Error Cause Corrective action
Status Byte (Status)
02h = OVERFLOW: Force sensor wrong
connected / cabling defect Correct sensor cabling
The sensor gives a signal
too big ( > ±9.92mV) Force sensor defect Replace force sensor
Status Byte (Status)
04h = ERROR A general error has appeared
while measuring – Turn machine off and back on.
– If the problem persists, check
wiring to the force sensor.
– If the wiring is ok and the
problem persists, contact FMS
customer service.
Status Byte (Status)
06h = OVERLOAD: Cabling defect (short cut) Correct sensor cabling, replace
cable if necessary
The sensor power supply Force sensor defect Replace force sensor
is overload
EMGZ470A.W: More than
1 force sensor connected There can be only 1 force sensor
connected to the EMGZ470A.W
Feedback value is > 0 even
though material is loosely Offset badly calculated Proceed for offset adjustment
again (refer to „8.6 Calibrating the
measuring amplifier“)
Feedback value doesn’t
correspond with the
effective material tension Gain badly calculated Proceed for measuring amplifier

Measuring amplifier does
not respond by
PROFIBUS (red LED
DIP switch and station
address (setting in the
PROFIBUS DP master)
don’t match Verify / correct DIP switch and

in your application
Program error; the answer
given by the measuring
amplifier is badly evaluated Correct program of the control
