Ohm
Normally, the supply voltage U
B
is 24 V DC.
Taking into account the supply conductor re-
sistance directly at the terminals of the device
connector, the supply voltage may be be-
tween 12 V and 36 V DC.
Connector B
Connection of two software limit switches in
type of protection EEx ia IIC for control cir-
cuits according to NAMUR on switching am-
plifier according to EN 60947-5-6
Maximum values:
U
i
= 20 V,

i
= 60 mA, P
i
= 250 mW

i
= 5.3 nF, L
i
= 8 µH
Media 6 Z includes only one software limit
switch (Alarm 1) and one pulse output (at po-
sition "Alarm 2"), which is proportional to the
tank capacity, to control an external counter.
Test connection
(see also section 9)
Connect an ammeter to the test ter
and – to test the output signal during calibra-
tion. While doing so, the output signal of the
two-wire circuit is not interrupted. Make sure
the ammeter provides a load of < 0.4 V DC
for the test connection.
Caution!
Degree of protection IP 65 becomes ineffec-
tive when the cable socket is removed from
the device connector!
Protect the device connector against moisture
during installation and transport by keeping
the cable socket part screwed on and sealed.
