LiquiCount LC1
Safety information
Important requirements for safe installation and use with anti-ice and de-ice fluid systems on air-side ground support vehicles.
Intended use
The LiquiCount LC1 is designed to monitor pulse-based measurement data from compatible sensors in anti-ice and de-ice fluid systems used by air-side ground support vehicles.
The device is not intended for:
- Legal metrology applications
- Billing or trade measurement
- Safety-critical control systems
- Protective interlocking systems
- Use in explosive (ATEX) atmospheres
- Medical applications
Use of the product outside its intended purpose is the responsibility of the installer or end user.
Electrical safety
The LC1 operates exclusively from a 12–28 V DC SELV (Safety Extra Low Voltage) supply.
The device must only be powered from a properly regulated SELV source.
- Do not connect to mains voltage.
- Do not connect to DC supplies exceeding 28 V.
- Do not connect to AC supplies.
Incorrect supply voltage may cause equipment damage and may invalidate warranty. All signal inputs and outputs are SELV-level circuits only.
Installation requirements
When the LC1 is fitted to an air-side ground support vehicle, its location, enclosure and wiring must be suitable for the vehicle, fluid system and operating environment.
- Installation must be performed by competent personnel.
- The device is intended for fixed installation within a panel or enclosure.
- Ensure correct sensor supply voltage selection prior to connection.
- All wiring must comply with local electrical regulations.
- Do not over-tighten mounting screws.
- Disconnect power before wiring or servicing.
Mechanical safety
The enclosure is designed for normal handling during installation and operation on air-side ground support vehicles.
- Do not subject the device to excessive mechanical shock.
- Do not strike or impact the enclosure.
- Do not use the enclosure as a structural support.
Mechanical robustness has been evaluated in accordance with EN 61010-1 requirements for accessible surfaces.
EMC considerations
This equipment has been designed and tested in accordance with EN 61326-1 (EMC requirements for measurement, control and laboratory equipment).
To maintain EMC performance:
- Route sensor wiring separately from high-power conductors.
- Follow the installation instructions.
