NOTE:
The battery should be connected first. This will activate the controller
protection features, and will power the LEDs to guide installation and
start-up.
STEP 3: Battery
Before connecting the battery, measure the battery’s open-circuit voltage. It must be
over 8 volts to operate the controller. For 24 volt systems, the battery must be over
15.5 volts or the ProStar will regulate for 12V. The 12/24V auto selection is only done
at start-up.
Connect the battery and confirm that the 3 Battery Status LEDs blink in sequence. If
they do not light, check the battery polarity (+/–) and battery voltage.
CAUTION:
The ProStar is protected against all faults EXCEPT a reversed battery
connection together with a polarized or short circuited load. CON-
FIRM that the b and – wires are correctly connected before
proceeding. Check the wires and the LEDs.
The green, yellow or red LED will light depending on the battery charge state.
Confirm one of these LEDs is on before going to the next step.
STEP 4: Sense
Battery sense connections are recommended if the controller is more than 5 meters
from the battery. The Sense, connected directly to the battery, will improve the
battery charging and control.
Both Sense wires (+/–) must be connected. A small wire size (18 AWG or larger) can
be used for the Sense because the current is very low. Note that the middle 2
terminals are for sense (with the smaller wire slots in the case).
NOTE:
If the Battery input voltage is more than 5 volts different than the Sense
due to voltage drops or faulty connections, the Sense input will not be
recognized by the ProStar.
STEP 5: Solar
These terminals are used to connect the Solar (PV) array. First confirm that the solar
modules are wired for the same voltage as the battery.
Use caution, since the solar array will produce power whenever in sunlight. If the
solar is connected while in sunlight, the Charging LED indicator will light. Confirm
proper connection with the Charging LED.
STEP 6: Load
Turn the load off, and connect the load wires to the Load terminals. Turn the load on
to confirm a proper connection.
If the load does not turn on, it could be for various reasons:
• the ProStar is in LVD (red LED on)
• there is a short circuit in the load (LEDs blinking R/G – Y)
• there is an overload condition (LEDs blinking R/G – Y)
• the load is not connected, not working, or turned off
Confirm the load is working properly before going to Step 7.
