10. Electrical Connection
General Safety Guidelines
- Place the electric switch easily accessible from the operator. If a plug contact is used in the installation the wall socket shall be placed easily accessible from the operator.
- If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
10.1 Mains Connection
- Switch off the mains.
- Assemble the bottom end plates and tighten the two screws firmly.
- Connect the plug contact to the wall socket or connect to the mains switch.
Note! The mains switch must be connected according to national regulation. - Connect the mains to the operator.
Mains Specifications: 100-240V AC – 50/60Hz

10.2 Control Units
10.2.1 CU-ESD
The CU-ESD can be equipped with extension units, EXU-SI and/or EXU-SA, depending on the functions required. (See sections below).
Terminal/Potentiometer Definitions
| Label/Function | Description |
|---|---|
| 24 V DC | Power supply output |
| GND | Ground |
| Safety Impulse | Overhead presence detection / Mat safety |
| OPD | Overhead presence detection (incl. 24V, LOUT and Safety Impulse) |
| IMP | Inner impulse |
| XIMP / IIMP | Impulse inputs (External/Internal) |
| Lock kick switch | Lock kick switch input |
| Synchronizing | Synchronizing of double doors |
Potentiometer Settings (Adjustable)
- Hold open time (1.5s - 30s)
- Closing torque
- Power assist
- Closing speed
- Opening speed
- Spring tension
DIP Switch Settings
- PUSH & GO / PULL (Arm system setting)
- Learned Button (LRN)
- Stop on stall (SOS)
- PAG (Push and Go)
- MAT (Safety mat)
10.2.2 Arm System Selection
Factory set arm configuration is PUSH. If PULL or ST is required:
- Switch power OFF
- Select arm configuration (using DIP switches)
- Switch power ON
10.2.3 Extension Units EXU-SI / EXU-SA
Installation
To extend the functions, the extension units can be mounted on top of the control unit CU-ESD, separately or combined.
Tools required: 5mm nut driver, Torx T10.
10.2.4 Extension Unit EXU-SI
Functions: This extension unit has inputs for electro-mechanical lock, program selector, batteries, KILL function, OPEN/CLOSE, KEY opening and outer impulse.
Terminal Configuration
| Terminal label | Description |
|---|---|
| +24 V DC / GND | Power Supply |
| OPEN / EXIT / OFF | Program selector inputs |
| UNL | Unlocked signal from lock |
| KRST | KILL reset |
| KILL | KILL impulse |
| KEY | KEY impulse (5s) |
| O/C | OPEN/CLOSE impulse (latching relay) |
| OIMP | Outer impulse |
| Lock | Electro-mechanical locking device (12VDC max 500mA / 24VDC max 250mA) |
Key Settings
- Battery Backup Unit: Battery monitoring.
-
Lock Functions:
- Locked without power (OFF) / with power (ON)
- Lock 12V (OFF) / 24V (ON)
- Lock kick: Position OFF (Smooth closing), Position ON (More powerful closing).
- Potentiometer: Opening delay (0s - 3s).
Notes:
- If the switch is set to ON, the LOCK RELEASE is active during the opening delay time set by the potentiometer.
- For PAIR OF DOORS installations, the LOCK RELEASE works in sequence: First the primary then the secondary.
- Lock only functions when Program Selector is in OFF or EXIT.
- If a program selector is not used, a jumper is required from position 3 to position 11.
10.2.5 Extension Unit EXU-SA
This extension unit has inputs for door mounted sensors, which can give presence impulse on approach side and/or presence detection on swing path side. Relay output for error indication or door indication is also integrated.
Functions & Terminals
| Terminal Label | Description |
|---|---|
| 1-5 (Relay) | NO/COM/NC Relay output ("External error indication" or "Open door indication") 24V, 1A. |
| QTST | Sensor monitoring |
| PDET | Presence detection (NC) |
| PIMP | Presence impulse (NC) |
| GND / 24V | Power |
Settings
- Blanking Potentiometer: Adjust to avoid presence detection sensor detecting the wall (Range 45 degrees - fully open/Max).
-
Monitoring Jumpers:
- No monitoring (both jumpers on).
- Monitoring of presence detection / presence impulse.
