7.3. Power Supply system check
When something goes wrong it’s useful to check the status of all the above mentioned supplies.
The main board has the capability to measure all internal supplies. The only requirement is that the +5V
Digital supply is available. This is indicated by the red led on the rear panel of the programmer.
All the other supply could be checked by the Measurement system itself. Channels 8 till 11 are reserved
for this. The channel 8 is connected to the driver supply and is very useful to check the voltages of the
connected external supply. This can be useful to check when applications are launched where extra high
voltage is needed. Refer to the chapter “Measurement system” for more details about measuring these
channels. There are DLL functions available that will do these checks for you.
A typical diagnostic check will start with checking if the external supply is available. Then it will check if the
red led is lit. If these steps are ok, the diagnostics via software can be executed.
7.4. Supply Connector
This connector provides the PTC with power.
Any power source that generates a voltage between 24 and 48 V DC with a minimum current of 1.5 A is
allowed.

7.8. Reset button
This button is connected to all reset lines in the main board as well as on the daughterboard. This button
allows the user to reset the whole programmer after crashing software and when connected also to the
application device under test.
