GCU-3000 9
Note : 10 to 15 Vac open circuit is about the right
output voltage for a MPU measured directly into a
digital voltmeter with the engine running at rated speed
50 or 60 Hz.
Some Electronics Speed Controllers or Governors do
not allow sharing the MPU with other devices. If a MPU
is required for over-speed protection we recommend
an extra independent Magnetic Pick-up or a dual coil
(MPU) If the GCU is programmed to use an MPU, and
the MPU is defective or open or its, unable to read the
MPU, the system shutdown the engine and the MPU
signal failure icon appears on the screen.
For MPU related settings refer to chapter 3.15 System
Setting lines (1), (16), (17), (18), (19), (20), (44).
3.8 The Additional Inputs Alarm1 & Alarm2
The GCU is equipped with 2 spare inputs to add two
extra protections.
To set Alarm1 & Alarm2 go to chapter 3.15 System
Setting Lines (56), (57), (58), (59), (60), (61).
3.9 Setting the Service Reminder
The maintenance icon on the screen is a reminder to
the service personal that it is time to carry out
maintenance on the generator. When setting the
service timer, each unit entered is equal to 10hrs, for
example if entering 20 is equal to 20 x 10Hrs = 200
Hrs.
After completing maintenance, you need to clear the
record and set a future maintenance point. See System
Setting Line (68).
For Service & Maintenance related settings refer to
System Setting Lines (62), (68).
3.10 Screen Viewing
You can freeze the screen parameter or leave them to
cycling one by one. When cycling, each parameter
paused for 2 seconds, but pressing the (UP Arrow)
button, you can select either AC Voltage or AC Current
readings, also pressing the (Down Arrow) key permits
you to cycle though the phases, The Hour meter,
Battery Voltage, Hz, engine temperature measurement
in C or F and oil press measurement in Psi or Bar.
When using the (UP Arrow) and (Down Arrow) keys
to select specific parameters, the selected value
freezes for 30 seconds and if the system is left
unattended it automatically return to cycling.
For Panel related settings refer to chapter 3.15 Setting
Lines (63), (64), (65).
3.11 Engine Idle Operation Function
You can idle the generator automatically before
working at full load.
For Idle Operation related settings refer to chapter 3.15
System Setting Line (50).
3.12 Digital Temperature Sensor (Optional)
You can install the most accurate temperature sensor
available on the market. It greatly improves accuracy
from traditional thermal sensors.
Digital Temperature Sensor accuracy：-55 to +125 ˚C
+/- 2 ˚C
Temperature Display Unit：˚C or ˚F
3.13 Ceramic Capacitive Oil Pressure Sensor
(Optional)
The Ceramic Capacitive Oil Pressure Sensor is most
the most accurate oil pressure sensor available on the
market. It greatly improves the accuracy from
traditional oil pressure sensors.
Ceramic Capacitive Oil Pressure Sensor accuracy：0 to
120 Psi +/- 2.5%
Oil Pressure measurements in Psi or Bar
