HMI

The HMI option is a design that replaces the switches with
either a remote mount or locally mounted HMI. The HMI
option allows users to turn on/off maintenance mode over the
HMI vs. a switch.
HMI with WL Breakers
The HMI feature for the WL offers an easy way to turn on/off
maintenance mode in the WL breaker on one screen. Figure
3.3 shows an example of the WL HMI screen which has the
ability to turn on/off DAS only. The actual maintenance mode
settings are changed locally on the WL.
HMI with VL Breakers
The HMI option offers more features for the VL breaker. Figure
3.4 shows an example of the VL HMI screen. From the screen,
maintenance mode can turn on and off. In addition, the
instantaneous pickup, short time pickup and short time
pickup delay can be adjusted from this panel. The HMI option
is best used for ease of access to the maintenance mode
settings on the VL breaker. When changing the VL Breaker
maintenance mode setting over the HMI, verify the settings
are within the range of the specific VL breaker being used.
Note: Screenshots may vary between different configurations.
These are examples of what will be on the screen.
