7 Troubleshooting
7.1 Product remains inoperable even after the power supply is
turned on
Possible cause Corrective action
Cable connected incorrectly. Check connection. Check control cabinet.
Fuses trip. Check fuses and cables of the product.
Fault circuit interrupter trips. Check magnetic gripper connection to ground
connection.
Mains voltage or frequency differ
from ECG setting.
Contact the SCHUNK contact person.
Magnetic gripper and ECG are not
compatible.
Check compatibility for max. permitted number of
magnetic grippers and max. permitted cable
length(20m) to the magnetic gripper (see catalog
datasheet EGM).
7.2 Workpiece disengages from the magnetic gripper.
Possible cause Corrective action
Product is not performing the
magnetization or demagnetization
process at all or not correctly.
Check the product, cables and connections for
damage.
Check the activation times and correct if necessary.
Before magnetization, the magnetic surface must lie
completely against the workpiece.
Check the type (ramp) and duration of commands
and correct if necessary, Chronological sequence of
the control and status signals [

32]
The holding force is not sufficient. Pay attention to instructions on workpiece suitability
and holding force in the documentation of the
magnetic gripper.
Only ECG-R: Select a higher holding force level and
repeat the magnetization process, Adjusting the
holding force [
}
32].
7.3 Demagnetization was not performed correctly.
Possible cause Corrective action
External grid disturbances impair
product functionality.
Install a power line filter upstream of the product.
Lack of actuation or incorrect
command sequence.
Check required signals.
