CHAPTER 5: SETTINGS
The following settings are available through the local (front panel) interface only.
• — This setting is used for local (front panel or RS232 interface) setting access supervision. Valid
LOCAL SETTING AUTH
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 (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 message displays on the front panel.
If this setting is "Off," firmware upgrades are blocked. If this setting is "On," firmware upgrades are allowed.
• — This setting is used for remote (Ethernet or RS485 interface) setting access supervision.
REMOTE SETTING AUTH
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
providing 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.
• — This setting represents the timeout delay for local setting access. This setting is applicable
ACCESS AUTH TIMEOUT
when the
LOCAL SETTING AUTH
is monitored continuously for an off-to-on transition. When this occurs, local access is permitted and the timer
programmed with the
ACCESS AUTH TIMEOUT
immediately denied. If access is permitted and an off-to-on transition of the FlexLogic operand is detected, the
timeout is restarted. The status of this timer updates every five seconds.
The following settings are available through the remote (EnerVista UR Setup) interface only. Select the Settings > Product
Setup > Security menu item to display the security settings window.
The Remote Settings Authorized setting is used for remote (Ethernet or RS485 interface) 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 (on) prior to providing the remote setting
password to gain setting access.
The Access Authorized Timeout setting represents the timeout delay remote setting access. It applies when the Remote
Settings Authorized setting is programmed to any operand except "On" or "Off." The state of the FlexLogic operand is
continuously monitored for an off-to-on transition. When this occurs, remote setting access is permitted, and the timer
programmed with the Access Authorized Timeout setting value is started. When this timer expires, remote setting access
is denied immediately. If access is permitted and an off-to-on transition of the FlexLogic operand is detected, the timeout
is restarted. The status of this timer updates every five seconds.

setting is programmed to any operand except "On." The state of the FlexLogic operand
setting value is started. When this timer expires, local setting access is
