outputs by means of alarm output of CH1. Therefore it is not possible
that Ch1 has 1 alarm and Ch2 has 1 alarm separately.

※2. It is able to be selected in case of only 2 channel model.

5. Explanation for function and name of parts

5.1 Function
KRN50 recorder is able to measure Thermocouple, RTD, DC-voltage

(1V,10V,50mV,200mV) DC-current(0~20mA,4~20mA) signal by total
2 input channels. Measured signal records by digital and graph type through
setting a variety of recording speed.

Alarm

: Input 1 channel can have 2 alarm outputs. Alarm output is operating by

a kinds of modes (None, Latch, Stand-by, Latch+Stand-by) through
High limit, Low limit, Sensor break, Paper end function.

Alarm outputs by relay contact.

Recording

: Measured signal records by digital and graph type. Recording speed is

able to set by 5sec~99min 59sec in case of digital mode (Numerical record)
and by 10~960mm/h in case of graph mode. It has memo function recording
data at the necessary time and is able to output time, date, alarm
information, error message, parameter list and so on.

Display

: Measured value is indicated by number on LCD display and time, alarm,

error information, etc. are displayed.

Communication Function

: It is able to use RS-485 communication and communication protocol

uses ModBus RTU and communicates with the upper devices, PC or PLC.

Data back-up

: It is similar to data logger function. In case of graph mode and 10mm/h
recording speed, approx. 10-day-data is able to be saved in EEPROM
memory. Therefore user can output the saved data from the memory by
graph or digital type.

Also even though chart paper is exhausted all, data is able to be saved
to the saving space according to recording speed.

Other function

: Feeding function and recording start/stop function are able to be used by

front key or communication at the status of recording stop. Also recording
reservation function is able to start or stop recording at the suitable time
period user wants.

1. Input must be installed as far as possible from power line.

2. Terminal wiring must be divided from high-voltage and high-current
power line in order to prevent from electricity failure and self-induction
noise. Also please avoid parallel wiring or same wiring with power line.
It may be effective if dividing by means of pipe or duct or using shield
cable or twist-pair cable.

3. Same compensating wire must be used for precise measurement when
thermocouple lead wire need to extend.
If not, it may cause an accidental error.
When RTD lead wire need to extend, please use it with small resistance

value and be equal for resistive value to 3 lead wires.

7.1 Operation mode
Recorder has 3 kinds of operation modes.

- Common operation mode

This mode operates when normal operation.
This mode operates when power on.

- Setting mode

This mode is to set the parameters as like input range, alarm, recording
speed, etc. This mode is able to set even if operation does not stop on
common operation mode.

- Backup data recording mode

This mode is to record the saved data by means of data logger function.
It is also unnecessary for operation stop.

7.2 Operation procedure
It is the introduction when this recorder operates initially.

- Ready to record

Put chart paper in paper holder after cutting the glued part (When delivery,
chart paper is installed in recorder). If necessary, change time and date
(When delivery, they are set).

- Set input and relevant parameter
Set relevant parameter according to input sensor.
ᆞSet input type and alarm

ᆞSet recording speed

- Record and display measuring value
ᆞIf necessary, press down key for recording Run / Stop.

Also mode is able to be changed by measuring value display mode
relevant key.

7.3 Setting key

- Enter into the setting mode

1. If press mode key for 3 sec, it enters into setting mode. After then the

upper setting menu refer to figure 7-2 is indicating and the cursor is
placed on relevant the upper setting menu. Scroll bar at the right side
shows the rest of the setting menu.

2. If moving from the upper setting menu to the next step menu,

please use ∨,∧ key.
