6 Installation and Operation of the FCU
6.1 Electrical Installation
The rear of the FCU features two sockets for connection to 24 V DC voltage supply.
The FCU can be connected to either :
•
Mains voltage via the supplied line adapters
•
24 V DC from a vehicle battery
Connect the hollow plugs of the line adapters as shown in Figure 4 : Power Supply
Sockets. The line adapters themselves have to be connected to mains voltage.
Because the shut-off valve for measurements with high pressure inlet and the pump for
measurements with suction inlet need 24 V DC supply, FCU 2110-5 / FCU 2210-5 can not
be operated independently of an external power supply.
FCU electronics and shut-off valve are supplied by the socket "Power
Input", so you don't have to use a second line adapter for high pressure
measurements.
The pump is supplied by the socket "Power Input Pump". If batteries are
charged it's possible to perform measurements with suction inlet only
with this line adapter connected.
