Operating Manual fo rLarge Display Board
Jumbo-200 Series
3-Line, 8”, 4-20mA Input
SECTION 4: Putting into OperationPower up the online display as per its wiring diagram given in another section in this manual and refer this
drawing while understanding this operational manual.
Connect the 4-20 MA DC input from field Transmitters at terminals marked for the same as per Wiring andTerminals diagram.
4 keys are provided on individual CPU card of each display for changing range and/or calibration checks,
SECTION 5: Programming the individual disp lays As the instrument is a current indicator, the input programmed is mA input.
The instrument’s operation is described in 2 modes as follows :
Configuration Mode - Use this mode to re-configure the instrument range.
Calibration Mode - Use this mode to check the calibration or recalibrate the instrument.
IMPORTANT NOTE: WHEN MULTIPLE KEY FUNCTIONS ARE REQUIRED, THE FIRST KEY IS TO BE PRESSEDFIRST, AND KEEPING IT PRESSED, THE SECOND KEY HAS TO BE THEN PRESSED, TO GO INTO THEPARTICULAR MODE.
Eg.: When S + E key press instruction is given, Press S key first, and keeping it pressed, press the E key, then releaseS key first and lastly release E key to get into the calibration mode.
Operation Mode Pushbuttons on CPU Board Display normally showsNormal DisplayJUMBO-151 normally displaysthe process value on its 3-digitdisplay. In case sensor/input isopen or not connected, displayshows OPEN.If process value exceeds 20 mAdisplay Starts blinking ,same isthe case if value goes bellow4mA

What is it’s function?In this mode the user can changeinstrument’s input, resolution(decimal point), To get into thismode press
S + E keys first.
Press S + together.
Instrument shows the inputconfigured at present.
By using , keysselect required input.
Get out of the mode bypressing S+E keys again.
Step1: Press S + E keys.
Step2: Press S + keys.
Step3: Press or keys toselect desired input.Eg.: mA
Step4: Press S key to selectRANGE HI.Step5: Press S key to selectRANGE LOStep6: Press S key to selectdecimal point
Step7:Press or keys toselect desired dpStep8: Press S key to select serial-numberStep9: Press S key to select
Step10:Press or keys toselect desired serial number
Display shows ZERO.mA input (linear mA DC)Display shows input typeFor eg. mA…..).
Display shows rngH and 100on again pressing S.
Adjust to 100 or requiredvalue of input transmitter by
& keys.
Display shows rngL and 000
on again oressing S. Adjust to000 by & keys.
Press S, display shows DpDisplay shows PV e.g. 000
Set decimal by &
Display shows SrnO (eg 001)(communication serial

Input Calibration Mode Keyboard Operation ExampleWhat is input calibration mode?In this mode user can check or re-calibrate the JUMBO-151 at site.To get into this mode, press1. S + E keys first.2. Press E key successively toselect ZERO and SPAN, ensuremA input is configured forinstrument).
3. Get out of the mode by
pressing S + E keys again.
Connect required calibration source(mA) at the input terminals.1. Press S + E keys. Display
shows ZErO.2. Press E key to see input at
ZERO calibration side.
3. Press OR keys to adjusterrors if any.4. Press E, displays SPAn.5. Repeat calibration for
SPAN, give full span input
and adjust error byOR keys.
Example given below is for anmA input configured JUMBO-151.
ZErO (Zero side inputcalibration).001 (mAinput at zero mAwith an error of 1)000 (error 1 corrected)
SPAn (Span side input
