Step 17: Use BESTCOMSPlus to configure the BESTlogicPlus Programmable Logic shown in Figure
70-1.
Step 18: Connect a variable resistor and set its value to 120 Ω or connect a fixed 120 Ω resistor to the
RTD1 input on the remote module in three-wire configuration as shown in Figure 70-2.

Step 19: Navigate to Metering, Motor, RTD Meter on the front-panel display and verify that RTD 1-1 is
approximately 51°C. This value may be slightly higher or lower depending on the tolerance of
the 120 Ω resistor. The value of RTD 1-1 changes according to the value of the resistor. The
RTD Bias Curve graph in BESTCOMSPlus is used to determine the starting %TC. It is
determined that the starting %TC is 13% for an RTD 1-1 value of 51°C.
Step 20: Navigate to Metering > Motor > Motor Meter on the front-panel display and verify that Thermal
Capacity is 0%.
Step 21: Apply 10 Aac three-phase current (simulate motor starting). Verify that OUT2 (Overloaded)
closes indicating an overloaded condition. Verify that OUT4 (Starting) closes. Verify that the
thermal capacity jumps from 0 to approximately 13% when current is applied and then
increases to 100%. Measure and record the time from when current is applied until OUT1
(Tripped) closes and the thermal capacity reaches 100%. The expected timing is 31.51 seconds
(87% of 36.22 seconds because %TC starts at 13%). Reference Equation 70-3. Verify that
there is a 49TC target on the front-panel display at Metering > Status > Targets.
Step 22: Remove three-phase current and wait until thermal capacity falls to 0% before proceeding.
Verify that OUT5 (Stopped) closes. Reset all targets.

Step 23: Use BESTCOMSPlus to send the operational settings in Table 70-3 to the BE1-11m. Reset all
targets.
