Atlas Copco XAS 67 Dd C3 APP User Manual

Start the unit in accordance with the normal
procedure (see section Starting / Stopping). Let the
motor warm up until it reaches operational
temperature. Turn the green switch S7 to position 1.
The normal control system is switched off and the
engine speed increases to reach the maximum.
The green lamp H3 in the switch S7 is activated,
showing that sockets X1.1, X1.2 and X1.3 are under
tension.
The generator can be switched off by turning the
green switch S7 to position 0.
Protective device
The generator is protected by circuit breakers that
switch off if a connected electrical device has an
electrical fault.
The insulation is monitored by relay K6.
When the yellow LED on the insulation monitoring
relay K6 is activated, it means that a serious insulation
fault has occured.
The insulation monitoring relay K6 is adjusted to
10 k. This adjustment may not be changed.
The generator temperature is monitored by a thermal
contact (S6).
Control panel (generator)
As soon as the generator is switched on, the automatic
control system will continuously check for electric
load in order to rev up the engine from idle to nominal
speed only when needed. This saves fuel and reduces
emissions.
What is more, with the current continuously
monitored, a consumer having just been switched on
is temporary disconnected from the generator to be
re-connected as soon as the engine reaches nominal
speed. This is a safety mechanism to protect generator
and engine below nominal speed.
Avoid high inductive loads (e.g.
welding). High inductive loads can
damage the generator.
