Description
Displays the enabled Motor Winding Temperatures for phase A, B and C. The setting
of the Winding Temperature Protection Setpoint affects this display as follows: When
winding RTDs are enabled, there are two temperatures for each phase displayed
(otherwise, there is only one for each phase). When set to Disabled, no temperatures
are displayed and the heading, text and data boxes do not appear. Individual
temperatures can be disabled using the Temperature Disable Setpoint on the Motor
Setpoints Screen. When an individual temperature is disabled, the temperature data
box does not appear. Any RTD input that registers as an open RTD is considered
invalid and displays as XXX.X.
This value is calculated as the average of all enabled and valid Motor Winding
Temperatures. Any winding temperature that registers as open, out of range or
disabled is not used in the calculation. When RTDs are used for winding temperature
measurement, there are a maximum of 6 temperatures used to calculate the average.
When transmitters are used, there are a maximum of three temperatures used to
calculate the average. The text description and data box do not appear when Winding
Temperature Protection Setpoint is disabled.
Illuminates when the enabled Motor Cooling Coil Leak Detector (see
Coil Leak Protection) indicates a leak. The LED and text description do not appear
when the Motor Cooling Coil Leak Protection Setpoint is set to Disabled.
