Warranty
• LGIS provides an 18 months warranty from the date of production.
• For troubles within the warranty period, LGIS will replace the entire
PLC or repair the troubled parts free of charge except the following
cases;
①the troubles caused by improper treatment or operation.
②the troubles caused by external devices.
③the troubles caused by remodeling or repairing based on user’s
own discretion.
④the troubles caused by natural disaster.
• This warranty is limited to the PLC itself only. It is not valid for the
whole system which the PLC is attached.
Installation Environment
1. Please avoid installing the PLC at following locations where;
2. Please install the PLC at least 50㎜away from a duct or other devices.
3. Be sure to install the PLC in the cabinet which comply with IP54 or higher.
4. Be sure to place the PLC in the manufacturer’s original packing
while shipping or storing.
• temperature may experience ambient drops or rising.
(It should stay within 0℃to 55℃(32 ~ 131℉))
• condensation may occur due to abrupt temperature changes.
• vibration and shock are directly transmitted to the PLC.
• the PLC is exposed to the direct rays of the sun.
• the PLC is exposed to corrosive or inflammable gas.

■Characteristics
• The user program is stored in a EEPROM, and no battery back-up is required.
• Data communication through RS232C and RS485 is available.
• K10S1 includes a high speed counter being applicable for a simple positioning system.
• K10S1 series are suitable for the control of small machinery having I/O points
less than 14 .

■Power Supplying to the PLC
• To prevent the PLC from an improper
operation caused by the external noise,
place a insulation transformer and/or a
noise filter as shown in the right figure.
• Always install AC power cable and
signal or data lines in separate ducts or
bunches.

•I/O Specification
K10S1
Note)
• The expected life span of relay
The relay used in MASTER-K10S1 is FUJI’s RB1-E, and those manufacturer
guarantee 10million times (mechanical) and 0.1 ~ 3million times (electrical)
operation for their relays..
The durability of relay depends on the type of external load. Therefore, we highly
recommend customers to connect an external relay or SSR between PLC and
large inductive load for improved reliability and maintenance of PLC. The capacity
of external relay or SSR should be at least twice larger than the capacity of the
load.
• All outputs will be turned off when interruptions of CPU control, voltage drops /
interruptions, and/or power up/down occur.
• Improper terminal connection or overloads on I/O may cause a damage on the
internal devices.
