Overview

The zc-smart-blind has a Fixed Calibration mode where the product does not require an initial calibration, nor does it perform self calibration. When in this mode, the product will not adhere to the current draw of the output and will instead run for the fixed period given. This allows for the use of outputs with a current draw lower than the specification. The zc-smart-blind modes and how to configure them can be found here.

No restart of device is required for these modifications to occur.

Configuring Fixed Calibration Period

The zc-smart-blind Fixed Calibration mode has a default calibration period of 30 seconds.

zencontrol Cloud

On the zencontrol cloud this calibration is configurable via the Grid View>Device Types>Relay page. On this page, modifying the up on threshold and up off threshold will set configurations.

• Up on threshold is the time that the blind takes to go from the top to the bottom in seconds.
• Up off threshold is the time that the blind takes to go from the bottom to the top in seconds

Raw Dali commands

This value can be modified by;

eDali

To modify the calibration period over edali, you should;

1. Set ECG DTR2 to 21 (0x15)
2. Set ECG DTR0 to the desired calibration period in seconds
3. Send 0xDDxxC1
   • Where xx is the ECG address byte (as documented in IEC 62386-102)

How to Query

This value can be queried by;

eDali

To query the calibration period over edali, you should;

1. 1. Set ECG DTR2 to 20 (0x14)
   2. Send 0xDDxxC1
      • Where xx is the ECG address byte (as documented in IEC 62386-102)
   3. Set ECG DTR0 to 0 (0x0)
   4. Send 0xDDxxC2
      • Where xx is the ECG address byte (as documented in IEC 62386-102)
      • The reply will be the fixed calibration period in seconds
