Overview
After installing a shutter motor, calibration must be performed.
Calibration is required because the device must learn how the motor moves. It measures the full travel time between the open and closed end positions.
This allows the shutter device to control the motor correctly and use position values such as 0%, 50%, and 100%.
The guide for the Wave Shutter calibration is found here.
Why calibration is required
Calibration allows the device to:
Learn the motor run times
Detect the open and closed end positions
Enable percentage positioning
Improve obstacle detection
Store the correct travel time for future operation
Without calibration:
Position control may fail
The motor direction may behave incorrectly
Percentage control may not work correctly
The shutter may not stop at the correct position
How shutter calibration works
When calibration starts, the shutter device first moves the motor up to the open position. After that, the device starts the main calibration process.
The calibration sequence works like this:
The shutter moves the motor up to the open position.
The shutter starts moving the motor down to the closed position.
While moving down, the device measures the motor run time.
When the lower limit is reached, the motor limit switch disconnects the motor power.
The device detects the power drop and stops measuring the down movement time.
The shutter then moves the motor in the opposite direction.
While moving up, the device measures the motor run time again.
When the upper limit is reached, the limit switch disconnects the motor power.
The device detects the power drop and stops measuring the up movement time.
The device saves the measured motor run times.
After successful calibration, the shutter moves to 50%.
When the shutter moves to 50%, this means that the calibration finished successfully. During calibration, the blind moves up, down, up, and then down to 50%. During the calibration procedure, the yellow LED is blinking.
Steps before starting calibration
Before starting shutter calibration, complete the checks below.
1. Verify the wiring diagram
Always check the correct wiring diagram before powering the device.
Make sure that:
The shutter device is wired according to the correct diagram.
The motor open and close wires are connected to the correct outputs.
The power supply is connected correctly.
The device is suitable for the used motor type.
Incorrect wiring can cause wrong direction, failed calibration, or device protection.
2. Check the neutral connection
Use the correct neutral connection.
A missing or wrong neutral connection can cause unstable motor operation. It can also prevent the device from detecting motor power correctly.
3. Check the motor rating
Before calibration, check that the motor rating is supported by the shutter device.
Check:
Motor voltage
Motor power
Motor current
Motor type
Manufacturer specifications
A motor that is too large or too strong may behave differently. It may also trigger protection or cause calibration errors.
⚠️4. Set the motor end limits before adding the shutter⚠️
Before connecting the shutter device for calibration, set the motor end limits directly on the motor. The end limits define the fully open and fully closed positions. This is important because the shutter device uses the motor limit switches during calibration. When the end position is reached, the limit switch disconnects the motor power. The device detects this power drop and uses it to stop measuring the travel time.
5. Verify motor direction
Before calibration, confirm that the motor moves in the correct direction.
Check that:
The open command moves the shutter up.
The close command moves the shutter down.
If the direction is reversed, check the motor wiring and correct it before calibration.
Note: The below steps are optional by default a normal roller should work in case you have blinds or any issues during calibration review the following parameters.
6. Confirm the shutter operating mode
Check the shutter operating mode before calibration.
Use Parameter No. 71 – Shutter operating modes.
Available values:
| Value | Mode |
|---|---|
| 0 | Shutter with positioning |
| 1 | Venetian blind with positioning |
| 2 | Manual time set, no end switches |
Default value: 0
Use 0 – Shutter with positioning for standard roller shutters.
Use 1 – Venetian blind with positioning when slat tilt control is required.
Use 2 – Manual time set only when no end switches are used.
7. Check venetian blind parameters, if used
If Parameter No. 71 is set to 1 – Venetian blind with positioning, check the venetian blind parameters before calibration.
Parameter No. 72 – Venetian blind time of full slat turn
This parameter sets the time needed for a full turn cycle of the slats.
Default value: 150
Value range:
| Value | Description |
|---|---|
| 0–65535 | 0–655.35 seconds, in 0.01 second steps |
Parameter No. 73 – Set slats back to previous position
This parameter defines if the slats return to the previous position after some operations.
