Woodward GCP-30 Series Configuration

Manual 37278B GCP-30 Series - Genset Control
Page 130/174 © Woodward
Starting Sequence
If the control is equipped with a three-position frequency controller, a continuous signal (time adjustable via
Parameter 304) is output prior to starting the engine at t
he "Frequency lower" relay output. Following the expira-
tion of this time, the "Pre-glow" relay will be enabled (pre-glow time is configurable via Parameter 299). Follow-
ing preheating, the fuel relay is enabled (Parameter 305), followed by the crank relay. Once the firing speed
(Parameter 308) has been exceeded, the starter disengages, and the fuel relay rem
ains enabled by means of the
firing speed. After reaching the "f-controller: starting frequency" (Parameter 50) and the delayed engine monitor-
i
ng has expired (Parameter 307), the speed controller is enabled.
Stopping Sequence
When the start request is terminated, a power reduction is performed (if the real power controller is enabled,
Parameter 87). Once the GCB has opened, an engi
ne cool down is performed (Parameter 306). When the engine
cool down period expires, the fuel relay is de-energized and the engine is stopped. If the engine speed falls below
the firing speed (Parameter 308), the engine starting sequence is disabl
ed for 10 seconds. If the engine cannot be
stopped, an alarm message is issued after 30 s, and a class F3 alarm is initiated.
Parameter
Parameter 299
Preglow time
00s
Diesel engine; pre-glow time 0 to 99 s
Prior to each starting sequence, the engine glow plugs are enabled for this time pe-
riod.
Parameter 300
Max. attempts to
Start 0
Diesel engine; maximum number of start attempts 1 to 6
The control will initiate up to this number of start attempts. If the engine cannot be
started within this number of start attempts, an alarm message is issued.
Parameter 301
Starter time
00s
Diesel engine; crank time 2 to 99 s
The maximum amount of time the starter will crank the engine during a start se-
quence.
Parameter 302
Start pause time
00s
Diesel engine; time between two start attempts 1 to 99 s
The delay time between the individual start attempts.
Parameter 303
f lower before
start OFF
with three-step controllers only
Diesel engine; approach low-idle position ON/OFF
If this function is enabled and the control is equipped with a three-step frequency
controller, the command "lower engine speed" is issued for the time configured in
Parameter 304 before the starter is engaged. The low-idle position m
ust either be
equipped with a limiting switch, or the engine potentiometer must be equipped with
a slipping clutch to protect the devices. A message is displayed.
CAUTION
The engine starting is delay by means of the low-idle position in the event of emer-
gency power operation.
