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.

6. Mounting and wiring
6.1 Mounting
6.1.1 Mounting location
This recorder must be mounted at the satisfied location as following condition.
- Instrument Panel
This recorder is panel mounting type.
- Airy location
This recorder must be mounted in order to prevent from overheating
(Using temp. range : 0~50℃) and follows the panel cut-out if mounting
some recorders together.
- Minimum vibrating location
This recorder must be mounted at the minimum vibrating location
where mechanism is not be influenced (Device related with print).
NOTE
●
If mounting at the location having sharply fluctuating temp. and measuring temp.
by thermocouple sensor, measured data may cause an accidental error.
Also if preheating to ambient temp. for over 30 min. before using,
measured data will be precise.
●
Chart paper may discolor if using the location having sharply fluctuating
temp. and humidity.
6.1.2 Panel mounting
This recorder must be mounted to the panel of max. 4mm thickness.
1. Insert recorder to the panel.
2.
Insert 2 fixed brackets to each bracket slots and fix them by approx. 0.3 N.m.
[Figure 6-1 Panel mounting]

6.1.3 Dimensions and panel cut-out
[Figure 6-2 Dimensions and panel cut-out]
6.2 Wiring
Warning
ᆞPlease connect wiring after power off in order to prevent from an electric shock.
ᆞ Please check input specifications in order to prevent from any damages.
FNOTE
ᆞ 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.
ᆞ If cable connected with recorder has strong power, it may cause damage to
recorder or terminal block.
!

14
- Please be care of wiring as follows in order to prevent from noise.
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.
