5.1 Diagnostic options on the VSPD controller card
Two output signals with the following properties are applied to the diagnostics terminal
on the front panel of the VSPD controller card (see chapter 4.1 Display/input keys and
connections of the controller card,Fig. 5 Display/input keys and connections of the
controller card*):
X1, 10 Volts for test equ

COM, ground
At diagnostics terminal "X1" you can measure the signal of analog output "AO3". The
solenoid current of the valve can be measured at this output.
In contrast to "AO3", you can select the signal to be measured. The signal is selected
in the program “BODAC“. With the factory setting, the signal “ramped command val-
ue“ is selected.
During initial startup, BODAC software can be used to select the action of the control-
ler when an error occurs (available in the “Error“ screen). If the controller card detects
an error, which has been configured with BODAC software, the error will be displayed
on the HACD controller card.
If the control card detects an error configured with BODAC software,
respond as follows:
The display will flash "ERR" (Error) on the controller card!
Press “ENTER” to display the error message and clear the error.
The procedure for selecting the action desired when an error occurs can be found in
the document “Starting up the HACD Control Card and Operation of the BODAC
Software".
