(*) There are nine switches in a row on the
circuit board. The factory shipped
default switch positions are all “OFF.”
1 Valve Closing Screw
Upon power up with switch 1 OFF the
actuator will fully retract before the input
control signal takes control. If switch 1 is
ON the actuator will fully extend before
the input control signal takes over. This
switch will change the proportional or
floating input signal to direct or reverse
action similar to switch 7
2 Control signal—Prop / Float
TAC Forta can either be controlled by a
Proportional signal (SW2 OFF), or a
floating signal (SW2 ON)
3 Sequence or parallel control—
– – – / SEQ
With sequence (or parallel) control (SEQ),
two actuators/valves can be controlled by
only one proportional control signal.
Switch 2 must be OFF, switch 3 must be
ON and switch 5 will configure the range.
Note if sequence or parallel control is not
used switch 3 must be in the off position
4 Voltage range
You can choose whether to use the control
signal voltage range 0-10Vdc (SW4 off)
or 2-10Vdc (SW4 on).
5 Part of voltage range—
0-5, 2-6 / 5-10, 6-10
Allows you to select 0-5/2-6v or 5-10/6-
10v working range.
If SW5 is OFF the 0-5/2-6v range is
selected, If SW5 is ON the 5-10/6-10v is
selected
Note switch 5 is only active if switch 2 is
OFF and switch 3 is ON.
6
If switch 2 is ON SW6 controls run time,
SW 6 OFF equals 60 sec, ON equals 300
sec run time.
7 Direction of movement—
NORM / INV
Changes the proportional or floating input
signal to direct or reverse action similar to
switch 1
8 Linearization
SW 8 OFF normal
SW8 ON Linear electronic control
The motorized valve characteristics can
be modified. If you wish for the
characteristics to be affected, the
setting LIN/LG will make the characteristics
of an equally modified percentage (EQM)
valve almost linear.
On the other hand, with LIN/LG setting a
motorized valve equipped with a linear
valve will operate with ”Quick open
characteristics.”
Note!
For the actuator to register
new settings of the switches, the
supply voltage must be removed by
cutting power to the actuator or
lowering the manual override lever,
then change any of switches one
through 8 as required and then
restore power to the actuator or raise
the manual override level.
Please refer to illustration on page 2,
figure 2.
Note: After mounting the actuator on a
valve, dipswitch 9 must be momentarily
switched off to on to off with the actuator
powered for proper actuator valve
stroke calibration.
9 (OP/ADJ)
Input Signal/Stroke calibration SW9 OFF
normal operation
This switch is only used to calibrate the
input control signal and the valve stroke.
To calibrate, power to the actuator must
be on, momentarily turn switch 9 on and
then off. The actuator will automatically
match the control input signal to the valve
stroke (switch 9 must be left in the off
position for normal operation).
