NOTE: power supply should be a clean power supply. Too much disturbances and/or fluctuations on the
power supply line could damage the indicator. In case of doubt always contact your supplier!
The indicator has a regulator inside which regulates small voltage changes from 9VDC up to 36VDC.
The indicator consumes 350 mA (no options attached). A fuse of 0.5A is recommended in the 12VDC line.
1.1.5 Placing the battery packs in the iForks-Touch
1. Lift up the locking clips on the battery holders.
2. Position the batterypacks in both forks.
3. Click the batterypacks into the battery holders.
4. Push the locking clips down to secure the batterypacks.

To take the iForks-Touch in operation, the button (1.)must be pressed for about 3 seconds until the LED (2.)
lights up. After this the button has to be released. The LED will flash in defined Intervals. The iForks-Touch are
now ready and can communicate with the indicator.
The iForks-Touch has three different operating modes (On / Sleep / Off) and various status indication of the
current operating voltage that appears on the LED. Following table describes the operating modes:

.
If the supply voltage drops below 3.6 VDC, the iForks-Touch automatically and powers off and is no longer
ready for use.
1.1.6 Startup
Press -key to switch the terminal on.
After approx. 3 to 5 minutes the electronics and the loadcells have reached their operating temperature.
Before that deviations of up to 0.3% may occur.
Please set display to zero before weighing loads.
1.1.7 Operation
A fully charged battery provides power for approx. 80 hours of uninterrupted operation.
To avoid damages to the battery it should never be completely discharged. Deep discharge strongly reduces
the life time of the battery. Charging at regular intervals ensures full operational availability.
Charger: When the battery packs are being charged, the red LED is on. After the charging time of 8 hours
min. has elapsed, the charger is switched off and the batteries are fully charged. The LED signal turns from
red to green.
Important note: Both battery packs should always be charged at the same time!

1.1.8 Maintenance
The calibration of every scale must be checked at regular intervals. RAVAS recommends maintenance of the
weighing system once a year. Scales subject to Weights & Measures approval must be verified with certified
test weights every year by a certified organization.
The same rules that apply to a simple fork lift truck also apply to a weighing fork lift truck
In general:
Only clean the indicator with a soft clean cloth that has been dampened with a mild window type
cleaner. Do not use any type of industrial solvent, do not spray cleaner directly on the unit, do not
use water jets or the unit may be damaged.
To prevent damages to the weighing system make sure that any welding work on the unit is solely
carried out by RAVAS Service.
Never drive around without the batterie-packs installed. Dirt could settle on the battery contacts
which could prevent a proper supply to the transmitter modules in the forks resulting in errors on
the indicator display.
Check for wood chips between the upper weighing part and the lower part regulary.Remove any
wood chips present to avoid weighing inaccuracy.
Check the thickness of the forks regulary. If the thickness is too small new forks should be
installed to maintain the safety regulations.

2Weighing Terminal
This manual describes the basic functions and the operation of the iForks-Touch weighing terminal with the
operator interaction in the individual steps of the operating sequence. The terminal is intended for connection
to 12 V DC power supply (–15%) to 30VDC (+10%).
The weighing terminal supports power saving functions for battery operation:
On / off for printer;
Power off for display backlighting after time;
Power off for terminal when not in use after time;
Power off on battery low after warning.
2.1 Documentation
Apart from this documentation, additional information is provided in the following manuals:

2.2 Safety Advice
Read this manual carefully before you operate this instrument! Keep this manual for future
reference!
It must be installed, serviced, and operated in strict compliance with all locally applicable safety
regulations and the rules for the prevention of accidents!
When this unit is included as a component part of a system, the resulting system design must be
reviewed by qualified personnel who are familiar with the construction and operation of all
individual components in the system and the potential hazards involved. Failure to observe this
precaution could result in bodily injury!
All switch gear connected to the unit and/or installed close to it, such as relay and contactors,
must be fitted with appropriate components (RC-modules, diodes) to suppress interference.
In order to avoid static discharge, all metallic parts of a system must be thoroughly grounded.
Movable parts, such as portable scales on plastic wheels, must be grounded with earth clamps
or earth leads of appropriate diameter.
This module and its associated equipment must be installed, adjusted and maintained by
qualified personnel only!
Only permit qualified personnel to operate this instrument!
Disconnect all power to this instrument before cleaning and servicing!
Exercise utmost care when making checks tests and adjustments that can actuate movable
parts such as feeding devices, gates, flaps, conveyors, etc. Make absolutely sure that nobody is
within reach of movable parts. Failure to observe this precaution could result in bodily injury!
