Work Environment Conditions; Electrical And Pneumatic Hook-Up - Cormach LIGRO Manual De Uso

Work environment conditions

- Relative humidity from 30% to 95% without
condensation.
- Temperature range from 0°C to 50°C.
WARNING
Use of the machine in a potentially explo-
sive atmosphere is not permitted.
ELECTRICAL AND
PNEUMATIC HOOK-UP
WARNING
All operations required for the electrical
hook-up of the machine to the power
supply must be carried out exclusively by
qualified personnel.
- The dimensions of the electric hook-up used
must be suitably sized in relation to:
- the electric power consumption of the
machine specified on the relative ma-
chine data plate.
- the distance between the machine and
the power supply hook-up point, to en-
sure that voltage drops under full load
do not exceed 4% (10% during start-up)
relative to the rated voltage indicated on
the specifications plate.
The operator must:
- fit a power plug onto the power cable in
compliance with applicable legislation
- connect the machine to its own dedi-
cated power supply outlet equipped with
a specific type A or B differential circuit-
breaker (with sensitivity of 30 mA).
IMPORTANT: only the specified type A
and B security breakers will be tripped
correctly in response to all the failure cur-
rents which may occur on the
- install protection fuses on the power line
that are suitably sized in accordance with the
38
indications given in the general electrical
layout diagram included in this manual
- ensure that the workshop electrical system
includes a functional grounding circuit.
- to prevent unauthorised use of the ma-
chine, always disconnect the mains plug
when the machine is not used (switched
off) for extended periods of time.
- if the machine is connected directly to
the power supply by means of the main
electrical panel and without the use of a
plug, install a key-operated switch or suit-
able lock-out device to restrict machine
use exclusively to qualified personnel.
For correct machine operation the com-
pressed air supply line must provide a
pressure range from no less than 8 bar to
no more than 16 bar.
NOTE
The machine is equipped with a pressure
regulator set at 10 bar (standard machine
operation). When working with easily de-
formable rims (such as vintage car wheels,
for example) we recommend temporarily
lowering the pressure to 7 - 8 bar.
An effective earth connection is essen-
tial in order for the machine to function
correctly.
NEVER connect the grounding line to
gas or water lines, to telephone wires,
or to other non-suitable objects.
Before making the electrical and pneumat-
ic hook-ups, make sure that the machine is
configured as described below (fig.5):
- pedals A and B (if present) in fully de-
pressed position.
- column C vertical (not tilted).
