Power Windows
The GWFLORID electric power window actuator consist of a motor and module. Its functions include: jam
protection, centralized control rise, soft-stop, characterized by easy control, long life, etc.
The functions of electric power window actuator
1. Jam protection
Power windows have an jam protection function when manually or automatically rising after it has been
initialized. There is no limit on the amount of jam protections. When room temperature is 25±5oC, wire
resistance 150 mΩ and 14.5 V working voltage, the jam protection force risen glass is less than 100 N. When the
window is manually or electrically rising, once it encounters a force greater than the jam protection force, the glass
will immediately stop rising and make the motor rotate in reverse. Rever\
se rotation distance is about 125 mm.
2. Centralized control rise
The central door lock controller provides four lifters with a low level signal. The power windows will close until
they are completely closed. This enables the two power window actuators to start separately, which can avoid
hitting peak currents if they start up at the same time. As long as the centralized controller's rising pin receives
the low level signal, the motor will close the window until it is comple\
tely closed.
3. Soft-stop
If the motor suffers from an impacting block when the window is rolled all the way up or all the way down, it
would shorten the power window actuator's use life. In order to avoid this, the soft-stop function must be used,
in which both manual and automatic rolling up and down should have this \
function.
(a) Soft close function:
When the window is about to get to the top, that is to say, when it's rising to the soft-stop point, the engine's
power will cut off to make the motor stop working, meanwhile the rising inertia will continue to roll the
window up to the top. The soft-stop point is about 2 mm under the top limiting position.
(b) When the window is about to lower to the bottom, that is to say, when it's lowering to the soft-stop point,
the engine's power will cut off to make it stop working, meanwhile the lowering inertia will continue to roll
the window down to the bottom. The soft-stop point is about 12 mm above the bottom limiting position.
(c) Zero position calibration: This position takes the top limiting position as the zero position. In order to
guarantee reliable and safer system operation while in use, the zero pos\
ition will need constant calibration.
Manual calibration: When the window stops at the rising soft-stop position after rising for a period,
press the rise button so it will rise to the limiting position. Zero cal\
ibration is then complete.
Automatic calibration: After the motor runs forward and reverse more than 20 times, it will undergo
zero position calibration one time. That is to say, when it completely starts or stops operating, the motor will
be blocked one time. Currently, there is no soft close or start-up function. Zero position calibration is com-
pleted when the window is completely closed to the limiting position.
4. Motor locked protection
The control module will cut off the power supply to stop the motor from working within 250 ms of the l\
ocking.
5. Motor temperature protection
When the control module is powered on, the initial temperature of the motor is set at 40oC. There are two
temperature limits for the motor's thermal protection function. If the temperature of the coil exceeds the first
temperature limit (170oC), the motor will not respond to any new operation input, but it will still complete the present
operation. If the motor's temperature exceeds the first temperature limit during its operation, it will keep working until
the temperature of the motor coil reaches the second temperature limit (190oC), then the motor will not be limited by
the second temperature's threshold while reversing, so as to guarantee the safety of the users. Once the temperature of
the motor has lowered below the temperature limit, the motor will work normally.
6. Self-diagnostic protection function
So as to guarantee the system's reliability while improving the system's average non-failure time, self-diagnostic
protection measures are used: If the power supply voltage exceeds 16 V, the control module will close the auto-
rising function.
(a) Switch contact point adhesion:
If it is detected that the switch contact point adhesion has reached up to 10 m input instructions will no
longer be received. If later the switch contact is detected to be disconnected again, it's function will return
to normal.
(b) Relay contact point adhesion:
The power window actuator is controlled by two contact point relays.
After a shutoff command is sent to one of the relays, if the system detects that this relay is still on, then
the system will choose this relay contact point for adhesion. Thereupon, the system will send out another
command to make the other electric relay switch on as well, so as to guarantee the motor's power supply is

Maintenance areas of importance
1. Initialization
Considering the system's stable and reliable operation is directly related to the state of the vehicle's door sheet
and weatherstrip, the initialization process is required at the assembly line for the overall vehicle. Continuously press
the rise button of the power window actuator to roll up the window. The window will stop rising after only rolling up
45 mm. Then, after releasing the glass switch, continuously press the rise button again. It will still only roll up 45 mm.
Basic initialization will be completed when the rise has been blocked. At this point, the system will possess all the
functions except the lowering soft-stop function. During the basic initialization rise process, there is no jam protection
function. The basic initialization is completed, and it will still have the automa\
tic lowering function.
2. Re-initialization & operating instructions are as follows
(a) This function is executable only when the following items are carried out.
• Manually correct the zero position function.
• The window rests at the mechanism dead center zero position.
(b) Within two seconds of the zero position (after the motor is blocked), release the button, then press the
button again for at least 20 s.
(c) After 20 s, the window will automatically lower about 46 mm, indicating that the characteristic curve and
zero position have been deleted.
(d) After it is deleted, the power window will only have manual function.
(e) Start initialization again.
cut off. Before sending out any new input instructions, the software will first detect whether the adhesive
contact point of the relay has been released. If it has been released, then all the operations, including the
sleep pattern, will once again be executable. If the contact point is still adhered, then only operations
going in one direction have the possibility of execution (depending on which direction the relay contact is
adhered). Then soon afterwards, activate the contact point adhesion handling funct\
ion again.
(c) Motor protection when the Hall element failed or magnetic ring damaged.
If the Hall element or magnetic ring has malfunctioned, the control module can not receive the Hall
element's signal. In this case, the control module will return to the state before basic initialization, which
means it can only rise about 45 mm at most, and it will not have the jam protection function. During
the process of a centralized control rise, re-initialization is prohibited. Once any switch is activated, the
window will stop moving.
