H) Fail Close, Fail Open and Fail Stop Setting
The PCU card will recognize input signals such as no signal or wrong signal as faults, it will m
ake the actuator automatically move to fully OPEN or fully CLOSE position, or the actuator will
STOP immediately in the current position.
I) Auto Full Action (A FULL)
Dip switch No. 3 (A_FULL) is in the ON position as shown above.
This setting will make the actuator run to the fully closed position if
the input signal is lower than 4.3mA. It will run to the fully open
position if the input signal is higher than 19.7MA
J) Reverse Mode
- When the Reverse Mode is set as shown on the picture on the
right, the actuator is responding in reverse to the input signal.
This means:
- When input (command) signal is 4mA, the actuator will run to the
fully open position and will send out 4mA as output signal
(feedback).
- When the input (command) signal is 20mA, the actuator will run
to the fully closed position and will send out 20mA as output
signal (feedback).
K) Setting the Optional Set Point
• ZERO (FULL CLOSE) Signal, SPAN (FULL OPEN) Signal for changing the Signal
• ZERO (FULL CLOSE) Signal SETTING Range: Generally 3 ~ 8 mA DC
• SPAN (FULL OPEN) Signal SETTING Range: Generally 16 ~ 21mA DC
Example
Please set full close (zero) to 5mA DC and set fully open (span) to 19mA DC
① Put dip switch No. 4 ON (SW3).
② RED & GREEN LED start blinking together.
