FlowCon DN15-250 Energy FIT System Instruction Manual

Installation and Operation Instruction

The FlowCon SM are available in two different double union end connected models covering five different sizes and four different flanged models covering nine different sizes:

1. FlowCon SM.1 DN15-25 (1/2”-1”)
2. FlowCon SM.2 DN25-40 (1”-1½”)
3. FlowCon SM.3 DN50-80 (2”-3”)
4. FlowCon SM.4 DN80-100 (3”-4”)
5. FlowCon SM.5 DN125-150 (5”-6”)
6. FlowCon SM.6 DN200-250 (8”-10”)

O-rings are supplied with the valve body and are used to seal the connections. It is recommended to grease the O-rings with silicone grease.
Please make sure these are properly placed in the O-ring grooves on valve inlet and outlet, before installing the housing. Please note that FlowCon SM.6 (DN200-250 / 8”-10”) contains two O-ring grooves. Use the inner groove for DN200 / 8” flanges and outer groove for DN250 / 10” flanges.

The actuator types FlowCon SM.0.0.0.3, SM.0.0.0.4 and SM.0.0.0.6 are electrical programmable actuators. SM.0.0.0.6 is a BACnet actuator and has a supplementary instruction on BACnet connection and programming.

Fitting and Re-fitting the actuator

It is recommended to grease the O-ring on the spindle adaptor with silicone grease before placing the spindle adaptor on the valve spindle.
1 Then place the actuator on the spindle adaptor and place the three actuator “legs” into the three holes in the mounting bracket (figure 2 and 3).
Make sure that the snap ring is clicked onto the mounting bracket, so that the snap ring is locked at the top of the mounting bracket, but still able to rotate. 2 Then finger-turn the snap ring counter clockwise (upside view) approximately 1/6 of a turn until its stop points touch the actuator “legs” and the mounting is lock with a (small) click. Do not use additional tools.

In case the actuator will have to be removed, it is recommended to electrically open the valve for easier removal. Hereafter reverse the procedure and  3 turn the snap ring clockwise until the actuator is loosened and  4 lift the actuator up.
Again, no need for additional tools.

Do not remove cover from actuator.
Opening cover will void warranty.

Orientation

Upside-down installation is allowed along with the standard horizontal and vertical installation (figure 5).

Wiring

If feedback signal is not required, leave green wire detached.

Remember to remove the protection film from the actuator display to avoid condensation.

Start-Up Sequence

When power is turned on, the actuator will automatically calibrate to determine closing point of the valve. Calibration can take up to 10 minutes depending on the valve’s position at start-up.
During calibration actuator display will show “CAL”. Hereafter it will procced to normal operation mode (according to control signal).

If no control signal is detected, flush is started if enabled in the programming menu (enabled by default), opening the valve to 5/6 of fully open.
Actuator display will show “FLUSH” until control signal is detected.

At first start-up please enter programming menu to set actuator settings.

Programming Menu

The programming menu is always accessible. To enter the programming menu, simultaneously press and for 6 seconds, until bottom line in display blinks.

To change a value, press or . For quick scroll through values hold down  or . Press to accept a value and go to next step and press to go to previous step.

For fast menu exit press and simultaneously for 6 seconds. The actuator will automatically return to normal operation mode if no action is detected on arrow keys for 1 minute.

All values selected in the programming menu are stored in non-volatile memory.

Note 1: The flow rate shown on the actuator display is a calculated value. Flow rates below 1.0 valve rotation is shown as indications, illustrated with an apostrophe in front of the flow rate. If display shows “NA” the valve model has not been chosen in programming menu step 2.

Alarm Menu

To enter the alarm menu, simultaneously press and for 6 seconds. The alarm menu is only accessible if an alarm is present (i.e. when the icon is displayed). Press to go to the next alarm display and press to go to previous.

For fast menu exit press and simultaneously for 6 seconds. The actuator will automatically return to normal operation mode if no action is detected on arrow keys for 1 minute.

If the actuator is still functioning (= warning code 02, 04, 05 with failsafe and 07 with failsafe), the icon will blink. If the actuator is NOT functioning (=error code 01, 03, 05, 06 with failsafe and 08), the icon is fully on. Error codes will be shown in the information part of the actuator display.

Password: 3569266.
Code| Icon| Description| Details
---|---|---|---
01|

FULL ON

| Valve/actuator is overtorqued.| Operation is stopped. Actuator will retry operation every 4 minutes. If over torque condition disappear, error will convert to error code 02
02|

BLINKING

| Actuator has reached its torque limit in the past.| Actuator is functioning.
To reset the alarm simultaneously press and
 for 6 seconds.
03|

FULL ON

| Critical – over temperature| Critical: Temperature in actuator is at least 70ºC, motor operation is stopped. If temperature is decreasing, operation will resume.
04|

BLINKING

| High temperature.| Actuator is still functioning. Temperature in actuator is at least 50ºC as limited according to tech note. If temperature is decreasing, operation will resume.
05|

FULL ON

| No Failsafe: Power supply not in range.| Operation is stopped. Alarm will automatically reset when voltage is back in range.

BLINKING

| With Failsafe: Power supply not detected / not in range.| Failsafe is activated. Alarm will automatically reset when voltage is back in range.
06|

FULL ON

| Control signal not detected.| Operation is stopped. Alarm will automatically reset when control signal is back in range.
07|

BLINKING

| Battery error.| Battery is not properly connected. Alarm will reset when battery is properly connected.
Only valid for failsafe actuators.
08|

FULL ON

| BACnet fallback mode| BACnet control value has not been updated and BACnet fallback timeout has been reached. Alarm will reset when BACnet control signal is refreshed.
Only valid for BACnet actuators.

Auto-stroke sequence

In case the valve does not operate as expected, start the auto-stroke sequence to re-calibrate the closing point making sure that the actuator is able to open the valve fully. Press and simultaneously for 6 seconds to start auto- stroke.
An auto-stroke sequence cannot be cancelled. During auto-stroke actuator display will show “AUTO STROKE CYCLES”. Hereafter it will proceed to normal operation mode (according to control signal). If the actuator is not able to open valve fully, error code 01 will be displayed.

Manual Override

Manual override is used to temporarily set the valve position regardless the settings and control signal for the actuator. Disconnect power to the actuator and remove the actuator from the valve. Turn the valve spindle clockwise to close valve and counter-clockwise to open. Re-mount the actuator and connect power. Be aware to protect that actuator from water while not on the valve.

When manually operating the vale (actuator disconnected) do not use more than 10 Nm torque. Use of higher torque will void warranty.

Failsafe Mode

In case of power failure, failsafe models will move actuator to the position chosen in programming menu step 13 and show warning code 05 in the actuator display. When voltage is back in range will be reset.
