All information contained in this manual, unless indicated, is valid for both JR-E and JR20-E models.
JR-E and JR20-E models from KOSMOS serie are universal digital indicators fully configurables that allow input
type selection in order to be used as needed. Available signal inputs are the following:
DC VOLTAGE (±600V, ±200V and ±20V)
DC CURRENT (±5A, ±1A, ±100mV and ±60mV)
AC VOLTAGE (0-600V, 0-200V and 0-20V)
AC CURRENT (0-5A, 0-1A, 0-100mV and 0-60mV)
The basic instrument consists of a soldered assembly composed of a main board, a display and an input signal
circuits. It can also be incorporated, as an option, an extra plug-in 2 SPDT 8A relays circuit output which is isolated
from signal input and power supply. This extra circuit has independent connectors that are located on the rear part
of the instrument once it is installed.
Specially designed for the industrial signals monitoring, both models have 4 digits, configurable decimal point and
2 LED’s for setpoints status indication, they are easy to scale into desired engineering units, directly by frontal keys
or rear input signal value in teach mode.
JR-E model is provided with 14mm-high digits and maximum display range of -9999 to 9999 whereas JR20-E
has 20mm-high digits and a maximum range of -1999 to 9999. JR20-E has a larger display to provide a better
reading at longer distance, although minus LED sign is integrated in the most significative digit instead of being
external, as in JR-E model.
Both devices have three frontal keys to interact with internal software and set configuration in order to adapt their
function to particular applications. Device programming runs through some independent menus that show short
messages to easily identify input type and/or display configuration steps.
If relays output option card is installed, once it is recognised by the instrument, activates its own configuration
menu which is only visible under this conditions.

Input signal connecting guidelines.
WARNING:
 Where possible, connect neutral of the signal input (including current shunts) to the input common
of the indicator. If the input signal is sourced from an active circuit, connect the lower impedance
(usually circuit common) to the input signal common of the indicator.
 For phase-to-phase line monitoring where a neutral does not exist, or for any other signal input in
which the isolation voltage is exceeded, an isolating potential transformer must be used to isolate
the input voltage from earth. Input common of the indicator then must be earth referenced for
safety.
 It is recommended to use a current transformer for currents line measuring. If an external current
shunt is used, it must be inserted in the neutral return line. If isolation voltage is exceeded, then an
isolating current transformer must be used.

INPUT CONFIGURATION
When connecting instrument to Power supply, display test begins automatically to check the good function of LEDs
and digits, once this test is finished, display shows internal software version and then the unit goes to RUN mode.
Configuration software has a hierarchical structure composed of a number of menus and submenus. By pressing
ENTER key, display shows “Pro”, a new pressing brings access to main menu where appear configuration menus,
that is, input configuration (InP), display configuration (dSP) and setpoints configuration (SEtP). This last menu
only appears if 2RE output option card is installed.
If configuration is totally locked-out, when pressing ENTER key to get into main menu, display shows “dAtA”
instead of “Pro”. This indicates that it is only possible to see programmed information and that it is not allowed to
modifiy any parameter from the entire configuration. In this visualization mode, the instrument automatically
switches back to RUN mode after 15 seconds since last key press.
Configuration menu
The instrument provides 3 keys for progressing through the
menus and submenus and for data introducing/modifying:
ENTER:Vertical displacement / Validates data.
UP:Increases active digit value.
SHIFT:Horizontal displacement / Changes active digit.
Input configuration
The first menu corresponds to input configuration. This, in turn, consists of four submenus, one for each input
type: DC voltage (UDC), AC voltage (UAC), DC current (AdC) and AC current (AAC).
Once inside each menu, all configuration parameters are sequentially shown and they can then be introduced or
edited by pressing ENTER key. Numeric values must be entered digit by digit, first selecting digit and then
changing its value. When the display reach desired value, a new ENTER key pressing validates data and routine
goes forward to next configuration step.
Data entered or changes made during configuration are stored in device memory only when programmation
routine belonging to the respective submenu is completed, not before. On last routine step and after having
pressed ENTER key, display indicates “StorE” and the unit goes back again to RUN mode.

