I-11 Maintenance, test, trouble shooting
I-11.1 Cleaning
Housing and front panel can be cleaned using a dry, lint-free cloth. No use of solvents or cleansing agents!
+ Avoid using solvents or cleansing agents!
I-11.2 Behaviour in case of trouble
The unit needs no maintenance. In case of trouble, check:
w Is the unit in on-line mode ?
w Is the supply voltage connected correctly? Are voltage and frequency within the tolerances?
w Were all connections made correctly ?
w Do the sensors and actuators work properly?
w Is the engineering OK?
w Is the unit configured for the required operating principle?
w Do the adjusted parameters have the required effect?
w Are the I/O extension modules plugged in and clicked in position correctly (modular option C)?
w Is a terminating resistor activated (can be required dependent on the instrument position in the bus topology with
CANopen and PROFIBUS DP)?
w Were the required EMC measures carried out (screened cables, earthings, protective circuits, etc.)?
w Does the diagnostic page of the test engineering indicate an error?
If the unit does not function correctly after these checks, it must be shut down and replaced. A defective unit can be
returned to the supplier for repair.
I-11.3 Shut-down
a
Disconnect the supply voltage completely and protect the unit against accidental operation. As the instru -
ment is mostly connected with other facilities in the control loop, consider the effects before switching
off and take measures to prevent the occurrence of undesired operating conditions!
I-11.4 Test engineering as basic equipment
KS98-1 is factory set for a test engineering IO-test.edg, which ensures checking of the possible inputs and outputs of
the extended basic unit (standard + option B + option C). If KS98-1 is provided with a customer-specific engineering,
the relevant description is applicable.

If KS98-1 is provided with customer-specific engineering, the engineering description is applicable.
A diagnostic page is provided to indicate system errors in case of start-up problems. The availability of the real-time
clock is also displayed. The display colour can be changed green/red and normal/inverse.
