Motor Servo for Angled Seat Valves

SKU: KFRLWE01
Version: 1.1 (May25)

1. Product Description

The motor drive for angle seat valves (KFR valves) enables the retrofitting of existing and already installed shut-off valves into remotely controllable smart devices, without interrupting the water supply or cutting into the water pipe.

The motor can be controlled in three different ways:

  1. The device can be directly paired with Aqua-Scope main sensors (internet-connected sensors) of the AQM, AQS, or AQX series using the Aqua-Scope app and is then controlled by these sensors. No LoRaWAN network is required. Instructions can be found in the section 'Pairing with Aqua-Scope Main Sensors'.
  2. The motor can be directly paired with Aqua-Scope control sensors (not internet-connected) of the FLO, DRY, or CLP series without requiring any additional wireless connection to the internet or a LoRaWAN network. Instructions can be found in the section 'Pairing with Aqua-Scope Control Sensors'.
  3. The device supports the LoRaWAN wireless protocol and can be integrated into an existing LoRaWAN network as a Class C device. This requires LoRaWAN network coverage and that the device keys be registered with the LoRaWAN provider’s JOIN server. If no LoRaWAN connection is available, the device will automatically accept control commands from Aqua-Scope sensors after about 20 seconds. Details can be found in the section 'Communication with a LoRaWAN Network'.

The three control methods are mutually exclusive. For example, if the motor is connected to LoRaWAN, it can no longer be directly controlled by an Aqua-Scope sensor. To enable that again, the motor must be reset to factory settings. Information on this can be found in the "Button Operation" section. Other radio systems (Wi-Fi, Shelly, etc.) can be integrated using additional adapters that are screwed between the connectors in the power supply. Communication between these adapters and the motor itself occurs via the power cable.

The motor is powered by a 12V power supply and is fully water- and dirt-resistant up to the power supply unit. An optional battery pack is available for off-grid operation.

Various adapter rings and a sophisticated connection system allow the motor to be used with all modern angle seat valves from DN15 to DN32. Thanks to an additional water sensor that can be plugged directly into the device, the motor can also be used for leakage protection without any wireless connection at all.

3. Installation of the motor


3.1. Mounting the motor on the valve

The motor drive can be used with all commercially available angle seat valves. However, due to the variety of mechanisms, certain adjustments must be made. When installing, the valve should be normally open (installers recommend opening the valve fully and then closing it slightly with approx. 2 clockwise turns).

  1. First, loosen the screw in the center of the handwheel using a screwdriver. Some manufacturers do not use the typical green handwheel. The spindle may be hidden under plastic, but will always have a screw on top and a square end. Keep the screw for later use.
  2. Now remove the handwheel.
  3. Select one of the 4 adapters (A1...A4) for wrench sizes M17, M22, M27, or M30 that fits well onto the bottom of the valve top (hexagonal or rectangular shape). If none of the supplied adapters fits the valve, refer to the “Custom Adapter” section for further guidance.
  4. Select the correct ball bearing seat (W1 ... W3) and place it on the spindle. If the spindle is larger than 8x8 mm, which is required for the largest ball bearing seat, this product cannot be used for this valve. If the spindle is smaller than the smallest ball bearing seat of 6x6 mm, the issue can be resolved similarly to the adapter case. See the instructions in the “Custom Adapter” section.
  5. Now fix the ball bearing seat with the screw from step 1.
  6. Depending on the size of the valve top and spindle, additional spacer rings (D1, D2) may be required on the adapter ring. If the inner coupler (K) cannot be pushed all the way into the main housing (G) without resting on the valve housing, or if the main housing does not reach the already installed adapter ring, a spacer ring (D1 or D2) must be placed between the adapter ring (Ax) and the main housing (G). This is usually the case with rising spindle valves. The spacer rings are 12 or 24 mm in size and can also be combined into a 26 mm ring. The spare handwheel can be used to test the opening and closing of the valve.
  7. Now place the housing (G) onto the adapter or spacer ring.
  8. Insert the inner coupler into the housing. It must reach over the ball bearings in both the open and closed positions. The housing is transparent for this purpose.
  9. The retainer (N) is needed to hold the entire assembly in position if the valve is not installed upright. It is recommended to always use the bracket. The complete device is attached to the pipe using the two included cable ties. The cable ties can be removed at any time. To slide the retainer over the housing, the two tabs on the housing must be slightly pressed together. There are two small notches on the inner ring of the retainer for this purpose.
  10. Finally, place the motor head onto the housing. Sometimes the inner coupler must be slightly rotated so that the gear structure of the motor meshes with the inner coupler.


