Starting, Operation - WIKA E-10 Betriebsanleitung

5. Packaging / 6. Starting, operation
In order to protect the diaphragm, the pressure connection of the instrument E-11 is provided
with a special plastic protection cap.
Remove this plastic protection cap only just before installing the pressure trans-
■
mitter in order to prevent any damage to the diaphragm or the thread.
Keep the plastic protection cap of the pressure connection thread and the
■
diaphragm for later storage or transport.
Mount the plastic protection cap when removing and transporting the instru-
■
ment.

6. Starting, operation

6.1 Diaphragm test for your safety
Required tools: wrench (flats 27), screw driver
It is necessary that before starting the pressure transmitter you test the diaphragm, as this is a
safety-relevant component.
WARNING
Pay attention to any liquid leaking out, for this points to a diaphragm damage.
■
Check the diaphragm visually for any damage (E-11).
■
Use the pressure transmitter only if the diaphragm is undamaged.
■
Use the pressure transmitter only if it is in a faultless condition as far as the
■
safety-relevant features are concerned (e.g. no damage of case, cable and
connection threads. Otherwise explosion protection is not ensured).
