3.2 Switching outputs in “Stand-Alone residue discharge“ operation
The EPE2-Controller switching device activates the 24 Volt supply of the electronic truck computer.
The level in the metering system is monitored by the attached sensor. An additional solenoid valve
that interrupts the main air supply of the metering system is connected.
3.2.1 Switching output of the solenoid valve for the control air
•
The control air is switched off immediately after product shortage is detected.
•
The output is designed for the operation of solenoid valves with 12 volt control voltage with a
max. current of 430 mA (order no. MVS1-E11-12).
3.2.2 Power Out switching output for the flow computer
•
This output is for controlling the flow computer.
•
The deactivation of the output and hence the switching off of the supply voltage of the meter
electronics (flow computer) is time delayed (typically 8 secs ).
•
The switching output is designed for a max. switching current of 8 A at 24V supply voltage.