3.2. Valves from Wilhelm Ewe GmbH and Co. KG

The valves from this company have a unique design. You must insert the split ring (E1+E2) into the 24 mm spacer ring (D1) instead of using one of the adapters A1 ... A4. A small additional spacer ring (DE) is placed directly under the ball bearing seat to fix the valve's grease chamber.


3.3. Custom Adapter

If no suitable adapter is available for the valve seat, a custom one must be made. To do this, select an adapter that fits over the valve seat and fill the gap with a two-component resin. This resin is included with the motor. Cut off a piece of the compound with a utility knife and knead it until a uniform color is achieved. Then fill the gaps between the adapter ring and the valve base. After the resin has hardened, the now custom-fit adapter ring can be used.

Note: The resin will adhere firmly to the valve. If this is not desired, lightly oil the valve beforehand. Then the hardened adapter ring can be removed more easily.

Similarly, a ball bearing seat can be adapted for a valve shaft with a square smaller than 6x6 mm. Ensure that the spindle is precisely centered in the ball bearing seat.


3.4. Setting the End Positions of the Motor Drive

Once the motor is mounted and powered, it must determine the correct end positions for the ‘OPEN’ and ‘CLOSE’ positions:

  1. Manually turn the valve to the ‘OPEN’ position before the motor is initially installed. According to installer recommendations, the optimal ‘OPEN’ position is about 2 turns towards ‘CLOSE’ after reaching the stop in the ‘OPEN’ direction (counterclockwise).
  2. Power the motor.
  3. Press the button briefly once. The motor will now move briefly in both directions and determine whether it is in the ‘OPEN’ or, contrary to the recommendation in step 1, in the ‘CLOSE’ position. This information is indicated by the color of the LED on the device.
  4. If the motor was initially in the ‘OPEN’ position, the first ‘CLOSE’ command (either via short button press or external control) will move it fully to the ‘CLOSE’ position and then slightly reverse. This function is intended to relieve the valve's rubber seal. If the seal has become brittle from long-term closing or aging, this may lead to valve leakage in the ‘CLOSE’ position. Therefore, this slight reverse function can be disabled.

Once the end positions are recognized, the motor will no longer forcefully drive against the valve's endpoints, but will instead count the required motor turns and approach the endpoints gently.


4. External Cable Water Sensor

An optional wired flood sensor can be connected to the device. There is a connector on the power cable near the motor. Remove the blue rubber plug and insert the sensor. Please press the plug in firmly to ensure a waterproof connection.

When the sensor head detects water, an acoustic signal sounds, the valve closes, and the alarm is indicated by a flashing red LED. In addition, an alarm message is sent via LoRa radio. Once the sensor head is free of water, you can clear the alarm by pressing the button for 2 seconds. It is also possible to clear the alarm via radio.


5. Operation on the Device Itself

The device has a single button with a built-in three-color LED. To operate the valve, you can click the button or hold it down for a few seconds. The motor helps count the seconds by beeping once per second. The device is designed for outdoor use and must prevent malfunctions caused by water droplets on the button. Therefore, please press the button firmly (not too gently), even for a short click, so that the touchless button recognizes your finger.


5.1. Button Operation

The valve can be opened or closed via the button on the motor head (G) by briefly pressing it. In addition, the following special commands are available:


5.2. LED Signals

The device has a two-color LED with the following meanings:


6. Motor Control via Radio


6.1. Pairing with Aqua-Scope Main Sensors

If a motor is operated with an internet-enabled Aqua-Scope sensor (AQS, AQM, AQX), the sensor must first be connected to the internet. The Aqua-Scope app then allows you to add the motor as a sub-device to the main sensor in the "Configuration" section. The motor is then always controlled via this sensor. In case of an alarm, a control signal is sent directly to the motor without using the internet connection.


6.2. Pairing with Aqua-Scope Control Sensors

The device can also be controlled directly by non-internet-enabled Aqua-Scope sensors (FLO, DRY, CLP). These must be paired with the motor. The sensors are put into pairing mode for this purpose. Information on pairing mode can be found in the manuals of the respective products. On the motor, press the button twice quickly. The sensor and motor are now paired, and the sensor can shut off the water by controlling the motor in the event of an alarm.


6.3. Communication with a LoRaWAN Network

Please register the device with its three keys on your LoRaWAN server before putting it into operation. The device EUI is printed on the device. Enter this key and your registered email address at https://aqua-scope.com/lora to receive the remaining two keys. The email address is the account email from the Aqua-Scope shop, or the data will be provided by your vendor.

