Changing the parameters of protection E and S

This chapter provides you with information for changing parameters that are pro-
tected by the calibration switch and also by the code word of the ultrasonic elec-
144
tronics. This affects all parameters that are stored in the coordinates for columns E
and S. For a parameter in column S, the code word also has to be entered for the
ultrasonic electronics.
Danger
Danger to life from opening the device
If the cover or the housing of the device is opened in an area with a potentially
explosive environment, then the device is no longer suitable to be used in the
area with a potentially explosive environment. Risk of explosion!
•
Open the device only when the device is voltage free.
Mortal danger from damaged components
If threaded holes, bolts or the sealing surfaces of the housing are damaged, the
spark protection gap can no longer be guaranteed. Sparks resulting may lead to
an explosion.
•
Proceed with care when working with the bolt connections.
•
Replace damaged components with new ones.
•
Make sure that no parts of the housing are damaged.
Please note that for this task the official seal must be broken. The device
must not be used for calibrated operation if the official seal is broken.
If the task is carried out by RMG service, the device does not have to be
calibrated by a testing institute. The device is provided with a new official
seal by RMG service.
