10. For fill heads with limit switch, check

whether the release pin (8) is present

and functional.

NOTE

The release pin can stick or

harden due to the influence of chem-

icals. Therefore do not use the limit

switch with adhesive, hardening or crys-

tallizing chemicals.

11. In the case of conductive fill heads,

check whether a conductive dip tube

is installed and whether it is properly

grounded.

Follow the ATEX and OSHA instruc-

tions and regulations.

For further information, please refer

to the operating instructions of the dip

tube.

12. When using fill heads with an overfil-

ling sensor, check whether the sensor

in the housing is working properly. The

ventilation channel must be free of

any debris of the medium so that the

measuring field of the sensor is not

disturbed. A ventilation line must be

connected to the vent port so that no

medium can escape unhindered in the

event of overfilling.

Assembly/commissioning

5.3 Mounting the fill head

WARNING

Hazard from chemicals!

Chemicals can cause irritation and

chemical burns.
• Observe the proper Standard Operat-

ing Procedures (SOP) when handling

hazardous substances.

• Observe the safety data sheets (SDS)

of the chemicals used.

• Wear the necessary personal pro-

tective equipment (PPE) (suitable

protective clothing, protective gloves,

respirators and safety goggles / face

shield).

1. If a tamper-proof cap is fitted to the dip

tube closure of the container, remove

the blue seal on the original tam-

per-proof cap (1).
