the limit photoelectric switch is damaged;
4) If the limit photoelectric switch and connection are normal, the motherboard is damaged. 2. After the power is turned off, the swing arm is set to be infinite and the power swings after the arm is reversed. 1) The left and right open limit photoelectric switches and the main board are respectively detected. 2) Detect the voltage of dry battery (not less than DC9V);
3) Check if the circuit is loose or unwelded. Check the voltage output (DC12V) of the two terminals MA and MB of CON1 terminal of the power-off control panel. Otherwise, the power-off control board will be damaged. 4) The clearance of the movement is too large, causing swinging arm swing. The light block is moved, and the limit signal is not detected before power-on, causing the motor to reverse. It is normal to block the optocoupler on a lower limit photoelectric switch with a dark opaque object. 3. After the gate is valid, the gate does not move. 1) The main board indicator is normal. When an active gate signal is given, the L7 or L8 indicator will flash intermittently, and the direction indicator will turn into a green arrow. There are 2 different directions. Signals): No action on the gate: Check the PC, PD output voltage (AC18V) of the PX terminal, and check if the F2 (3A) fuse is blown; if it is normal, check if there is voltage output at the MA and MB ends of the DX terminal ( DC24V), if there is output, check whether the motor wire is disconnected; if the motor is damaged; 2) the main board indicator light is off, the LED digital tube has no display: check the PX terminal's PA, PB voltage output (AC12V); F1 (2A) fuse is blown. If all of the above are normal, it is determined that the motherboard is damaged. 4. After the gate is opened, it will not be reset or will be reset immediately after it is opened. When the pedestrian passes the gate, the gate will not be reset immediately (referring to the gate with induction reset function). After a delay, the gate will be locked or Immediately after an open position is reset: Check whether the cylindrical photoelectric switch is on. When there is a signal output, the L2 or L4 indicator on the main board will become bright, otherwise the main board will be damaged. Check whether the main board parameter setting P08 is set to memory. 5. When using an off-line cylindrical photoelectric switch to open the gate 1) Check whether the online connection is not one-to-one correspondence;
2) Check the menu function setting of the main board, P04 menu setting function selection. 6. When the gate is opened online, the two gates are not synchronized. 1) Check the connection line, and if the line is loose or unsoldering;
2) The two gates have different time settings. Check the P03, P17 time parameters. 7. After the power is turned off, the gate will not operate. 1) Check the voltage of the dry battery (not lower than DC9V). 2) Check if the line is loose or disconnected. Check the voltage output of the MA and MB terminals of the CON1 terminal of the power board (DC12V). , otherwise the power-off control board is damaged.
Swing gate common fault analysis summary during use
Pedestrian access gates are electronic products. Inevitably encountering many technical problems in the process of use is difficult to solve. This requires a certain understanding of the problem. The following Xingshun An analysis of several common problems.
