Mounting and start-up
Exd versions: connect the device with
anapprovedmetalcableentry(certi-
cate of conformity) or a seal box pipe.
Approvedversions(certicateofconfor-
mity) are equipped with permanently
sealed cable entries.
2. Secure grounding conductor at the
ground terminal located either inside or
outside the enclosure.
3. Check the O-ring for damage.
4. Screw on the cover as far as it will go.
Unscrewthecoveruntiltherstpossible
safety position (notch) is reached.
5. To lock the cover in position, tighten the
cap screw.
5.4 Pneumatic connection
The supply air must meet the following re-
quirements:
− Min.+0.4barabovetheuppersignal
pressure range
− Max. 10 bar
Type6116-2:max.6bar(seeECtype
examinationcerticateinsection10.2)
− Dry,freeofoilanddust(seesection3.2)
The pneumatic connections for supply air
(SUPPLY8)andoutput(OUTPUT36)arede-
signedasthreadedportswithG¼or
¼-18NPTthread.
Customaryttingsformetaltubingorplastic
hoses can be used.
Î Read the maintenance instructions for
upstream air reducing stations.
Î Blowthroughandcleanallairpipesand
hoses thoroughly before connecting
them.
Risk of property damage due to water en-
tering the device.
Î Make sure that no water can enter at the
end of an extension of the venting pipe
(minimum cross-section of 28mm² =
6mm inside diameter) connected to ei-
ther vent elbow piece or directly to the G
or NPT connection.
5.5 Mounting the i/p converter
to positioners
AnalogpositionerswithExdexplosionpro-
tection can be implemented by combining a
p/ppositionerwithaType6116-2(Exd)
Converter.
IntheType6116Converterdesignedforpo-
sitioner attachment, the connection to the po-
sitioner is used in place of the booster.
Another application involves upgrading p/p
positioners to electropneumatic positioners
(current signal input instead of the pneumatic
signal).
