(e.g., blown fuse or circuit breaker tripped).
Change Float Voltage
The system arrives with a pre-defined float voltage. If it is necessary to change this
voltage setting, use the feature below.

Generator Setup
The generator interface is designed for systems supported by a diesel generator
that charges batteries and powers the system. Only BC2000 controllers with
controller software version 4.01.30 or higher and display version 7.01.24 or higher
support interface with a diesel generator (go to “Main Menu” and select “Version” to
check controller and display versions).
In order for the diesel generator and the BC2000 controller to interface properly,
three alarm connections are required:
1. The generator must be connected to the form-C output relay “F” (tan-colored
wire set) of the controller alarm cable; use Normally Open (“NO”) and Common
(“C”). See Table 2.
2. A status relay from the AC service panel must be connected to input “T3” on
the controller. This input port (“Probe 3”) should be set to “Auxiliary –
Normally Closed.”
3. A status relay from the diesel generator must be connected to input “T4” on
the controller (far right connector). This input port (“Probe 4”) should be set
to “Auxiliary – Normally Open.”
NOTE: To setup the input ports, refer to the section “Input Port Setup” on page 21.
