REV. 1.40
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)
Setting code Setting value Pin No. FUNCTION
70 8 10 No function
71 5 11 Feed/Discharge
72 2 12 Tare subtraction
73 6 13 Sequence start
74 7 14 Sequence stop

follow divide into and , and are indicated by the following
documents. Notes indicated here are the serious contents related safely. Please use after
understanding the contents well.
WARNING CAUTION
WARNING
Misuse may cause the risk of death or serious
injury to persons.
CAUTION
Misuse may cause the risk of injury to persons
or damage to property.

Safety Precautions
WARNING
●Use F156 with correct supply voltage.
●Carefully check wiring, etc. before applying power.
●Do not disassemble the main body for modifications or repair.
●Be sure to use crimp contacts for connection to terminal blocks, and do not to connect
bare wires as they are.
●Be sure to ground the protective ground terminal.
●When smoke, a nasty smell, or strange sound, please shut off a power supply
immediately and extract a power supply cable.
●Do not install in the following environments.
- Placeｓcontaining corrosive gas or flammable gas.
- Where the product may be splashed with water, oil or chemicals.
●About the built-in lithium battery
Never disassemble, deform under pressure or throw the battery
into fire.The battery may explode, catch fire or leak.
- Battery
Model : CR14250SE made by SANYO Electric Co., Ltd.
Nominal voltage : 3V
Nominal electric capacity : 850mAh

Safety Precautions
CAUTION
●Be sure to disconnect the power cable when performing the following.
- Attachment/detachment of load cell connector, external I/O connector, console or
RS-232C connection connector.
- Wiring/connection of cables to terminal blocks.
- 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.
- Placeｓwith large quantities of dust, salt or iron powder.
- Where the main body is directly affected by vibration or shock.
●Do not use it, broken down.
●When you send F156 by repair etc., please take sufficient measures against a shock.
