EOC system
On the EOC system the temperature-dependent magnitude of
the magnetic field of the EOC transmitter is measured and used
for a switching pulse. The transmitter signal is transmitted via the
fixed sensor to the evaluation instrument and there compared
with the set value. If the signal does not exceed the minimum
value or no signal is received, the relay of the evaluation instru-
ment switches over. This can cause a malfunction message to
be sent and the motor cut out. The coupling housing remains
closed. The fusible safety plug with a higher response tempera-
ture remains in the coupling for additional safety.
The response temperature of the EOC system is 125 °C.
