Positioner PEPC-10

 

APPLICATION

* The positioner controller PEPC - 10 is used in connection with a pressure transmitter potentiometer and Servo motor drive feedback potentiometer    to modulate the firing with respect to the boiler Set pressure.
* Up to three positioners controllers can be controlled from one pressure transmitter potentiometer .

 

INSTALLATION

* The positioner controller can be mounted in any position in a dry location, e.g control panel.
* The version for line voltage (e.g. 220v- or 110v-) has to be protected against accidental touching of live parts
* For panel or wall mounting the controller has to be built into the housing.

ELECTRICAL CONNECTIO0N

* Before connection the unit it has to be checked, if the available supply voltage corresponds with the voltage Given on the positioner lable.
  (e.g. 220v- or 110v-)


OPERATION

* The positioner controller PEPC 10 is a P - controller. The position of the pressure transmitter potentiometer GW (0% - 100%) is compared with the position of the burner feedback potentiometer R W (100% - 0%) built Into the servo motor drive. When a deviation exists in the transmitter potentiometer the positioner controller.
Give the corresponding control signals to the motor drive until the position balance is established.
Transmitter and feedback potentiometers with a nominal value form 130 to 2000 ohms can be used.

 
 

OPERATION

* Switch on installation
* Run transmitter drive in to one limit position (0%) i.e. connect manual potentiometer to 11,13, & 14 of PEPC - 10 Equal to transmitter    potentiometer value.
* Check if servo motor drive runs into the other limit position. (100%) or High Flame.
* Run transmitter drives into the other limit position (100%) and cheek the Servo motor drive run to Low Flame.
