Position proportional
output connections
Figure 2-14 shows the Output and Alarm wiring connections for models
with Position Proportional Output or Three Position Step Control (Models
DC330X-EE-XXX-X2, DC330X-AA-XXX-X2).
For Control and Alarm Relay Contact information, see Tables 2-7 and 2-8.
Calibration
Position Proportional Output or Three Position Step models must have the
output calibrated after installation (see Section 8—Position Proportional
Output Calibration) to ensure that the displayed output (slidewire
position) agrees with the actual final control element position.
Three Position Step models only require that the motor time be entered.
Full calibration is not required.