Default value: 1
Available values:
| Value | Description |
|---|---|
| 0 | Disabled |
| 1 | Slats return to the previously set position |
This can apply after gateway operation, momentary switch operation, reaching a limit switch, or receiving a stop command.
8. Check motor operation detection
Use Parameter No. 76 – Shutter Motor operation detection.
This parameter defines how the device detects that a limit switch has been reached.
Default value: 1
Available values:
| Value | Description |
|---|---|
| 0 | Disabled. Limit switch detection is not used |
| 1 | Auto power calibration |
| 2–255 | Power threshold in watts |
For normal calibration, the recommended value is usually 1 – Auto power calibration.
If this parameter is disabled, the device may not detect the end limit correctly.
9. Check the delay between motor movements
Use Parameter No. 77 – Shutter Time delay for next motor movement.
This parameter defines the minimum time between motor movements. It prevents the motor from being switched off and on again too quickly.
Default value: 5
Value range:
| Value | Description |
|---|---|
| 1–255 | 0.1 seconds to 25.5 seconds |
Resolution: 100 ms
10. Check the motor power consumption delay
Use Parameter No. 79 – Shutter power consumption max. delay time.
This parameter defines the maximum time before the device reads motor power consumption after a relay is switched on.
If no power consumption is detected within this time, the relay switches off.
This can happen if:
The motor is not connected
The motor is damaged
The motor needs more time to start
The motor is already at the end position
Default value: 30
Available values:
| Value | Description |
|---|---|
| 0 | Time is set automatically |
| 3–50 | 0.3 seconds to 5 seconds |
Resolution: 100 ms
11. Check the stop delay after reaching the end switch
Use Parameter No. 80 – Shutter delay motor stop after reaching the end switch.
This parameter defines the time after which the motor stops after the end switch contacts are closed.
It can help with motors that have soft start behavior.
Default value: 10
Value range:
| Value | Description |
|---|---|
| 0–255 | 0 to 25.5 seconds |
12. Start forced calibration
Use Parameter No. 78 – Forced shutter calibration to start calibration.
Available values:
| Value | Description |
|---|---|
| 1 | Start calibration |
| 2 | Device is calibrated, read only |
| 3 | Device is not calibrated, read only |
| 4 | Calibration error, read only |
Default value after factory reset: 3
To start calibration, set the parameter value to 1.
After calibration:
Value 2 means the device is calibrated.
Value 4 means calibration failed.
Motor differences matter
When troubleshooting shutter calibration, compare the affected motor with other working motors.
Important motor differences include:
Motor size
Motor power
Manufacturer
Current draw
Start behavior
End limit behavior
A larger or stronger motor may behave differently from smaller motors. It can also trigger device protection or cause calibration problems.
⚠️Important note about motors with extra electronics⚠️
The shutter device is designed to be connected directly to the motor. If the motor has extra electronics, such as a built-in remote control module, it may not work correctly with the shutter device. This is because the extra electronics can prevent the device from measuring the motor power correctly. If the device cannot measure the power correctly, it may not detect the end limit of the connected roller shutter, slat blind, or curtain. For correct calibration, the device must be able to detect the power drop when the motor limit switch disconnects the power.
Recommended installation best practices
Before calibration:
Verify the wiring diagram.
Use the correct neutral connection.
Check the motor rating.
Set the motor end limits.
Verify the motor direction.
Select the correct shutter operating mode.
Check the needed parameters.
Make sure the motor is connected directly when required.
Start calibration only after all checks are complete.
Troubleshooting failed calibration
If calibration fails, check the following:
The motor is wired correctly.
The open and close directions are not reversed.
The end limits are already set on the motor.
The motor is directly connected to the shutter device.
The motor does not use extra electronics that block power detection.
Parameter No. 76 is not disabled.
The motor power is within the supported range.
The motor starts within the time set by Parameter No. 79.
The correct operating mode is selected in Parameter No. 71.
Summary
Calibration is required after shutter motor installation.
The device uses calibration to learn the motor travel time and detect the open and closed end positions.
Before calibration, always check the wiring, motor rating, motor direction, end limits, and shutter parameters.
Correct preparation helps the shutter device calibrate successfully and enables reliable percentage positioning.
