Temperature monitoring of the motor winding with fault latch
If the supply voltage U is applied (green LED illuminated) and the cumu-
lative resistance of the PTC-circuit is less than 3.6k

Ω (standard tempera-

ture of the motor), the output relay switches into on-position. 
Pressing the test/reset key under this conditions forces the output relay 
to switch into off-position. It remains in state as long as the test/reset key 
is pressed and thus the switching function can be checked in case of 
fault. The test function is not effective by using an external reset key.
When the comulative resistance of the PTC-circuit exceeds 3.6k

Ω (at 

least one of the PTCs has reached the cut-off temperature), the output 
relay switches into off-position (red LED illuminated). 
The output relay switches into on-position again (red LED not illumina-
ted), if the cumulative resistance drops below 1.65k

Ω by cooling down of 

the PTC and either a reset key (internal or external) was pressed or the 
supply voltage was disconnected and re-applied.
