Energy (or Max/Min, Demand, Peak Demand) metering data can be reset
from the front-panel HMI by selecting the
Reset menu item in the Energy (or
Max/Min, Demand, Peak Demand) menu. After selecting Reset and confirming
the reset, the relay displays as shown in Figure 8.8.

Demand) Metering Is Reset
Assume the relay configuration contains no analog input cards. In response to
a request for analog data (selecting
Analog Inputs), the device displays the
message as shown in Figure 8.9.
Figure 8.9 Relay Response When No Analog Cards Are Installed
Assume the math variables are not enabled. In response to a request for math
variable data (selecting
Math Variables), the device displays the message as
shown in Figure 8.10.
