Operational Principal
The
SkidWeigh ED2E-EP / DL2E-EP
system operation principal is
based on the hydraulic pressure transducer mounted in the vehicle
lifting hydraulic circuit. The increase in the hydraulic pressure will
activate the specific “weighing cycle” algorithm and initiate automatic
motion control of the hydraulic lift motor. The microprocessor will take a
readout of the predetermined valid pressure transducer input at a
sample rate of 16000 readings per measurement session and will
convert it to the load weight that will be shown on LED display.
Pressure Transducer Installation
The pressure transducer must be installed in the lifting hydraulic line
between the lift control valve and lift cylinder.
Mount a T-piece in hydraulic line for the installation of the pressure transducer.
2 Methods for Automatic Pump Motor De-Activation During Load
Weighing Cycle
Two
BLACK wires
are connected to the internal relay located in the
ED2E-EP / DL2E-EP
digital indicator. The inter-
nal relay is controlled by the microprocessor and activated only during the load weighing cycle.
There is no power
connected to these two BLACK wires !
I
nternal relay configuration is SPDT.
Method A.
(Preferred Method)
Use the two
BLACK wires to “splice” them in series
with the operator activated
lift control switch
wire or signal
wire from the electronic controller that is activating the lift pump motor solenoid.
Note:
The predetermined motion of the lifting cylinder and the load weight measurement “weighing cycle” will be
initiated and controlled automatically by the software algorithm based on the input signal from the pressure trans-
ducer. Once the load weight is shown on the LED display the internal relay will be de-activated and the lift pump
motion control will be back to normal operation .
(With the vehicle at a stationary position during the lifting cycle
diagnostic display on some vehicles may show ‘No power to lift motor’ or audio signal might be activated for
short time period.)
