16 PIN-secure process protection
The 520DuN and 520Du feature PIN-secure process protection. This allows the
pump to be configured to suit the application, and for the setup to be protected
by two levels of PIN code. See 18.19 Security code setup.
* When the keypad is locked, MemoDose is available via its access shortcut:
press STOP twice; it is not available through the menu structure.
The main code allows changes to Calibrate, Setup, Direction and Keypad
lock.
The secondary (User) code permits Calibrate, Direction change and Keypad
lock but bars Setup change.
If either code is used in conjunction with Keypad lock, all keys are disabled
except STOP and START.
To activate and set a security code, see 18.19 Security code setup.
If the main code is lost or forgotten: The Setup main security code can be
bypassed by entering a special key sequence; all codes can then be cancelled
and reset. Contact Watson-Marlow or your distributor for details.
