AccuMeter Controller Chapter 19: Security 99
Security Basics
The AccuMeter controller is setup with 3 levels of access:
1. Entry Level (no login required). This level always has access to:
• Change Recipe
• Change Target Blend Rate (for fixed rate units)
• Start/Stop feeders or blender
• View Alarms
• View Inventory
2. OPERATOR LEVEL. Login with user set to “OPERATOR” and password set to
“5413”
• All access of Entry Level
• Clear Inventory
• View and change all configuration parameters for feeders and mass flow hopper
• View Trend Info
• Access to Allen Bradley Display configuration
• Access to SETUP DIRECTORY to change units
• Access to Change OPERATOR LEVEL password
3. SUPERVISOR LEVEL. Login with user set to “SUPERVISOR” and password set to
“3145348”
• All access of Entry and OPERATOR level
• Access to ACS ENGINEERING ONLY DIRECTORY to change:
a. Enable I/O slots for PLC cards
b. Enable additional Feeders
c. Assign feeders to different blenders
• Access to Change SUPERVISOR LEVEL password
You can only modify the password for the level that you are logged in as. For example the
Supervisor cannot modify the Operator level password. This is contrary to how most security
systems work, but is the way that Allen Bradley configured their security scheme. However, if
you get locked out by an operator (or even a supervisor) who no longer has the password then
you can bypass this by the following:
1. Eject Compact Flash card from the back of the display.
2. Reboot the display with the card removed. When it comes back up you will get a
runtime error because it cannot find the card.
3. Go through the procedures in this manual to PROGRAM THE DISPLAY and the
passwords will be set back to default.
