OPERATION MANUAL
「CC-Link Ver.1.10」

INTRODUCTION
INTRODUCTION
Thank you for purchasing our F156 weighing controller.
This machine based on our long-established weighing technology, is standard-loaded with
Mitsubishi Electric’s field network CC-Link interface, facilitates linking with a PLC
(Programmable Logic Controller). Also, as a fail-safe measure, it is equipped with the function
of automatically shutting off the load cell power supply when the load cell and lines are short-
circuited or overloaded.
Please carefully read this operation manual before using the F156 in order to fully deliver
excellent performance and proper and safe use.
Description in this manual
Basically, initial (default) values are underlined for selecting settings and for setting values.
Example) Digital filter
About the operational changes of the external input/output functions
In F156s with software versions earlier than 2.22, fixed functions would be assigned to external
control inputs, but these have been made selective in the same way as external control outputs;
external control input selection 0 to external control input selection 4 are added to setting codes
from 70 to 74.
For the details of respective functions, see "8.EXTERNAL INPUT/OUTPUT (Amphenol
Connector)" on p.117.
In the initial condition, the settings are as in the case of use of the simple comparison mode;
therefore, if you use the sequence mode and request the conventional assignments, please make
settings as follows:
6: 64 times
4: 16 times
8: 256 times 5: 32 times
Setting
* In this case, “4: 16 times” is the initial value.
7: 128 times
2: 4 times
0: OFF3: 8 times
1: 2 times
For use of the sequence mode (Setting code 46 “Sequence Mode” is 1)

- Connection of the ground line.
●For connection to the signal I/O terminal block, wire correctly after checking the signal
names and terminal block numbers.
Also, turn off the power of the main body before connection/wiring to the signal I/O
terminal block.
●Use shielded cable for connection with load cell unit and RS-232C.
●Take adequate shielding measures when using at the following locations.
- Near a power line.
- Where a strong electric field or magnetic field is formed.
- Where static electricity, relay noise or the like is generated.
●Do not install in the following environments.
- Places exposed to direct sunlight.
- Where the temperature and/or humidity exceeds the range in the specifications.

‘n’ (number) load cells connected in
parallel are considered one unit whose
capacity is ‘n’ x rated capacity of load
cells (load cells must have the same
capacity, bridge resistance, and mV/V).
The averaging resistor (R) must be in
same relative ratios with a low
temperature coefficient.
Averaging resistors are not needed if
load cells were designed for parallel
connection.
CAUTION
When connecting several load cells in parallel, load cell capacity should be higher than
expected load to compensate for mechanical shock or eccentric loading.

CAUTION
・The load cell excitation voltage of the F156 is 10V. Unless its maximum
excitation voltage is 10V or more, the load cell may generate heat or be
damaged.
・For connecting a 4-wire load cell to the F156, be sure to connect +EXC and
+S, and –EXC and –S. Even if +S and –S are not connected, normal
operation will seem to be performed, but the load cell may generate heat or
be damaged because excessive voltage is applied.

Connect to the cage clamp type terminal block by using the included mini-screwdriver.
1. Unsheathe the electric wire to be connected 5 – 6mm, and twist its end to such an extent that
it will not become loose.
2. Firmly insert the screwdriver into the upper hole while slightly pushing it up.
3. Insert the electric wire into the right hole so as not to loosen its end.
4. Pull out the screwdriver.
5. Lightly pull the electric wire to make sure that it is securely clamped.
