Running Modes
The running modes are selected using the buttons as follows:
Mode Description
SEMI
-
The display push-buttons (START, STOP, GB ON, GB OFF) are active and can
be used by the operator.
-
The regulators are also active, i.e. the speed control will bring the generator to
nominal speed upon start.
-
When pushing a breaker button for closing, the AGC 200 will synchronise (if
allowed) the breaker. When the breaker closes, the controls stop.
TEST
-
The unit will start the generator, carry out the test sequence (predefined time
period) and stop the generator again. Subsequently, the generator will return to
AUTO or SEMI-AUTO mode. The mains breaker will remain closed, and the
generator breaker will remain open. NOTE: The test running can be: Simple test:
starting the gen-set without closing the GB, Load test: Parallel to the mains and
take load to a predefined value. Full test: Transfer the load to the gen-set and
open the MB.
AUTO
-
The unit will automatically carry out the control type selected (AMF, fixed power
etc.).
- The display control push-buttons (START, STOP, GB ON, GB OFF) are
disabled.
-
If the selected running mode is fixed power, mains power export, load take over
or island, timer start/stop (week watch) or binary input, then start/stop can be
used.
MAN
-
The display push-buttons (START, STOP) are active and can be used by the
operator.
-
The regulators are not active, i.e. speed (and voltage) control has to take place
using external controls for generator speed and possibly generator voltage
control.
-
The breakers will be able to open or close at any time. A synchronisation check
will always be performed to ensure safe closing of the breakers.
OFF
-
The unit will not be able to start. OFF mode can be selected during standstill and
the password is needed to go away from OFF mode. If the OFF mode is
selected while the gen-set is running, the mode will have no effect until the gen-
set is stopped. To select another mode after the OFF mode, the password must
be entered.
