LIGHTS AND DISPLAY

Eg.2
-- Running light (RUN): When the actuator stem retracts, the running light shows red; when the actuator stem extends, the running light shows green;
When the actuator is self-stroking, the running light flashes red (1Hz). The display does not show a value when the actuator is self-stroking.
-- Warning light (ERR): When the actuator has an error, the warning light will be lit. Errors include: The actuator cannot complete the self-stoking function.
The actuator cannot move the stem to the correct position for the input signal.
-- Display: The display has two parts. The first part, the single character on the left, is the function display; the second part, the three characters on the
right, is the numerical display.
DESCRIPTION OF DISPLAY:

display
shows Meaning
A Numerical display shows aperture
setting in percent Number
from
30~100 Function display shows A and numerical display shows value from 30 to 100 as
aperture potentiometer is turned. The aperture value MUST be set to 100 (Factory
Default). If the aperture value is less than 100 the valve will not function properly
as a PICV.
C Numerical display shows input
signal in percent Number
from
0~100 Input signal percent. Example: For input signal 0~10V, when input signal is 1 V,
display will show 10 (1/10*100=10)
F Numerical display shows output
signal in percent Number
from
0~100 Output signal percent. Example: For Output signal 0~10V, when output signal is 1
V, display will show 10 (1/10*100=10)
When the actuator is running correctly, “C” and “F” alternate in the function display. When “C” is visible, the input signal percentage is shown in the
numerical display. When “F” is visible, the output signal percentage is shown in the numerical display.
Additional function terminal
1) Terminal 1,2 (UL): Non-functional, No terminal block present
2) Terminal 3,4 (DL): Non-functional, No terminal block present
3) Terminal 5,6 (AL): Fault SPDT input terminal (NO) When a fault occurs, this terminal will close. Faults include: The actuator cannot complete the self-
stoking function. The actuator cannot move the stem to the correct position for the input signal.

Description
S2-1
Start point of
input/output
signal
ON 20%: The start point of the input / output signal is 20% (The full input / output
signal is 4~20mA or 2~10V) (Factory Default)
OFF 0: The start point of the input / output signal is 0% (The full input / output signal is
0~20mA or 0~10V)
S2-2
Type of input
signal ON II: Input signal is current (mAdc) (Factory Default)
OFF UI: Input signal is voltage (Vdc)
S2-3
ON When S2-2 is OFF, S2-3 MUST be ON
OFF When S2-2 is ON, S2-3 MUST be OFF (Factory Default)
S2-4
Type of output
(feedback)
signal ON IO: Output signal is current (mAdc) (Factory Default)
OFF UO: Output signal is voltage (Vdc)
S3-5
Operating
mode
ON DA: DA mode (When input signal is increasing, the actuator stem extends ) (Factory
Default)
OFF RA: RA mode (When input signal is increasing, the actuator stem retracts)
S3-6
Loss of input
signal mode
ON DW: On loss of input signal, the actuator fails to the minimum input signal position.
(Factory Default)
OFF UP: On loss of input signal, the actuator fails to the maximum input signal position.
S3-7
Self-stroking
mode
ON DF: Self-stroking starts each time the actuator is powered up.
OFF RF: Self-stroking starts ONLY when the self-stroking button is pressed for >3 sec-
onds. (Factory Default)
S3-8 Sensitivity
ON HS: High sensitivity of input signal </=1.5%
OFF LS: Low sensitivity of input signal </=2% (Factory Default)
