Voltage Controller
The following screens are not found on the SPM-D2-10, SPM-D2-10/
N
. They utilize a three-position controller to
regulate the voltage. The SPM-D2-10/
X
& SPM-D2-10/
XN
have the option to utilize multiple methods of voltage
control. The following screens show the available methods of voltage regulation. The SPM-D2-10/
X
& SPM-D2-
10/
XN
will only display the screens related to the voltage controller type that is configured.

Voltage controller type
THREESTEP/ANALOG
THREESTEP
The voltage controller operates as a three-position controller and out-
puts raise (V+) and lower pulses (V-) via the corresponding relays.
The frequency and voltage controller cannot output signals at the same
time.
ANALOG
.... The voltage controller operates as a continuous controller with an ana-
log signal output (mA or V).
Note:
Only the screens, which pertain to the selected output signal type, will be dis-
played.

................ Generator voltage control is performed by the SPM-D2. The generator
voltage is controlled in various manners depending on the task (no
load / isolated operation / synchronization). The subsequent screens of
this function are displayed.
OFF
.............. Voltage control is not performed by the SPM-D2, and the subsequent
screens of this function are not displayed.

Voltage controller set point ramp
1 to 99 V/s
The controller increases the voltage from the initial set point to the configured volt-
age via a ramp. The slope of the ramp is used to determine how quickly the controller
changes the voltage. The larger the value configured here, the more rapid the change
in voltage.

No load/Isolated operation:
The generator voltage is controlled in such a manner
that when in a steady state the actual voltage does not deviate from the
configured generator rated voltage by more than the value configured
in this screen.
Synchronization:
The generator voltage is controlled in such a manner that, in a
steady state, the differential voltage does not deviate from the voltage
set point by more than the value configured in this screen.. The mains
or busbar voltage is used as the set point value.
