Aqua-scope Kfrlwe01 Operating manual

Motor Servo for

Angled Seat Valves

SKU: KFRLWE01

Version: 1.0.0

Product Description

The Angle Seat Valve Servo is a motor for retrofitting existing and installed gate or angled seat gate

valves, popular in several European countries, into intelligent water control devices. It can be installed

and removed without any special tools and without interrupting water supply or cutting even into the

pipe. The device supports LoRaWAN industry standard for easy integration into existing networks, and it

can be controlled directly from an Aqua-Scope Monitor using LoRaP2P. One local button allows manual

operation. The motor is powered by an external 12V power supply.

Various adapter rings and an ingenious connection system allow the motor to be used on all modern

angled seat valves from DN15 to DN32. The unit can operate in harsh environments, even submerged,

and can be wired directly to an additional local water sensor pad.

Mounting

The motorized actuator can be used with all commercially available angle seat valves. However, due to

the variety of mechanics, certain adaptations must be made. For installation, leave the valve open or

rotate it to the open position. Plumbers recommend that the valve is fully opened first and then lightly

closed by turning it clockwise approximately 2 turns.

1. Remove the center screw from the hand wheel. Some manufacturers do not use the typical green

handwheel. However, the metal stem is always hidden under the plastic. Keep the screw for future

use.

2. Remove the handwheel.

3. Select one of the 4 adapters (A1...A4) for wrench size M17, M22, M27, or M30 that fits snugly on

the bottom of the valve bonnet (hexagonal or rectangular shape). If none of the supplied adapters

fit the valve, please take a picture, and send it to [email protected]. This helps us to

develop and manufacture adapters for valves we don't know yet. In the meantime, there is a

solution to the problem. See section 'Make an adapter if no adapter fits' below for instructions.

4. Select the correct ball bearing seat (W1 ... W3) and place it on the stem. If your stem is larger than

the 8x8 mm required by the largest bearing seat, the KFR cannot be used on your valve. If your

stem is even smaller than the smallest ball bearing seat of 6x6 mm, you can solve the problem in

the same way as for the adapter. See instructions below.

5. Tighten the ball bearing seat with the screw from step 1.

6. Depending on the size of the valve bonnet and stem, you may need additional distance rings (D1,

D2) on top of the adapter ring. If the inner coupling (K) cannot be pushed all the way into the main

body (G) without sitting on the valve body, or if the main body cannot be connected to the adapter

ring already installed, a distance ring (D1 or D2) must be placed between the adapter ring (Ax)

and the main body (G). This is usually the case with rising stem valves. The spacers are 12 or 24

mm, and they can be combined. Use the spare handwheel to open and close the valve for

verification.

7. Place the housing on top of the adapter or distance ring.

8. Place the inner coupling in the housing. It must pass over the ball bearings in both the open and

closed positions. The housing is clear to check this. If it does not fit, use other distance rings in

step 6. Please use the spare handwheel to open and close the valve to check.

9. The bracket is required to hold the entire assembly in place if the valve is not installed in an

upright position. It is recommended that the bracket be used in any case. Tighten around the pipe

using the two zip ties provided. You can remove the zip ties at any time.

10. Finally, place the motor on top of the housing. You may need to turn the inner coupling a little if

the motor does not fit right away.

Make an adapter if no adapter fits

The product is supplied with a portion of epoxy. This is a two-part mixture. Mix the two components by

kneading until the mass has a similar color. Select an adapter ring that just fits over the base structure

of the valve bonnet and fill the gaps with the prepared epoxy. Allow the epoxy to cure. Note that the

epoxy will adhere to the metal body. If you do not want the epoxy to stick, coat the metal body with

some oil to allow easy removal of the epoxy filled adapter.

In the same way, you can put epoxy in one of the bearing seats if your stem is smaller than the is

smaller than the 6x6mm of the smallest seat. Make sure the stem is positioned right in the centre of the

ball bearing seat.

