INTRODUCTION

1 SAFETY GUIDELINES

CARRYING OUT INSTALLATION AND MAINTENANCE OPERATIONS WITHOUT DISCONNEC­TING 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 compli­ance 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, am­mable, 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.

INSTALLATION

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

3.1 Electric connections

The tank lling system must be connected using the supplied cables.

- Remove the protection cap from the valve

- Position seal (1 in 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 (4 in 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.

INSTALLATION

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 pres­sure 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 car­ried 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.

INSTALLATION

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 A and

B can 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 B stop

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.