DISPLAY CONFIGURATION
Display Programming
Display scaling
IMPORTANT IN “tEAC” MODE:
To ensure the best accuracy, both points 1 and 2
should represent extreme process limits.
The second menu corresponds to display configuration. This, in turn, consists of some submenus: through frontal
keys configuration (uSEr SCAL), through real input signal (TEACH) (uSEr “tEAC”), calibrated range (CAL)
and reading stabilization filter (FiLt).
TRHOUGH FRONTAL KEYS CONFIGURATION “SCAL”
Input and display values are configured manually through
the three keys of the instrument. This method is suitable
when signal values supplied by the transducer at each
extreme point of the process are known.
REAL INPUT SIGNAL CONFIGURATION “tEAC”
Input values are directly introduced from CN2 input
connector just at the moment of signal capturing at
each point of the process. Display values are configured
manually through the three keys, as in the previous case.
This method is suitable when signal values at each point are
unknown but, it is possible to lead process to the conditions
defined by these extreme points.
WEIGHTED AVERAGE FILTER “FiLt”
Sets low-pass filter cutoff frequency (Fc) which allows the instrument to smooth out undesirable display reading
fluctuations.
Display scaling is necessary when adapting display reading to a particular engineering unit. Display range can be
configured between -9999 and 9999 for JR-E (14mm-high digits) or between -1999 and 9999 for JR20-E
(20mm-high digits).
Display scaling is a linear process that consists in introducing two input values, referred as Input 1 and Input 2,
and their respective display values, referred as Display 1 and Display 2. On the basis of this proportional
relationship internal software calculates display value that would correspond to a given input value. Decimal point
position would complete required engineering units indication.
It is possible to scale display in an increasing or decreasing proportional mode depending on whether if second
display value (DISP.2) is greater or less than the first (DISP.1). In an increasing mode, display value increases
proportionally to the input value whereas in a decreasing mode, display value decreases. The left figure below
shows both scaling modes.
The right figure shows a
display scaling example for a
5A current measure using a
60mV shunt. Decimal point is
situated between second and
third digit of the display.

Thanks to this feature there will be no need to reconfigure relays setting when 2RE output option is again installed
if the same configuration is required.
The third menu “SEtP” only appears when two relays output card is
installed. For further details on function modes please refer to the
corresponding OUTPUT OPTION part later on this manual.
Programming steps are equal for both relays on each “SEt1” and
“SEt2” submenus. The parameters to be configured are the following:

In addition to already known functions used to browse through the configuration menus and submenus, introduce
and/or modify existing values and parameters, the instrument provides some more added functions.
This device detects and stores in memory maximum and minimum values reached by the input signal. This values
are kept in memory although power supply is desconnected. When pressing repeatedly SHIFT key, MAX/MIN
function shows saved maximum and minimum values in display since last RESET function activation.
In order to differentiate this values indication from a mode RUN indication, decimal point blinks during the time
these values are showed. The unit automatically switches back to RUN mode after 15 seconds have elapsed since
the last key press.
First SHIFT key pressing shows “MAH” in display followed by the maximum value, a second pressing now shows
“Min” followed by the minimum value and finally, a third pressing shows “run” to back again in an instant to RUN
mode.
RESET function activates when visualizing maximum or minimum values SHIFT key is pressed for at least 5
seconds. If maximum is the displayed value, current input signal value will replace the previous maximum saved
value. In the same way, current input signal will replace saved minimum value while is the minimum the displayed
value.
If 2RE output option is installed, it is possible to access to setpoints value
configuration without having to enter main menu.
To access this submenu, from RUN mode and after ENTER key is pressed, simply
press UP key while “Pro” is displayed.

To access this menu from RUN mode, press ENTER key for at least 3 seconds.
Display shows now “CodE” and then “0000”. Desired security code must be introduced
through SHIFT and UP keys (by default this code is 0000).
Finally press ENTER to begin with lock-out level configuration. If entered security code
is wrong, the instrument will go back to RUN mode.

