Functions
If the supply voltage U is applied (green LED illuminated) and the
cumulative resistance of the PTC-circuit is less than 3.6k
cumulative resistance of the PTC-circuit is less than 3.6k
Ω (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 3.6k

Ω
(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 1.8k
