EMC-conform installation EAS
®
-Sm/Zr control unit
Attention! The described measures for compliance with the EMC-guideline for the functional-component – EAS
®
-Sm/Zr control
unit and EAS
®
-Sm/Zr clutch are examined under laboratory conditions in an approved test house and in case of deviations
cannot necessarily be transferred obligatorily to the condition of a machine or equipment. The installation instruction exclusively
refers to the use of mayr
®
-clutches. If other clutches are used the compliance of the EMC-guideline is not guaranteed.

What must be done when...?
LED mains (green) does not light
Check supply voltage.
Check fuses F1/F2.
LED fault (red) lights red
Check coil and coil connection as to short circuit or fault to ground.
LED clutch does not light
Check ON-contact as to make contact function.
LED overexcitation does not light
Limit switch contact must be open in a disengaged condition of the clutch.
Proximity switch must be damped in a disengaged condition of the clutch.
LED overload lights red
Overload at the clutch.
LED overtemperature coil lights red
Overtemperature >130 °C in the coil.
100 % duty cycle exceeded (overexcitation).
Ambient temperature too high.
Build-up of heat in the equipment.
PTC resistor is not connected or bridge is missing at the terminals P1/P2.
LED overtemperature lights red
Overtemperature >80 °C in the control unit.
Coil is not energised
Check ON-contact as to make contact function.
Check fuse F3.
Check coil as to interruption.
Clutch does not engage
Is overexcitation available?
Limit switch installation defective.
Size of the clutch and the adjusted control unit must coincide.
Engaging time t
k
too short; re-adjust it.
Residual torque of the unit too low.
Coupling speed too high.
Starting torque too high.
Max. torque
is not achieved
Size of the clutch and the adjusted control unit must coincide.
Clutch is not switched off
Check OFF contact as to break contact-function.
Clutch is not switched off in case of an overload
Check limit switch-contact as to break contact-function.
Check proximity switch as to damping.
Clutch disengages after the overexcitation
Check limit switch as to correct installation, connection and switch distance.
Engaging time too short, re-adjust it.
Adjusted torque too low.
