Functions

Monitoring of motor temperature with Application of an external Reset key Application of internal Test/Reset key
fault latch
If the supply voltage U is applied (green LED
illuminated) and the cumulative resistance of
the PTC-circuit is less than 3,6 k (standard
temperature of the motor), the output relay R
switches into on-position. Pressing the Test/
Reset key under this conditions forces the
output relay R 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 3,6 k (at least
one of the PTCs has reached the cut-off
temperature), the output relay R switches
into off-position (red LED illuminated). The
output relay R switches into on-position again
(red LED not illuminated), if the cumulative
resistance drops below 1,65 k 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.

Monitoring of motor temperature with Application of an external Reset key Application of internal Test/Reset key
fault latch
If the supply voltage U is applied (green LED
illuminated) and the cumulative resistance of
the PTC-circuit is less than 3,6 k (standard
temperature of the motor), the output relay R
switches into on-position. Pressing the Test/
Reset key under this conditions forces the
output relay R 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 3,6 k (at least
one of the PTCs has reached the cut-off
temperature), the output relay R switches
into off-position (red LED illuminated). The
output relay R switches into on-position again
(red LED not illuminated), if the cumulative
resistance drops below 1,8 k 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.
