Thermal Curve (49TC) Test

m
capacity (0 - 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 8: Remove three-phase current and wait until thermal capacity falls to 0% before proceeding.
(Note: The thermal capacity is forced to 0% if the 49TC element is disabled and re-enabled.)
Verify that OUT5 (Stopped) closes. Reset all targets.
Step 9: Use BESTCOMS
Plus
to open the Thermal Curve (49TC) settings screen. Set the Hot Safe Stall
Time to 1,300 seconds and set the Cold Safe Stall Time to 1,500 seconds. An equivalent
current of 1.8 A is used for the steady state thermal capacity test.
The Steady State Thermal Capacity (TCU) is calculated in Equation 70-4.

Step 10: Apply 10 Aac three-phase current for five seconds (simulate motor starting). Step three-phase
current down to 1.8 Aac (simulate motor running). Navigate to Metering > Motor > Motor Meter
on the front-panel display and wait until the Thermal Capacity is 12% per Equation 70-4.
Step 11: Step the three-phase current up to 10 Aac (simulate motor starting). Verify that OUT2
(Overloaded) closes indicating an overloaded condition. Measure and record the time from
when current is raised to 10 Aac until OUT1 (Tripped) closes and the thermal capacity reaches
100%. The expected timing is 31.87 seconds (88% of 36.22 seconds because %TC starts at
12%). Reference Equation 70-3. The thermal capacity (12 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 12: Remove three-phase current and wait until thermal capacity falls to 0% before proceeding.
Verify that OUT5 (Stopped) closes. Reset all targets.
Step 13: Use BESTCOMS
Plus
to open the Thermal Curve (49TC) settings screen. Set the Max
Emergency Thermal Capacity to 200%.
Step 14: Momentarily close IN1 to enable an emergency start. An emergency start expires after one
minute if current is not applied. OUT3 toggles when Input 1 is closed. Apply 10 Aac three-phase
current (simulate motor starting). Verify that OUT2 (Overloaded) closes indicating an
overloaded condition. Verify that OUT4 (Starting) closes. Measure and record the time from
when current is applied until OUT1 (Tripped) closes and the thermal capacity reaches 200%.
The expected timing is 72.44 seconds per Equation 70-3 multiplied by 2 since the 49TC is set to
trip at 200% thermal capacity. The thermal capacity (0 to 200%) 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 15: Remove three-phase current and wait until thermal capacity falls to 0% before proceeding.
(Note: The thermal capacity is forced to 0% if the 49TC element is disabled and re-enabled.)
Verify that OUT5 (Stopped) closes. Reset all targets.
RTD Biasing (Optional)
If the RTD Biasing test will not be performed, skip to User Curve (Step 25).
Step 16: Use BESTCOMS
Plus
to send the operational settings in Table 70-2 to the BE1-11
m
. Reset all
targets.