Lock-out menu
The following configuration access can be locked-out:
 Setpoint 1 configuration (SEt1)
 Setpoint 2 configuration (SEt2)
 Input configuration (InP)
 Display configuration (dSP)
In each case lock-out is activated by selecting “yES” option and
deactivated by selecting “no”.
Setpoints 1 and 2 configuration lock-out is available only when 2RE
output is installed.
If 2RE output option card is uninstalled, the instrument keeps setpoints
last configuration in memory, though it can not be visualized. There will
be no need to reconfigure setpoints lock-out when 2RE output option is
again installed if the same configuration is required.
Once the instrument programming is completed, if there are
parameters that are going to be frequently changed, a partial lock-out
is recommended. A total lock-out is recommended when configuration
parameters will be constant for a long time.
Changing default security code and keep new one in a safe place is
also strongly recommended.

In order to prevent accidental or indesirable modifications of instrument parameters, a selective or total
configuration lock-out is available. By default the unit is delivered unlocked, giving access to all programming
levels. Once in this menu, the first option will be to choose between lock-out level setting (“LiSt”) or security
access code changing (“CHAn”).
If “LiSt” option is selected, display will show momentarily
“tLoc”. Total configuration lock-out is activated by
selecting “yES” option before the unit goes back to RUN
mode. When total lock-out is set, no data can be
entered or modified, although it will still be possible to
visualize all programmed parameters. Under these
conditions when entering main menu, initial indication will
be “dAtA” instead of “Pro”.
On the other hand, when “no” option is selected, routine
move on to next step to configure a partial lock-out.
When a partial lock-out is set, only non-locked data
can be entered or modified. Under these conditions
when entering main menu, initial indication will be “Pro”.

Description
OUTPUT OPTION
Function modes description
HI/LO mode activation
In HI mode, output activates when display value goes above setpoint level, whereas in LO mode, output activates
when display value falls below setpoint level.
Time delay
Time delay for OUT1 (HI mode) and for OUT2 (LO mode)
Asymmetrical hysteresis
Both output actions can be deferred by a hysteresis
level which is configurable in counts within full
available display. Decimal point position is the
previously defined in display configuration menu.
Asymmetrical hysteresis action only starts in the
output deactivation edge, obtaining as a result the
‘hys-1’ delay as indicated on the right figure.
Note that outputs activation is not affected by
hysteresis and they activate in each case just when
setpoint ‘SET’ is reached by display. Hysteresis delay for OUT1 (HI mode) and for OUT2 (LO mode)
2RE output option allows JR-E and JR20-E models to perform control operations and limit values treatment via ON/
OFF logic outputs. It is supplied as an independent card that is connected to main board without any additional
operation since internal software recognizes it once it is installed. There is no need to read the manual since all
information required is contained in this user manual.
Alarms are independent, they become activate when display value reach setpoint level programmed by the user.
For a correct configuration it will be necessary to define function mode, as well.
Both output actions can be deferred by a
configurable time delay from 0 up to 99.9 seconds.
Time delay activation starts when display value
reach each setpoint ‘SET’ in either increasing or
decreasing sense, obtaining as a result the ‘dly’
delay in output activation/deactivation as right
figure shows.

To physically install the output option, the electronics assembly should be first lifted out from the case. Use a
screwdriver or similar to slightly press both side tabs until the rear case is released. Then broke the junctions from
the corresponding polycarbonate cover in order to obtain the required orifice in the case. This orifice will allow 2RE
connectors come out through instrument rear part once it is installed.
Install 2RE option on the indicated location pushing slightly down until both connectors get perfectly together. For
best installation, it is recommended to solder this card to the main circuit making use of the copper pads on both
sides of its insertion pin and those surrounding the circuit hole where it is inserted in.
Once 2RE is installed, carefully put the circuitry again inside the case verifying that circuits slide properly without
much effort through rear case internal guides.
Each output card is supplied with an adhesive label that indicates wiring connections. To help identifying terminals,
this label should be placed in the upper side of the unit case. Besides its own connections, there are other output
options indications (option cards that can be mounted in other indicators models).
