Dorma ES 90/100
See also: Commissioning | Adjustment | Functional Testing
This guide allows detailed fault analysis for the Dorma ES 90 and ES 100 systems. In the event of faults during start-up or operation, please consult the checklists and tables below.
Initial System Checks
Before proceeding to detailed diagnostics, verify the following:
- Is mains power available?
- Is the emergency stop push button unlatched?
- Is the program switch in the correct position?
- Are light barrier transmission paths clear and light barriers clean?
- Is the door obstructed by any physical object?
- Are door panels easy to move (check counter-rollers and floor guides)?
- Is the fuse OK?
- Are all external activators, emergency stop switches, program switches, and locks correctly wired?
- Are all plugged connections firmly in place?
If the fault is not remedied by the above, use the Hand Terminal (HT) for fault analysis. Further aids are provided by the diagnostics display on the expansion module.
General Troubleshooting Table
| Fault | Possible Cause | Remedy |
|---|---|---|
| Door operates jerkily and in an uncontrolled manner. |
|
Correctly fit the plug connectors or swap over the wires. Check Incremental Encoder Mode with HT:
|
| After the "4-hourly self-test", the door remains stationary in OPEN-position. | Back-up battery not fully recharged or now spent. |
|
| Door remains open in all program switch settings. |
|
Check light barrier function by observing LEDs on EM4 and HT. Jumper the inputs at the connector. If this rectifies the fault, check the emergency stop switch and replace as necessary. |
| Door does not open in "EXIT ONLY" and "PARTIAL OPENING" settings. | Activator internal/external. | Remove connector for activator and jumper input. If this rectifies the fault, check 24V power supply. If also OK, check the activator and replace as necessary. |
| Door will not open in "AUTOMATIC" and "PERMANENT OPEN" settings. | Emergency stop switch. | Jumper inputs at the connector. If this rectifies the fault, replace the emergency stop switch. |
| Door opens in "OFF" setting. | Program switch. | Adjust or replace program switch. |
| Door stays open (Service display is off). | Short circuit. |
Disconnect control unit from mains power and connect it again after approx. 3 seconds. Note: The 24V power supply for radar detectors, electro-mechanical locks, and motor connection is short-circuit-proof. In event of a short, power interrupts. To reset, remove mains plug, wait 3 seconds, re-insert. |
Troubleshooting for Concealed Rod Multipoint Lock
| Fault / Indication | Possible Cause | Remedy |
|---|---|---|
|
Motor does not respond. Key switch in "Unlocked". 1. Sliding panels unlocked. 2. Panels move twice against upper stop and re-lock. Fault LED lights up. Signal tone emitted. |
|
Operate program switch sequence: AUTOMATIC - OFF - AUTOMATIC. Check continuity from terminal 17 to 20. Connect voltmeter to limit switch terminals. Initiate closing cycle. During closing, voltmeter must show 0V. Alternatively: Remove cable connection for limit switch. Attach multimeter and operate lock manually. Should show 0Ω. Adjust limit switches. |
|
Key switch in "Locked". 1. Sliding panels are locked. 2. Panels move twice against lower stop and are then unlocked. Fault LED lights up. Signal tone emitted. |
The "Locked" limit switch is not being activated. |
Connect voltmeter to limit switch. Initiate closing cycle. During closing, voltmeter must show 0V. Adjust limit switches. Cancel fault signal by operating program switch: OFF - AUTOMATIC or AUTOMATIC - OFF. |
|
Key switch in "Automatic". 1. Lock remains unlocked. Fault LED lights up. Signal tone emitted. |
"OFF" connection of the program switch interrupted. |
Check connection at pin 5. Perform a reset (remove plugs 11/12/13 from ES 90 control unit and re-insert after approx. 2 seconds). |
|
Fault cannot be cancelled using the program switch. Sliding door no longer accepts any opening signal. |
Lock has been pulled over the limit switch by hand. The control receives a stop signal. | Move the lock using the manual unlocking mechanism back to its end position, or operate the lock back into its end position using the key switch. |
Diagnostics & Service Displays
Operational Display (Basic Module GM)
Once mains power has been switched on, the power supply unit is energized (approx. 20 seconds), after which the LED lights up.
| LED Display | Condition | Function |
|---|---|---|
| ⚫ (LED On) | Normal mode | Mains power available, power supply unit energized. |
| ⚪ (LED Off) | Off | Unit not receiving mains power. |
| ◑ (Flashing 2Hz) | Learning cycle | Parameters are being determined and stored. |
Function Display (Expansion Module)
LED 1 and LED 2 signal an interrupted light barrier transmission path. LEDs light up prior to each closing cycle during the light barrier test.
