OPEN/CLOSE impulse

The impulse will open the door and the door will stay open until a new impulse is given. If no impulse

is given the door will close after 15 minutes. This can be made infinite by changing group of para-

meters, see page 77.

OPEN/CLOSE impulse works only in program selection AUTO. Can be programmed for OFF and EXIT

as well.

• In case of power failure, normal operation can be carried out with impulses from the KEY SWITCH.

• Two contacts are available for connection of 2 x 12 V batteries (NiMH).

• DIP-switch for monitoring of batteries is also available. Faulty battery will be indicated by the

LED on the DAB305CU. If selected the relay on DAB905ESA can give a contact information. The

Battery Monitoring always has to be reset, when the batteries have been replaced. It is done by

pressing the Learn button, while battery mode is active (mains disconnected).

Note! If battery mode is POWER SAVE, the reset has to be made during the door is opened by

Key impulse.

• During POWER FAILURE the operator will finish the actual operating cycle and then switch of

the battery supply. The battery powered operator can be reactivated to achieve a new operating

cycle by an impulse on the KEY input.

• The operating mode during battery power can be changed from POWER SAVE to CONVENIENCE,

see page 77. During CONVENIENCE MODE the operator will work as normal until the batteries

are discharged. The batteries are rechargeable and will be charged by the control unit in the

operator. New, fully charged batteries can typically open and close a door max. 300 times in

convenience mode. In power save mode the operator can stand-by in up to 1 week, waiting for

KEY impulse.

The following sensors are not active during battery operation POWER SAVE mode.

- Mat

- Overhead presence detector (OPD/OPS), frame mounted

- Presence impulse approach, door mounted

- Presence detection swingpath, door mounted

Note! All sensors works normally in CONVENIENCE MODE.
