Using the Simulator Tool
The Simulator tool allows you to simulate values regardless of the actual inputs that the
sensors register. The 509ITM responds to the input signal changes from the
Simulator
window as if the signals originated in the field. This mode is useful for testing items such as
relay connections and wiring.
When you click [Start Simulation]:
The field inputs disconnect from the actual field signals and connect to the signals from the
Simulator tool. You can now change the simulated signals remotely as you desire. The
509ITM responds to the simulated signals as if they were the actual field signals.
With the exception of the “CT, Temperature” signals, the transfer from the field to the
simulation is almost undetectable because the initial simulation value is set to the last value
of the actual field signal.
The winding temperature (“CT, Temperature”) is a calculated value
using load currents, oil temperatures, and time constants. All of these are bypassed in the
simulation mode where the calculated values are replaced with the simulated values.
Important:
While the simulation is active, the actual field signals are not being monitored.
If you have Trip functions connected to the 509ITM, you can activate them in
simulation mode.
