8. Remote Battery Voltage Sense
The MPT-3024 features remote battery voltage sense capability, whereby the
terminal voltage of the battery bank is monitored directly at the batteries using
a dedicated pair of low-current wires. The conventional method of measuring
battery voltage typically relies upon wires which often carry a significant amount
of current. High currents introduce a voltage drop in the wires, causing an
error in the actual voltage as measured by the controller. Using a separate pair
of low-current wires to measure the voltage eliminates this error.
9. Auxiliary Output / Relay
The MPT-3024 offers an auxiliary output that can be used to turn on external
devices (a vent fan, for example) when the battery voltage meets a predeter-
mined setpoint (as adjusted by the user). When the battery voltage falls below
this setpoint, the output turns off. For greatest flexibility, the output is actually
a two-terminal circuit that is opened and closed by a relay.
10. RE-CONN Communication Port
A RS-485 communication port is standard on the MPT-3024. It uses a
proprietary (“RE-CONN”) protocol developed by Rogue. The port may be
interfaced with a PC running Rogue’s RE-CONN software via an optional
DCV-0001 RS-232 data converter. It may also be connected directly to remote
monitoring devices that may be available from Rogue. Power is available via the
RE-CONN port for devices that may require an external source.
!
The RE-CONN communication port is not Ethernet compatible.
Connecting an Ethernet device to the port may result in damage to the
device or the controller.
!
Use only devices with the RE-CONN port that are supplied by or
authorized by Rogue. Using other devices may damage the controller.
