Activators

Internal and external activators, a Night-/Bank activator and

an intercommunication system may be connected to the door

system. The internal activator is normally installed inside the

building or room while the external activator is installed on

the outside of the building or room. A Night-/Bank activator

is mounted on the outside and often realised as card reader

or key switch.

Manual locking device

When the door is locked by hand:

• The operator must be adjusted to OFF in order to avoid

damage to the door system.

• If a lock switch is installed, the operator will be

switched off automatically.

DORMA recommends installing a lock switch.

Safety equipment

The required safety equipment in accordance with

the latest state of the common and country-specific

standards, laws, codes and regulations has to be

installed before the system is mounted.

The ED 100 and ED 250 operators may be used in a low-

energy-mode and a full-energy-mode.

Low-Energy-Mode

The low driving speed of the door avoids dangers resulting

from the automatic movement of the door as far as possible.

The door opens at an extremely low speed and thus offers a

high safety level.

7. Malfunctions

Malfunctions may have different reasons.

Ambient conditions often cause malfunctions, thus the

operator tries to analyse these conditions and to respond

correspondingly. In this case the operator interrupts its

currently adjusted function and restarts following a certain

standby-time or when a new pulse has been triggered. In

case this fails, the automatic function of the operator is

switched off and the system displays an error message.

A red LED at the program switch indicates the malfunction.

The LED either blinks or shows a continuous light and

thereby indicates that the malfunction has to be removed by

DORMA Service.

Self-help in case of malfunctions

You have the following options to reset error messages:

Set program switch to OFF or reset the system with

the aid of the RESET key on the user interface while

the cover is open.

Mains reset: Set mains switch to OFF; then wait for 10

seconds and set it back to ON position.

Always analyse and remove the cause for the malfunction

before you acknowledge the respective error message.

Full-Energy-Mode

Due to the high driving speed of the door, the swing path has

to be protected with the aid of sensors.

Safety sensors that are mounted to the door leaf monitor the

swing path and thus avoids that people are hit by the door as

far as possible.

Safety sensors on hinge side

In case an obstruction is detected within the detection range

of the safety sensors:

• The door stops during its opening cycle

• The door remains closed (does not perform an opening

cycle) if the door is in "closed" position.

The operator will resume standard operation as soon as the

detection range is no longer obstructed.

Safety sensors on opposite hinge side

In case an obstruction is detected within the detection range

of the safety sensors:

• The door will reverse during the closing cycle

• The door will remain open.

The operator will resume standard operation as soon as the

detection range is no longer obstructed.

Maintenance interval indicator

In case you have installed the internal 4-position program

switch, you will have a maintenance interval indicator. A

yellow LED informs you that the system has to be serviced.

DORMA Service may adjust the maintenance interval

indicators.

The following table is designed for you assistance.

Please check the following questions in case the door still

does not close or open:

• Is the power supply available?

• Is the mains switch adjusted to ON?

• Is the door freely movable?

• Is the door locked manually? Has the lock switch been

activated?

• Is the program switch properly adjusted (correct

position)?

• Is the swing path unobstructed?

• Has the hold-open device been triggered?

In case you have checked all the above-mentioned questions

and the system still does not work, please contact DORMA

Service to remove the malfunction.
