Valve Actuator Tree

How to setup your Actuator Tree.

 TECHNICAL DATA

Detailed technical data can be found on the Product Datasheet here.

SETUP

The valve actuator performs calibration after being learnt in to the system. The valve actuator should be installed on the valve before commissioning. Make sure the valve pin is secure and not rusty before fitting the actuator.

To commisioning, the actuator tree connect the 24V power (orange/orange-white) and the Tree (green/green-white).
Ensure the correct punch down tool is used to terminate cable.

There are also the following outputs for troubleshooting:

  • Online Status
  • No valve detected
  • Valve stuck

After the actuator has been learnt in it will start calibrating. This is where the valve actuator will learn the travel from 0% to 100% position. Many valves reach maximum flow rate at 50% of actuator value. You can adjust the correction value by setting “target value 2” to 50 in the properties of the analogue output of the actuator. This varies from valve to valve.

CONFIGURATION

The analogue output of the actuator can be linked directly to the output ‘Qh’ of the Intelligent room controller block.

LED STATUS

Icon Exclamation Mark LoxonePlease note the LED’s on the Actuator Tree cannot be disabled, these are intended for the use on manifolds. For control over in-room valves we suggest using the Actuator Air.

 

RED flashing quickly (approx 5Hz) no bus communication possible

Please check cabling
YELLOW flashing quickly
(approx 5Hz)		 Tree device was detected on the bus, but it is not learnt in the Miniserver
GREEN 3x short flashes Device learnt in, communication OK
RED flashing
(approx 1Hz)		 Online, Valve> 90% open Device Identifying itself (does not work with Batteries)
ORANGE flashing
(approx 1Hz)		 Online, valve between 10% -90%
GREEN flashing
(approx 1Hz)		 Online, Valve < 10% open
RED light There is the problem “valve stuck” or “not detected valve” before.

Please check the valve pin, this should move smoothly

 

DEVICE TEST

The actuator can be opened or closed completely for test purposes. To perform this test, right click on the actuator in the Periphery. Here, you can now carry out the device Start Device Test  (= fully open actuator),  Stop Device Test (= fully close actuator) and obtain the travel  details (Recalibrate Device).

DEVICE CALIBRATION

In order to ensure that the actuators know the exact movement of the valve they have been placed on they must run a calibration procedure. This is done automatically when you first learn the actuators in so we recommend you learn in and power up your actuators for the first time when they are mounted to the respective valve. If this is not done you will need to recalibrate the actuator manually the process for this is:

  • Open Loxone config and connect to your Miniserver and load out from it.
  • Ensure the Tree Extension or Actuators are not updating.
  • In the periphery right click on the actuator and select “Calibrate Device” this can take up to 20 seconds to happen and you will hear it begin to move on the calibration cycle.
  • Repeat this process for all actuators.
