•
The terminal area of the devices is part of the service. Here electrostatic discharge
needs to be avoided. Attention! High voltages can cause dangerous body currents.
Galvanic insulated potentials within one complex need to be placed on an
appropriate point (normally earth or machines ground). So, a lower disturbance
sensibility against impacted energy can be reached and dangerous potentials,
that can occur on long lines or due to faulty wiring, can be avoided.
15. Error elimination
Error description
Measures
1. The unit permanently indicates
overflow.
• The input has a very high measurement,
check the measuring circuit.
• The input is open.
2. The unit permanently shows
underflow.
• The input has a very low measurement, check
the measuring circuit.
• The input is open.
3.
• The unit has found an error in the
configuration memory. Perform a reset on the
default values and re-configure the unit
according to your application.
4. Program numbers for parameterising
of the input are not accessible.
• Programming lock is activated
• Enter correct code
5.
• Please contact the manufacturer if errors of
this kind occur.
6. The device does not react as
expected.
• If you are not sure if the device has been
parameterised before, then follow the steps as
written in
chapter 10
and set it back to its
delivery status.
7. The temperature value is unstable.
• Please check the possibility to set aside the
galvanic insulation for a discharging of failures
as described under
chapter 7
„Electrical
connection“. Before make sure that the
possible metal sensor is separated from the
sensor element.
