Figure 55 - View Instantanious Meter Values Once - Example
METER T (Thermal and RTD Metering)
The METER T command displays the temperatures of any connected RTDs.
This command also shows the average motor current (x
I
e
), the present
% Thermal Capacity used, and the RTD % Thermal Capacity (if ambient and
winding temperatures are monitored and a winding RTD trip temperature is set).
If the motor is in overload, this command response shows the calculated time to a
thermal trip. If the motor is not in overload (e.g., see Figure 56), the time shown is
9999 seconds. The Starts Available and Time To Reset values are also displayed.
