Datasheets, installation manuals, wiring information and answers to the questions engineers ask most.
Configure, operate and diagnose SMART actuators over Bluetooth from Android 8.1+.
Google PlayYes — an Android device running Android 8.1 or later. An iOS version is in development.
Search for “RIFT Actuators” to find and install the app.
Open the RIFT Actuators app and tap “Register” on the sign-in screen, or use the registration form on RIFTdev. Accounts are validated at the factory — contact us with your registered email to arrange this.
The pairing code is 1234.
Long-press the app icon, open App info → Permissions and allow “Nearby devices”.
Some Android versions require pairing first: go to Settings → Bluetooth, search for nearby devices and add the actuator with code 1234. Keep within about 5 metres.
Actuator serial numbers must be allocated to your distributor or customer account. Send us the serial numbers and we will authorise them.
Yes. We use a well-understood 18650-cell 4-cell pack with over-charge, temperature and low-voltage protection in the electronics and software. We recommend battery replacement every 3 years, although the manufacturer suggests 5–8 years without significant degradation.
Yes. The analogue signal only sets position; external power supplies the battery charging circuit, Bluetooth module and anti-condensation heaters.
0–10 V, 4–20 mA and 0–20 mA. Settings such as sample rate can be configured at the factory for specific requirements.
Use the Wiggle feature: the actuator moves the valve a programmed amount at a programmed frequency. A genuine control command always overrides the Wiggle routine.
Yes. The incoming supply powers the charging circuit, Bluetooth and anti-condensation heaters only.
Disconnect the battery for travel, storage or periods of more than six months without power. A fully charged battery supports more than 200 cycles. If LED 1 flashes orange, allow the unit to charge — usually an hour restores normal operation; contact us if it persists.
The RXW (2–6 Nm) for small open/close valves, and the RAS SMART (10–30 Nm) in the SMART range.
Our engineers provide application design assistance, commissioning support and post-commissioning diagnostics.
From 1.5 Nm to 14,000 Nm — SMART, electric and pneumatic actuators, all designed and supported from Bournemouth.
Whether you are specifying cooling valves for a new data hall, automating a remote water asset or integrating actuation into your own product, our engineers can help you match torque, speed, failsafe and communications to the application.
