1.1 General Safety Information
SE Controls reserves the right to introduce any modifications
andimprovements to the contents of this publication without
the obligation of giving prior notice.
Read and observe the information contained in these safety
instructions and respect the order of procedure stated
therein.
Please keep these safety instructions for future reference and
maintenance. Reliable operation and the prevention of
damage and risks are only granted if the equipment is
assembled carefullyand the settings are carried out according
to these instructions and to the operating instructions of the
drives.
Please observe the exact terminal assignment, the minimum
and maximum power ratings (see technical data) and the
installationinstructions.
Please observe the following warning symbols
Warning!
Carefully read these warnings
Warning!
Draws attention to instructions that must be
followed in order to prevent damage to the
actuator.
Notice
Indicates important notices to which attention
must be paid.
Danger!
General danger or precautionary warning with
numerous implications
Danger!
Danger that could cause personal injury
Danger!
Danger of hands been crushed!
Danger of electric shock
1.2 Health and Safety
Personal Protective Equipment; It is recommended that
suitable PPE is worn at all times during the installation
and connection of actuator products in accordance
with a recommended safe system of work.
Handling and storage; Care must be taken in transportation to
theinstallation location and during fitting. Actuator products
must notbe dropped, impacted, allowed to get wet or abused in
any other way. Mishandling can result in serious damage.
Competence; Installation and connection must only be carried out
by authorised, competent and safety conscious persons.
1.3 Environmental
All actuator products contain metallic, plastic and
electronic parts. Redundant electronic products
are classified as hazardous waste under the
WEEE regulations (Waste Electrical and Electronic
Equipment). Electronic parts must be disposed by an
authorised and licensed recycler.
They must not be disposed of in ‘general waste’ skips.
Consult SE Controls for assistance.
1.4 Application and Use
When using the actuator, follow these safety
instructions described herein. This equipment is
designed for the automatic opening and closing of the
stated types of windows.
For further application, please contact SE Controls.
The actuator compiles with current safety directives.
Operating safety can be guaranteed only if installers comply with
the safety regulations in force in the country where the actuator
is used.
Do not install two or more actuators on the same
window without using a synchronisation accessory.
Any other application of the actuator must be
approved after technical testing of the application.Use
only original accessories or accessories approved by SE
Controls to install the actuator.
The actuator is not a structural member of the window. Always
mount the safety arms in bottom-hung applications. The position
of the three-way switch button must be outside the field of action
of the moving part of the window.
Do not allow children to play with the fixed or remote controls.
When opening or closing the window, make sure
other people are far away from the moving part,
even when a fire detection system is closing an open
window.
It would be beyond the scope of these safety instructions to list all
the valid regulations and guidelines.
Always make sure that your system corresponds to
the valid regulations. Pay particular attention to: the
aperture cross-section of the window, the opening
time and opening speed, the temperature resistance
of the cables and equipment, cross-sections of the
cables in relation to the cable lengths and power
consumption.

Care must be taken to ensure that actuator products
are controlled with compatible products; refer to
SE Controls. No liability will be accepted and no
guarantee nor service is granted if actuator controls
are used without such compatibility being confirmed.
1.5 Installation
Warning! Incorrect installation may render the
actuator dangerous! Follow all the instructions set out
below and the instructions applied to the motor.
Installation of this equipment must only be carried out by
authorised, competent and safety conscious persons.
The actuator must be assembled and connected only
by specialised staff who have been properly trained
and who are familiar with the problems associated
with automatic window opening and closing systems,
technical reference standards and safety standards.
The window closes automatically. When opening and
closing, the drive unit is stopped by the power cut-
off. The corresponding pressure force is listed in the
technical data.
Take care - the pressure force is high enough to cause
injury!
During assembly and operation do not obstruct the
window opening!
Danger of crushing/trapping!
Routing of cables and electrical connections only to be done by a
qualified electrician.
Power supply leads 230 V AC to be fused separately
by the customer. Keep power supply leads sheathed
until the mains terminal.
All low voltage cables (24 V DC) to be installed
separately from high voltage cables. Flexible cables
should not be plastered in. Provide strain relief for
freely suspended cables.
The cables must be installed in such a way that they cannot be
severed off, twisted or bent off during operation.
Junction boxes must be accessible for maintenance work.
Adhere to the type of cables, cable lengths and cross-
sections as stated in the technical information.
After installation and any changes to the system check all
functions by a trial run.
1.6 Maintenance
Always disconnect the motor’s supply voltage and batteries during
cleaning or maintenance operations, especially if the actuator is
equipped with an automatic control device.
The system must be protected against unintentional
re-starting.
All smoke ventilation systems must be periodically
(annually) checked, serviced, maintained and, if
necessary, repaired and re tested by a authorised,
trained and competent, safety conscious persons.
Maintenance shall be carried out in accordance with the
requirements of;
•
Building regulations 2002
•
Health and Safety at Work Act 1974
•
I.E.E Regulations
•
Regulatory Reform (Fire Safety) Order 2005
In order to keep the equipment in optimum operating condition it
is recommended that ventilation systems are similarly maintained.
There are no user repairable parts in this equipment.
Basic checks that can be carried out include;
•
At least once a year, check that the power
cable and connection has not been damaged
and that it shows no sign of wear
• Check that no object obstructs
the window movement.
• If faults arise, never work on the actuator and
never open or dismantle parts of the actuator that
deny access to the inside of the mechanism.
•
If the actuator fails to function or is
damaged, contact SE Controls.
•Do not use the actuator until it has been repaired.
A suitable service contract with SE Controls is recommended for
this purpose.
The gear system is greased for life and is maintenance free.
Defective equipment must only be repaired by SE
Controls. Only original spare parts are to be used.
After maintenance, repair or any changes to the system check all
functions by a trial run.

A: Bottom hung window installation
The installation process is similar to the above (Top hung window installation)
Caution: Safety arms chains are recommended to connect to the frame for moving part of the window if bottom hung widows are
installed.
B: Top hung window installation
i. Fix the trunnion set(2) in the mid position on the moving part of the window using the holding bracket (4) provided.
ii. Close the window, then fix the chain actuator body(1) with the pivot bracket set(3) provided. It should be aligned with the trunnion
set(2) on the moving part of the window. Caution: misalignment will cause improper opening and closing of the window.
iii. Fix all screws in the trunnion set(2) and pivot bracket(3) firmly. (Make sure sufficient space is allowed for the actuator body to
rotate)
iv. Fix the pin to connect the trunnion set(2) to the top part of the chain.
v. Switch on the power supply to test run the actuator for a few cycles, make sure the opening and closing of the window is smooth
and free from obstruction.
vi. Repeat the above if adjustment is required.

Setting the zero position of the actuator (For optimum performance ensure zero point is correctly set)
I. With the actuator fitted to the vent, run the motor to open and then commence the close of the motor .
II. Position the Zero Set Tools (ZST’s) as shown whilst the motor is running.
III. Still holding the ZST in place, allow the vent to close until it stops on current limit MAKING SURE YOU DO NOT TRAP YOUR
FINGERS.
IV. New zero point is now set. Power and ZST can be removed.
