GENERAL – INTENDED USE
GIGASENSE II is an Anti-Collision System designed for Overhead Travelling (EOT) cranes or
other machinery running on a common set of rails.
In the most common case, where two EOT-cranes on the same track both need to be
protected from collision, two units are needed. When the crane should be protected from
running into a wall or track end, one complete unit (antenna and relay box) in combination
with one unit consisting of only the antenna and power supply (no relay box is needed) is
required.
The antenna is mounted with the center axis in the direction of movement, always pointing
towards the opposite antenna. The relay box is mounted apart from the antenna, normally
nearby the crane control functions.
Each unit works according to the SFCW (Stepped Frequency Continuous Wave) radar
principle, sensing the relative speed and distance to the reflecting transponder in the
opposite antenna. By using a modulated “fingerprint” reflection in the opposite antenna, the
system is not disturbed by undesired echoes from surfaces on the crane and other metal
parts.
The antenna is powered by the relay box and data from the antenna is continuously
received, every 128ms. The relay box has three potential free relay contact outputs which
are controlled by Limit 1 and Limit 2 for braking and stopping the crane movement. One
output relay is used for internal fault monitoring. The relays are held active by the
electronics and any exceeded limit or alarm of the function will make them trigger. Settings
and readout of parameters are easily accessible via a display and push buttons in the relay
box.
The internal fault monitoring is performed continuously. If the opposite unit has been turned
off or has a power failure, the modulated reflection remains active. This is because each
antenna has a backup receiver (rechargeable supercapacitor) for the modulating fingerprint
reflection and will continue to work for about 6-12 hours (depending on the temperature).
When the backup receiver has unloaded in a unit, the opposite unit still senses a signal from
the beam or other metal parts of the crane, which triggers an alarm to stop the movement
of the crane. For correct detection of this function, it is necessary to have a surface of metal
with minimum 1 m² behind the antennas.
GIGASENSE II contains a Microwave transmitter. Although it has very low output power, this
system must conform to the local regulations set up by the Telecom Authority in the user
country. This equipment operates in the 9.9 - 10.6 GHz frequency bands. See appendix 1 for
detailed information.

etc.
SAFETY & ENVIRONMENT
• Protects property and production.
• Designed to work in the toughest conditions such as in steel works, harbors, mines
• Fail Safe operation thanks to supervision of function, both in antenna box and relay
box. The antenna unit is supervised by a watchdog. The relay box automatically puts
the system in failure mode (all three relays in alarm position) if data is not received
from the antenna box.
• The signal is very hard to disturb, the A- and B- units use different frequencies,
different polarization of the Microwaves and a "fingerprint" radar reflection. The
"fingerprint" radar reflection function has a backup super capacitor in case of short
power failures.
• The Anti-Collision System is not disturbed by rain, dust/metal particles, fog, or
sunlight.
FUNCTION – two moving cranes
By using SFCW (Stepped Frequency Continuous Wave) radar technique, the distance and
relative speed are calculated.
The modulated (fingerprint) reflection to the opposite unit is made by a diode in the
microwave head. The diode oscillate with 16 kHz. As long as the diode oscillates, the
opposite unit recognize the unit.
NOTICE! The maximum range is given as 40 m in the illustrations below. The range varies for
different frequencies from 20 m to 50 m due to limited allowable output power (EIRP), see
appendix 1.
The range is the distance between the Unit A and the Unit B, when the units having contact
(signal) with each other. The limit 1 and limit 2 can be set in this range.
If the distance between the Unit A and Unit B is longer than the range, the system “waits“
for the signal from the opposite unit, therefore the distance between the Unit A and Unit B
can be much longer than the range.

