Operating Hours

You can enable the Operating hours counter function only for the dimmer. You enable this function for each device separately – master and extension.

If you enable the operating hours counter, the hours are counted (by seconds), and this value is stored in memory.

The actual value can be read for each relay via the 4-byte Operating hoursobject.

You set the operating hours counter as follows:

1. Go to Extended settings > Operating hours and switching cycle counter > Master/Extension operating hours > Enabled.

2. Set the expected lifetime of the device for each dimmer channel as follows:
   Go to Master/Extension output – Dimming > Dimming > Operating hours limit.

3. Set the expected lifetime of your load:
   1 – 200 000 (unit = hour).

• If the 1-bit Life time exceeded object sends 1, the lifetime of the device has been exceeded.

• The Operating hours object and the current value of the Lifetime exceeded object are transmitted after each device reset.

• The Operating hours object is sent when its value is incremented by 3600 seconds since the last transmission.

• The Operating hours object is set (but not sent) when its value is incremented by 60 seconds.

• The 1-bit Reset operating hours object is used to reset the counter of operating hours to zero. Additionally, the Lifetime exceeded object is set to zero.
