5.0 DIGITAL METER & MANUAL DISCONNECT
A digital meter is available with the ProStar controller as an option. If your version includes the
meter display, this section will describe the information that can be displayed with the meter, and
the added capabilities that are enabled by the push button switch.
5.1 DIGITAL METER
A precision 3-digit digital meter will continuously display battery voltage, solar current, and the
load current. The meter automatically scrolls through these 3 displays. The 3 red LEDs will
indicate which parameter is being displayed.
The digital meter will operate from –30°C to +85°C. The values displayed are calibrated
electronically in production and are accurate to within a few percent. Please note, however,
that if the Battery Sense is not connected, the voltage displayed will be in error by the voltage
drops in the battery wires.
5.2 MANUAL DISCONNECT
The push button next to the digital display can disconnect the Load or both Load and Solar.
A second push of the button will return the controller back to normal operation.
LOAD OFF:
A brief push of the button (less than 2 seconds) will disconnect the
Load. The Solar remains on and charging.
LOAD AND SOLAR OFF:
If the button is held down for 2 seconds, the Solar will
also be disconnected.
When the button is pushed, the red LED inside the cap will light. In addition, the Load or both
Load and Solar will display “OFF“ in the digital meter to indicate the disconnected state.
5.3 DISPLAY DISCONNECTS & PROTECTIONS
The following protection functions and disconnect conditions will be displayed in the digital
meter when they occur:
LUD
LVD – low voltage load disconnect (load only)
HUD
high voltage disconnect (both solar and load)
HOT
high temperature disconnect (both solar and load)
OCP
overcurrent and short circuit protection (load, solar overcurrent)
0.0
short circuit protection (solar only)
5.4 SELF-DIAGNOSTICS (SELF-TEST)
If the push button is held down for 4 seconds, the ProStar will go into automatic self-diagnostics.
Note that the button must be released to start the self-test.
