Page 6: Principles
Principles 4.1 How the hydrualic system works The RCS is an hydraulic weighing system for forklift trucks and stackers. The load measurement system measures the oil pressure with an oil pressure sensor. The pressure in the lifting system depends on the load on the fork lift system. By measuring the oil pressure in the cylinder, you will get an indication of the weight that you are lifting. -

20 reading steps; Make sure the system is relieved before beginning a new weighting; • If the RCS sytem is installed on a new lifttruck, it is recommended that you perform a • recalibration after 3 months and 1 year. -
Page 8: Overview Of The Parts
Overview of the parts The RCS weighingsystem exists of two main parts: 1. Indicator 2. Sensor The sensor has to be connected to a T-link on the hydraulic system of the forklifttruck. The indicator, the controlpanel, runs on 6 Volt batteries. On the drawing below you can find the parts of this sytem. - Page 9 Type B: 2 cylinders on both sides Indicator hydraulic Hydraulisch valve block ventielblok T-stuk t-part Sensor sensor cable Sensorkabel USER MANUAL – RCS...

Page 10: Before Installation
Check the forklift truck on the following points before you begin the installation: Capacity of the forklift truck The RCS system can be installed on a forklifttruck with a maximum capacity of 99 ton. Maximum pressure in the hydraulic system The RCS works optimally at an oil pressure up to 350 bar. -
Page 11: The Condition Of The Mechanical Parts Of The Fork-Lift Truck
The condition of the mechanical parts of the fork-lift truck After you have installed the RCS on the forklift truck, the truck will be part of the weighing system. Especially the mechanical parts of the forklift truck, such as the mast, the mast rollers and the ball bearings can influence the accuracy of the weightings. -

Questions and answers
printer printing automatically
The Ravas RCS printer prints automatically when the weight in the display is stable, as indicated by the “load stable” signal. This prevents errors from weighing or printing while the load is moving.
