APPLICATION * The positioner controller PEPC - 10 is used in connection with a presssure transmitter poteniometer and Servo motor drive feedback poteniometer to modulate the firing with reespect to the boiler Set pressure. * Up to three positioners controllers can be controlled from one pressure transmitter poteniometer . |
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 avaibilable supply voltage corresponds with the voltage Given on the positioner lable. (e.g. 220v- or 110v-) .OPERATON * 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. |
