5 How the Ditec DAB305 works
The swing door operator Ditec DAB305 uses a DC motor which is connected to the output shaft
by a combination of a worm gear and spur gears. The push- or pull arm system that is connected
to the output shaft opens the door in a surface mounted application.
There is an adjustable spring mechanism, consisting of a helical compression spring combined
with a linkage system including a pressure roller that acts on a cam curve that is attached to the
output shaft. During opening of the door, the compression spring is tensioned by the rotation of
the output shaft. During the closing cycle, the accumulated spring force is transferred to the output
shaft by means of the cam curve and the pressure roller. The transferred spring force is acting in
the closing direction.
The spring force can be adjusted so that there is appropriate force to close the door when it is
manually operated or if there is a power failure.
It is possible to increase the closing force by using the motor in combination with the spring and
thereby increase the door closing force (powered close).

5 How the Ditec DAB305 works

5.1 Opening
When an activation signal is received by the control unit, the door is opened at the installer-adjusted
opening speed. Before the door is fully open at back check, it slows automatically to low speed.
The motor stops when the selected door opening angle has been reached. The open position is
held by the motor.
If the door is obstructed while opening, it will either stall or stop which can be selected with a DIP-
switch (SOS). Stop on stall is always active in program selector Mode Off.
•Continue on stall - the door will continue to try to open during the hold open time.
•Stop on stall - the door will, even if hold open time has not expired, close after 2 seconds.
5.2 Closing
When the hold open time has elapsed, the operator will close the door automatically, using spring
force and motor. The door will slow to low speed at latch check before it reaches the fully closed
position. The door is kept closed by spring power or combined with extended closing torque by
the motor.

5.4 Functions on the basic control unit CUS7 (DAB305CU)
See page 59 for more information.
5.4.1 Power failure
During power failure the operator acts as a door closer with controlled closing speed and a micro
switch will make a lock kick to secure latching (only fire rated version and no Inverse installation).
5.4.2 Closing torque
To comply with authority requirements or to overcome over/under pressure the closing torque
can be adjusted according to EN1154.
1020527-DIen-3.0Issue 2021-06-0714
5 How the Ditec DAB305 works

5.4.3 Extended closing torque (CLTQ)
If the potentiometer CLTQ is set to 0°, the door will close with normal spring power. If the poten-
tiometer is turned clockwise, the motor will increase the closing torque. Extended closing torque
will be reduced to zero:
•If the door mounted sensor is activated in closed position or during closing (even if manually
opened). Applies not to program select OFF.
Also, Extended closing torque will be canceled after the first closing by KILL, in all program se-
lections (except secondary door with older firmware).
5.4.4 Power assist (POAS)
If the potentiometer POAS is set to 0°, the door gives no power assist. If the potentiometer is turned
clockwise, the motor will give/increase power assist when the door is opened manually. The range
of the POAS is depending on the spring pre-tension.
5.4.5 Push and go (PAG)
DIP-switch to select Push and Go, ON or OFF. Push and Go is available from any door position. Push
and Go is not active in programme selector setting OFF.
5.4.6 Inverse (INV)
DIP-switch to select when inverse installation.
To be used for doors in emergency escape routs where the door has to open in case of fire alarm
(smoke evacuation). The door is opened by spring force and closed by motor operation. If lock is
used, the lock must fulfill the ELtVTR-standard.
5.4.7 Activation delay (AD)
This function requires a constant inner impulse for the specified time before the door will open.
Fixed 2 sec.
During closing the door will reopen immediately if impulsed.
5.4.8 Overhead presence detector (OPD), frame mounted
When an OPD sensor is mounted on the frame or operator cover just above the swing side of the
door, it will–when activated–either keep the door open or closed. The sensor input is not sensative
during opening and closing. Lock-out signal is available as it is required by some OPD sensors for
proper function.
•a closed door will not open, if the OPD detects activity in the field
•an open door will not close, if the OPD detects activity in the field
•during opening, the door will continue to open, even if the OPD detects activity in the field
•during closing, the door will continue to close, even if the OPD detects activity in the field
•the OPD is not active in program mode OFF, manually opened door or during battery operation
(Power Save Mode).
5.4.9 Mat
Mat safety means that:
•a closed door will not open, if someone steps on the mat
•an open door will not close, if someone steps on the mat
•during opening, the door will continue to open, even if someone steps on the mat
•during closing, the door will continue to close, even if someone steps on the mat
•opening impulses are prevented during closing, if someone steps on the mat
•the mat is not active in program mode OFF, manually opened door or during battery operation
(Power Save Mode).

