The motor is only to be used for specific purpose and elevator systems in which
the producer was informed during order placement.
The motor is only to be operated according to the specifications on the
identification label.
2.4. Primary Safety Instructions
The motor has a casted lifting ring. This ring has been designed to carry only the motor with its brake and sheave. Do not load any other components, e.g. ropes, sockets etc., on the motor.
When the motor shaft is turning, voltage will be induced and applied to the motor terminal!
The motor is only to be used with a screened power cable which also contains a grounding conductor. Please make sure that grounding of the screened power cable is performed separately from the grounding connection of the building.
U, V, W phase conductors of power cable should be connected to the connection box terminals in the same order of auto-tuning realization.
The motor does not generate any torque when the motor current is cut off. In this situation, if the brakes are opened, the cabin will accelerate out of control. Thus, it is highly recommended to short-circuit the motor windings during the installation of the elevator system.
This will lead to the speed depending braking torque which is similar to the friction in traction machine-motor system. The short-circuit has to be made by main contacts of the contactors. Short-circuiting of the windings can only be made when the motor wires do not carry any current.
Safety components which are monitoring brake releases, e.g. micro-switches, should not be demounted or deactivated.

•Electromagnetic brakes should be connected in accordance with the specifications on the brake label and the brake connection diagram given in Figure 3. (for SMT 200 AC and SMT 225) and Figure 4 (for SMT 140 AC).
•Electromagnetic brakes are designed for static braking applications. Brake pad/lining wear can be kept at its minimum level when the brake is only used for static applications. Therefore, generally the break does not require maintenance.
•Dynamic applications are limited to only test braking and emergency braking by the manufacturer.
•In case of power cut-off/blackout, it is not possible to release the brakes manually/mechanically. The brakes can be release with the help of a power supply. (e.g. UPS, battery)
•The brakes are securely protected against overvoltage, resulting from switching, by varistors. Brakes are supplied with factory-mounted varistors in the terminal box.
•Brake release control should be performed via micro-switch mounted on the brake. Otherwise, the brake will be no longer under warranty.
CE certificated AKAR Electromagnetic Disc Brakes provide maximum security
and are approved as a safety device for ascending car overspeed protection.
Therefore, there is no need to use bi-directional safety gear according to EN
81-1:1998+A3:2009. One-direction operated safety gear is sufficient.

Micro-switches are used to monitor the instantaneous situation of
the brakes. Depends on the signal coming from micro-switches,
inverter decides if the system should run or not.
If the signal confirms that the brake is released successfully, inverter
will let the system run. Otherwise, if the brake cannot be released
successfully, inverter will stop the system. Therefore, the motor
cannot draw more than its nominal current to overcome the break
torque. Consequently, both inverter and the motor are protected
against overvoltage.
It is recommended to use two contactors (on AC side and DC side)
for brake switching. During normal operation, AC-side contactor
should be switched by the brake relay. It will help reducing the
mechanical noise.
On the other hand, DC-side contactor should be switched by the
motor contactors. This will lead to a quick respond and fast closing
of the brake in case of an emergency stop.

If a lower voltage value than the operating voltage is applied, the
brake will not be working properly. Friction noise may occur, motor
may draw greater current and overheat or inverter may give error.
If a higher voltage value than the operating voltage is applied, the
brake will be overheating in a short time.

6.3. EN 81-1:1998+A3:2009 Brake Tests
Please acknowledge that the given checklist might not be covering
all the possibilities. Additional tests or controls may be required.
Therefore, commissioning and start-up should be done by
authorized and trained personnel who have knowledge and
experience in commissioning and start-up.
Before starting the test, please make sure that the short-circuit of
the motor is disabled. Thus, only the effect of the brake can be
tested without motor blockage.
It is recommended to perform the test at the midpoint of the
hoistway.
6.3.1. Overload Test
The test should be performed while the car is descending at the nominal speed
with the 125% of nominal load stated on the motor label. Supply of the motor
and the brake should be cut-off.
K-75.04; 31/01/2013; 1/01 Page 24 / 42
Operation and Maintenance Manual– SMT Series SMT 140AC/ SMT 200AC/ SMT225
6.3.2. One Brake Failure Test (only for Double Brake)
In case of the motor is supplied with double brake, the test should be
performed while the car is descending at the nominal speed with the nominal
load stated on the motor label. Supply of the motor and the brake should be
cut-off.
Remark 1: While the test is being performed, one of the brakes should be
released all the time during the test. The other one should be operated and
tested independently.
Remark 2: While the test is being performed, the elevator system should be
observed carefully. If no deceleration is observed, released break should be
closed immediately.
For permanent magnet synchronous motors, the effort required to
move the cabin upwards with its nominal load exceeds 400N.
Therefore, it is compulsory to accommodate a means of emergency
electrical operation in accordance with 14.2.1.4. (EN 81-
1:1998+A3:2009 2.5.2) Item 1
6.3.3. Micro-Switch Test
Micro-switches should be tested independent of the brakes. Micro-switch
should be open or closed instantly depending on the usage in the security
circuit. In case of incorrect or unexpected signal of the micro-switch,
operation should not be initiated.
6.4. Emergency Operations
Emergency operation is only to be performed by authorized and trained
6.4.1. Emergency Electrical Operation
Emergency operation should be performed with a means of emergency
electrical operation (see above) and this means shall be located in the relevant
machinery space:- Machine room (6.3),
- Machinery cabinet (6.5.2) or
- On the emergency and tests panel(s) (6.6).

Operation and Maintenance Manual– SMT Series SMT 140AC/ SMT 200AC/ SMT225
6.4.2. Emergency Mechanical Operation (by Brake Releasing)
Mechanical emergency operation shall be performed if and only if there is no
other option is left for emergency rescue (e.g. brake burning).
In order to prevent the cabin from accelerating out of control, it is
highly recommended to short-circuit the motor windings.
This will lead to the speed depending braking torque which is similar
to the friction in traction machine-motor system. The short-circuit
has to be made by main contacts of the contactors. Short-circuiting
of the windings can only be made when the motor wires do not
carry any current.
Emergency mechanical operation is only to be performed by authorized and
trained personnel by following the safety instructions below:
• Emergency mechanical operation shall be performed by using
the brake releasing device.
•Make sure that the short-circuiting of the motor windings is
made. (Short-circuiting is important to prevent the motor shaft to
be loosened. Otherwise, due to the loose motor shaft, cabin will
accelerate out of control in the direction of heavy side of the
system. )
•This will lead to the speed depending braking torque and the
cabin will move with a constant speed in the direction of the
heavy side of the system.
•Close the brake in order to stop the system when it is necessary.
•Brake releasing device should be kept in a safe place so that
unauthorized person will not be able to reach it.
AKAR takes no responsibility of inappropriate use of brake
releasing device.

Operation and Maintenance Manual– SMT Series SMT 140AC/ SMT 200AC/ SMT225
6.4.3. Power Failure Operation
In case of a power failure, the Power Failure Operation is used to evacuate the
cabin by bringing the cabin in an appropriate floor level when the cabin cannot
reach to a floor level in the hoistway. This operation should be supplied with an
uninterruptible power supply (UPS) in the control panel.
Power Failure Operation and the other Emergency Operations
operate separately and cannot be substitutes for each other.
