Compressed Air Connection (Figure 3.13); External Dosing (Option); External Dosing Equipment Connection To The Washer - GIRBAU HS-6040 Installation Instructions Manual

Compressed air connection (Figure 3.13)

Models HS-6040 TILT; EH090 TILT; HS-6057 TILT; EH130 TILT; HS-
6110; EH255

Assemble the pressure gauge A and seal the thread with Teflon or
other sealing component.

Pressure (min-max.): 6-7 bar, (87-100 PSI). The machine is provided
with a filter and pressure regulator.

The Compressed Air inlet connection to the machine must be done
with a flexible tube of 10 mm of inner diameter, secured to the
connection adapter B with a clamp.

See Installation specifications (section 1.4) of the corresponding model
for sections, dimensions and CA connection flow.

Insert in the supply pipe and in an accessible place a MECHANICALLY
LOCKABLE MANUAL
maintenance operations or to be used during long periods of non
operation of the washer.
VERY IMPORTANT!
Although the machine is provided with a filter at the Compressed
Air inlet connection, it is of vital importance to supply to the
machine a completely dry air.
TILT MODELS
Air connection hoses to the machine must be flexible, capable of accommodating the washer
movements during the loading and unloading operations and secured at their ends.

External dosing (option)

The washer can communicate with external dosing equipment via electrical signals produced by the closure of
relay contacts during wash cycle.
The relay contacts close the circuit between a COMMON input in and each one of the outputs corresponding to
each one of the dosing that the washer program runs.
According to the characteristics of the external dosing equipment, two different connections can be used:

Dry contacts. Origin of the dosing signals: these proceed from an external supply source of the washer
(normally it is a signal coming from the external dosing equipment). The relay contacts act as dry
contacts.
Maximum values for the electricity supply: 240 V, 50/60 Hz; 1A.

Contacts powered from the washer control circuit. The external dosing control board incorporates a
connection point allowing to generate dosing signals from the washer control circuit.
Supply voltage: 200...240 V; 50/60 Hz depending on the washer.
Maximum connection intensity: 0.05 A.

3.6.1. External dosing equipment connection to the washer

Refer to the washer electrical diagram to locate the connection points.
Steps prior to connection:

Disconnect and mechanically lock the external automatic switch.

Open the terminal box A, (Figures 26 and 29) located on the back of the machine.

On the entry hole of the external dosing electrical supply (Ed identified in Figures 3.14 and 3.17) install a
lock mechanism (not supplied with the washer) to fasten the cable or cable pipe protector, depending on the
cable and pipe protector used. Refer to dimensions and connection diameter in INSTALLATION SPECS,
section 1.4.
Signal conductor

Characteristics of the signal conductor cable: 0,75 mm2 (#16-18 AWG), 400 V.

If using single-wire conductors, these must be encased within a safety conduit.

The conductor must be affixed to the inlet opening of the machine using a secure connection appropriate for
the type of conductor.

The conductor must be protected against traction, crushing and friction.

Additional specifications for the conductor: must comply with the statutory regulations of the country in which
it is to be installed.
