Parameter
Description
Where to find:
Stop SOC
Generator is turned off if battery SOC equals or
crosses this threshold limit; default 95% of battery
capacity.
DG Function
Voltage Based
If enabled, controls generator On or Off as per the
bus voltage threshold.
Start Voltage
Generator is turned On if bus voltage falls below this
threshold limit; default 47.0V.
Stop Voltage
Generator is turned Off if bus voltage rises above this
threshold limit; default 54.0V.
DG Control Drive 1

DG Control Drive 1
Map output PFC relay of DCIO card for generator
relay 2.
DG Feedback Input
Map isolated input of DCIO card for generator run
status sense.
If both SOC and Voltage based control are enabled, then generator will start if any start
condition is true and generator will be turned off both conditions are true.
INPUT / OUTPUT (I/O)
The following section describes the input/output functions available with a single DCIO and PFCIO board.
Also see I/O Board Mapping on page 77
Additional Input / Output boards can be connected to EC500 to provide additional input/output to monitor
and control external devices.
IDENTIFY AN I/O BOARD
Input / output boards are referenced by their serial numbers; EC500 supports 4 DCIO cards and 2 PFCIO cards
➢
To identify a particular I/O board
•
At the time of system installation, set different jumper settings on each DCIO and PFCIO boards.
•
On board controller sense digital inputs of these jumpers and provide a unique Node ID.
•
EC500 communicate with these boards and use their allocated Node IDs for further
communication.
•
Identification of boards occurs only at power on time.
ANALOG SYSTEM VALUES
The EC500 provides access to the following system analogue values.
Parameter
Description
Where to find:
Bus Voltage
Each card
’s
first channel is allocated for Bus voltage;
EC500 reads the Bus voltage from each card. The
card which provides the Bus voltage greater than or
equal to 30V determined that card and channel for
system Bus voltage.
