7/50D Plus or 7/50D Controller Chapter 3: Installation 51
Finishing Setup: Setting Up Passwords
You can set up passwords for two levels of security: for operators and for setup personnel.
The controller comes from the factory with neither password set. This allows every user
access to all functions.
Setup Password. If you define a password for setup personnel, then most settings can be
changed only after entering the password. The password will be required to display the
following screens:
• System Setup (to review and change system-wide settings, clear the
alarm log, and go to the network status screens)
• Station Setup (to review and change settings for all station options)
• Pump Setup (to review and change settings for all pump options)
Operator Password. If you define a password for operators, then a password will be
required to carry out any function (other than reviewing station and pump status, silencing
alarms, reviewing the alarm log, and looking at help screens). Entering the operator’s
password will give the user access to the functions at the following screens:
• Station Summary (to enable or disable a station, and start or stop
system)
• Pump Summary (to enable or disable a pump, and start or stop system)
• Station n Operator (to adjust a station’s convey time and dump delay,
activate priority convey, and review the station’s last convey time and
pump assignment; depending on the options installed, the screen may
also enable the operator to adjust the mixture percentage for a remote
proportioning valve, review the last purge time and purge valve, and
set the intended material line for material proofing)
Entering the setup password will give the user access to all functions.
Note: If you want to protect the operator’s functions with a password, you
must also define a setup password. If you leave the setup password
undefined, then all users will have access to all functions.
If you want two different levels of password protection, you must make the
passwords different from each other. If the two passwords are the same as each
other, then any user who enters the password will have access to all functions.
To set (or remove) password protections:
1. Go to the System Setup screen if needed.
To reach this screen from the Station Summary or Pump Summary screen, touch and
hold the icon for any station or pump, until the Station n Operator or Pump n Setup
screen appears. Then touch System.
