D104239X012
LOCAL – hands on operation at the actuator by manipulation of Control Knob.
REMOTE – used within the context of plant operation, i.e. Remote Control Panel, PLC, DCS, etc. See wiring diagram for
typical user wiring for remote control.
OFF (Stop) – to prevent local or remote operation.
Figure 7.

Local Operation

Place the "Selector Knob" in the "Local" position. If a remote display is connected, the remote selector switch must not
be in the "Off" position. Verify that the selector "L" amber light is on. The actuator may now be operated using the
port and jog Control Knobs. Jog control is normally disabled and must be enabled in the setup menu.
To jog or micro-step the actuator toward the next port, rotate the control knob in the counterclockwise direction. Jog
to position and release when the desired position is reached. When using jog for calibrating the actuator, always stop
short of the desired port and use the hand wheel to complete accurate positioning to center of the port.
To move only to the next port, momentarily rotate the control knob in the clockwise direction to the Port position and
release.
To Stop or prevent actuator movement, move Selector knob to the OFF (Stop) position.

Operational Display

Operational indicators for RUN / ALARM / PORT position use long lasting LED's. Run torque and port position are
shown on the digital readout during normal operation. Torque in percent of maximum is displayed as a 2-digit number
only while the motor is running. Port position is displayed as a single digit when the motor stops. If the actuator stops
between two ports, the two corresponding port numbers will alternate. Torque less than 10% is displayed as 0%.
RUN LED flashes Green while the actuator is moving to the next port and flashes Red while running within 2° of the
selected port position.
