Watson-Marlow 720DuN User Manual 57
Repeat the digit-entry sequence.
If the second three-digit code entered differs from the first, or if the digits cho-
sen as a user code are the same as those already set as a main code, the
pump briefly displays an error message and redisplays the set code options
screen.
If the codes tally and, for a user code, if there is no clash with a previously set
main code, the pump briefly displays a confirmation message and redisplays
the sixth Setup screen. Access to the Setup and Configuration menus, direction
control and keypad lock is now protected by the new security code.
If STOP is pressed during code entry, the pump returns the user to the sixth
Setup screen. If STOP is pressed during code confirmation, the pump returns
the user to the first digit-entry screen.
Note: A user code cannot be set unless a main code has previously been set. If you
wish to cancel only a user code, you must use Cancel codes to cancel both user
and main codes, then use Set main code to set a new main code.
Note: If a code has been set but forgotten, it is still possible to access the Setup
screens to cancel the code or reset it to another three-digit number. Contact your
supplier or Watson-Marlow Technical support for the bypass sequence.
