Operation Modes
Door Closer Mode & Automatic Mode
Users may choose between two operation modes: Door Closer and Automatic Mode.
Door Closer Mode (Parameter hd = 1)
The system is optimised for manual operation. With its optional Power-Assist Function, this mode is tailored to predominantly manually-operated doors where a door closer function is desired.
Automatic Mode (Parameter hd = 0)
This mode is especially suitable for mainly automatic access via motion detector or pushbutton. In addition, the door reverses as soon as it runs into an obstruction while closing.
On activation of the Automatic mode, the wind load control is also available. However, the doors are still ready for manual access. In this case, we would recommend the Push & Go function.
Wind Load Control
ED 100 and ED 250 operators are especially suitable for application at exterior doors that are subject to varying wind loads and for interior doors separating rooms where different pressure prevails.
While the system is in AUTOMATIC mode, the wind load control monitors the actual driving speed and adjusts the speed correspondingly if it does not correspond to the adjusted value.
In conjunction with the Full-Energy Upgrade Card, the operator provides a force of up to 150 N at the main closing edge – which is then used to compensate for environmental influences.
The electronic latching action is activated during the last 5° of the closing cycle in order to support the closing action.
Accessories & Electrical Connection
Apart from the broad range of DORMA accessories, other manufacturers also offer various activators, locking devices, safety sensors, and further accessories that are compatible with ED 100 and ED 250 operators.
DORMA cannot ensure the compatibility of devices from other producers. If third-party components are used, full functionality may not be available, or the operator may work improperly. Furthermore, the operator or the connected component might be damaged.
Activators
The following devices are generally referred to as activators:
- Radar motion detectors
- Passive infrared motion detectors
- Pushbuttons & Switches
- Sensors
- Radio systems & Infrared receivers
- Access control systems
- Telephone systems and intercoms
Minimum Requirements for Activators
Locking Devices
The following devices are generally referred to as locking devices:
- Electric strike plates
- Electric strikes & Motor locks
- Multi-point locking device with feedback contact
- Door magnets
Motor locks without feedback contact can be directly connected to the operator as long as the delayed opening for the locking mechanism amounts to less than 4 seconds.
Minimum Requirements for Locking Devices
In order to ensure that the operator and the locking device work together properly, the locking device has to comply with the following specifications:
Motor lock: 100%
Power Consumption for Accessories
The operator may provide a maximum of 1.5 A at 24 V DC for external accessories. In case you need more power (even if only for a short period of time), an external power supply unit is required in order to avoid malfunctions.
