Status and Charging LED
The Status and Charging LED (light emitting diode) are located on the front panel of the 8310-N
and on the left side of the 8310-O. The Status LED consists of two LED – one green and the
other red. The green LED will flash periodically to indicate activity by the system. The red LED
only lights when there are errors present that should be viewed and cleared by the user.
The Charging LED is green when the built-in solar panel regulator is charging the battery. The
LED will be off if the voltage from the solar panel is less than the battery voltage.
Terminal Strips
Terminal strips are used to connect sensors, power, and some communication to the 8310.
There are two basic configurations for terminal strips depending on the model ordered:
8310-N --The terminal strips are built in to the side of the fiberglass enclosure.
8310-O -- The terminal strips are built into the front of the unit.
Connections to the terminal strip are made as follows:
Strip approximately 1/8th inch of insulation from the end of a signal or ground wire
Loosen the appropriate terminal block screw
Insert the stripped portion of the wire into the small, rectangular opening immediately
beneath the screw
Re-tighten the screw.
After all connections are made to an 8310, the connectors may be unplugged from the unit with
all wiring intact. To remove a connector, grasp each end firmly and pull/wiggle until it comes
free. The removable connectors make it possible to completely replace an 8310 in a matter of
minutes.
Each terminal strip is labeled with a letter, A, B, C and D. The following sections give details on
the different connections:
