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.

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.

NOTE! Additional measures regarding lightning protection might be
needed according to IEC 61400-24. See also chapter 2.3 Lightning
protection.
NOTE! Make sure that high voltage cabling and equipment will not
interfere ice detector system or cabling of ice detector.
NOTE! Do not coil cables because inductive coupling can cause
harmful interferences.
Instructions for proper use of ice sensor cable connectors are shown in
picture below. A narrow gap around 1 mm will remain, when the
connector is perfectly connected. This applies for both cables, signal
cable and heating supply cable.
More information is available in document D80359_E “Instructions for
proper use of LID/ISD ice sensor cable connectors”.
3.3 Relay outputs
LID-3300IP has two relays with potential free relay outputs. Both relays
have NC (normally closed), CC (common contact) and NO (normally
open) connections available at the connectors.
Ice alarm relay is de-energized during normal operation. Ice alarm relay
is energized when ice is detected.
Fault relay is energized during normal operation. Fault relay is de-
energized when fault is detected.
The safety function of the ice detector is validated through relay outputs.
See the table below:

3.3.1 Three-wire relay connection
If there is adequate amount of I/O in the automation, it is recommended
to use the three-wire connection for LID-3300IP Type 2 installation, as
shown in the figure below.
With this connection, the automation can detect if the cabling is properly
connected. In case there is an alarm state, the Ice alarm relay
connector pin 10 is Low and pin 8 is High. With no alarm, pin 10 is High
and pin 8 is Low (the situation in the figure below). If pins 8 and 10 are
Low or High simultaneously, the cable is faulty.
The same connection principle goes also for the Fault relay. However,
the pins are reversed. This is shown in figure below.
With this connection, the automation can detect if the cabling is properly
connected. In case there is a fault state, for the fault relay connector pin
5 is Low and pin 7 is High. With no fault, pin 5 is High and pin 7 is Low
(the situation in the figure below). If pins 5 and 7 are Low or High
simultaneously, the cable is faulty.

3.3.2 Two-wire relay connection
Two-wire connection is recommended only for old installations where
LID-3300IP Type 2 is used to replace a LID-3300IP. The connection
can be made:
a) See the figure below. Pin 9 (ice alarm relay) is used for the relay com-
mon contact, and pin 8 is connected to the automation system. The fig-
ure represents normal operating status, where no ice has been de-
tected. When ice is detected relay state changes to NO.
b) In case the automation can be reprogrammed, it is recommended to
use pin 9 (CC) for the common contact and pin 10 (NC) is connected to
the automation system. Thus, ice detection is activated if the control
unit or cable is faulty.
In two-wire mode, fault relay should always be connected from pins 5
and 6. Pin 5 is the input to automation, and pin 6 is the output from
automation. When connected this way, fault signal is activated e.g.
when cable is removed. See the figure below. The figure represents
normal operating status, where there are no faults active. If a fault
occurs, relay state changes to NC.

3.4 Analog outputs
Ice level can be read from the analog output, but this configuration is
not validated as Safety function. See connections from chapter 3 or
Appendix D.
3.5 Serial interfaces: RS-232 maintenance and optical fiber interface
LID is equipped by default with an RS-232 serial communication
interface for configuration and maintenance connection.
Also, an optical fiber serial interface is available as an option for
configuration and connection to SCADA systems. This requires an
additional RS2O Converter module to be installed inside LID (item 5 in
the picture in chapter 3).

5 LID-3300IP TYPE 2 ICE DETECTOR IN OPERATION
This chapter explains the basic operation of LID-3300IP Type 2 ice
detection system. Serial and Web user interfaces are explained in
different chapters.
5.1 Operating modes
LID-3300IP Type 2 ice detection system operates in different modes
which are explained below.
START MODE
When the Ice detection system is started, Fault relays are ON, until the
control unit receives reasonable data from the sensor. If the system is
working ok and the data is correct, Fault relays will be deactivated after
measurement data is correct.
SENSING MODE
LID continuously measures the signal level of the ice sensor. The
maximum signal amplitude value can be defined by the user by
parameter 2. By default, the signal value varies between 0 and 100.
Ice signal value is visible in serial and web user interfaces, and
available as continuous current message in the analog output.
In sensing mode, LID is asking the Ice sensor for measurement data.
Ice sensor is replying to this message by sending the measurement
data for ice, internal temperature and external temperature.
ICE DETECTED MODE
When ice signal goes below a defined alarm level (set by parameter 0),
LID goes to Ice detected –mode and gives an ice alarm. The delay of
an ice alarm can be set by parameter 3.
Ice alarm is visible in the Ice alarm LED of the front panel as well as
serial and web interfaces. Ice relay energizes and closes contacts 8 and
9.
Ice alarm and ice detected mode are active during the heating and
cooling phases that follow an ice alarm.
Parameter 22 can be used to set a delay for ice alarm deactivation. It
will keep the ice alarm active after the heating and cooling phase for the
duration of the time delay. This is to prevent repetitive alarms during a
long icing event.
HEATING PHASE
Right after the ice alarm is detected, ice sensor starts to heat itself to
get rid of the accumulated ice. It is also possible to disable heating by
parameter 12. The whole heating process can be controlled with
parameters 12 –18, 23 and 24. Default heating parameters shoud be
useful enough for most weather conditions.
Automatic heating is used to remove soft ice which has slowly
accumulated over the ice sensor in light icing conditions. It does not
generate an ice alarm. Automatic heating is controlled with parameters
23 and 24.
COOLING PHASE
When ice sensor is heated to the maximum heating temperature, LID
moves to cooling phase. Ice signal value is measured all the time and
it should be close to the maximum after the heating phase.
