1 GENERAL DESCRIPTION
MELSEC-K1, K2, and K2(S1, S2, S3). The new model has been greatly improvedin reliability
and
ease of operation, such as the increase of applicationinstructionsand the run display of all
1/0 units. The K2N is also equipped with new functions, such as a pause function which allows
a temporary stop with an output state retained.
(Features)
1.
2.
3.
4.
5.
6.
7.
8.
The conventional 1/0 units, peripheral equipment (except some units), and special units
(such
as positioningunitand analog unit)can be used without modifications.
14 types of application instructions are provided in addition to 18 types of sequence in-
structions and
8 types of data instructions.
For the operation speed
of sequence instruction, 3.8 &step or 5.6 &step can be selected.
A pause function
is availablewhich permits a stop with an output state retained.
Since all
1/0 units are provided with LED displays, running conditions can be checked.
A photocoupler insulation system has been applied to
all I/O units to improve reliability
against noise.
All external connection methods for 16-pointand 32-point
I/O units use a terminal block
connector to improveoperability.
The addition of AC input and relay output units for 32 points allows
a system to be com-
pact and extremely low-priced.
Cau
t i ons for Hand I in g
1. 3.8 ps/step or 5.6 ps/step can be selected for sequence instruction execution time.
For
a system which consists of only I/O units having type names with "N" at the
end and KI, K2 series output units, either 3.8 &step or 5.6 &step can be used.
For
a system which utilizes other units (KI, K2series input units and special units),
be sure to
set the sequence instruction operation time to 5.6 &step.
2. When the external failure number device
"F" is used, be sure to load only an input
unit intothe slot
0 of basic unit. Otherwise, the system will malfunction,
3. When
a special unit is used for a system which employs the extension base unit
K55BN or K58BN, be sure to load the special unit into the extension base unit
which requires
a basic base unit or a power supply unit.
4. For the compatibility of various type units and base units of K1 and K2series and
those of K2Nseries,
see the "APPENDIX" of this instruction manual.
5. Before proceedingto installation and operation accordingtothis instruction manual,
be sure to read Section
9 "HANDLING INSTRUCTIONS" of this manual.

3.3 Instruction on System Design
Use the control system, which utilizes the programmable controller, with special
care to the
following points:
When the power of system
is turned on or off, process output may not temporarily perform
normal operation due
to the difference between the delay time and rise time of the power
supply of programmablecontroller main unit and the external power supply (especially
DC)
for process. Also, at the time of error of external power supply or failure of programma-
ble controller main unit, output process may possibly makeerroneousoperation.
In order to prevent the aforementioned erroneous operations from resulting in the errone-
ous run of the entire system and also from
fail safe aspect, constitute circuits (such as
emergency stop circuit, protection circuit, and interlock circuit), which may result in
machine damage or accident due to erroneous operation, in the exterior of the program-
mablecontroller.
