Application
Switching, controlling, monitoring and overload signalling of
adjustable EAS
®
-Sm synchronous-clutches, EAS
®
-Zr overload
clutches.
Function
The EAS
®
-Sm/Zr-control unit works according to the cycled
switching controller principle with a frequency of 18 kHz.
It switches, controls and monitors the clutch and signals when the
set torque is exceeded.
