Safety
Always disconnect the vehicle battery while installing SkidWeigh system or any other electronic product.
Make sure that unit, 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 SkidWeigh 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)
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. This product 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.

Overview of components
The standard ED3 / ED4 SkidWeigh Plus check weighing 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
!
Load weight operational principal
The ED3 / ED4 SkidWeigh Plus series load weight 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.
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 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 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) is 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 with the anti vibration mount and fasten digital indicator on the vehicle dashboard, side railing
on the right hand side or preferably on the overhead 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.
Choose the correct location and make sure that:
- Indicator is visible and within reach of the operator
- Location so that operator has a clear unobstructed view of the working environment
!
Compact size
All of the SkidWeigh systems are compact, housing dimension of only 120 x 80 x 55 mm is ideal for the installations to
material handling vehicles of all kinds.
Electrical connections
All SkidWeigh RFID equipped systems operate from 12 to 55 VDC.
Digital indicator with eight wires single cable
-
Orange Wire (+) Ignition switch On position
- Brown Wire (-) Battery negative
- Red Wire, connect to RED wire of the pressure transducer cable

Vehicle Disable Function
Internal relay SPST N.O. dry contacts, rating 1A.
This relay will be activated and stay on once the valid operator ID# is inputed
into the system.
To disable vehicle operation connect two wires, green and blue in series with
seat switch
- Green Wire
- Blue Wire
Pressure transducer cable
-
White Wire, pressure transducer signal 0 to 2,5 V
- Black Wire, signal negative
- Red Wire, power supply + 11 V DC
Male port 1/4”-18 NPT
!
All SkidWeigh systems are internally short circuit protected with resettable fuse. There is no need to install external
inline fuse in orange wire that is connected to the ignition switch.
Note:
ED3 ED4 Keypad Operator Access Control SkidWeigh Plus system is utilizing keypad as the
input for the operator access control. System capability is for input of 150 valid operators ID numbers, 3 digits maximum, range from 1 to 999. All new systems are supplied with valid
operator default ID# 111. This default ID# number 111 is needed to access ADMINISTRATION MENU and set up and calibrate the system.
