The swing door operator ASSA ABLOY SW100 uses a DC motor and a gear-reduction system to drive an arm system, which opens the door. Closing power is provided by a motor and a clock spring. An electronic control unit uses a motor encoder and a microprocessor to control the door’s movement.
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.
5.3 Functions on the Basic Control Unit CU-ESD
Also see page 44 for more information.
5.3.1 Power failure
During power failure the operator acts as a door closer with controlled closing speed.
5.3.2 Spring force
The operator is delivered with spring pre-tension factory set to 210°. If necessary, the spring tension can be electronically adjusted with a potentiometer to required closing force.
5.3.3 Extended closing force/torque (CLTQ)
If the potentiometer CLTQ is set to 0°, the door will close with normal spring power. If the potentiometer is turned clockwise, the motor will increase the closing force/torque.
5.3.4 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.
5.3.5 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 program selector setting OFF.
5.3.6 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 is not active during opening and closing. Lock-out signal must be connected 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).
5.3.7 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).
5.4 Functions on the Extension Unit EXU-SI
Also see page 46 for more information.
5.4.1 KILL function
- If KILL circuit is closed, the control will ignore all signals and close door(s) at normal speed.
- When KILL is no longer active, operator will resume normal operation.
- If KILL function must have manual reset, jumper must be removed and reset button connected to terminal No. 8 and Ground.
- The lock will lock when KILL is active regardless of program selector setting.
- The function of the lock can be changed during KILL (see page 58).
- In a double door application, KILL is only connected to the primary operator.
5.4.2 Function of locks
- The lock output is short circuit proof and can source a lock with 12 V DC, max. 500 mA or 24 V DC, max 250 mA. Lock function is active in program selection EXIT and OFF.
- DIP-switch to select 12 or 24 V DC.
- DIP-switch to select locked with or without power.
- DIP-switch for lock release and potentiometer for opening delay.
- DIP-switch for lock kick if door is not fully closed, to overcome binding in the locking device during closing.
- 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 output signal shall be active low.
5.4.3 Program selector
- Input for OPEN, EXIT and OFF (if no program selector, AUTO is default).
5.4.4 Impulses
- Input for OUTER impulse, KEY impulse and OPEN/CLOSE impulse.
5.4.5 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 parameters, see page 58.
OPEN/CLOSE impulse works only in program selection ON.
5.4.6 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 CU-ESD. If selected the relay on EXU-SA can give a contact information. An audible warning signal can be achieved by using the accessory board AIU. It is connected to the 24 V DC and plugged into the EXU-SA relay output terminal.
- During POWER FAILURE the operator will finish the actual operating cycle and then switch off 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 58. 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 swing path, door mounted
Note! All sensors works normally in CONVENIENCE MODE.
5.4.7 Nurse and bed functionality
Solution 1
- Connect a bridge between 3 and 7 on the secondary EXU-SI.
- 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 EXU-SI.
- 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 EXU-SI.
- 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 EXU-SI.
- 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.
5.5 Functions on the Extension Unit EXU-SA – optional
Also see page 47 for more information.
5.5.1 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).
5.5.2 Presence detection swing path, 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 58). The sensor is not active in program mode OFF, manually opened door or during battery operation.
5.5.3 Monitored safety sensors
Both presence impulse and presence detection can be monitored. If a sensor becomes defective, the operator will not accept any impulses and will then work as a manual door closer.
5.5.4 Open door indication
A relay output is used to indicate an opening cycle or a specific position of the door. The indication position is set by adjusting the inhibit/blanking potentiometer.
5.5.5 Error indication
A potential free contact COM/NO/NC for external error indication, see page 66.
