13. Diagnosis / Troubleshooting
DORMA operators meet high safety standards and fulfil all required technical rules and requirements. The system monitors internal as well as external safety circuits that are governed by the operator.
While the operator is in use, certain situations might cause error messages. The operator tries to find the reason for the error and responds correspondingly. The reaction depends on how severe the error was and may vary from a simple notification to the deactivation of the Automatic Function. In this case, the operator will switch to emergency operation and act like a door closer. Users may access the door manually.
Note: Information "In" and error messages "E0"..."E9" are displayed on the user interface display and by the red LED at the internal program switch. The LED emits a blink code that is to be found in the error code table.
Error messages "E0" ... "E9" are stored in the error log and can be read out at the user interface display or with the aid of the DORMA hand-held terminal. The current (latest) error message is always stored as error message E0.
As soon as another error occurs or after the error has been acknowledged, the former error will become error E1. Thus a total of not more than 9 errors can be stored in error memory (E1 – E9). If the same error occurs several times in a row, it will not be stored anew.
Handling "In" information
The provided information is designed to enhance the service friendliness of the operator and indicates faulty system statuses as well as operating statuses that interrupt the Automatic Function of the operator.
- In08 → The Emergency Off pushbutton has been activated and thus the operator does not perform Automatic functions.
- In01 → The system is blocked and the operator continues operation.
If an info message occurs several times, it might be modulated into an error message.
Handling error messages "E0" ... "E9"
Error messages are an indicator for defective hardware. However, improper mounting and the manual use of the door system during safety tests may also cause error messages so that the system switches to emergency operation. You have the following options to reset errors:
- Set program switch to OFF or reset the system via the Reset button of the user interface while the cover is open.
- Power reset: Switch off mains switch then wait ten seconds before you switch it on again.
Always analyse and remove the cause for the malfunction before you acknowledge the respective error message.
General Malfunction Troubleshooting
| Malfunction | Possible Reason | Remedy |
|---|---|---|
| The door can only be used manually or the door does not open automatically after an opening pulse has been emitted. |
Check the green LED. In case the green LED is not on, there is a problem with the power supply. Check the red LED. In case the red LED at the main switch blinks, the control unit has detected a malfunction and the system now operates in emergency mode. The program switch is adjusted to OFF or EXIT ONLY. The safety sensor on the hinge side has emitted a signal and thus the door does not open. |
The mains switch must be switched on. Check and restore power supply if required. In case the power supply is properly connected and activated and no 24 V DC power supply is available, the power supply unit has to be replaced. You will find troubleshooting instructions in the following list: Information and error messages. Adjust program switch to AUTOMATIC or PERMANENT OPEN. The signals of the safety sensors are indicated via the two decimal points on the LED display of the user interface. The respective decimal point illuminates if the sensor has detected something. Check the wiring and the sensor for proper functioning. If the LED in the upper left corner blinks, the wall blanking is activated – the blinking does not indicate an error. |
| During installation: It is extremely difficult to open the door manually and the door closes at high speed. | The connector of the braking circuit is positioned incorrectly. | The connector has to be positioned according to the prevailing arm. (See picture 16 on detailed manual, page 15). |
| The system does not start the learning cycle. | The program switch is adjusted to the wrong position. Signal 4/4a (deactivation of operator function) is activated. |
Set program switch to OFF. Check cabling of smoke detector or interrupt signal at 4/4a. |
| The internal/external program switch does not work properly or faulty. | The parameter for the program switch type is adjusted incorrectly. The cable of the internal program switch is not connected. Faulty connection/defective switch. |
Adjust the parameter for the installed program switch type properly. Check and connect cable if required. Check the wiring and the function of the switch. |
| The door opens automatically, however, it does not respond at all or only after a sustained period of time. | The hold-open time is adjusted too long. The program switch is adjusted to PERMANENT OPEN. The safety sensor on the opposite hinge side has emitted a signal and thus the door does not close. One of the connected activators emits a signal so that the door cannot close. |
Reduce corresponding parameter. Change program switch position. Check signals via LED display decimal points. Check the wiring and the sensor for proper functioning. Check the wiring of the connected activators. A NO contact has to be installed in any case. Signal input 57/57a may be operated with external voltage. Signal input 35, 57, 42 and 41 must be removed one after the other in order to localise the error. |
| The driving speeds vary heavily from the adjusted parameters. | The learning cycle has been performed while the motor was hot, therefore the system has calculated an incorrect door-leaf weight. | Restart learning cycle while the motor is cold. |
Detailed Code List: Information & Error Messages
Information Messages ("In")
| Code | Meaning / Cause | Troubleshooting |
|---|---|---|
| In 01 |
Obstruction The door is obstructed by an obstacle and the operator-driven door cycle has been stopped. |
Check the movement of the door while the system is de-energised and remove cause for unsmooth running. If a defective door is operated over a sustained period of time, the operator might be damaged. Check if detection range of sensors fits opening speed. Increase detection range and/or opening speed if necessary. Test system efficiency. |
| In 03 |
Temperature Management Program activated The TMP is designed to prevent the operator system from overheating. It responds to overload by reducing dynamics, increasing hold-open time, or switching on fan. |
Check and improve heat transmission if required. Avoid direct sunlight. Ensure sufficient space between system and external heat sources. Check if heat conductive pads were removed during mounting. |
| In 08 |
Deactivation of operator function Contact 4/4a is open. The operator switches to emergency operation (manual access only). |
An emergency pushbutton, lock switch or other safety system connected via input 4/4a has triggered or is defective. Reset the activation. Check cabling if automatic operation does not resume. |
| In 09 |
Signal error of Upgrade Card Installed Upgrade Card removed or not re-plugged correctly. |
Upgrade Cards must remain connected permanently. If multiple cards are used, the first one plugged in (Container Module) must be reconnected. |
|
In 11 Red LED illuminates |
Triggering of hold-open device Smoke detector or manual release triggered. |
System must be reactivated via active process (opening door manually to taught-in angle, toggling PGS, or reset). Ensure smoke detector is not triggering signal. |
| In 23 |
Door locked signal Door is blocked in "closed" position. |
Mainly occurs if door is locked. Install a lock switch to recognise bolt status and switch off operator to prevent damage. |
| In 61 |
Communication error of double-leaf systems Operators communication interrupted. |
Check linking cable. Perform visual inspection of control unit interface. |
| In 72 |
Current measuring circuit Cyclical test of internal current measuring circuit was not successful immediately. |
System tolerances or environmental conditions may affect test. Test repeats automatically. Only an issue if permanent error E72 occurs. |
| In 73 |
Braking circuit test Cyclical test of internal braking circuit failed at first attempt. |
Test repeats. If test fails 10 times in a row, system emits error E 73. |
| In 91 |
DCW communication Registered DCW device missing. |
Reconnect device. If not possible, perform restart (Press and hold both keys at internal control panel for 3 seconds). |
