1. Introduction
KM-10 controller is an “intelligent” door control board designed for automatic telescopic lift doors with 24VDC reduction
gear motor. It provides advance features for high comfort, high dynamic performance and flexible usage.
• KM-10 provides complete hold of the motor with its 4-region motor control and high-resolution encoder input hardware.
• In addition to this hardware, it allows swift but comfortable motion of doors with its software that provides S-softening
in travel ramps and which has the algorithm that does not require limit switches.
• It provides features for auto-learning of door travel limits without open-close limit switches.
• In order to work with the control panels in complete harmony it can generate “Doors are completely open”, “Doors are
fully closed” and “Obstruction or photocell detected” signals.
• Compatible with fire lift doors.
• A nudging function is included with buzzer sound and slow speed closing after a long-time photocell interrupt.
• In case of mains failure, it can get the power from batteries or 24VDC external supply.
• It provides a parameter menu which has access levels for security, user/customer needs and easy adjustment.
• It provides many functions and parameters for manufacturing companies that enable application flexibility, like motor
reduction ratio, motor revolution, motor sheave circumference and skate open zone.
• It provides user friendly parameter setting with speed units in cm/s and travel distance units in cm.
• It provides a counter for the information of opening-closing times.
• Internal keypad and display allows access to all its parameters, functionality and monitoring screens.
• Availability of multiple languages: Turkish, English, Greek, Russian, French and Italian.

2. General Warnings
• The ac power supply voltage must be between 18V-22Vac. Supplies over 22Vac may be hazardous for the controller.
• The power of input supply transformer must be minimum 10VA more than the motor power.
• Door motor must be 24VDC reduction gear motor and maximum motor power must be 200W.
• 100-2048 pulse incremental encoders are supported. Encoder must have 2 channel output (A and B) and the operating
voltage must be 5Vdc. Encoders with higher resolutions provides more accurate measurements and improves motor
ascendancy.
• According to the EN81, door movement must be prevented when emergency stop, inspection or recall modes engaged.
Door operation with a single command can only be used for old door units.
• According to EN 81, the maximum static closing force must not exceed 150N. Higher static closing forces may cause
serious injuries.
• According to EN81, the maximum kinetic energy of the door in closing direction must not exceed 10J and for nudging
closing (Reduced speed closing) the maximum kinetic energy must not exceed 4J.
• The voltage applied to inputs of the door controller must not exceed 28Vdc.
• The relay output contacts of the door controller must not be used as safety circuit contact in the safety circuit of the

The type of door speed settings. All speed parameters can easily be set to default values
or can be adjusted separately. The speed setting parameters only appear when this
parameter is set to “CUSTOM SETINGS”. Otherwise these parameters will be set to
default values and will not appear in menu.
These speed setting parameters are:
• OPENING SPEED
SPEED SETTINGS • OPENING SLOW SPD
• OPEN RAMP LENGHT
• OPEN SLOW AREA
• CLOSING SPEED
• CLOSING SLOW SPD
• CLS.RAMP LENGHT
• CLOSE SLOW AREA
KM-10 User Manual V1.10

SLOW DEFAULTS Speed setting parameters will be set to slow default values.
NORMAL DEFAULTS Speed setting parameters will set to normal default values.
FAST DEFAULTS Speed setting parameters will set to fast default values.
CUSTOM SETINGS Each speed setting parameter can be adjusted separately.
The holding force constantly applied to motor after door fully opens to remain door open
OPEN HOLD FORCE
(To overcome the closing force because of the door spring)
The holding force constantly applied to motor after door fully closes to remain door closed
CLOSE HOLD FORCE
(To overcome the opening force because of the skate spring)
The maximum opening-closing force applied to overcome an obstacle
If an obstacle is detected in the closing operation, door stops, gives a warning to lift
controller by activating the obstruction relay output (R3) and fully opens. Then obstruction
relay is deactivated. After the “close signal” is given by the controller door tries to close
again with normal travel speed up to the obstacle. Then it decelerates near the obstacle. If
door overcomes the obstacle it continues the rest of the way at normal closing speed. This
action is repeated continuously for as long as the obstacle remains.
OBSTRUCTION PRS.
If an obstacle is detected in the opening operation, door stops. Obstruction relay (R3)
remains deactivated. Door remains in this position and waits “close signal” from lift
controller for 15 seconds. If no close signal is given after this waiting period door tries to
reopen with normal travel speed up to the obstacle. Then it decelerates near the obstacle.
If door overcomes the obstacle it continues the rest of the way at normal opening speed.
This action is repeated continuously for as long as the obstacle remains.
Note: According to EN81, the maximum static closing force must not exceed 150N.
POWER_ON_CLOSE Some door controller does not activate door commands unless safety circuit reading during
first time energized.
DISABLED Elevator Controller decides door opens or closes during first time energized.
ENABLED KM-10 starts closing door without waiting for any command during first time energized.
PTC CONTROL FSL input can be programmed to monitor motor PTC.
DISABLED FSL input is used to monitor photocell.
ENABLED FSL input is used to monitor motor PTC. If signal on the FSL input is interrupted KM-10
gives PTC error.
LEARNING SPEED Door auto-learning speed during the measurement of the door travel length.
DEMO MODE Door test operation
Door is in test operation. Door opens and closes continuously with a few seconds intervals,
ENABLED the control signals (Open, close etc.) will be ignored. The reopening signals (Photocell or
obstacle detection) are still functional.
DISABLED Door is in normal operation.
SIGNAL TYPE The type of door control signals
KM-10 will be controlled by two separate inputs. 24Vdc voltage applied to terminal
“Close” will cause the doors to close. And terminal “Open” will cause the door to open. If
OPEN/CLOSE SNGL.
no signal is applied the door remains its position. If both inputs are applied the close signal
has priority.
KM-10 will be controlled by a single input. Only “Close” signal is used and “Open” signal
is not used. 24Vdc voltage applied to terminal “Close” will cause the doors to close.
Interrupting the voltage causes the door to open. During the absence of voltage, the door
CLOSE SIGNAL
remains open.
Note: According to the EN81 door movement must be prevented when emergency stop,
inspection or recall modes engaged. This adjustment can only made for old door units.
COUNT CLEAR CODE The security code used for clearing the opening/closing counter. The count clear code
(Max. 4-digit) can be set by using up and down buttons. It requires to exit menu after
setting the security code. If the code entered is correct, the open/close counter will be
cleared after the menu is closed.

