The settings of Zero and Span have been calibrated at the factory. However, if re-calibration is required, proceed as follows:
Use the hand wheel to drive the actuator to a half open position.
Apply power (or use the manual override) to drive the actuator to its
fully closed position (clockwise rotation).
When the actuator is in the fully closed position, adjust the ZERO dial on
the CPT board until a reading of 4mA is achieved.
Apply power (or use the manual override) to drive the actuator to its fully
open position (counter-clockwise rotation).
When the actuator is in the fully open position, adjust the SPAN dial on the
CPT board until a reading of 20mA is achieved.
4.6 Proportional Control Unit (PCU-A)
PCU-Rev-4 High Performance Controller, using 10 bit A/D converter and 8bit microprocessor technology.
The factory settings of the PCU card are
normally set according to the customer
requirements at the time of order. However, we
strongly recommend that input power, signal input
selection and dip switches are to be verified prior to
the actuator start up.
!
CAUTION: HAZARDOUS VOLTAGE. TURN OFF ALL POWER BEFORE SETTING YOUR ACTUATOR.
4.7 Proportional Control Unit (PCU-D)
