The CU 6010 Central unit features the following controls and display:

￿Power switch

Switches power on to the whole system. When power is switched ON at the CU 6010 any connected EX 6010 Extension Units will automatically be powered up. An indication in the switch is lighting, when power is switched ON

￿Fault LED

This indication lights up, if the internal power supply is malfunctioning i.e. because of overheating or overload of a chain.

The Fault LED will always light up some seconds after the unit is switched on caused by the delayed switching on of the four supplies.

As a warning the light is flashing at an internal temperature above 45°C. At a temperature above 55°C or if one of the DCS-LAN outputs is supplying no voltage, the LED is lighting constantly.

Please note that the maximum ambient temperature for the CU 6010 is 40 deg. Celsius.