If there is no LoRaWAN network or the LoRa keys are not registered in the LoRa network, the LoRaWAN connection process will fail after about 25 seconds, and the device will automatically switch to LoRaP2P mode for direct control by Aqua-Scope sensors. Please note that the device will always attempt to connect to the LoRaWAN network after power is turned on.


7. Technical Information on LoRaWAN Communication


7.1. LoRaWAN Payload Commands (Payload Format)

LoRaWAN commands can be daisy chained into the payload up to the defined maximum payload size of 51 bytes. This mean that for all commands sent to defined number of bytes in the payload is required to avoid misinterpretation of command and/or command values in the receiver side. All uplink and downlink commands use FPort=10.


7.2. LoRaWAN Sensor Types

The following sensor types are supported by the Aqua-Scope Monitor.


7.3. LoRaWAN Valve Positions for Command 0x07


7.4. LoRaWAN Alarm Types

The following alarmtypes are supported.


7.5. LoRaWAN Configuration Parameters

All Configuration Parameters are 2 Byte values that can be set and read out using LoRaWAN 'Configuration Get' and 'Configuration Set' commands. Here is an overview of the configuration parameters currently used:

Parameter 1 (0x01): Heartbeat Interval (Default: 0x000f = dec 15)

This parameter defines how often (in minutes) a status report is sent out.

Parameter 2 (0x02): Message type (Default: 0x0001 = dec 1)

This parameter defines whether confirmed or unconfirmed messages are sent over LoRaWAN. 0x01 = confirmed message, value 0x00 unconfirmed message.

Parameter 3 (0x03): Scale value for temperature report (Default: 0x0000 = dec 0)

This parameter defines whether a temperature value should be in Celsius (0x00) or Fahrenheit (0x01).

Parameter 4 (0x04): Repeat alarm report (Default: 0x0001 = dec 1)

This parameter defines how an alarm report is sent to the LoRa network. The parameter combines two different values: The more significant byte describes how often an alarm packet is retransmitted. The default setting here is 0x03 = 3 times. A value between 0x00 (no repetition) and 0xff (unlimited repetition) can be selected. The least significant byte defines the repeat interval in minutes.

Parameter 5 (0x05): Regular valve training (Default: 0x0107 = dec 263)

A valve should be moved regularly to maintain its smooth operation. The device can perform this training independently from control by a LoRa network. The parameter combines two different values: The higher-order byte describes whether (1) or not (0) valve training should take place. The low-order byte defines the interval of the training in days. Values between 1 and 30 days are possible. The default value is 0x0107, i.e. training takes place every 7 days.

Parameter 6 (0x06): Local display (Default: 0x0101 = dec 257)

With this parameter the buzzer and the LEDs can be activated (0x01) or deactivated (0x00) directly at the device. The lower byte defines the behavior of the buzzer, the higher byte the behavior of the LED. The default value is 0x0101, i.e. both buzzer and LED are active (for example during motor movement).

Parameter 7 (0x07): Threshold value for temperature report (Default: 0x000a = dec 10)

This parameter defines at which temperature change an additional temperature report is sent in addition to the regular temperature report. The value is given in 0.1 degrees Celsius and must be greater than 0x000a (= 1 degree).

Parameter 8 (0x08): Motor Power (Default: 0x0050 = dec 80)

This parameter allows limiting the motors torque. Max torque is 0x64 = 100 percent. Valid values are 0x50 .. 0x64.

Parameter 9 (0x09): Valve Turns (Default: 0x000a = dec 10)

Set the total turns of the valve. This value is set by calibration but can be changed manually if desired.

Parameter 12 (0x0c): Low Power Min Awake Time (Default: 0x0000 = dec 0)

Used in Battery Mode. Don't change

Parameter 13 (0x0d): Low Power Duration (Default: 0x0003 = dec 3)

Used in Battery Mode. Don't change

Parameter 14 (0x0e): Wakeup Report Trigger (Default: 0x000a = dec 10)

Used in Battery Mode. Don't change

Parameter 15 (0x0f): Second Key Enable (Default: 0x0001 = dec 1)

This parameter defines if the direct pairing to sensors without involvement of an App is enabled. (1 = enabled, 0 = disabled)

Parameter 16 (0x10): AutomaticallyDetect Position on Power-On (Default: 0x0000 = dec 0)

0 = do it on first button resp. first wireless command, 1 = do it always on power on

Parameter 17 (0x11): Gasket Relaxing in Close-Position (Default: 0x000a = dec 10)
