Q1 .......Circuit breaker for X1
Interrupts the power supply X1 when a
short-circuit occurs at the load side, or when
the overcurrent protection is activated.
When activated, Q1 interrupts the three
phases towards X1. It must be reset
manually after eliminating the problem.
X1 .......Main power supply (400 Vac)
Terminals L1, L2, L3, N (= neutral) and PE
(= earthing), hidden behind the control panel
door and behind a small transparent door.
N14 .....Insulation monitoring relay
Checks the insulation resistance and
activates Q1 when the insulation resistance
is too low.
S2 .......Emergency stop button
Push the button to stop the generator in case
of an emergency. When the button is
pressed, it must be unlocked, by turning it
anti-clockwise, before the generator can be
restarted. The emergency stop button can be
secured in the locked position with the key,
to avoid unauthorized use.
COSMOS™
COSMOS™ is a web-based global remote
monitoring system that electronically tracks every
aspect of equipment from its location to its operating
parameters. The Cosmos system can send e-mails or
SMS messages to the contractor or owner in real time,
with all critical and non-critical events and data
involving your compressors and generators. It allows
optimal servicing.
When starting up the generator, the green Power Led
(1) of the Cosmos module will light up when the
installation has been carried out correctly.
