Earth connecon - Although a
terminal is provided for earth
connecon, this connecon is
oponal. The instrument does
not need earth connecon for
correct operaon nor for com-
pliance with the security regu-
laons.

Fuse - To comply with security regulaon 61010-1, add to the power
line a protecon fuse acng as disconnecon element, easily acces-
sible to the operator and idened as a protecon device.

1.10 Signal connecons
Selecng one of the sensors listed at the
‘SnSr’ menu entry, will congure the sen-
sor parameters to the values indicated in
the table.
The table also indicates the typical con-
necons for each type of sensor. Param-
eters can be manually modied.
Connecons are indicated for a single sen-
sor connected to the channel A. For two
sensors (for inhibion control, quadrature
signal, etc) apply the same connecon cri-
teria also to channel B.
Note : indicated values are typical values.
Check the correct specicaons with your
sensor datasheet and adapt the required
conguraon and connecons as needed.
