6.5 Changing the Password
If a currently valid password is to be changed, a new password can be entered in the following
way:
-
Select the corresponding password field in the “Setup/System” menu.
-
You will be asked to enter the current password or to actuate the key switch.
NOTE: If you have forgotten the current password, a higher-value password can also be entered.
If the current parameterisation password is also lost, a new password can be entered by actuating
the key switch. If there is no key switch to close, connect terminal contacts 1 [GND] and 2 [PSW]
on the MST module with a wire jumper, provided that these terminals can be accessed safely.
-
After entering the password or actuating the key switch [close it briefly and then open it again],
leave the entry window by actuating the OK button.
-
You can now enter the new password in the “Password” and “Confirmation” fields of the “Set-
up/System” menu.
-
After actuating the OK button, the new password will be applied.
The password must have a minimum of four characters and may not have more than eight.
Any symbol from the ASCI character set can be used. A distinction is made between upper-
case and lower-case letters.
If no password at all is wanted, the password can be deleted here by entering nothing. Authoriza-
tion can then be granted only by the use of the key switch. In this case, an additional security di-
alog is initiated with the warning that the approval of the system is revoked in the event of
unauthorized changes.
