1 INTRODUCTION
This manual contains the installation and set-up instructions for the Series 1-L Total Moment
Indicator.
Installation should only be carried out by competent and trained sta as this product is a
safety product.
During installation it is assumed that industry standards will be observed and all cabling will
be protected against damage either from the movement of the machine or from collisions
that may occur during
normal operations (trees & branches, etc.)
All welding or bare metalwork should be treated to ensure that rust does not form.
1.1 System Layout
The system layout depends on which version of the Series 1-L is being installed.
• For the series 1 system layout, refer to page 9.
• For the series 2 system layout, refer to page 10.

2 COMPONENT IDENTIFICATION
2.1 Series 1-L Display
The display unit utilizes a 4 LED indication of tipping moment based on 50 to 105 % of the
Alarm threshold. (As default, this is set to 66% of the hydraulic limit of the machine).
Indicates 105% of Alarm threshold
Indicates 100% of Alarm threshold
Indicates 75% of Alarm threshold
Indicates 50% of Alarm threshold
Indicates System Power is ON
Test Button:
When pressed and held, will make the LEDs
cycle from 50% green through to 105% RED
2.2 Angle Sensor
The Angle sensor should be fitted to the first excavator boom and
connected to the pressure transducer that is fitted to the main lift rams.
The sensor is connected to the display via a M12 0CAN bus cable. An LED
on the Angle Sensor flashes green to show that it is powered and working
correctly. Where possible, ensure that the green LED on the Angle Sensor
is visible during operation to show the Angle Sensor is working correctly.
2.3 Pressure Transducer
A pressure transducer is used to monitor the forward hydraulic pressure
in the boom lift ram. The pressure sensor connects to the angle sensor
module by a 4 way M12 cable. The forward pressure reading directly relates
to the load lifted by the machine. The sensor measures up to 400 Bar.
A second pressure transducer may be required to monitor the reverse side pressure ( rod
side ) for additional pressure compensation.
2.4 CAN to USB Interface
A USB to CAN Converter Interface is used to allow a PC to communicate
with the Series 1-L during initial set-up and for later monitoring purposes.
IMPORTANT NOTE: ENSURE USB DRIVERS ARE INSTALLED
FOR THE USB TO CAN CONVERTER. SEE GKD USB DRIVER

3 INSTALLATION
3.1 Series 1-L Display
The back of the display is fitted with a ball-joint mount. The joint base should be secured
with 2 x M5 bolts on fixing holes at 48.5mm spacing, and can be mounted on a horizontal,
angled, or vertical surface as appropriate. The display should be mounted within easy reach
of the operator, in a position that avoids direct sunlight on the indicator LEDs and exposure
to water ingress. Care should be taken to
ensure that the display is mounted to a surface or structure that is capable of supporting the
display when travelling over rough terrain.
A 2m long cable carries the DC supply and Change-over relay contact signals. The DC
Positive supply should be connected to an ignition switched power source and be protected
by a 5A fuse.
A 4 core, M12 cable is supplied to connect the Series 1-L Control Unit to the Angle Sensor.
Dierent lengths of cable, or extension cables are available as required on any particular
machine. The cable should be protected from physical damage during machine operation.
3.2 Angle Sensor
The sensor monitors the angle of an imaginary line drawn between the two articulation
points of the boom. For the best operation the sensor should be installed with the long edge
parallel to this imaginary line. Position and oset from the imaginary line should achieve the
best location taking factors such as cable runs and protection into consideration.
The sensor is provided with a mounting bracket that should be welded to the boom and
painted to the boom colour.
A green LED on the Angle Sensor flashes when it is working correctly. An M12 cable then
runs from the Angle Sensor to the pressure sensor M12 connector.
Diagrams show typical angle sensor Pre-boom (stub) locations and orientations.

3.3 Pressure Sensor
Pressure sensors use a G1/4 hydraulic interface to the machine hydraulics.
The ram full side pressure transducer, and the optional reverse side (rod side) pressure
transducer, must measure the pressure in the lift ram at all times. Therefore, the measuring
point must be on the ram side of any hose burst check valves that may be fitted. This port
is often designated with an ‘E” stamped into the valve body. If in doubt check. [Note hoses
should be fitted with restrictors (typically with a 0.75mm hole) to control the rate of descent
of the boom in the event of failure of the balance hose].
The pressure sensors should be mounted in such a position that the electrical connector may
be accessed and the cable securely routed. The mounting position should also protect against
damage caused by persons climbing the machine or other objects striking the machine.
Typical pressure transducer installations.
3.4 Alarm
The alarm is wired as a relay change over contact output and uses 3 wires in the Series
1-L Display power cable. The output has a limited current capability of 1A. Any alarm that
exceeds this current capability will need to be controlled via another relay.

APPENDIX - GKD USB DRIVER INSTALLATION
Introduction
The GKD USB to CAN Converter includes an FTDI USB interface chip and a special Windows
driver is needed to allow the GKD Series 1-L PC software to use a USB port to talk to the
Series 1-L Display Unit. This note details how the driver software can be installed.
Windows version
The version of USB Driver required for a particular PC may depend on which version of
Windows operating system is installed on that PC. Many modern computers with Internet
access may automatically search for a suitable driver on the internet and install it for you.
Older PCs, or where there is no Internet access, may require the drivers to be available on
the PC already and a Windows Driver Installation Wizard told where to look for the driver.
Note that ONLY Windows XP, Vista & Windows 7 are supported.
Plug in USB to CAN Converter and install drivers
Plug the USB to CAN converter into a USB port and a Found New Hardware report is seen
indicating a USB Serial port. A Found New Hardware Wizard appears, as shown below:
If the PC has Internet Access you may be able to set the “Yes, this time only” button and
click Next for the PC to find and install the right driver. Advice may also be obtained from
the FTDI website on how to obtain a suitable VCP driver for their USB chip.
If there is no Internet Access, or a driver can’t be found then at this stage click the “No, not
this time” button and Next. A new screen appears asking for the location of the driver file.
If Windows can’t find a driver load driver interface files onto PC
If windows can’t find a driver, or there is no internet access, GKD supplies driver files on a
CD. Create a new “USB Driver” folder on the PC, typically entitled C:\USB Drivers, and load
GKD’s driver folder from the CD into that folder. The folder is typically called “USB FTDI
Drivers”.
In the “USB FTDI Drivers” folder there should be two .pdf files that give instructions for
Windows XP and Windows 7 Computers Installations. Typically run the setup file:
CDM 20814_ Setup.exe to run the installation file & load drivers.
