PIN
The QS841A has the ability to restrict certain access from the front panel of the unit. It incorporates a
four-digit Power Identification Number (PIN) on the front panel for certain control/operations and
configurable items. The default PIN password is 0000. Each position of the password is configurable
between 0-9. The password can be configured from the remote interfaces by a user with Administrator
privileges. The front panel PIN feature can be Enabled or Disabled through the remote interface by a
user with Administrator privileges.
Factory default for PIN operation in the standard QS840A is Disabled.
If the PIN feature is enabled, the PIN is required for items that generally are not functions of a typical
maintenance routine. It is assumed that the majority of the configured thresholds and system
operational features will not be changed through a maintenance routine. Thus, they require entrance of
the correct PIN in order for the parameter or feature to be modified in the field. There are some
Control/Operations that also require the PIN shown below.
