[2] Thermistor Trip A thermistor connected to either digital or analog input gives an
alarm and makes the frequency converter trip if upper limit of
motor temperature range is exceeded, (see par. 1-93,
Thermis-
tor Resource
.
[3] ETR Warning If calculated upper limit of motor temperature range is excee-
ded, a warning occurs.
[4] ETR Trip If calculated upper limit of motor temperature range is excee-
ded, an alarm occurs and frequency converter trips.
1-93 Thermistor Resource
Option: Function:
Select the thermistor input terminal.
[0]
*
None No thermistor is connected.
[1] Analog Input 53 Connect thermistor to analog input terminal 53.
NB!
Analog input 53 cannot be selected for other pur-
poses when selected as thermistor resource.
[6] Digital input 29 Connect thermistor to digital input terminal 29.
While this input functions as thermistor input, it will not respond
to the function chosen in par. 5-13,
Digital Input 29
. The value
of par. 5-13 remains however unchanged in parameter database
while function is inactive.
