The actuator is factory preset for an ana-
log signal. If the signal requirement must be
changed, proceed with the instruction below:
Remove power and set all
programming DIP switches
to OFF.
Apply power and within 10
seconds, press and
release the reset button.
The programming and
indication LED should
start blinking.
Turn programming DIP switch #1, #2 or #3 ON,
then OFF to select signal requirement.
Switch #1:
Digital/3-Point-
Floating/Tri-state.
Switch #2:
PWM Pulse
Width Modulation.
Switch #3:
Analog
2-10V or 4-20mA.
Normally Open or
Normally Closed function setting
The actuator is delivered from factory set to
Normally Closed and an analog control signal
so that a minimum signal of 2V or 4mA will
close the valve and maximum signal of 10V
or 20mA will open the valve to selected maxi-
mum flow. If changing to Normally Open, see
below:
For Normally Open set
programming switch #1 to ON.
For Normally Closed set
programming switch #1 to OFF.
Failsafe Open or
Failsafe Closed function setting
This function applies to battery back up fail-
safe models only. It provides power storage to
drive the actuator either open to the maximum
flow setting or fully closed in the event of a
power supply failure. As standard the actuator
is set to Failsafe Closed.
For Failsafe Open set
programming switch #2 to ON.
For Failsafe Closed set
programming switch #2 to OFF.
PWM time base resolution setting
This function applies only if the actuator has
been programmed to accept a pulse width
modulation (PWM) signal. If with PWM,
standard setting is 0.1 to 25 second/100mS
resolution.
For 0.1 to 5 second/20mS
resolution set programming
switch #3 to ON.
For 0.1 to 25 second/100mS
resolution set programming
switch #3 to OFF.
Actuator Zero and Span adjustment
Remove power from the actuator. Re-apply
power to terminal 2 and
within 10 seconds, press
and hold the reset button
until the indication LED
blinks once.
Release the reset button.
The indication LED should
remain illuminated.
