SIR MAY I KNOW IF RADAR TYPE LEVEL TRANSMITTER SHOWING IN
THE FIELD 0 % LEVEL AND IN DCS SHOWING 100% THEN WHAT IS THE
CAUSE I CLEAN THE CHAMBER & TAKEN ONLINE BUT ONLY ONCE ITS
BECOME ZERO IN DCS BUT AGAIN 100% SHOWING IN DCS,THEN I
REMOVE THE POWER SUPLLY AND CONNECT IT AGAIN .IS IT OK BUT
STILL IN THE DCS ITS 100% AND ON THE DISPLAY ITS
INITILAZIATION PLEASE HELP ME READRING THIS?

Firstly, you should use a loop simulator and simulate the
Milliamp range to the dcs 0 to 20 or 4 to 20 do this in 25%
steps.If the dcs responds to the signal then the problem is
with the radar transmitter. If the problem persists when
simulating the the problem is on the Input card. Could be a
zero volt issue, a faulty input card or a wiring issue
could even be software related. To remedy the radar if that
is deemed faulty then consult the manual, you might need to
adjust parameters or do mapping of the vessel when it is
empty. Hope this helps

Answer / prakash malviya
first u have 2 remove o/p wires of 4-20 ma then connect ma source with parellel this.then give 4& 20 ma...at 4 u see 0 %lvl & at 20 u find 100% lvl in dcs.if can't then u have 2 check from dcs side.in dcs check AI card particular channel for this.check wires grounding.
2nd condition if u find proper response in dcs with ma given to o/p wires..then go to the radar menu ..go to configuration..in that u find tank lvl...select full...then save it..

WHAT IS A SYMPTOM OF FAULT WITH THE SPAN OF AN INSTRUMENT? 1)ZERO-POINT AND 100% ARE CORRECT BUT NOT A MID-RANGE. 2)ZERO-POINT IS CORRECT ,BUT 1005 INPUT IS NOT GIVING 100% OUTPUT. 3)LINEARITY PRBS. 4)1005 O/p IS CORRECT BUT ZEO POINT IS WRONG.
pt range is -45 psi to 45 psi.friends can you give answer with calculation and with linerity scale like 0%,25%,50%,75%& 100%?
why we use only 4 to 20ma other than 0 to 16 ma
