Overview

The zc-smart-blind has a Smart Calibration mode where the product will continuously calibrate to the use case to maintain accurate timing. The zc-smart-blind must undergo an initial calibration for the use case, and then will self calibrate and adjust for error. If the blind motor is unplugged from the zc-smart-blind you must recalibrate the product. The Smart Calibration mode requires the output to adhere to the output load specification found in the Datasheet. The zc-smart-blind modes and how to configure them can be found here.

Calibration

Initial Calibration

To initially calibrate the zc-smart-blind, you should;

1. Adjust the physical limit switches for the motor being used
2. Send Recall Max to the product
   • You must send this even if the blind is physically at the top. This is important so that the driver can detect its position.
3. Wait for the product to reach the first limit
   • The first limit will be arc level 254
   • This is typically the "open" position. Where this is not you should safely change the polarity of your wiring to the motor and restart calibration.
4. Send off to the product
5. Wait for the product to reach the second limit
   • The second limit will be arc level 0
   • This is typically the "closed" position. Where this is not you should safely change the polarity of your wiring to the motor and restart calibration.
6. Send Recall Max to the product
7. Wait for the product to reach the first limit again

See Behaviour when the driver is not calibrated to help identify that the driver is commissioned. To test if the blind is commissioned sending an UP or DOWN command to the blind (based on its position), should result in a valid arc level and not a value of Unknown (255).

Self Calibration

After initial calibration, the product will perform self calibration to account for error when the product detects a limit. No user intervention is required for this feature.

Behaviour when the driver is not calibrated

When the blind is not calibrated you cannot control an absolute level on the blind. To control the absolute level see Calibration above.

• The control gear will show lamp failure
• DALI Arc Level:
  • The arc level will be 254 when it is at the opened limit.
  • The arc level will be 0 when it is at the closed limit.
  • The arc level will be 255 when the blind is at any other point.
• DALI command UP: This will cause the blind to travel up a small amount. 
• DALI command DOWN: This will cause the blind to travel down a small amount.
• DALI command DAPC: DAPC will make the blind travel a small amount in a direction based on whether the level is above or bellow value 128.
  • IE,
    • DAPC 20 will travel down a small amount.
    • DAPC 200 will travel up a small amount.
  • Where the value is 254 the blind will travel up until it hits a limit.
  • Where the value is 0 the blind will travel down until it hits a limit.
• DALI command RECALL_MAX: The blind will travel up until it hits a limit.
• DALI command OFF: The blind will travel down until it hits a limit.
