3.13.1.4 SETTING OR CHANGING A CONTROLLER PASSWORD KEY

As a security feature, the controller can be configured with a password key that is required to access
the Engineer Mode configuration function. The password key can be set by the Hand Held Config-
urer, or any of the personal computer application packages (53HC3300 or 53MT6000). It can also be
set from a SUPERVISOR-PC, but not with the controller faceplate push buttons. A password key is
a special data type (

Q1) that is displayed or configured just like any other data type using the Hand

Held Configurer. The value assigned to a password key must be an ASCII numeric string up to 10
characters because only numbers (0-9) are permitted as

KEY? input characters by the controller. To

remove a password key completely, press

CTRL 0 (hold CTRL and press zero, then ENTER.
