Introduction

This is micro-controller based PID Controller Cum Process Controller. The instrument has three modes one is PID mode 2nd is re-transmission mode 3rd is Manual mode. User can select any one, suppose user select 2nd mode (Re-transmission mode) In this mode user can take 4-20mA output according the input. In the 3rd mode user can take 4-20mA by use key pad (manually) .The
upper display show process value and lower display show output value/Set point. The Instrument has Modbus (RS485) Communication And 2 Relay control.

How Can select Parameters

1st Press Prgkey for 3 seconds display inpts parameter in this parameter user can select any one input and press Ekey for nextparameters use upkey and pervious parameter use dnkey . User can select any parameter by use upkey/dnkey . Exit Parameter, in this parameter if press E key then exit from programming mode.

PID Control Mode

• In this mode use following parameters:
  1.Type = PID
  2. pdly = Pid delay time (1 value = 1MS)
  3. Action parameter use for PID action forward/Revere mode
  4. SP– = PID set point.
  5. dEtd = Derivative value of PID Control action slow /fast(0-3000).
  6. Intr : integral value of PID Control (0-3000).
  7. Pd– : Proportional gain value of PID Set point(0-999.0)
  8. dbnd : dead band % value of Set point( dead band= set point x dbnd%)

For fast action of PID control: then increase integral value & decrease derivative value and
adjust the value of proportional gain. For slow action of PID Control: adjust (increase ) derivative value & decrease integral value
and adjust proportional gain & derivative value

dbnd :
In this parameter the percentage higher and lower side of the set point is defined so that when the PID reaches the process value around the set point, the dead band comes into action at that time and which is the value of the dead band if the process value is within
that limit. So there will be no action on the control. And if the process value is more than the dead band value then the PID controls action will take place otherwise no action will be taken due to being in dead band.

SP–: In the running mode, if user press upkey + Prgkey then display set point press Ekey and set desired value by use up/dnkey and press Ekey

Auto/Manual Mode

First hold down the enter key and then press the prg key after which the instrument will automatically go into manual / auto mode. If earlier it is in AUTO mode then it will go in manual mode and if in manual mood then it will go in AUTO mode.

By pressing and releasing the enter key, the user can check whether the instrument is in auto mode or manual mode.Display: in the display parameter, the user can define whether he want to show the set point value on the SV display or show the PID control value. If select outP then display pid control output or if select SEtP then display PID set point value.

Process Indicator cum Controller(Mode2): In this mode user can be use the instrument as a process indicator / controller and take 4-20mA retransmission output .

K-Factor

This K-factor will be given in terms of the number of pulses produced by the sensor/meter for a given volumetric flow. (e.g) 150
pulses per liter etc. This K-factor is the value that is entered into a batch meter or indicator/totalizer in order to give readout in engineering units.

Example 1

Example 1 : If the display on a flow rate meter is required in U.S. gallons per second, and the K-factor of the flow meter is 210 pulses
per U.S. gallon, then the K-factor entered into the rate meter would be 210. If a totalizer associated with the same flow meter was to be
set up so as to flow rate in U.S. gallons the indicator K-factor would be 210. If the indicator was to be set to flow rate in tenths of a
gallon the K-factor would be 210 /10 = 21, 21=K-factor Note: If user need to flow value in tenths of a gallon/Liter then
value of K factor = 21 set in factor parameter and k_decimal point set zero. If user needs to show flow value in ones then 210 value set
in factor parameter and k_decimal =0 .

Note for K-Factor

Note-For K-factor : Press Prg key display input parameter press E key and select puls input by up( )/dn( )keys after selection press Ekey now again display inpt now use up key for select for next parameter Fctr(kfactor) press Ekey now display last loaded value of k_factor,If you want change value then use up/Dnkey according your k_factor value (Like 225/22.5) now press & hold Prgkey after 1 seconds press E key now release both keys then display dP(Decimal Point) Press Ekey set decimal point according your k_factor value and Press Ekey now again display Fctr (it means K-factor value has been store)

Calibration

Press and hold Dnkey + Prgkey for 5 seconds then display “Zero” now apply 0mA at input terminal(+10 &-11) after that press E key now display ADC value counts wait for 3 seconds then press and hold Prgkey after 1 seconds press Ekey and now release both key ,Display CALL (Low calibration) now apply 4mA at input terminal (+10 & -11) after that press Ekey Now display ADC counts wait for 5
seconds then Press and hold Prgkey after 1 seconds press E key and now release both keys, Display CALH(High Calibration) now apply 20mA at input terminal(+10 & -11) after that press E key now Display ADC counts wait for 5 seconds then press and hold Prgkey
after 1 seconds press E key Now calibration complete . Note after calibration parameter SPANL/SPANH must be redefine

Faults & Errors

Faults/Errors:
1. Err1:
2. -Err:
3. Open:
4. Undr
5. over

Err1: If the instrument is showing error1, then the internal data of the instrument has been corrupted in this error, now it has to be defaulted. The defaultvalue to be loaded in internal memory through for the following process. 1st switch power of the instrument power after press & hold Dnkey + Upkey then power switch on of the instrument after 10 seconds releases both key, Now instrument must be reconfigure and recalibrate .

-Err: If the instrument is showing -Err, it means input terminal connection is reversed. So please change input terminal connection (+10 / -11).

Open: input terminal wire disconnected or input source has been faulted.
Undr : input value low then 4mA/1VDC.
Over : input higher than defined range setting.