Principle of the unmodulated signal reflection in the Gigasense II system:
Figure 3A. Unit A (or Unit B) transmits an unmodulated Microwave signal towards the
unidentified object.
Figure 3B. The Microwave signal is reflected unmodulated by the unidentified object and
received in the Unit A (or Unit B) where it triggers an alarm.
Unmodulated signal reflection can occur when an identified object is suddenly detected in
front of the antenna, if one unit (A or B) malfunctions or if unit (A or B) has power failure
(the super capacitor is discharged after approx. 6-12 hours)
DISTANCES OVER 40 METERS
(see appendix 1 for working range details)
Figure 4. If the distance between unit A and unit B is over 40 meters and no unidentified
object is present, unit A and unit B is in NO alarm state.

FUNCTION – one moving crane
If there is only one moving crane to be protected from running into a wall or a track end, the
configuration with one complete unit A and one transponder unit B can be used. The
modulated (fingerprint) reflection to the active unit is made by a diode in the transponder
microwave head. The diode oscillate with 16 kHz. As long as the diode oscillates, the
opposite active unit recognize the unit.
Figure 5A. Unit A is a complete system with relay box. Unit A transmits an unmodulated
Microwave signal to Transponder Unit B (no relay box needed).
Figure 5B. Transponder Unit B (without relay box) modulates the Microwave signal, Unit A
receives the modulated reflection.
When unit A is in the range for the modulated reflection, Limit 1 and Limit 2 will activate at
preset limits.

INSTALLATION
The location and alignment of the antennas is important, the location of the Relay boxes is
not critical. The antennas must be placed opposite of each other. The reflector has three
fitting holes suited for 8 mm bolts (not included in delivery).
A good location is often the barrier of a platform or a ladder, the barrier of the girder etc.
provided that they are rigid and not resonant when the crane moves.
If the crane has the ground/earth terminated to the crane construction, the GII antenna
(reflector) shall be isolated by rubber bumps or equal, when fixed with the three bolts in
the crane.
For correct detection of the unmodulated signal reflection (in case of error in one unit), it
is necessary to have a surface of metal with minimum 1 m² behind the antennas. A plate of
1 m² or larger can be installed behind the antennas, if the location of the installation do
not have enough surface of metal behind the antennas. See figure below.

Page 12 / 42
User manual GII Anti-Collision System
To have easy access to the antenna box is also recommended.
The antennas are to be mounted with their main-beam axis parallel to the crane travelling
direction, and free from other fixed or moving objects within a radius of 1,5 m from the
main-beam axis center.
The moving trolley or trolley cables must not cross the antenna beam.
1,5 m free space around the antennas is necessary, both at the location for installation and
along the crane travelling track, to get correct transmitting/receiving of the microwaves.
See figure below.
It is suitable to have the cranes close to each other when installing the antennas. To adjust
the alignment of the antennas, washers or nuts can be used on the backside of the reflector
(mounted on the three 8mm bolts). A laser water level pointer is a good tool to help up the
alignment.

INSTALLATION - ALIGNMENT PROCEDURE
REFLECTOR no. 1:
Step 1 (reflector no. 1)
Fit the reflector no. 1 on the crane with three 8 mm
bolts. Use a water level indicator to align the
reflector (see figure 1).
Step 2 (reflector no. 1)
Use two of the assembly hex screws (intended for the antenna box) mounted on the
reflector no. 1 to support and align the laser water level pointer (see figure 2).
Check the alignment of the reflector no.1. Use washers or adjust the nuts if needed to align
correctly (see figure 3).

User manual GII Anti-Collision System
Step 3 (reflector no. 1)
Fit a piece of white A4 paper sheet on the other crane (or on the wall if a transponder unit is
used), indicating the laser point from the laser water level pointer in the middle.
Run the cranes apart from each other and check that the laser point stays within the A4
paper sheet. Add/remove washers or adjust the nuts to align reflector no. 1 if needed.
Do not remove the laser water level pointer from reflector no. 1 yet!
REFLECTOR no. 2:
Step 4 (reflector no. 2)
Run the opposite crane close to the crane with
the installed reflector no. 1.
Install the reflector no. 2 in the position
indicated from the laser water level pointer
(fitted on reflector no. 1). see figure 4.
Step 5 (reflector no. 2)
Use the water level indicator to align reflector no.2
(see figure 5).

