Examples:
SPM-D2-1040B/YB (standard unit with 400 Vac PT measuring inputs, no CT inputs,
flush mounted, 24 Vdc power supply)
SPM-D2-1010B/NYB (standard unit with 100 Vac PT measuring inputs, no CT inputs,
flush mounted, 90 to 250 Vac / 120 to 375 Vdc power supply)
Intended Use The unit must only be operated as described in this manual. The prerequisite for a proper and safe
operation of the product is correct transportation, storage, and installation as well as careful operation and
maintenance.
NOTE
This manual has been developed for a unit equipped with all available options. Inputs/outputs,
functions, configuration screens and other details described, which do not exist on your unit,
may be ignored.
The present manual has been prepared to enable the installation and commissioning of the unit.
Because of the large variety of parameter settings, it is not possible to cover every possible
combination. The manual is therefore only a guide. In case of incorrect entries or a total loss of
functions, the default settings can be taken from the enclosed list of parameters at the rear of
this manual.

Chapter 3.
Electrostatic Discharge Awareness
All electronic equipment is static-sensitive, some components more than others. To protect these components
from static damage, you must take special precautions to minimize or eliminate electrostatic discharges.
Follow these precautions when working with or near the control.
1. Before doing maintenance on the electronic control, discharge the static electricity on your body to ground
by touching and holding a grounded metal object (pipes, cabinets, equipment, etc.).
2. Avoid the build-up of static electricity on your body by not wearing clothing made of synthetic materials.
Wear cotton or cotton-blend materials as much as possible because these do not store static electric charg-
es as much as synthetics.
3. Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoam cups, cup holders, cigarette
packages, cellophane wrappers, vinyl books or folders, plastic bottles, and plastic ash trays) away from the
control, the modules, and the work area as much as possible.
4. Opening the Control unit will void the warranty!
Do not remove the printed circuit board (PCB) from the control cabinet unless necessary. If you must re-
move the PCB from the control cabinet, follow these precautions:
Make sure that the unit is completely de-energized (all connectors have to be disconnected).
Do not touch any part of the PCB except the edges.
Do not touch the electrical conductors, connectors, or components with conductive devices or with bare
hands.
When replacing a PCB, keep the new PCB in the plastic antistatic protective bag it comes in until you
are ready to install it. Immediately after removing the old PCB from the control unit, place it in the an-
tistatic protective bag.
WARNING
To prevent damage to electronic components caused by improper handling, read and observe the pre-
cautions in Woodward manual 82715, Guide for Handling and Protection of Electronic Controls, Printed
Circuit Boards, and Modules.

Installation
CAUTION
A circuit breaker must be provided near to the unit and in a position easily accessible to the operator.
This must also bear a sign identifying it as an isolating switch for the unit.
NOTE
Connected inductive devices (such as operating current coils, undervoltage tripping units, or auxiliary
or power contacts) must be connected to a suitable interference suppressor.

Control Inputs
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Release CB
Terminal 3
Enabling for the operation of the power circuit breaker.
In order to enable synchronization or a dead bus start, this input must be en-
ergized.
Reply: CB is open
Terminal 4
The status of the CB must be transmitted to the control unit through this in-
put. The input must be energized if the CB is open. (The status of this input is
checked for plausibility and is indicated with the LED "Gen CB - ON".)
Enable: Dead bus start
Terminal 53
In order to carry out a dead bus start, this input must be energized.
Configuration locked
Terminal 6
Energizing this input avoids an unwanted switching into the configuration
mode by pressing "Digit" und "Cursor". For the setting, a detachable-key
switch can be used, for instance.
Synch-check
Terminal 54
By energizing this input, the unit is switched into the synchronization control
mode. While this operating mode is selected, there is no output of high-
er/lower orders of the three-position controllers. This means that no voltage
or frequency regulation is possible. The relay "synchronizing pulse: close CB
" will then work like a synch-check relay (see chapter "Control Outputs"
starting on page 20).
CAUTION
If several generators feed one busbar, it has to be ensured with external interlocking that only one of
the generators is released for dead bus start at a time. If several generators are released for dead bus
start at the same time, it may happen that the generator circuit breakers close at the same time, which
might cause serious damage to the generators!
Isolation of the Power Supply from the Discrete Inputs
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The common reference point for the discrete inputs (terminal 7) may be electrically isolated from the supply volt-
age (0V, terminal 2) through proper external wiring. This permits the control to utilize more than one voltage in
the control wiring. This is necessary for example if the supply voltage for the control is +24 Vdc and electrical
isolation of the system control voltage (e.g. 220 Vdc or 220 Vac) must be ensured.
The control should be wired as follows:
If the discrete inputs are to utilize the same voltage as the supply voltage:
Install a jumper between terminal 7 and terminal 2 (0 V)
If the supply voltage and control voltage are not the same ...
Terminal 2: connect to 0 V of the supply voltage
Terminal 7: connect to 0 V or N of the control voltage

