5.9.2.3 UL 508-compliant I²xt motor temperature monitoring

The following test steps 1 ... 4 are part of the UL 508C-compliant device acceptance.

They have to be executed successfully during the I²xt motor monitoring.

Test step 1

• Motor overload: 6 x I

rated,mot

(I

rated,mot

: Rated motor current (C00088))

• Trigger time: Max. 20 s after the overload has occurred

Test step 2

• Motor overload: 2 x I

rated,mot

(I

rated,mot

: Rated motor current (C00088))

• Trigger time: Max. 480 s after the overload has occurred

Test step 3

• Motor overload: 1,1 x I

rated,mot

(I

rated,mot

: Rated motor current (C00088))

• In case of a motor field frequency of 10 Hz, the I²xt motor monitoring has to be tripped faster

than with a motor field frequency of 20 Hz.
