Risk of Electric Shock.
Do not touch any exposed metal parts with anything
other than properly insulated tools or insulated probes
of the digital voltage meter. Failure to use properly
insulated tools and probes may result in severe
personal injury or death.
Setting the SPAN and OFFSET Proportional
Command Signal to Other Values
1. Set DIP switch one and two before proceeding.
See Figure 14 for DIP switch placement.
2. Connect a digital multimeter between the orange
(feedback) and black (common) wires. See Wiring
for more wiring information.
3. Press Enter/Autocal.
To adjust the span and offset, press but do not hold
Enter/Autocal. Holding Enter/Autocal for longer
than 3 seconds triggers an autocal.
The Offset Adj. LED turns on, and the multimeter
displays the current offset value.

4. Press INC.
The Offset Adj. LED flashes. The voltage reading
on the multimeter increases 0.5 VDC each time
you press the button. Press INC. until you reach
the desired voltage.
If no further action is required, the Offset Adj. LED
stops flashing after 10 seconds. The actuator exits
the program mode, and the original offset value
remains unchanged.
5. Press Enter/Autocal.
The Offset Adj. LED turns off indicating that the
desired Offset Adj. value was recorded. The Span
Adj. turns on, and the multimeter displays the
present SPAN value.
6. Press INC.
The Span Adj. LED flashes. The voltage reading on
the multimeter increases by 0.5 VDC each time
you press the button. Press INC. until you reach
the desired voltage.
If no further action is required, the Offset and Adj.
LED stops flashing after 10 seconds. The actuator
exits the program mode, and the original offset
value remains unchanged.
7. Press Enter/Autocal.
The Span Adj. LED turns off indicating that the
desired Span Adj. setting is saved, and the
actuator exits the program mode.
Reading the SPAN and OFFSET Proportional
Command Signal Voltage Settings
1. Connect a digital multimeter between the orange
(feedback) and black (common) wires. See Wiring
for more wiring information.
2. Press Enter/Autocal.
The Offset Adj. LED turns on, and the multimeter
displays the current offset value.
IMPORTANT: Do not press INC. Otherwise your
observed offset voltage setting changes.
3. Press Enter/Autocal.
The Offset Adj. LED turns off, the Span Adj. LED
turns on, and the multimeter displays the present
SPAN value.
IMPORTANT: Do not press INC. Otherwise your
observed SPAN voltage setting changes.
4. Press Enter/Autocal.
The Span Adj. LED turns off.
