DYNAMIC SELF BALANCING

CONTROL VALVE

FlowCon SM with BACnet actuator

- 3 -

Choose whether or not to enable flush at

startup in BV.53 (programming menu step 4).

Flush enabled results in the actuator open-

ing the valve almost fully if no control sig-

nal is registered at start-up.

This function is only available if control signal

type is V or mA.

Options:

0 = disable

1 = enable

Choose whether or not to enable password

protection of the actuator in BV.54 (program-

ming menu step 11).

If password protection is enabled, the actua-

tor requires a password to enter the program-

ming menu via the buttons on the actuator.

Options:

0 = disable

1 = enable

If the actuator is of the type SM.0.0.0.6

(failsafe and BACnet), please choose the

direction of the failsafe action in BV.18

(programming menu step 12).

Options:

0 = open

1 = close

Please note, that the settings and values can-

not be altered through BACnet while the alarm

menu or the programming menu is entered

on the actuator.

Condition of the

actuator through BACnet.

Besides checking the values of the objects

already described, the following information

is available through BACnet:

Check the current flow rate (not measured)

in AV.68. If AV.68=0, the flow rate is less

than the minimum defined flow rate (for in-

formation about minimum defined flow rate

please see the tech note, which is always

available at www

.flowcon. com).

T

o know whether the valve is fully closed,

please check the motor position in AV.98, if

AV.98=0% the valve is fully closed.

Check the appropriate pressure range in

MSV.44. Values:

1 = NA

2 = 32-320kPaD

3 = 40-320kPaD

4/5/7/10 = 35-400kPaD

6 = 80-400kPaD

8/9/11 = 60-400kPaD

Check the actuator state in MSV.45.

Values:

1 = normal operation

2 = calibration mode

3 = flush mode

4 = auto-stroke

5 = alarm (at least one alarm has been

activated)

6 = failsafe (failsafe action has begun)

If MSV.45=5, please check for any alarms in

BV.55 - BV.62.

Values:

0 = no alarm

1 = alarm activated

If MSV.40=1 or MSV.40=2, check the con-

trol signal value in AV.141. If MSV.40=3,

check the control signal in MSV.42.

Check unit and value of the feedback sig-

nal in AV.164.

If the actuator is of the type SM.0.0.0.6

(failsafe and BACnet), check the battery

capacity (0-100%) in AV.140.
