above installation precautions. 4. Common Issues and the Possible Solutions (Take ZK- D4330 as an example) 4.1 Power-on failure 4.1.1 The WTMD cannot be turned on, while the power indicator shows nothing 1) Replace the power adapter; 2) If the problem persists, change the power-on button; 3)...
2) If the buzzer is correctly connected, replace the buzzer; 3) Replace the control unit if the false alarm issue persists; 4) Contact the relevant technical personnel if the above doesn’t solve the problem. 4.1.4 After the self-check, the alarm indicator doesn’t function normally 1)...
2) If the infrared sensor works normally, but the problem persists, replace the control unit; 3) Contact the relevant technical personnel if the above doesn’t solve the problem. 4.2.4 Unable to update the parameters 1) Enter the menu to change the parameter; 2)...
4.3.2 No alarm when a passenger carrying suspicious articles is walking through the detector Possible cause(s): the sensitivity may be too low; the infrared sensor might be damaged; the control unit may not be working normally Troubleshooting: 1) Check whether the connection wire between the main engine and the door plate is attached properly; 2)...
1) Check to see if the connection cable is perfectly attached. 2) Cover the infrared tube with an opaque tape to see whether the system triggers the alarm or not; if it does, the cause of the problem is the interference. You may gradually reduce the sensitivity of all or part of the detection zones until the alarm stops.
4) If everything is perfectly fine, but the problem persists, replace the control unit; 5) Contact the relevant technical personnel if the above doesn’t solve the problem. 5. Maintenance (Take ZK-D4330 as an example) 5.1 Clean the surface of the machine regularly Use a smooth cleaning cloth with some industrial alcohol to clean the surface of the control unit, crossbars, and the surfaces of the entire device.
Note: Please carefully pull the connection cable out from the hole, as illustrated below. ③ Remove the two screws at the back of the control unit then remove the metal plate. ④ Install a new control unit, attach it with the metal plate, tighten the screws, and put it back to the crossbar. 5.3 Replacement of an infrared sensor When the WTMD is failed to count the number of alarm events and people walking through the detector, or when the WTMD does not activate the alarm as needed, there might be something wrong with the infrared sensors.
