2.2.2
First steps for start up
Before the whole application can be put into operation, the following commissioning steps should be observed:
1.)
Take empty motherboard out of the box
2.)
Connect 12 V corresponding to Figure 7
3.)
Set the jumpers for driver voltages as described in Chapter 2.1.2, Table 3 and Figure 6, according to the
needs of the corresponding drivers at the daughterboard
4.)
If an adjustable powersupply has been selected, VCC2 and VEE2 has to be set by the potentiometer
according to details described in Chapter 2.1.2, Table 3 and Figure 6
5.)
Disconnect 12 V (to make all changes without power supply)
6.)
Plugging in the daughterboard and the power switches
7.)
Connect 12 V and µController interface (or other 5 V-compatible digital switching signals) to connector
X101 (see Figure 7)
8.)
Connect the high-voltage power supply (ensure that it is switched off !!) and load according to the
requirements
Now the complete setup (mothe daughterboard) is ready for testing. If all safety conditions applicable
to the respective laboratory are complied with, the high voltage can be switched on and measurements can be
started.
