PIN code
The access code (PIN code) is designed to prevent unauthorised persons from
changing programming parameters. The code is requested on start-up.
Parameter settings can be viewed but not changed if the entered code is incorrect.
This applies in both the on-line and off-line operating modes.
Revoking access
The
Delete access
button reactivates PIN code protection of the parameter
settings. You must then enter the PIN code again if you want to change parameter
settings.
The PIN code itself is set in a different program. For security reasons, an external
program, vm_pin.exe, is used to set the PIN code.
The following PIN code is active when the program is supplied initially:
12345
If you have used the external program vm_pin.exe to set the PIN code, you must
delete this file from the hard disk afterwards to prevent unauthorised persons from
changing the PIN code.
If there is no need to safeguard against unauthorised use, the PIN code request
procedure can be deactivated by entering the following preset deactivation code:
54321
If this option is in use, there is no requirement to enter a PIN code, however the
PIN code window will briefly appear and then close automatically when the
program starts up.
