Safety
Always disconnect the vehicle battery while installing ED7 system or any other electronic product. Make
sure that indicator, pressure transducer and any other associated cables are securely mounted and do
not impede any of the vehicle’s controls. Use care when routing the components cables. Route the cables
where they will be protected. Use commonly accepted install practices for after market industrial vehicle
electronic devices. The installation of the SkidFleet systems should only be performed by an
acknowledged lift truck dealer technician or end user electro and hydraulic technical installer.
Here are two acceptable methods of making a wire connections:
* Soldering your connections (recommended)
* Crimp connectors (with the use of the proper crimping tool)

SkidWeigh ED7 Functions

Regardless of the method you choose, ensure that the connection is mechanically sound and properly insulated. Use
high quality electrical tape and shrink tubing where necessary.
The system is connected directly to the vehicle’s ignition switch, 12 to 55 VDC. There is no on/off switch on the unit.
Electro-Magnetic Compatibility
CE conformity to EC directive 89/336 (EMC) by application of harmonized standards: Interference stability EN
61000-6-2 and EN 61326-1 interference emit EN 61000-6-3, EN 61326-1 for the pressure transducer.

Our policy is one of continuous improvement and the information in this document is subject to change without notice.
Check that software version displayed on LCD is the one applicable for your application.
Overview of components
The standard SkidWeigh ED7 system consist of two main components:
* Digital indicator with wiring harness, mounting bracket
* Hydraulic pressure transducer with 3 wires cable
* Installation & calibration manual and operator usage instruction
Operational principal
The SkidWeigh ED7 system check weighing operational principal is based on the hydraulic pressure transducer
mounted in the vehicle lifting hydraulic circuit that will automatically activate the “weighing cycle / specific algorithm ”
every time a skid load is lifted just above the ground. The increase in pressure is converted in an electronic signal at
the sample rate of 16000 readings which is converted into a load weight reading. The ED7 system optional
equipped with the optional impact detection system have the impact module mounted inside the instrument
enclosure.
Pressure transducer installation
The pressure transducer must be installed in the lifting hydraulic line between the lift control valve and lift cylinder(s).
Mount a T-piece in lifting hydraulic line. In some cases you can install the pressure transducer in the flow divider,
drilling and tapping for 1/4”-18 NPT male in spare plug (if only single or double mast configuration) or in the body of
the flow divider. Also, you can drill and tap on any “larger elbow” that might be available in the hydraulic lifting circuit
found in vehicles with larger hydraulic hoses to accommodate larger vehicle lifting capacities.

Pressure transducer installation precautions
Before installation of the pressure transducer the hydraulic lift circuit must be pressure free.
There are two ways to do that:
1. Place the forks on the ground in their lowest position and make the hydraulic system pressure free by tilting the
mast forward. The chain(s) should be slack.
2. Lift the forks and position them on the top of a supporting fixture. Start lowering the lifting cylinder into its lowest
position. Be sure that chain(s) are slack.
Make sure that that installed pressure transducer will not touch any moving parts or assembly of the vehicle while in
normal operation. Pressure transducer has 1/4”-18 NPT male thread. Use thread seal to ensure tight fit.
Selecting the mounting location for digital indicator
Use the mounting bracket to fasten digital indicator on the vehicle dashboard, side railing or preferably on the top of
the operator guard.
!
There are many examples of mounting locations that will depend on the vehicle model. However, additional mounting
items such as a flat brackets may be needed to help secure the unit to upper right corner of the guard or side railing.

Power supply

Electrical power short circuit protection
- All of the ED7 systems are internally short circuit protected with resettable fuse. There is no need to install external
inline fuse in orange wire connected to the ignition switch, vehicle positive connection 12 to 55 VDC.
-Automotive 60 V load dump protection. Reversal power supply protection.
“Quick test to determine if electrical connections are done correct”
After you have connected electrical power and pressure transducer cable you can check the system operation.
- Turn on ignition switch.
- Tap on Home icon and than tap on the “Clock & More” icon shown on LCD
display home page.
- Tap on “Pressure Transducer Test”. LCD display will show digital readout
change as forks are lifted and lowered.
-If the above test is valid than the system pressure transducer electrical
connections are done right.
Note: If the readout shows 0 or only high readout number value over 65000, than
check wiring connection to the pressure transducer or replace pressure transducer.
Date / Time Set Up
Tap on the icon Clock & More shown on home page.
-Tap on the icon “Set Clock”.
- Use “Set” and “arrow up” and “arrow down” input to change time and date if
required
- When done tap on “Home” icon to save the values.
Vehicle ID#
-Tap on the icon “Admin”. - Password table will be shown.
- Input a following password: A123 and press “Next icon”.
- Input valid Vehicle ID#
Note: Maximum 4 digits !
- Tap on “Next icon” to confirm the vehicle ID#. Press Home icon.

General Instructions for Load Weight Calibration Procedure
To initiate calibration of the load measurement process you must press “Home” icon, and on the Home
page press “Calibrate” icon.
-For the best results use at least minimum known calibration load weight of 30 to 50% of maximum lifting capacity of
the lift truck. Use customer floor scale or find a known load weight within the operational facility.
Important:
If you want the system to show load weight in pounds, use the known load weight in pounds and
enter that value accordingly. The same would apply if you want the system to show load weight
in kilograms. ( Have known load weight nearby)
Calibration (Note: In our example a known calibration load weight is 4000.)