Valves from Wilhelm Ewe GmbH & Co. KG

Users and Installation Manual: Motor Servo for Angled Seat Valves (KFRLWE01)

This company's valves have a very special design. You must insert the

split ring (E1+E2) into the 24 mm distance ring (D1) instead of using one

of the adapters A1 ... A4. No further distance ring is needed but a small

ring DE must be placed below the ball bearing seat to hold down the large

fat chamber.

External Flood Sensor

The unit allows an optional wired flood sensor to be attached. There is a

connector on the power cord next to the motor. Remove the blue

protective pad and plug in the sensor. Please use some force to push the connector to ensure a

waterproof connection. If the sensor head detects water, a flood alarm will sound, the valve will close,

and the alarm will be indicated by a buzzer and LEDs. 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 with a wireless

LORA command. In both cases, an Alarm Clear report is sent uplink to the LORA network.

Manually Operating the motor

You can open or close the valve by briefly pressing the button. If you press the button while the motor is

running, the motor stops moving and will reverse direction with next push.

The unit must be calibrated to recognize the end positions of the valve. Once these end positions are

known, the motor will stop softly at that position and not "slam into the wall" to protect the mechanics

and ensure long life and reliable operation. After power up, the unit will make some short movements to

determine if the last position was open or close. The first open or close operation is used to perform

calibration for both end points. No special user interaction is required for calibration.

Connect to LORA network

Please register the device with its three keys with your LoRaWAN server before you use it. before using

it. The device EUI is printed on the device. Enter this key and your registered email address to

https://aqua-scope.com/lora to obtain the missing keys. The email address is the account email from

Aqua-Scope Shop purchases or the data is provided by your point of sale. If there is no LoRaWAN

network or the LORA keys are not registered in the key, the LoRaWAN joining process will fail. LoRaWAN

connection will fail after about 25 seconds and the device will automatically switch to LoRaP2P mode for

connection to the Aqua-Scope Monitor. Please note that the device always tries to join a LoRaWAN

network after power on.

0x00 Valve Close

0x64 Valve Open

LoRaWAN Alarm Types

The following alarmtypes are supported.

0x0001 (Bit 00): All Alarms

0x0002 (Bit 01): Flood Sensor Tripped, VAL is 0x01 or 0x00.

0x0004 (Bit 02): Temperature out of limits, VAL is actual temperature. For encoding of

temperature please refer to section 'LoRaWAN Sensor Types'.

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.

Parameter 1 - Status interval: The device reports regularly to the LORA network. This

parameter defines the time interval for these reports in minutes. The default is 0x015 = 15

minutes. The value range is 0x0005 - 0x10E0

Parameter 2 - Message type: This parameter defines whether confirmed or unconfirmed

messages are sent over LoRaWAN. The default is 0x01 = confirmed message. The value 0x00 sets

to unconfirmed message.

Parameter 3 - Scale value for temperature report: This parameter defines whether a

temperature value should be in Celsius (0x00) or Fahrenheit (0x01). The default setting is Celsius.

Parameter 4 - Repeat alarm report: 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. Here the default setting is 0x01. This means the

default parameter is 0x0301.

Parameter 5 - Regular valve training: A valve should be moved regularly to maintain its

smooth operation. The device can perform this training independently from control by a LoRa

Users and Installation Manual: Motor Servo for Angled Seat Valves (KFRLWE01)

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 - Local display: 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 - Threshold value for temperature report: 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). The default value is 0x000a.

Parameter 8 - Motor Power: This parameter allows limiting the motors torque. Max torque is

0x64 = 100 percent. Valid values are 0x50 .. 0x64. The default value is 0x0050.

Parameter 9 - Valve Turns: Set the total turns of the valve. This value is set by calibration but

can be changed manually if desired.

Parameter 10 - Automatically close valve when external flood sensor trips: On default

(value=0x01) the valves will close when the sensor trips but setting the value to 0 will suppress

this function. The alarm is still reported and shown on the device.

Parameter 11 - Buzzer notify when join the server: When the device joins to a LoRaWAN

server, the buzzer will sound (value=1). This function can be suppressed with value = 0.
