SUMMARY

1 SAFETY GUIDELINES
CARRYING OUT INSTALLATION AND MAINTENANCE OPERATIONS WITHOUT DISCONNEC-
TING THE VALVE FROM ITS POWER SUPPLY MAY CAUSE SEVERE INJURY.
Do not operate the valve with no load for long periods of time, as this might damage the
components inside the valve.
ARAG can not be held responsible for direct or indirect damage caused by the type of uids
used for spraying and crop spraying applications.
These products are used under the exclusive responsibility of the operator, who must make
sure that all safety prescriptions indicated on the product label are complied with and that
suitable personal protective equipment (such as gloves, overalls, boots, helmet, etc.) is worn
at all times in compliance with the applicable legal requirements.
The tank lling system can detect the passage of conductive uids with a conductivity equal
to or higher than 300 μS/cm.
- Do not place the equipment under pressurized water.
- Comply with the specied power voltage (12 Vdc).
- If arc welding is needed, make sure that the power supply to the tank lling system is
disconnected; if necessary disconnect power cables.
- Use the tank lling system only within recommended rate range (Tab. 1, Pag. 13). Outside
this range, the tank lling system may provide incorrect data, thus misleading the operator
or the automatic system.
ARAG can not be held responsible for damage caused to persons, animals or things from
the incorrect or unintended use of the tank lling system or its parts.
2 PRODUCT DESCRIPTION
The movable tank lling system measures and displays on its screen a pre-established quantity of
uid and stops tank lling when the set quantity is reached.Through electromagnetic measurement,
the tank lling system (which features no moving mechanical parts) emits a signal that is proportional
to the ow of uid passing through it. The
owmeter displays the relevant owrate, which is calculated according to the impulses generated
and the value of the owmeter constant previously set.
2.1 Intended use
This device is designed for agricultural use. The machine is designed and built in compli-
ance with EN ISO 14982 standard (Electromagnetic compatibility - Forestry and farming
machines), harmonized with 2004/108/EC Directive and in compliance with 2006/42/EC
Directive.
The tank lling system must not be used to measure the passage of hydrocarbons, am-
mable, explosive or toxic liquids. The tank lling system is not suitable for contact with
liquids for human consumption. Use for sales transactions is not allowed.
INTRODUCTION

5
3 INSTALLATION
The tank lling system must be connected by means of suitable ttings (With female fork coupling)
to a pump, which will supply the liquid to be poured into the tank.
Install the tank lling system at least 20 cm from the elements that could cause turbulence inside
the tubes (valves, bends, constrictions, etc.).
WARNING:
- Rest the tank lling system on a horizontal surface
- The system to which it is connected must have a ltering element with a lter of at
least 50 mesh, together with a safety valve to limit use pressure at the specied max.
value (12 bar).
CAUTION:
ARAG is not liable for damage to the system, persons, animals or things caused by
the use of material other than specied.
Failure to observe the above instructions automatically voids the warranty.
INSTALLATION

6
3.1 Electric connections
The tank lling system must be connected using the supplied cables.
- Remove the protection cap from the valve
- Position seal (1in Fig.A) onto connector (2 in Fig.A), then connect the latter pressing it fully home
(3 in Fig. A). During this operation, take special care not to bend valve electric contacts.
- Fasten screw (4in Fig. A) until it is tightened.
CAUTION: If the gasket is not positioned correctly, there may be inltrations of water
in the connector and in the valve, with the consequent risk of damage to the device.
DO NOT CONNECT THE POWER SUPPLY USING DIRECT FASTON CONNECTORS.

3.2 Hydraulic connections
3.2.1 General warnings
Avoid bends and constrictions before connections and on tubes.
Do not use the tank lling system with pressure values over 12 bar.
Regarding connections, use tubes and ttings properly sized for the operating pres-
sure of the system.
Use Arag T6 ttings (see general catalogue) with female fork coupling. Do not use
elbow ttings.
WARNING: For the implementation on already operating systems it is necessary to
follow all safety rules described herein. System assembly and start-up must be car-
ried out by expert personnel according to the safety rules so as to ensure the same
safety level of the system.
3.2.2 Hydraulic connections
Connect inlet pipes to the valve and outlet pipes from the owmeter, using suitable connectors.
Take special care, where requested, to insert the O-ring correctly. If, for any reason, the pipes leak
at connection points, apply unsintered PTFE tape to improve sealing.

3.4 Monitor rotation
In case of vertical assembly, to simplify
the use of the DigiWolf it is possible to
rotate the monitor by 90° with respect to
the body.
1) Remove the fork from the monitor using a screwdriver.
2) Remove the monitor from the owmeter body.
If the monitor is turned upside down, the letters Aand
Bcan be seen: these correspond to the two possible
monitor positions (parallel and perpendicular to the
body).
DigiWolf is supplied with the sensor in position A(paral-
lel to the body).
With the aid of a screwdriver, loosen the screw locking
the sensor without removing it.
Rotate the sensor anti-clockwise until reaching Bstop
position.
Tighten back the screw without forcing it. The monitor
is ready to be tted in perpendicular position to the body.
Fit the monitor back on the owmeter body.

6 PRELIMINARY SETUP FOR USE
For a correct display of data regarding treatment, some preliminary set ups are necessary when
installing DigiWolf on farming machines.
6.1 Operating mode selection (FILLING / FLOWRATE)
DigiWolf can be used to measure the owrate of a uid in a hydraulic circuit ("Flowrate" mode), or
to control the lling of a tank by stopping the introduction of liquid once the set quantity has been
reached ("Filling" mode).
Some menu items will be available or not according to the set mode.

7.1.1 Valve activation time
It is possible to set the lling valve activation time, i.e. the time interval between the sending of
valve closure signal and the ow actual interruption, so that DigiWolf can calculate the exact time
of operation and therefore the quantity introduced.
The value to be entered is indicated in the technical sheet of the lling valve installed in the system.

limits, the ow-meter may give out incorrect data.
-To avoid damaging the owmeter, do not exceed the maximum rate except for short periods.
ARAG can not be held responsible for damage caused to persons, animals or things from
the incorrect or unintended use of Digiwolf or its parts.
- Do not exceed the max. operation pressure (12 bar).
Display of the symbol ------ shows that the rate or the totalizer are over the max. di-

9 OTHER SETTINGS
What follows applies to both operating modes of the owmeter.
9.1 Calibration
Rate reading may not be correct due to different system congurations (tubes,
valve, etc.). Therefore, we recommend to make a spray test; in case the measured
value is different from the real one, perform an automatic calibration procedure or
manually calculate owrate constant.
9.1.1 Automatic calibration
Make a quantity of liquid previously measured or that can be measured with another system
go through the owmeter.The greater the amount of liquid used to perform the calibration
procedure, the more accurate the calibration.

A) Press to toggle from one digit to another
B) Press in succession to modify the value of the digit highlighted by the cursor
C) Press to complete calibration procedure, or D) Press for 1 sec. to cancel calibration procedure.
If, after starting calibration, the device does not sense any ow passage (and the display
remains in 0), press OK to exit the calibration procedure without saving.
If the device continues to sense the liquid ow after pressing OK, after a few seconds
the error message Stop flow!will be displayed.
Once the ow has been interrupted, the reading will stabilize as by standard procedure.
