4-1-3. How to wire load cell connector
1) Remove a screw (1) indicated in the figure.
2) Turn and remove the lower part of the connector.
3) When looking at the connector (2) from the sol-
dering side, the pin numbers look as indicated in
the right figure.
Wire the connector appropriately in accordance
with a load cell cable you may use.
CAUTION
●
The F805AT-CK can be used only in category II specified by EN61010.
The overvoltage applied to the signal input/output terminals should not
exceed the value defined in category II.
●
The F805AT-CK conforms to the EMC Directive as an industrial environment
product (class A). If it is used in a housing environment, interference may be
caused. In that case, take appropriate measures.
●
The load cell excitation voltage of the F805AT-CK is 5V or 10V. Heating or
breakage may occur unless the load cells maximum excitation voltage is the
load cell excitation voltage of the F805AT-CK or more.
●
When using the F805AT-CK with the four-wire load cell connected, be sure to
connect +EXC and +S, and -EXC and -S. Even if +S and -S are not
connected, normal operation is performed apparently, but heating or
breakage may occur because excessive voltage is applied to the load cell.