Operating Conditions
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
No Load Control
With the relays of the three-position controller and speed switching appropriately, voltage and frequency of the
system U2 are adjusted to the configurable set point values. (Also see chapter "Table of Functions" starting on
page 16).
Synchronizing
The system U2 is adjusted to system U1 as far as voltage and frequency are concerned, the relays of the three-
position controller for voltage and speed switching correspondingly. Taking the switcher time element into ac-
count, the add-on order for the power circuit breaker is output in the synchronous point. The synchronization or
add-on is effected under the following conditions (also see chapter Table of Functions" on page 16):
The unit is in automatic mode (LED "automatic" is illuminated)
The synchronization function is enabled by configuration
Voltage and frequency of system U1 and U2 are within a certain range (see chapter "Table of Functions" start-
ing on page 16),
The discrete input "Release CB" is energized
The discrete input "Release: CB is open" is energized
The synchronization time monitoring is not enabled or has not expired
During the synchronization the unit may output a so-called kick pulse. The kick pulse is an individual pulse "raise
speed " The output of a kick pulse avoids that a status is maintained where the frequencies of the systems U1 and
U2 are almost equal for a long time, whereas the phase angle between the systems does not equal zero and re-
mains almost unchanged. In this state there is no synchronism and thus, no add-on of the power circuit breaker is
possible. Since in this case, the frequency controller does not output any actuating pulses, reaching the synchro-
nous point would take too long. With the output of a kick pulse the phase angle is changed. Thus, the synchronous
point is reached faster.

Dead Bus Start (Asynchronous Add-On)
Output of an add-on order for the power circuit breaker without synchronization, if the following conditions are
fulfilled:
The dead bus start function is in principle activated by configuration
One of the three possible dead bus start functions is selected by configuration
The discrete input "Dead bus start release" is energized
The discrete input "Release CB" is energized
The discrete input "Reply: CB is open" is energized
The conditions for one of the preset dead bus start functions are fulfilled:
a) U1 has the value Un (taking the configured rated voltage difference into account dV |V-Vrated|) and U2 is
zero (taking the configured zero voltage difference into account dV |V-0|).
b) U1 is zero (taking the configured zero voltage difference into account dV |V-0|) and U2 has the value Vrated
(taking the configured rated voltage difference into account dV |V-Vrated|).
c) U1 is zero and U2 is zero (taking each configured zero voltage difference into account dV |V-0|).
Moreover, in case a) and b) the frequency of U1 and U2 must be within the configured limits.
Synch-Check
In this condition, the unit can be used as a synchronization control. No control is carried out. The relay "CB
close" remains picked up, as long as the following conditions are met:
The voltage differential is within the configured limit
(screen "synchronization dVmax)
The frequency differential is within the configured limit
(screens "synchronization dfmax and dfmin")
The phase angle is within the configured limit
(screen "slip synchron. phimax")
The discrete input "Reply: CB is open" is energized
The discrete input "Enable CB" is energized
The systems U1 and U2 are within the permitted limits
(see Table 5-2: Operating modes - operating conditions, condition A, page 16).
The discrete input “Synch-check” is energized.
The synchronization time monitoring must be deactivated.

Control Outputs
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Synchronizing pulse:
close CB
Terminals 14/15
Through this relay, the CB receives the order to add-on. In normal operation,
the contact assembly in the synchronous point only closes for the configured
time of the add-on pulse. When in synchronizing control mode, a continuous
signal is output through this relay (see chapter "Control Inputs" on page 17).
If the CB has made contact and the unit gets this information through a corre-
sponding discrete input, this relay de-energizes.
Ready for operation
Terminals 18/19
The contact assembly is closed when the unit is ready for operation. The relay
will de-energize if the following occurs:
a) The internal self-monitoring system has detected an alarm condition.
Trouble-free operation of the unit cannot be guaranteed and appropriate
corrective measures must be taken.
b) The synchronization time monitoring system is enabled and the config-
ured time has expired before synchronization has occurred.
"Message:
Connect 2"
Terminal 16/17
For the description of these control inputs please refer to chapter "Relay Out-
put 16-17" on page 37
.
Three-position
controller speed
higher/lower
Terminals 8/9/10
Through these relays, pulses are output from the internal speed governor, in
order to adjust the frequency of system U2 to the frequency of system U1
(synchronization), or to adjust the frequency to the configured set point fre-
quency (no-load control). In order to obtain the speed variation required, the
relays have to be connected with the appropriate inputs of an external speed
governor. The order "lower" is output through the terminals 8/10, the order
"higher" is output through the terminals 8/9.
Three-position
controller voltage
higher/lower
Terminals 11/12/13
Through these relays, pulses are output from the internal speed governor, in
order to adjust the voltage of system U2 to the voltage of system U1 (syn-
chronization), or to adjust the voltage to the configured voltage set point (no-
load control). In order to obtain the voltage variation required, the relays have
to be connected with the appropriate inputs of an external voltage controller.
The order "lower" is output through the terminals 11/13, the order "higher"
through the terminals 11/12.
