Step 25: Use BESTCOMSPlus to configure the BESTlogicPlus Programmable Logic shown in Figure
Step 26: Prepare to monitor the 49TC function operation. Operation can be verified by monitoring OUT1
(Tripped) and OUT2 (Overloaded). See Figure 267.
Step 27: Connect a three-phase current source to terminals D1 and D2 (IA), D3 and D4 (IB), and D5 and
D6 (IC).
Step 28: Connect a three-wire delta voltage source to terminals C13 (VA), C14 (VB), C15 (VC), and C16
(VN). The multiple acceleration curves allow a different curve to be created for up to three
different voltage levels for reduced voltage starting. Voltage levels between those selected for
the curves are interpolated between curves.
Step 29: Apply 10 Aac three-phase current and 108 V L-L voltage (90% of 120 V nominal). Note that
Curve 1 Voltage % is set to 90%. This means that Curve 1 is used when 90% of nominal
voltage is applied. Verify that OUT2 (Overloaded) closes indicating an overloaded condition.
Verify that the Starting LED is lit on the front panel. Measure and record the time from when
current is applied until OUT1 (Tripped) closes and the thermal capacity reaches 100%. The
expected timing is 11.52 seconds per the Overload Characteristic Curve 1 graph in
BESTCOMSPlus. The thermal capacity (0 to 100%) can be monitored at Metering > Motor >
Motor Meter on the front-panel display. Verify that there is a 49TC target on the front-panel
display at Metering > Status > Targets.
Step 30: Remove three-phase current and L-L voltage. Wait until thermal capacity falls to 0% before
proceeding. Verify that the Stopped LED lights on the front panel. Reset all targets.
