Functions
If the supply voltage U is applied (green LED illuminated) and the
cumulative resistance of the PTC-circuit is less than 3.6kΩ (standard
temperature of the motor), the output relays switch into on-position.
Pressing the test/reset key under this conditions forces the output relays
to switch into off-position. They remain in this 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 using an external reset
key.
When the cumulative resistance of the PTC-circuit exceeds 3.6kΩ (at
least one of the PTCs has reached the cut-off temperature), the output
relays switch into off-position (red LED illuminated). The output relays
again switch into on-position (red LED not illuminated), if the cumulative
resistance drops below 1.8kΩ 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.