5.5 Functions on the extension unit DAB905ESE
Also see page 61 for more information.
5.5.1 KILL or FIRE function
In the event that the KILL or FIRE circuit is activated, all Safety Functions of the
door will be overridden causing the door to close even though an object or
person may be in the door's path of travel, and therefore may be subject to injury.
This mode of operation is most generally used to isolate an area in the event
of a fire. In double doors, coordinator shall be used to ensure correct closing.
•During KILL the control will ignore all signals and close door(s) at normal speed or 5 seconds
(see page 72).
•If impulse controlled KILL or FIRE: The operator will resume normal operation after a KILL RESET.
When manual RESET, jumper must be removed and reset button connected to terminal No. 8
and Ground.
•Or if state controlled KILL When KILL signal is no longer active, operator will resume normal
operation.
•The behavior of the lock during KILL depends on the group of parameters. See page 77.
•Green LED indicates trouble-free operation of the operator. No triggering of the connected
devices (smoke detector or manual release button).
•Red LED indicates the release of one or more triggering devices (smoke detector or manual re-
lease button). This display is rated as kill or fire mode.
5.5.2 Function of locks
•The lock output is short circuit proof and can source a lock with 24 V DC, max. 600 mA. Lock
function is active in programme selection EXIT and OFF
•The control has an available output of DC for external locks
•DIP-switches to select 12 or 24 V DC, locked with or without power
•DIP-switch for lock release and potentiometer for opening delay
•DIP-switch for lock kick to overcome binding in the locking device during closing (inactivated
for Inverse door)
•Input to unlock signal from lock. Potentiometer for opening delay is to be set to max. As soon
as unlock signal is received the door will start to open. The lock output signal shall be active
low.
•If the door cannot fully close, the operator will perform a lock retry (once if manually, twice if
automatically open).
5.5.3 Program selector (wall mounted)
•Input for OPEN, EXIT and OFF (if no program selector, AUTO is default).
Note! In OFF-position the operator will comply with the Low Energy Regulation and the door
mounted sensors will be disregarded.
5.5.4 Impulses
•Input for OUTER impulse, KEY impulse and OPEN/CLOSE impulse.
1020527-DIen-3.0Issue 2021-06-0716
5 How the Ditec DAB305 works

5.5.5 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.
5.5.6 Power failure mode (backup batteries are installed) –optional
•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

5 How the Ditec DAB305 works

5.5.7 Nurse and bed functionality
Solution 1
Connect a bridge between 3 and 7 on the secondary DAB905ESE.
Use any impulse on primary to open primary door.
Use Open/Close impulse on secondary to open both doors.
Solution 2
Connect a bridge between 3 and 7 on the secondary DAB905ESE.
Set dip switch PAG on primary board to ON.
Use any impulse on primary to open primary door.
Push secondary door manually and it will open up automatically and stay open until primary door
is closing.
Active in Program Selection OFF, EXIT, AUTO and OPEN.
Solution 3
Connect a 1/0 switch between 3 and 7 on the secondary DAB905ESE.
Switch in pos. 1, impulses on primary will open only primary door.
Switch in pos. 0, impulses on primary will open both doors.
Solution 4
Connect a bridge between 3 and 7 on secondary DAB905ESE.
Set dip switch PAG on secondary board to On.
Any impulse on the primary control unit:
- Shorter than 2s opens only primary door.
- Longer than 2s opens both doors.
Note! How to connect KILL input is determined by chosen parameter group at the secondary, be
sure that chosen group has KILL-impulse configuration Normally Open. If KILL has to be Normally
Closed, terminal 3 and 7 should be disconnected instead of connected.
5.6 Functions on the extension unit DAB905ESA
Also see page 62 for more information.
5.6.1 Presence impulse approach, door mounted
The presence impulse is active during fully open and closing. The sensor is mounted to the approach
side of the door. Once the door is closed, the sensor is ignored and will not be active until the next
impulse is received.
Note! When installed as a pair of doors, the presence impulse signal will re-open both doors. The
sensor is not active in program mode OFF, manually opened door or during battery operation
(Power Failure Mode).

5 How the Ditec DAB305 works

5.6.2 Presence detection swingpath, door mounted
When a sensor that is mounted on the swing side of a door detects an object, it will send a command
to the control unit to stall the door. If the control unit has received a short signal from the sensor
and there is still hold open time left on the control unit, the door will continue on its way open if
the object has cleared.
The inhibit/blanking potentiometer can be adjusted so that the sensor will avoid detecting a wall
or object near the full open position. Presence detection has a higher priority than presence impulse.
Note! When installed as a pair of doors the presence detection signal will stop both doors, except
for double egress doors. The behavior for double egress doors can be changed (see page 77). The
sensor is not active in program mode OFF or manually opened door. In this OFF-mode the operator
fulfills the Low Energy Standards.
5.6.3 Monitored safety sensors
Both presence impulse and presence detection can be monitored. If a sensor becomes defective,
the operator will not accept any impulses if the presence detection sensor is defective. The door
remain in closed position and can be used as a manual door.
If the presence impulse sensor is defective, the door will remain in open position. Switching the
program selector to OFF will set the door control to low energy mode. Key impulse can be used as
impulse.
5.6.4 FIRE input
Ground and 24 VDC are used for supply of smoke detectors, see page 67.
Connection of fire alarm 12, 24 or 48 VDC is possible to connect to the FIRE input, see page 73 and
82.
5.6.5 Relay output
A potential free contact COM/NO/NC used in the below four different way, where the first three
are chosen by Parameter group (see ‘Relay’in table at page 77). When indicating Error or KILL, the
error relay is resting (connection COM-NC), and when indicating Door open or closed it is activated
(connection COM-NO).
•Error indication
For external error indication, see page 86.
•KILL output
Used for distribute KILL-signal to other door sets.
•Lock output
Used for control locks with other voltage than 12/24 VDC.
•Door indication (HW-wired with jumper)
Used for indicate an open or closed position of the door. The indication position is set by adjust-
ing the inhibit/blanking potentiometer. For indication of closed door, adjust the Blanking po-
tentiometer to minimum. For indication of open door, open the door by program select OPEN
or any open-impulse, and adjust the Blanking potentiometer so that the Blanking LED is lit only
in open position (or above desired position, just like blanking).
