LID-3300IP Type 2 Ice Detector DOC001181-EN-3

Installation and Operating Instructions

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.

Installation and Operating Instructions

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.

LID-3300IP Type 2 Ice Detector DOC001181-EN-3

Installation and Operating Instructions

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”)

Installation and Operating Instructions

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.

Installation and Operating Instructions

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.
