Operating Manual EMGZ421
28
11 Trouble shooting
Error Cause Corrective action
„Err1“ is displayed:
A/D-converter receives Force sensor A is wrong
connected Exchange wires on terminals z6 / z8 (resp. 2 /
3)
values < -9.7mV
continuously
Parting of the cable Replace connection cable between force
sensor A and measuring amplifier
„Err2“ is displayed:
A/D-converter receives Force sensor A is wrong
connected Exchange excitation and signal (terminals z4
... z10 resp. 1 ... 4)
values > 9.7mV
continuously Short circuit in the plug
or connection cable Check and correct wiring to sensor A
Force sensor overload Use sensor with higher nominal force
Force sensor has too
much sensitivity Set parameter sensitivity sensor A to the
correct value or use other sensor
„Err3“ is displayed:
A/D-converter receives Force sensor B is wrong
connected Exchange wires on terminals d6 / d8 (resp. 7 /
8)
values < -9.7mV
continuously Parting of the cable Replace connection cable between force
sensor B and measuring amplifier
„Err4“ is displayed:
A/D-converter receives Force sensor B is wrong
connected Exchange excitation and signal (terminals d4
... d10 resp. 6...9)
values > 9.7mV
continuously Short circuit in the plug
or connection cable Check and correct wiring to sensor B
Force sensor overload Use sensor with higher nominal force
Force sensor has too
much sensitivity Set parameter sensitivity sensor B to the
correct value or use other sensor
„Err5“ is displayed:
Output 1 (A–B) shows
minimum continuoulsy Offset badly adjusted Proceed for offset adjustment again
„Err6“ is displayed:
Output scaling badly
adjusted Set parameter Scale output 1 to appropriate
value
Output 1 (A–B) shows Offset badly adjusted Proceed for offset adjustment again
maximum continuoulsy Gain badly adjusted Proceed for sensor calibration again
Feedback value is > 0 even
though material is loosely Offset badly adjusted Proceed for offset adjustment again
Feedback value isn’t stable
even though Cut-off frequency of the
filters set too high Adjust cut-off frequency (ref. to „8.3
Additional settings“)
material tension doesn’t
change Ground terminal ogf the
output isn’t 0V Connect Gnd terminal of the output (terminal
z22 resp. 14) with earth (terminal z24 resp.
PE)
Feedback value doesn’t
correspond with the
effective material tension Gain badly adjusted Proceed for sensor calibration again
No message on the display Display contrast setting
is bad Set display potentiometer correctly. (It is
located on the processor board on the upper
right edge beside the ribbon connector)
Fuse blown Replace fuse on power supply
Power supply not
correct Check / correct power supply
