ELECTRONIC POSITIONER MODEL - PP300
electronic-positioner

PP300 is an electronic positioner designed for use with Electrical Actuators. Being a microcontroller based positioner it can achieve high levels of accuracy compared to conventional Analog Positioners. It accepts 4-20mA dc current / Potentiometer (100/235E) as feedback signal. PP300 provides field configurable features through dipswitches and trim-pots, apart from providing status indication LEDs making it easier for operators.

FAIL AS IS

Positioner will Withdraw an active command & waits till signal is restored

dip-wsitch

FAIL OPEN

Positioner gives an OPEN command

dip-wsitch

FAIL CLOSE

Positioner gives a CLOSE command

ELECTRONIC POSITIONER WITH DISPLAY(PANEL MOUNTABLE)MODEL: PP503

PP503 is an electronic positioner designed specifically for use with Electrical Actuators. Being a microcontroller based positioner it can achieve high levels of accuracy compared to conventional Analog Positioners. This Positioner accepts 4-20mA/Potentiometer(100-235E) as feedback signal. It can also be configured to control manually using push button switches. It has an Output F/B which transmits 4-20mA proportional to the feedback signal. PP503 provides field configurable features through dipswitches and trim-pots, apart from providing status indication LEDs making it easier for operators.

SEVEN SEGMENT DISPLAY - To Display the Percentage Opening of valve with a resolution of 0.1%.
POSITION INDICATORS  
OPEN LED - Indicates the valve is currently opening.
CLOSE LED - Indicates that the valve is currently closing.
POSITION OK LED - Indicates FB has matched the COMD Signal and the Valve is stationary.
SIGNAL FAIL LED - Indicates a loss of FB or COMD signal.
POSITIONER CALIBRATION :  
ZERO/SPAN TRIMPOTS - To calibrate the positioner against the command signal.
DB/TD TRIMPOTS - To adjust Dead band and Time Delay respectively.
DISPLAY CALIBRATION :  
ZERO AND SPAN TRIMPOTS - To calibrate the instrument display with the feedback signal.
DIPSWITCH :  
1.AUTO /MANUAL

- ON : Manual Mode Operation

OFF : Regulating Duty Mode Operation.

2.CURR F/B

- ON : 4-20mA Feedback.

OFF : Potentiometer Feedback (100 -235E).

3. CURR F/B

- ON : 4-20mA Feedback.

OFF : Potentiometer Feedback (100 -235E).

4.POT.F/B

- ON : Potentiometer Feedback (100 -235E).

-OFF : 4-20mA Feedback.

5.FAIL OPEN

- ON : On Signal Fail , Actuator goes to OPEN .

OFF : On Signal Fail , Actuator stays As Is .

6.FAIL CLOSE

- ON : On Signal Fail , Actuator goes to CLOSE.

OFF : On Signal Fail , Actuator stays As Is.

OUTPUT CURRENT CALIBRATION:  
ZERO/SPAN TRIMPOTS - To calibrate output current signal against the feedback signal.
Note: Output Current Signal is proportional to the feedback signal and is not isolated.
MANUAL MODE CONTROLS:  
Manual controls will be activated only if the positioner is configured to work in the MANUAL MODE by selecting the
DIPSWITCH. These switches permit valve movement irrespective of the Feedback signal given.
OPEN - Sends OPEN signal to the valve in Manual mode.
STOP - Sends STOP signal to the valve in Manual mode.
CLOSE - Sends CLOSE signal to the valve in Manual mode.
AUTO LED - Indicates that Positioner is configured in AUTO mode.
MANUAL LED - Indicates that Positioner is configured to work with MANUAL controls.
