1 PRODUCT OVERVIEW
LID-3300IP Type 2 is an ice detector for wind turbines and
meteorological stations. LID-3300IP Type 2 ice detector system
consists of LID-3300IP Type 2 control unit (later referred to also as LID)
and LID/ISD Type 2 ice sensor (later referred to also as ice sensor).
LID-3300IP Ice Detector system, Type 2, is the latest version of the
product, which fullfills the requirements of PLd according to ISO 13849-
1. The safety function is validated through relay outputs.
LID monitors the icing weather conditions on-line and reports icing
events through various interfaces. Ice alarm and other measurement
information are available via 2 relay outputs, 2 analog outputs, front
panel or optical fiber interface and TCP/IP Web user interface or
Modbus.
Ice detection of the ice sensor is based on an ultrasonic principle.
Ultrasonic signal attenuates when ice is accumulated on the sensor
wire.
By default, LID starts to heat itself after an ice detection to get rid of the
accumulated ice.
Alarm levels and ice sensor heating, among other functions, can be
controlled by user-configurable parameters. Certain factory parameters
have been defined by the manufacturer, which allow start-up and
operation without any additional configuration.

2 INSTALLATION
Mounting, installation, commissioning, operation, maintenance and
disassembly of the system may only be carried out by trained, qualified
personnel. The instruction manual must be read and understood.
2.1 Installation and interfaces of LID-3300IP Type 2 Control Unit
The enclosure of LID is wall-mounted. Mounting holes are located in
the base plate of the enclosure, beneath the mounting holes of the front
cover.
2.2 Installation of LID/ISD Type 2 ice sensor
The ice sensor is designed for mounting on a weather mast. The
preferred place for installation in a wind turbine is on top of the nacelle.
The correct installation position is marked with an upwards-pointing
arrow label.
The ice sensor should be mounted against the wind so that there is free
airflow in front of the ice sensor. See the below figure for the preferred
installation direction. Free air distance must be minimum 500 mm.
Avoid installations where there is a possibility that the ice which
accumulates to surrounding structures might reach the ice sensor.
A standard delivery includes a mounting kit for installing the ice sensor
on the weather mast. See the figure below. Other mounting options are
also available on request.

Flammable materials or materials that may melt are not allowed to
locate close to the ice sensor.
The ice sensor body includes a 350W heating resistor. A temperature
sensor T1 (ice sensor temperature) is located in the centre part of the
ice sensor and temperature sensor T2 (ambient temperature) inside the
connector of the ice sensor cable. A safety thermostat is also mounted
inside the body of the ice sensor to break the heating circuit if the ice
sensor temperature rises above +65 °C.
NOTE! Ice sensor shall be placed in a way that it is not influenced by
the warm air from the exhaust of the turbine cooling system.
NOTE! Ice sensor shall be placed in a way that it is within LPZ0B (see
next chapter “Lightning protection”)

2.3 Lightning protection
Lightning protection for LID-3300IP control unit and LID/ISD ice sensor
shall be done according to standard IEC 61400-24 “Wind turbines –
Part 4: Lightning protection” when installed into a wind turbine.
General principles for protecting ice detector system against
overvoltage in case of lightning strike is presented in the above picture.
Components in the picture are:
1. LID-3300IP Type 2 control unit
2. Surge protection device
3. Automation cabinet
4. Metal tubes
5. LID/ISD Type 2 ice sensor
6. Holder for ice sensor
7. Air termination rod

3.1 Power supply
The device does not have a mains switch. During maintenance and
service operations it has to be possible to switch off the main supply.
Only an authorized electrician is allowed to install power supply cable
to LID-3300IP control unit.
The installation of power supply can be done by two alternative ways:
- Permanent wiring: using a two pole mains switch (250 Vac,
minimum 5 A), which isolates both lines (L1, N). Switch must be
installed in the main power supply lines in the vicinity of control unit.
Switch must be in accordance with IEC 60947-1. Copper wires 1.5
- 2.5 mm2(AWG 16 - 13) can be connected to the power supply
terminal of the control unit.
- Plug connection: using supply cable with plug that can be
disconnected from socket outlet when necessary. Remember to
tighten the strain relief of the cable gland.
Control unit must always be connected to protective earth (PE).
3.2 Connections between ice sensor and control unit
The cables connecting the ice sensor and LID are included in the
delivery. The standard length of the cables is 10 m.
Only an authorized electrician is allowed to install heating cable
between ice sensor and LID.
The connections between LID-3300IP Type 2 control unit and LID/ISD
Type 2 ice sensor are shown in the following figure. Optional
temperature sensor extension cable improves ambient temperature
accuracy. Included Heat shrink tube is recommended to be added
around the extension cable connectors for extra protection against
possible water leakage.
