KV-DRIVER TEST

CAUTION
This safety measure is also valid for the chopper test
to guarantee that the measurements can be carried
out without any risks involved.
▪ Switch ON the generator.
Ignore error codes 02HI and 02HJ now, the DC supply is off and these errors must come up.
▪ Check whether the gate voltage is about -14.2 V ±0.3V against emitter for every IGBT.
▪ Check the ±15 V supply for the IGBT drivers. Drivers 1 and 2 are supplied by chopper 1 while drivers 3 and 4
are supplied by chopper 2. The common zero point is the emitter.
Emitter +15 V supply at heat sink
E1, X101
E2, X201
E3, X301
E4, X401
The kV driver test is software-controlled via PC. Due to the missing PREP and exposure requests the signals
EN_X_C/ and CTRL_X_C/ have to be set low–active at the backpanel at locations X76 and X74
(see drawing Z2-5.1/2).
CAUTION
Conv test Optimus
Before this driver test can be carried out the kV power unit(s) must be disconnected
from the mains supply (leads of unit(s) EQ/E2Q to ENK1 :1, :3, :5)
-15 V at resistor
A100 : 3 X102
A200 : 3 X202
A300 : 3 X302
A400 : 3 X402
Do not forget to remove these connections after the test. Otherwise kV start immedi‐
ately with the PREP command in normal application mode.