CLOSE SLOW AREA The closing distance with slow speed up to the closing rubber stopper
SKATE CLS. SPEED Skate closing speed
SKATE ZONE The distance that is required for skate to fully closed

Figure 16 Door closing travel curve

12.4. Max. Door Closing Speed

According to EN81, the maximum kinetic energy of the door in the closing direction must not exceed 10J. And for nudging
closing (Reduced speed closing) the max. kinetic energy must not exceed 4J. This can be calculated by the formula:
Maximum kinetic energy = (1/2) x Km x (Vmax^2)
Km: Total door panel weight (kg)
Vmax: Maximum speed of the door (m/s)
An example for a calculation of maximum speed: Km = 120 kg
The maximum closing speed Vmax (Normal) = 0,4 m/s and The maximum nudging speed Vmax (Nudging) = 0,25 m/s

Gear ratio: 15:1 GEAR RATIO 2 = 3000/15 = 200

GEAR RATIO 2 = 200

GEAR RATIO 1 = 3000

12.6. Pi Speed Regulator Adjustment

SPEED CONT. KP The differential factor of PI speed regulator
SPEED CONT. KI The integral factor of PI speed regulator
“SPEED CONT. KP” and “SPEED CONT. KI” parameters determine the PI speed regulator’s reaction sensitivity which adjusts
the motor speed.
The integral factor KI multiplies the total of errors so must be adjusted to very smaller than KP otherwise it causes vibration and
overshoots at travel curve. Usually it is better to adjust KP > 10xKI.
If KI and KP are too high it makes noise at motor. Too small values cause delays to catch the reference speed and sensitivity
loss.

13. Emergency Operation

For emergency operation, serially connected two 12V battery (Dry-acid) can be connected to the AKU+ and AKU- terminals. In
normal operation the batteries will be kept as charged. If the power supply energy cut off, the KM10 will continue to its normal
operation. However, if the batteries discharge operation will be stop. This is a point should be taken into account while
installation.

14. Nudging Operation

If NDG signal is active (In a fire alarm state), nudging operation is activated. In this operation door should be closed as soon as
possible. To prevent injury of people who can be present between the doors, doors are tried to close very slowly even the FSL
signal is broken. While this operation audible alarm is generated.

17. Troubleshooting
DOOR DOES NOT MOVE
• Check the power led 24V on the board. If 24V led is OFF check the ac power supply and the ac supply fuse on the left
side of the board.
• Check the motor power connection on terminals MOT.
• Check the parameter “SIGNAL TYPE” (Parameter  on digital display). When this parameter is set to “OPEN/CLOSE
SNGL.” door will not move until a command is given from terminals OPEN or CLOSE. Check these input leds. In
order to test these inputs, disconnect the wiring of OPEN and CLOSE terminals. Then test these inputs by making a
bridge between terminals: GND > COM, 24V > OPEN and 24V > CLOSE.
• Check that door is not mechanically blocked
DOOR PANELS ARE OPENING-CLOSING RAPIDLY AND UNCONTROLLABLY
• Check motor and encoder wirings. When you move the door manually the speed of door must be shown on display.
• Encoder channel-A and channel-B connection may be wrong. Interchange these inputs.
DOOR DOES NOT OPEN
• When door open signal is activated OPEN led on board must be ON. If OPEN led is OFF be sure that lift controller
gives open command.
• Check that the CLOSE led is OFF. If close signal is active door does not open because close signal has priority.
• If the parameter “SIGNAL TYPE” (Parameter on digital display) is set to “CLOSE SIGNAL” check that close
signal is not active.
• Check that door is not mechanically blocked.
DOOR DOES NOT CLOSE
• When door close signal is activated CLOSE led on board must be ON. If CLOSE led is OFF be sure that lift controller
gives close command.
• Check that door is not mechanically blocked.
DOOR MOVES IN REVERSE DIRECTION
• Door connection may be wrong. Interchange the motor power outputs and at the same time interchange the encoder
channels A and B.
DOOR HITS or DOOR DECELERATES EARLY
• Be sure that the auto-learning operation is done properly
• Check that door speed setting are adjusted correctly
KM-10 User Manual V1.10

DOOR OFTEN DETECTS OBSTACLE

• Check that door has no mechanical defect.
• Check that obstruction pressure is not too low.
• Check that encoder is not faulty.
• Check that Ac power supply is not too low
DOOR PANELS ARE VIBRATING
• Check that the encoder is connected correctly.
• Check the PI speed regulator settings (SPEED CONT. KP and SPEED CONT. KI)
• Check that door has no mechanical defect.
DOOR FULLY OPENS THEN IT MOVES 1-2cm BACK AND TRIES TO OPEN AGAIN
• Door open hold force may be too low and door cannot overcome the closing force because of the door spring.
• At that floor, landing door spring may be too strong.
DOOR MOTOR and DRIVE CIRCUIT IS HEATING UP EVEN DOOR STOPS
• Check that the opening and closing hold force are not too high.