User manual GII Anti-Collision System
Step 6 (reflector no. 2)
Use two of the assembly hex screws (intended for the antenna box) mounted on the
reflector no. 2 to support and align the laser water level pointer (see figure 6).
Check the alignment of the reflector no.2. Use washers or adjust the nuts if needed to align
correctly (see figure 7).
Figure 7
Figure 6
Step 7 (reflector no. 2)
Run the cranes apart from each other and check that the laser point stays in the area of the
opposite reflector no 1.
Add/remove washers or adjust the nuts to align the reflector no. 2 if needed.
Step 8 Final alignment of the reflectors to achieve the strongest possible signal
This is a VERY IMPORTANT step!
Apply a washer (thickness 1 mm) on the left assembly point of reflector no. 1 and reflector
no.2, alternatively adjust the nut on the left assembly point 1mm. (see figure 8)
The Microwave spread is slightly to the left when the
reflectors are pointed straight in line to each other.
To achieve the strongest possible signal and to maintain the
signal if the cranes are turning slightly along the rails, the
reflectors should be aligned about 1,5 degrees to the right.
See figure 9 and 10, showing the Microwave spread.

Step 9 Final control of signal strength.
Check that the reference value for the signal strength (Str) is reached according to the
supplied test certificate. Position the cranes so that you can read 5m distance (dist) in the
relay box. If the signal strength is lower than what is stated in the test certificate, the
antennas need to be redrawn.

OPTIONAL - POWER BANK BACKUP OF THE MODULATED SIGNAL
The power shall, in normal cases, always be turned on, preferably the mains supply shall be
connected before the main contact on the crane. The integrated backup super capacitor can
only handle shorter power failures (a couple of hours, depending of temperature). In those
cases, when a longer period of shut down of a crane or the transponder unit version is not
possible to operate via mains supply 12 VDC, the external option, Power Bank backup of the
modulated signal can be used (purchased separately).
The modulated (fingerprint) reflection to the opposite unit is made by a diode in the
microwave head. The diode oscillate with 16 kHz. As long as the diode oscillates, the
opposite unit recognize the unit. The external Power bank feeds the diode with power and
make it oscillate.
Modification of antenna and transponder circuit boards for battery backup is necessary for
all systems with S/N 0650 and earlier.
From system S/N 0651 and later, antenna and transponder circuit boards are pre-modified
as standard.

It is recommended to set Limit 1 to at least 5 m less than the maximum range.
When distance is <5 meters, alarm limit L1 is constantly active, and will only be
released when the crane is in reversing direction.
As the crane is within <5 meters distance, the physical crane speed will be
higher than actual speed registered by the GII system.
The values for L1RS and L2RS may need to be increased in order for the crane to
be operable without reaching the alarm limits (L1 and L2).

Mode 1: the alarms for Limit 1 (relay 1) and Limit 2 (relay 2) will activate if the speed
exceeds the minimum speed limits L1rS and L2rS (see next page). The minimum speed limit
settings make it possible for two cranes to operate at slow speed close to each other (under
supervision of the crane driver) without triggering the alarms.
When the alarms for Limit 1 and Limit 2 have been activated (MSr = off), as the crane speed
is less than the minimum alarm speed settings (L1rS and L2rS), the alarms will not deactivate
until the speed is zero.
If menu “MSr” (Min Speed release) = OFF
When the alarms for Limit 1 and Limit 2 have been activated, the alarms will not deactivate
until the speed is zero, even if the crane speed is lower than the minimum speed settings
(L1rS and L2rS).
If menu “MSr” (Min Speed release) = ON
When the alarms for Limit 1 and Limit 2 have been activated, the alarms will deactivate as
soon as the crane speed is lower than the minimum speed settings (L1rS and L2rS).
Mode 2, the alarms are NOT speed dependent (L1rS and L2rS are inactive). The alarms for
Limit 1 and Limit 2 are active as long as the crane is within the range of the alarm limits. The
cranes can only run apart from each other when the alarms are active.
Mode 3: same function as mode 1 except for Limit 2.
Limit 2 will not deactivate automatically and must be reset by a control signal (24 VDC) to
the relay box.

