number of terminal. (It may cause a fire)
4. Turn off the power during wiring and maintenance to avoid an electric shock.
5. Do not touch the terminals when it is power on.
(It may give an electric shock.)
6. This controller must be mounted on the panel to avoid an electric shock.
7. Do not attempt to disassemble, modify and repair.
1. Please conduct an inspection when water has entered the product.
(It may cause short circuits, fires, and malfunction.)
2. This controller should be used indoors.
(It may shorten the controller’s life or give an electric shock.)
3. Observe the rated voltage and specification.
(It may cause a fire or shorten the controller’s life.)
4. Be careful that any of foreign materials do not inflow into the controller.
(It may cause a fire or malfunction of the controller.)
5. Do not give direct vibration or shock to the controller.
(It may cause of malfunction of the controller.)
6. Do not use chemical detergent or solvent, but use a dry towel in cleaning the controller.
(It may cause an electric shock or a fire.)
7. Please check the polarity of power before wiring and connecting the sensor.
(It may cause an electric shock or explosion.)

How to change the interior switch when using 1~5V input
①Remove the jumper cover
on the underside of the T50,
or remove the rear case.
②Detach the jumper using
tweezers and move it to
the 1-2 pins to the left.
③Once this has been com-
pleted, put the jumper
cover back on, as shown
on the picture above.
※When using 1~5V input (30),
the interior jumper switch must be
relocated.
OTHER TYPES 1~5V DC INPUT ONLY

2-2. Output constitutions
K50 SERIES can use up to three different alarm outputs for 21 different types.
ln addition, the unique output confguration of the system allows the user to designate the output port freely, and the alarm 1~3 outputs
can be exchanged or used together.

7. Check Points before Using
1) Default values at the point of manufacture
2) 7 Segment display indications
3) Initial display on power supply (K54-SERIES basis)
The default input and output values of the product at the point of manufacture are as follows.
Input : K-Type (Sel. code 1) Output : SSR mode (Sel. code 1)
※In the case of the basic model of K34-S00 only, when SSR(1) or SCR(2) is chosen as the
output mode, Alarm 1 output will be in main relay. (Refer to page 8 for details)

8. Initial installation and minimum operation procedures
The following are the instructions for initial installation and minimum operation procedures.
Please read the contents of this manual, including the general functions outlined here, as thoroughly as possible before operating the device.
To ensure safety and prevent wrong operation, once auto-tuning has been completed, "level-2"
(setting menu display limit) will be set automatically.
At the same time, setting menu output group(8.out) and input group(9.in) are not displayed.
If needed reset, please change to "level-3"(setting menu display limit)and operate.
Please refer to the "3) setting menu display limit" at page 22.
1）Check the external wiring diagram and specifications
(power supply and terminal arrangement)
2）Check input and output specifications!
The default setting for the K50 series at the point of manufacturer are as follows.
Input : K(CA) Type (setting code 1)
Output : SSR mode (setting code 1)
If you wish to change the input or the output type, please select the option
you desire on the input group and the output group menus.
※The input type settings must be configured first before changes to other set values are made.
When the input type is changed, all other parameters (set values) are reverted to their
factory default.
3）Select the desired set value (SV).
4）Please set auto-tuning or P, I, D values to suit the operating environment.
Auto-tuning is recommended except under special circumstances
