3.8.
Using the UP and DN buttons under the cover, adjust the output pressure to the highest
desired pressure.
3.9.
Apply the desired control voltage to the V input terminals for this pressure setting.
3.10.
Press the SET button and wait for the Limit Lo LED to turn from Green then Red and back to
Green to set the high travel limit and corresponding control current.
3.11.
Position the SETUP switch to the OPERATE/ANALOG to operate the actuator from the V input
terminals.
3.12.
ERROR SIGNALS
–
If both the Hi Limit and Lo Limit LED’s blink red, then an error has occurred
in setting the Analog Control signal. The most common error is setting the Lo and Hi Limit and
forgetting to change the control voltage. In this case, the Lo Limit and Hi Limit are set with the
same voltage. This signal also occurs if the difference in control current between the Lo Limit
and Hi Limit is less than 1 volt. Correcting either the Lo Limit or Hi Limit setting or both will
resolve the problem.