Speed compensation in percent for Limit 1.
Range: 10 – 1500 % (step of 10%).
Minimum value is 10%.
S P d 2
0
Speed compensation in percent for Limit 2.
Range: 10 – 1500 % (step of 10%).
Minimum value is 10%.
To compensate the Limit 1 and Limit 2 for different speeds, the SPd1 and SPd2 settings can
be used. The higher the speed of the crane, the earlier the crane needs to brake and stop
in order to not exceed the (physical) alarm limits for brake and stop.
The compensation is active in all 3 modes.
This formula is used to calculate the compensation value:
The compensation value = (ABS Speed – SpeedCompStart)* SpeedCompLIM1)/100
ABS Speed = actual speed
SpeedCompStart = The speed which must be exceeded to start the compensation. Default
value is 0,1 m/s (can be changed by Gigasense AB).
SpeedCompLIM1 (SPd1) = Speed compensation value in percent, range 10 – 1500 % to be
set by the user.
E.g. If Limit 1 is set to 12 m, SpeedCompLIM1 (Spd1) is set to 50% and the actual speed is 1,5
m/sec. The Limit 1 will be compensated according to the calculation:
Limit 1 compensation = (1,5-0,1) *50)/100 = 0,7 m
When the crane operates in a speed at 1,5 m/sec, the Limit 1 will be moved 0,7 m
(to 12,7 m).
E.g. to get a longer braking distance.
LIM1 (with compensation) = 12 m + 0,7 m = 12,7 m
The same formula applies for Limit 2.

A. Park the crane at the same distance as set value in the
“UodI” menu to the opposite crane.
B. Simulate the opposite unit as a dead unit:
Disconnect the 12V power supply (1) protect the loose cable
from short circuit, disconnect the diode (2).

E. Reconnect the diode and the power cable.
Warning!
According to step “B”, it is NOT ENOUGH to turn off the mains supply,
to the opposite unit. The Super Capacitor operates the modulated

ADJUSTMENTS & TEST OF PERFORMANCE
Decide in which mode for the modulated- and unmodulated signals the system will operate.
Unless otherwise specified, the system is set to the following default settings at delivery:
- Mode 1
Set Limit 1 and Limit 2 to appropriate alarm distances.
Default settings are:
Limit 1 = 12 m
Limit 2 = 8 m
Set the minimum speed limits to the safe speed you want to use without being stopped by
the Anti-Collision System (Mode 1 and Mode 3).
Default settings are:
L1rS 1 = 0,1 m/s
L1rS 2 = 0,1 m/s
Set the speed compensation value, if you need to compensate for different speeds.
Default settings are:
SPd1 = 10 %
SPd2 = 10 %
Run the cranes along the track and check that the Limit 1 and Limit 2 alarms triggering at the
set distances. Check that no false alarm occurs.
MAINTENANCE
GIGASENSE II is designed to be maintenance free, and checking of the performance can
usually be made in the normal operation before the cranes are operated.
When the equipment is operated in severe environment, high temperature, high humidity
etc, it is however recommended that ocular inspection inside and outside of all parts is done
on a regular basis i.e. every 6 months.
In case of cleaning the equipment, this should be done by gently wiping it off with a dry or
damp cloth.

HIGH RISK APPLICATIONS
The GII system has MTTFd values which allows, under certain circumstances, to use the GII
system in high risk applications.
In this case, two Gigasense Systems operate in parallel (as two channels):
System 1: A-unit + B-unit
System 2: A-unit + B-unit.
The Gigasense Anti-Collision Systems are considered as sensors in the comprehensive safety
system. The digital output signals from the relay boxes, shall be connected to a safety
system.
The machine supplier is responsible to follow the machinery directive, applicable
standards and regulations for the complete system and installation.
