Read this entire manual and all other publications pertaining to the work to be performed before install-
ing, operating, or servicing this equipment. Practice all plant and safety instructions and precautions.
Failure to follow instructions can cause personal injury and/or property damage.
The engine, turbine, or other type of prime mover should be equipped with an overspeed (overtempera-
ture, or overpressure, where applicable) shutdown device(s), that operates totally independently of the
prime mover control device(s) to protect against runaway or damage to the engine, turbine, or other
type of prime mover with possible personal injury or loss of life should the mechanical-hydraulic gov-
ernor(s) or electric control(s), the actuator(s), fuel control(s), the driving mechanism(s), the linkage(s),
or the controlled device(s) fail.
CAUTION
To prevent damage to a control system that uses an alternator or battery-charging device, make sure
the charging device is turned off before disconnecting the battery from the system.
Electronic controls contain static-sensitive parts. Observe the following precautions to prevent dam-
age to these parts.
•Discharge body static before handling the control (with power to the control turned off, contact a
grounded surface and maintain contact while handling the control).
•Avoid all plastic, vinyl, and Styrofoam (except antistatic versions) around printed circuit boards.
•Do not touch the components or conductors on a printed circuit board with your hands or with
conductive devices.

Intended Use This control is intended to be operated according to the guidelines 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 control fitted with all available options. Inputs/outputs, func-
tions, configuration screens and other details described, which do not exist on your control may be ig-
nored.
The present manual has been prepared to enable the installation and commissioning of the control.
Due to the large variety of parameter settings, it is not possible to cover every combination. The man-
ual is therefore only a guide. In case of incorrect entries or a total loss of functions, the default settings
can be taken from the list of parameters located in the appendix of the Configuration manual.

Figure 1-2: Typical application of a mobile system
Mobile systems are defined as a generator set with a generator circuit breaker (GCB), which can easily be in-
stalled near a feeder or transformer, and operate as follows:
• In parallel with mains operation to support the utility [peak load operation]
• In automatic mains failure mode to operate in case of a mains failure [emergency operation]
• Independent operation from the utility [isolated operation]
• With a behavior which allows to open and close the interchange point to the utility [transfer operation]
The GCP-31/RPQ+SC08 supports these modes, which are required for a mobile system.
For maintenance on a interchange point to mains (high voltage transformer or wiring replacement), the GCP-
31/RPQ+SC08 requires the connection to the SYNCON Panel which helps the operator to overtake load from
mains to the mobile system and back. Therefore one or several mobile container(s) can be used.
The GCP-31/RPQ+SC08 offers a special discrete input for the transfer operation and emergency operation. Ad-
ditionally, it offers a special discrete input for connecting an phase rotation relay, which is required for the bus-
bar connection. The other modes are realized through special handling of the given control inputs.

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 char-
ges as easily as synthetics.
3. Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoam cups, cigarette packages, cello-
phane wrappers, vinyl books or folders, plastic bottles, etc.) away from the control, modules, and work
area as much as possible.
4. Opening the control cover may void the unit warranty.
Do not remove the printed circuit board (PCB) from the control cabinet unless absolutely necessary. If
you must remove the PCB from the control cabinet, follow these precautions:
•Ensure that the device is completely voltage-free (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 cabinet, place it in the
antistatic protective bag.
CAUTION
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.

Switch Position OFF
The GCP will be de-energized in this operating mode. No actions are initiated by the unit anymore. If you switch
to position OFF while the genset is running, the GCB opens and the genset stops immediately (it is assumed that
this is provided by the customer).
Switch Position Isolated Operation
The GCP operating modes are enabled:
STOP: Genset stops with cool down or remains stopped. If necessary, the load will be taken off of the
genset and the GCB will be opened.
MANUAL: Genset may be started and stopped manually. The generator breaker may be closed and opened
using the manual keys. Frequency and voltage are controlled isochronous.
AUTOMATIC: The genset will be started and the GCB will be closed if remote control has been activated.
TEST: The genset will be started. The GCB may be closed and opened using the MANUAL keys.
The set points for frequency and voltage may either be modified using the arrow keys at the unit or via the digital
inputs.
Switch Position Transfer Operation
(Function enable station and return to the mains)
The GCP operating modes may be freely available or fixed to MANUAL operating mode. The parameter "Inter-
change mode in Manual", which is responsible for this, is in the parameter group Automatic (refer to Configura-
tion Manual 37278).
The following is valid in general:
Only the GCB will be synchronized. It is not possible to connect to a de-energized generator busbar.
If the GCB is closed, the generator monitoring is loaded with the trigger times mains monitoring, the phase shift
monitoring is not active.
The automatic mains connection detection*) will be activated.
If no mains connection is detected, a frequency and voltage control with droop will be performed.
If a mains connection is detected, real and reactive power control will be performed.
A phase relation zero control with the mains may be restarted via the DI at terminal 53 (Enable MCB) or the
SYNCON Panel. This will be disabled automatically if a mains connection is detected.
It is principally possible to open the GCB with the Operation mode STOP key for security reasons.
*) Automatic mains connection detection:
The GCP detects automatically via phase L1 whether the generator is in parallel with the mains.
If the phase relation between mains and generator busbar is recognized as "fixed", the message "Mains con-
nected" will be displayed. This is the case if the angle of L1 between mains and busbar remains below a certain
angle limit for a certain time. Angle and time may be configured with the parameter "Detection mains coupling"
under phase controller within the parameter group breaker (refer to Configuration Manual 37278).
This automatic detection is used to decide whether real and reactive power or frequency and voltage control is to
be performed.

