Figure 3
WRONG:
Condensate can drip off the
shaft adapter into this sup-
port of the mounting bracket,
gathering until it leaks into the
actuator.

Valve and actuator mounting components and
tool are shown in figure 3.
Actuator wiring and programming
Remove the actuator cover by loosening the
cover screw. Figure 4 illustrates the actuator
circuit board layout and all relevant compo-
nents when programming your actuator. Set
the maximum flow DIP switches (refer to tables
on page 6-8). If adjusting the DIP switch set-
tings after power has been connected, press
the reset button to input the new setting.
Figures 5-9 illustrate the different signal re-
quirements, i.e. Analog 2-10V, Analog 4-20
mA, Pulse Width Modulation and Digital Tri-
state and how to apply resistors and wires.
Connect the wiring according to the selected
input signal.
500ohm resistors (the blue ones) are supplied
for 4-20mA to 2-10V conversion and connect-
ed as illustrated in figure 5 (2-10V) or figure 6
(4-20mA).
Two 2.2Kohm resistors (the brown ones) are
supplied for special consideration for digital/
tri-state control. In this mode the actuator is
sensitive to induced electrical voltages from
other sources. To prevent such interference,
wire one 2.2Kohm resistor between pins 1 and
4 and the second 2.2Kohm resistor between
pins 1 and 3 (see figures 8 and 9).
