VPP 21 Box
Pin 3 and Pin 4: Fan Supply
When leaving the factory, there are two fans connected at this pins. This
fans are switched on by the VPP 21 box, if the temperature in the box
exceeds 50 °C. If the temperature falls under 45 °C, the fans are switched
off again.

Fig. 7-17: Characteristic data of the ready contact
If it is in the release state, the ready contact is open. It is closed after
booting the assembly. This is indicated by LED 5. The contact is opened
again, if one of the states listed below occurs:
• The 24 VDC supply falls below the permissible limit.
• One of the monitored voltages leaves the permissible range.
• The temperature exceeds the permissible limit.
• The ready watchdog runs and indicates WD_ERR.
• The reset button situated at the connector panel is activated.
