4.2.4.3 Running modes
The unit has three different running modes and one
block mode. The different running modes are selected
via the display or the PARUS software.
AUTO
In AUTO mode, the unit will operate automatically,
and the operator cannot initiate any sequences
manually.
TEST
When TEST mode is selected, a test sequence will
start. In this mode it is possible to perform two types
of tests: a Simple test or a Full test. The type of test is
selected in parameter 7040.
MANUAL
In MANUAL mode the unit will not initiate any
sequences automatically. It will only initiate
sequences, if external signals are given.
BLOCK
When BLOCK mode is selected, the unit is not able
to initiate any sequences, e.g. the start sequence.
BLOCK mode must be selected when maintenance
work is carried out on the genset.
4.2.4.4 Application modes
Island operation
– This operation mode is selected for local/remote
start applications, without the Mains (= stand-
alone).
– Combined with MANUAL mode = Local Start
operation.
• The sequence is: start / close generator breaker
(manually) / genset operation / open generator
breaker (manually) / open generator breaker /
stop.
– Combined with AUTO mode = Remote Start
operation.
• The remote start signal can be given with an
external switch. Before the generator will be
started, the generator breaker must be closed.
• Installation wiring for Remote Start operation:
wire the RS switch between X25.1 & X25.2.
4.2.4.5 Parameter settings
The parameter settings are pre-programmed. To
change parameter settings, a password is required.
Changing different parameters requires different
password levels. Some parameters cannot be changed
by the end-customer because of safety reasons.
The Qc1103™ provides three different password
levels:
– User password
– Service password
– Master password
A parameter cannot be entered with a password that is
ranking too low. But the parameter settings can be
displayed without password entry.
Consult the Qc1103™ user manual for all customer
level parameters, which can be accessed with the user
password. In order to receive the default parameters
for your unit, please contact Atlas Copco Service
staff.
To change a parameter:
1. Enter the Setup menu.
The test will be interrupted if the
mode is changed to either MANUAL
or AUTO.
The genset will shut down if
BLOCK mode is selected while the
genset is running.
