5 Start-up
Before voltage is applied to the equipment the following checks must be performed:
Check that screws are firmly seated in
Connecting terminals, protective earth conductor terminals and
potential equalisation terminals
Housing cover
Check
The torque of the cable lead-in
The tightness of the seal provided by the cable lead-in
Check whether the equipment is ready for operation
The parameterisation for this application must have been performed
All interfaces such as inputs and outputs for control purposes must be connected
and ready for operation
5.1 Parameterisation
Equipment parameterisation
Define all application-specific parameters.
Once the power supply is applied, the equipment is ready for operation immediately.
6 Maintenance / service
The equipment can only be guaranteed to operate safely and reliably
in the long term if regular inspections and servicing are carried out. These include the following:
For cleaning the devices it is necessary to take care that no electrostatic charging will be done (no
high volume flow, cleaning only with damp cloth,…)
An inspection includes
Visual inspection
o
Mechanical damage
o
Non-permitted dust deposits
o
Other irregularities or error messages from the equipment
Checking of components (wearing parts) whose functionality or purpose changes and af-
fects the operation of the equipment
Documentation of what was done by whom, and when
Maintenance includes
Functionality checking
o
Operating statuses such as alarms etc.
Checking calibration values (= calibration)
o
Triggering of alarms by known process parameters (test pressure etc.)
Correction of calibration values (= calibration) must be carried out in the factory
Documentation of what was done by whom, and when
6.1 Time intervals
Inspection:
The condition of the equipment must be checked at regular intervals. The time interval is extreme-
ly dependent on the local situation and the degree of use, and must therefore be adapted to re-
quirements. Extremely short time intervals can be specified such as once per day, every new shift
etc.
Defined by the operator in accordance with local requirements
