G SERIES USER MANUAL
6.0 ENERGY MANAGEMENT SYSTEM PROGRAMMING
Battery Status
Battery Status reports general battery state as well as actual battery voltage. When the Battery Status reads
Char
(charge), the voltage is lower than normally desirable, but the system will continue to operate normally.
When the Battery Status reads
Lo
(low), the system is in Low Voltage Disconnect (LVD). LVD is a safety
mechanism that the EMS invokes to prevent over-discharge of the battery. When in LVD, the fixtures will
not
flash
and the digital output signal (if used) is also turned off.
Solar Status
The Solar Status indicates whether the system has determined it is night or day based on the photosensor
located in the top of the body near the antenna. The second value that is displayed is the output voltage of the
solar panel and is useful for troubleshooting. Solar panel voltage in sunlight will typically be between 15 and 20
volts.
In addition to fixtures not being connected properly, the EMS may also display the
Led oPEn
fault message when:
•
a fixture with too high an operating voltage is connected
•
a very long LED harness is combined with a high intensity setting
•
a single LED sign or beacon is used with an alternating flash pattern
LED Fault alert (exceptions):
•
will not detect a disconnected fixture when more than one beacon/sign or any number of
light bars are installed with a unison flash pattern
•
will not detect a disconnected fixture when more than one lightbar or more than two
beacons/signs are installed
•
may not detect a fixture short circuit or disconnection when a rapid or quick flash pattern
is used. Temporarily changing to flash pattern 0.5A can assist in troubleshooting.
