MESSAGE
These settings allow the user to specify the length of inactivity required before returning to the restricted access level. Note
that the access level will set as restricted if control power is cycled.
• COMMAND LEVEL ACCESS TIMEOUT: This setting specifies the length of inactivity (no local or remote access)
required to return to restricted access from the command password level.
• SETTING LEVEL ACCESS TIMEOUT: This setting specifies the length of inactivity (no local or remote access)
required to return to restricted access from the command password level.

MESSAGE
MESSAGE
The dual permission security access feature provides a mechanism for customers to prevent unauthorized or unintended
upload of settings to a relay through the local or remote interfaces interface.
The following settings are available through the local (front panel) interface only.
• LOCAL SETTING AUTH: This setting is used for local (front panel or RS232 interface) setting access supervision.
Valid values for the FlexLogic operands are either "On" (default) or any physical "Contact Input ~~ On" value.
If this setting is "On", then local setting access functions as normal; that is, a local setting password is required. If this
setting is any contact input on FlexLogic operand, then the operand must be asserted (set as on) prior to providing the
local setting password to gain setting access.
If setting access is not authorized for local operation (front panel or RS232 interface) and the user attempts to obtain
setting access, then the
UNAUTHORIZED ACCESS
If this setting is "Off," firmware upgrades are blocked. If this setting is "On," firmware upgrades are allowed.
• REMOTE SETTING AUTH: This setting is used for remote (Ethernet or RS485 interfaces) setting access supervision.
If this setting is "On" (the default setting), then remote setting access functions as normal; that is, a remote password is
required). If this setting is "Off", then remote setting access is blocked even if the correct remote setting password is
provided. If this setting is any other FlexLogic operand, then the operand must be asserted (set as on) prior to provid-
ing the remote setting password to gain setting access.
If this setting is "Off," firmware upgrades are blocked. If this setting is "On," firmware upgrades are allowed.
• ACCESS AUTH TIMEOUT: This setting represents the timeout delay for local setting access. This setting is applicable
when the
LOCAL SETTING AUTH
is continuously monitored for an off-to-on transition. When this occurs, local access is permitted and the timer pro-
grammed with the
