DYNAMIC SELF BALANCING

CONTROL VALVE

FlowCon SM with BACnet actuator

- 2 -

Programming

of the actuator through BACnet.

Please note that change of settings through

BACnet is not available while one of the

menus is entered on the actuator itself.

In this instruction:

AV = Analog Value

BV = Binary Value

MSV = Multi-State Value.

Default values are underlined.

Choose which valve the actuator is mounted

on in MSV.38 (programming menu step 2).

Options:

1 = SM.0.0 (no valve)

2 = SM.1.1

3 = SM.2.1

4 = SM.3.0

5 = SM.3.1

6 = SM.3.2

7 = SM.4.1

8 = SM.4.2

9 = SM.4.3

10 = SM.5.1

11 = SM.5.2

Choose relevant unit in MSV.39

(programming menu step 3).

Options:

1 = l/sec

2 = GPM

3 = l/hr

Choose operational direction in BV.17

(programming menu step 10).

Options:

0 = NO (normally open)

1 = NC (normally closed)

Choose maximum flow rate in AV.62

(programming menu step 9).

The input will automatically be rounded off to

the nearest available maximum flow rate for

the chosen valve. Please see the relevant

tech note for information about the maximum

flow rates available for each valve.

Choose control signal type in MSV.40

(programming menu step 5).

Options:

1 = V

2 = mA

3 = digital (2-position / 3-point-floating)

4 = BACnet

If MSV.40=1 (V) or MSV.40=2 (mA), please

check control signal range. Choose minimum

value for the control signal in AV.138 (pro-

gramming menu step 6) and maximum value

for the control signal in AV.139 (programming

menu step 7). The range must be at least

3.0V respectively 6.0mA and maximum ran-

ges are 0-10V respectively 0-20mA.

If MSV.40=4 (BACnet), please choose BAC-

net fallback timeout in AV.143 (options: 1-60

minutes, defalult:10) and BACnet fallback

action (options: 1=close, 2=stop, 3=open,

4=midway) in MSV.43 to define the action to

be taken if the actuator does not get a value

for the control signal within the timeout period

since the last time it received a control sig-

nal. Administrating the control signal through

BACnet is done by writing the present-value

of AV.141 in the range of 0.0-100.0%.

Choose feedback signal type and range in

MSV.41 (programming menu step 8).

Options:

1 = 2-10V

2 = 0-10V

3 = 4-20mA

4 = auto

Option 4 is only available and default if control

signal type is V or mA (this option sets feed-

back signal type and range to the same as

control signal type and range). If control signal

type is digital or BACnet, option 1 is default.
