Error codes

Example of an error code
Er 1 Measuring sensor Pt100 not
inserted in A -mode of ope-
ration; LED „Temp" blinks
alternately green - red
Er 3 Internal temperature of instru-
ment exceeds 80°C LED „Temp"
blinks alternately red - orange
Er 4 speed deviation from rated to real
speed higher than ±300 1/min
LED „Mot" blinks green
Er 5 measuring sensor Pt100 not in me-
dium or wrong measuring sensor
inserted; LED „Temp" blinks red
Er 21 faulty safety relay
LED „Temp" blinks red
Er 22 firmly set safety circuit faulty;
LED „Temp" blinks red
Er 23 adjustable safety circuit faulty;
LED „Temp" blinks red
For setting back the error code
and newkalibrate the safety circuit
on a new safety temperature.
22
(see chapter „setting the safety
temperature")
Er 24 breakage of heating plate
thermocouple;
LED „Temp" blinks red
Er 25 polarity ot thermocouple;
LED „Temp" blinks red
