3.11 Digital outputs
Category
Specifications
Controller terminals
3, 4, 5, 6, 7, 8, 9
Number of outputs
7
Type
DC outputs
Maximum current rating
5 A (3 and 4)
1 A (5, 6, 7, 8, 9)
Software configurable options
Start relay, Fuel relay, Close genset contactor, Stop solenoid and many more
(see
Controller overview, Configurable parameters
in the
User manual
for
more details).
NOTE
•
Do not connect the Starter motor relay and the Stop solenoid directly to the controller's output terminals. It is
recommended to connect terminals 3 and 4 to Start and Stop.
•
Genset contactor latching relays should be compiled against 4 kVA surge as per IEC-61000-4-5 standard.
3.12 D+ Charger alternator
Category
Specifications
Controller terminal
10
Voltage range
0 to V
BATT
V
BATT
= 8 to 32 V DC
Excitation
PWM (power limited to 3 W, 12 V/250 mA, 24 V/125 mA)
Accuracy
±2 % of full scale
The charge fail is a combined input and output terminal. When the genset starts, the terminal provides controlled power output to
excite the charging alternator. After the excitation is successfully done, the controller reads the charging alternator's output voltage
for monitoring its health. The action for charge fail is configurable.
3.13 Sensor common point
Category
Specifications
Controller terminal
16
Range
±2 V
Accuracy
±2 % of full scale
The sensor common point (SCP) terminal 16 must be connected directly to an electrically sound point on the engine body. This point
serves as a common reference point for all analogue sensors. The electrical cable used for the connection must not be shared with
any other electrical connection. This wiring practice is strongly recommended to ensure that there is negligible potential difference
between the engine body and the controller's SCP terminal, and that predictable and accurate analogue sensor measurements are
always available in a wide variety of field conditions.