The following is valid for free operating mode selection at the GCP:
STOP: Genset stops with cool down or remains stopped. If necessary, the load will be taken off of the
genset and the GCB will be opened.
MANUAL: Genset may be started and stopped manually. The generator breaker may be closed and opened
using the manual keys.
AUTOMATIC: The genset will be started and the GCB will be closed if remote control has been activated.
TEST: Not possible; if transfer operation is selected during TEST operation, an automatic change to
MANUAL operating mode will be performed.
The set points for frequency and voltage or real power and power factor may either be modified using the arrow
keys at the unit, via the digital inputs, or using the SYNCON Panel.
Only the set points, the control of which is currently active, may be modified via the Dis.
Switch Position Peak Load Operation "Internal"
The GCP operating modes are enabled:
STOP: Genset stops with cool down or remains stopped. If necessary, the load will be taken off of the
genset and the GCB will be opened.
MANUAL: Genset may be started and stopped manually.
The generator breaker may be closed and opened using the manual keys. After closing the
GCB, real and reactive power are controlled.
AUTOMATIC: The genset will be started and the GCB will be synchronized if remote control has been acti-
vated. After closing the GCB, real and reactive power are controlled. The set real power 1 and
the power factor are stored "internally".
TEST: The genset will be started. The generator breaker may be closed and opened using the manual
keys.
The set points for real power and power factor may either be modified using the arrow keys at the unit or via the
digital inputs.
Switch Position Peak Load Operation "External"
The functions correspond with the switch position peak load operation "internal" except the difference that the
real power set point is controlled by a 0/4 to 20mA signal or transmitted via an interface.

Manual 37187A SYNCONpanel - Transportable Remote Synchronizing Panel
Switch Position Emergency Power Start
The GCP operating modes are enabled:
STOP: Genset stops with cool down or remains stopped. If necessary, the load will be taken off of the
genset and the GCB will be opened.
MANUAL: Genset may be started and stopped manually.
The generator breaker may be closed and opened using the manual keys.
No automatic change-over to emergency power is activated.
AUTOMATIC: If mains fail (measurement via terminals 50, 51, 52) the genset will be started, the MCB will be
opened and the GCB will be closed. If mains return, the MCB will be synchronized back after
the mains settling time has expired. Then the load will be taken off of the genset and the genset
will be stopped.
TEST: The genset will be started. The generator breaker may be closed and opened using the manual
keys. An automatic change-over to emergency power will be performed if necessary.
The set points for frequency and voltage may either be modified using the arrow keys at the unit or via the digital
inputs.
NOTE
It is required for the emergency power start function that the MCB reply is connected. The start and
stop commands from the GCP must also be wired to the MCB to enable an automatic change-over.

Remote ......The busbar voltage is measured via the industrial plug-in
connector. The measuring inputs on the front of the
SYNCONpanel (Busbar L1 and Neutral N) are discon-
nected.
CAUTION
Observe the safety instructions in the SYNCONpanel cover!
Measuring Inputs
18 Current
Current measuring input
The clamp-on transducer must be connected here.
NOTE
If no clamp-on transducer is used, the current measuring input must be closed with a short-circuiting
termination to ensure a proper operation of the unit without a clamp-on transducer.
19 Voltage
Voltage measuring input
The voltage measuring lines must be connected here.

Configuration
NOTE
When using the SYNCONpanel together with the GCP-31/RPQ+SC08, it is not possible to configure and
control the GCP-31/RPQ+SC08 remotely using LeoPC1 via CAN connection. It is required to configure
the unit via LeoPC1 and a DPC connection.
CAUTION
Please note that configuration only should be done in a standstill of the system.

Controller Configuration
Frequency Controller
In case of transfer operation mode, the unit controls frequency and voltage with droop behavior.
For the transfer operation mode, a droop characteristic for the frequency controller is required, otherwise the gen-
erator set would not be able to maintain a stable active power being in parallel with the mains.
Freq.controller
droop 02.0%
Frequency controller droop 0 to 20 %
The internally set value for frequency will be reduced by the configured value,
when the nominal power of the generator is reached.
