INSTALLATION AND OPERATION INSTRUCTION
FlowCon SM 50-150mm, 2”-6”
Install the FlowCon SM valve either in the
supply or return pipe work for the unit. It is
recommended that a strainer be installed
prior to the valve body to prevent damage or
blockage due to debris. INSTALL THE VALVE
HOUSING WITH THE FLOW DIRECTIONAL
ARROW POINTING IN THE CORRECT
DIRECTION.
The valve body is available for double flange
connections, i.e figure 1.
O-rings are supplied with the valve body and
are used to seal the connections. Pls. make
sure these are in place in the o-ring grooves
in the inlet and outlet of the valve body, when
installing the housing.
recommended to grease the o-rings with
It is
a silicone grease before installation.
IMPORTANT: Never use mineral oil or petrol
based grease or oil on the o-rings.
Valve bodies are as standard supplied with
pressure/temperature fittings (p/t plugs).
Before finger mounting the p/t plugs in the
body tappings, please seal the threads of the
p/t plugs (DO NOT OVER TIGHTEN).
Fitting and orientation
of the actuator
Pls. install the valve so that the actuator
is located upwards and not lower than the
horizontal line to prevent condensation into
the electronics (pls. see figure 2 next page).

WRONG:
Condensate can drip off the
shaft adapter into this support 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 components when programming your actuator. Set
the maximum flow DIP switches (refer to tables
on page 6-8). If adjusting the DIP switch settings after power has been connected, press
the reset button to input the new setting.
Figures 5-9 illustrate the different signal requirements, i.e. Analog 2-10V, Analog 4-20

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 connected 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).
