Reinstatement

I nertia safety brakes IB/95-17, IB/147, IB/147W are designed to

prevent sharp descent of the rolling shutter, thus adding to the safety

and security of rolling systems with heavy shutter weight.

In the event of failure of the gearing mechanism of the tubular motor, the

rolling shutter drops down sharply, whereby the rotation speed of the roll

tube exceeds 22 revolutions per minute, which causes the safety brake to

operate - the drive shaft gets locked and the shutter stops.

The inertia safety brake is a safety device in accordance with EN12605. The

installation of a safety brake on garage doors for private, commercial or

industrial purposes allows them to comply with the requirements of EN12604.

2. SELECTION

In order to select the most suitable model of safety brake, it is important to

secure the safe mode of safety brake operation:

Nominal torque: is the value of the motor's torque for which the use of the

selected model of safety brake is appropriate (see the selection table). Please

make sure that the motor's torque does not exceed the nominal torque of the

safety brake.

Maximum locking torque: is the maximum torque accepted by the safety

brake when it blocks the rotation of the roll tube in the case of a fault.

Working speed: is the maximum number of revolutions per minute at

which the safety brake works as a simple support without functioning as a

descent stopper. The rotation speed of the roll tube of the rolling system must

be within this value.

3. INSTALLATION INSTRUCTIONS

Connection, installation and commissioning should be carried out by

quali ed personnel in accordance with the regulations of the region where

the installation is being performed.

Safety brake is installed on the end cap, console or carriage on the side

opposite to the motor. The brake acts as a bearing support, therefore

installation of a separate bearing support is not required. It is necessary to use

fastening screws with a minimum strength class of 8.8.

Important! The safety brake must be positioned strictly horizontally

and vertically on its base, with the locking screw located at the bottom.

Incorrect installation may trigger false braking.

Please make sure that the limit switch is operational. The limit switch must

be screwed into the safety brake housing, whereby there should be no gap

between the switch and the housing.

The limit switch must be electrically connected so that when it is triggered,

the drive is disconnected (see the proposed wiring diagram). In control units,

the switch must be connected to a safety circuit (emergency stop circuit) in

order to cut the control current of the motor during an emergency drop of the

rolling shutter.

If the power cable is damaged, it must be replaced by the manufacturer or

an authorised technical service centre in order to avoid all risk. Damaged cable

must be recycled.

It is not allowed to make unauthorized changes to the product or use

it for other purposes.

4. TESTING INSTRUCTIONS

The testing process of the safety brake consists of the following steps:

1. Ensure that all fastening screws of the safety brake are tted with suitable

washers (preferably self-locking washers) and perfectly tightened.

2. Since it is impossible to simulate a breakdown of the motor, you can

make sure that the safety brake is operational by listening to the sound caused

by the movement of internal components. If the rotation of the internal

components is clearly audible without jamming and there is no intermittent

movement of the rolling shutter, then the safety brake is operational.

3. If the safety brake is equipped with a limit switch, make sure that it is

connected.

4. Make sure that the safety brake is duly protected from excessive harsh

conditions such as dust, water, etc.

5. If there is a chain transmission in the rolling system, it is necessary to

ensure that the chain is not loose. Insuﬃcient chain tension causes sharp

accelerations that can trigger the safety brake to block.

5.REINSTANTEMENT

Inertia safety brakes, as safety devices, can stop the rotation of the roll tube

more than once to prevent dangerous acceleration of the rolling shutter, but

each time after that they must be reinstated. A total of 10 automatic brake

stops are allowed.

To reinstate the brake to its original working state, it is necessary to loosen

IB147W

the locking screw, turn the central part to its original position so that the arrow

on the central part is strictly vertical. After that, the locking screw must be

130

tightened with a torque wrench (clamping force applied should be according

380

to the table for this version of the brake). It is necessary to apply paint (varnish)

on the locking screw to prevent its loosening.

6.OPERATION

If the installation procedure has been respected, the safety brake does not

require any maintenance.

Safety brake must not be oiled under any circumstances!

PROHIBITION! Children and individuals with reduced emotional

and/or mental abilities as well as individuals with signi cantly reduced

physical abilities should refrain from using brake for safety reasons. The use of

receiver is prohibited for individuals who do not have relevant user

experience, skills and/or technical knowledge.

Keep children away from brake and relevant control devices and electric

appliances at all times to avoid injuries and damages.

Please, contact your nearest roller shutter service center or roller shutter

systems supplier for any operation inquiries that were not clari ed within this

publication.
