FlexLogic™
Configuration
Reduced Energy Let-Thru Mode can be controlled (through FlexLogic and Discrete I/O) by a 3rd
party device.
FlexLogic and Modbus TCP can turn RELT on for individual breakers (Load protection) as well as
enable Multi-point and System Wide RELT.
Operation
Reduced Energy Let-Thru can be controlled with designated Virtual Outputs. FlexLogic can then
be programmed to control these designated Virtual Outputs through either logic or discrete
inputs.
FlexLogic will work in conjunction with other user initiated keys. FlexLogic commands cannot be
overridden. In other words, RELT will remain active as long as FlexLogic evaluates the VO high.
8.4.1 FlexLogic Programming
FlexLogic can command individual breakers into RELT. To program:
1. Find and reserve a Virtual Output: Navigate to the Virtual Outputs screen (Main Menu,
User Settings, Control) and enable and rename a spare Virtual Output for Reduced Energy
Let-Through and apply changes.
2. Configure Breaker Commands: Navigate to the Brkr Commands screen (from (User Setting,
Control) and assign the Virtual Output to one of 3 RELT commands:
• Brkr Ctrl Reduced Let-Thru Mode: Can be found in the Breaker Commands group.
There is a unique breaker command for each breaker installed in the system.
• Multipoint Reduced Energy Let-Thru Mode: Can be found in the System Commands
group. This is a system command and will initiate Multi-point RELT.
• System Wide Reduced Energy let-Thru Mode: Can be found in the System
Commands group. This is a system command and will change single-point and
multi-point RELT settings on all installed breakers.
