5Installation
5.1 Installation places
Install this unit in place where the below conditions are satisfied.
Instrument Panel
This recorder is panel mounting type.
Place where ventilation is well
To prevent from malfunction and damage by overheating (use temperature range: 0 to 50℃),
install this unit where ventilation is well.
In case installing several KRN50, space each other by panel cut-out.
Place where vibration is not severe
If there is too much vibration, it may cause malfunction such as print error.
In case of temperature measurement with thermocouple temperature sensor at the place
where temperature is fluctuated, data error may occur. You should warm-up this unit over 30
min. to acquire accurate data before using it.
At the place where temperature and humidity is fluctuated excessively, recording paper
color may be changed.

5.2 Installation
5.2.1 Panel mounting
Install KRN50 on the processed panel as panel cut-out diagram. Mount fixing brackets
on upper/lower parts.
Tighten fixing brackets on upper/lower parts to fix on the panel with phillips screwdriver
(+). (Torque: 0.3N•m)
Wire cables to the rear terminal block.
If using only 1 channel in case of 2 channel model, please short-circuit the input channel (+,-
input) not used in order to prevent from noise influence.
If cable connected with recorder has strong power, it may cause damage to recorder or terminal
block.
Input must be installed as far as possible from power line.
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 twisted-pair
cable.
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.
Connect wiring after power off in order to prevent from an electric shock.
Check input specifications in order to prevent from any damages.

6 Functions
20 © Copyright Reserved Autonics Co., Ltd.
6Functions
KRN50 recorder is able to measure Thermocouple, RTD, voltage (1V DC,10V DC,50mV
DC,200mV DC), current(DC 0 to 20mA, DC 4 to 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
to 99min 59sec in case of digital mode (Numerical record) and by 10 to 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 backup function (Record 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 functions
Feeding function and recording run/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.

7General operation and parameter setting menu
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 (Record 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 (chart paper is installed in
recorder as factory default). If necessary, change time and date (they are set as factory
default).
Set input and relevant parameter
Set relevant parameter (input type, alarm, record speed) according to input sensor.
Record and display measuring value
If necessary, press key for recording Run / Stop. Also mode is able to be changed by
measuring value display mode relevant key.
