Zone 1
: The machine is deenergized for a long time. Therma image is 0%.
Zone 2
: We supply the machine with the nominal current. Thermal image evolutions so as to get the
value of the thermal balance corresponding to one time the nominal current Th = (I/It)
2
= 82%. The time
that it takes in getting the thermal balance depends on the adjusted heating constant.
Zone 3
: Once reached the thermal image corresponding to the application of one time the nominal
current, we apply 1,2 times the nominal current. Therma image will evolutione so as to get the thermal
balance corresponding to 1,2 times the nominal current Th = (I/It)
2
= 119%. This would occur if we had
the permission of the thermal function disabled. If the permission is disabled, 49 protection function
performs when the thermal image reachs the value of 100%. Once tripped, current is cutted and thermal
image is getting cool based on the cooling constant.
Zone 4
: Before getting totally cool, nominal current is applied again and thermal balnace is reached
once passed the time determined by the heating thermal constant.
Thermal image protection alarm bit is active if the thermal image measurement is over the adjusted
alarm level.
Thermal image protection trip bit is active when the measurement of the thermal image is over 100%
and it is reset when the measurement of the thermal image is under the adjusted alarm level.
4.6.2. Thermal image with memory
Thermal image is stored in non-volatile RAM memory periodically every second. By this way, though
the relay loses the power supply, it will keep the thermal status of the machine.
.
4.6.3. Thermal image measurement display. Reset.
Thermal image measuremet can be displayed on Measurement menu and Counters menu.
Display is possible in Measurement menu. Display and thermal image value reset is possible in Counters
menu.
