Figure 6 shows the keypad and LCD. Below the LCD display are three LED indicators marked CHARGE,
INTERRUPT, AND UNLOCKED.
The yellow CHARGE LED lights when power is applied to the AC+/- pins on any one of the 6 pin circular
connectors (A, B (portable-only), or C (portable-only)) on the side of the unit (see Figure 10) using one of the SPI1
charge cables, or another suitably configured connection.
The green INTERRUPT LED will light when the rectifier circuit is being interrupted, i.e. no current flowing.
The orange UNLOCKED LED will light when the unit does not have a valid GPS time lock thus not allowing
synchronized interruption. The UNLOCKED LED will initially light when the unit is turned on and remain on until
enough satellites have been acquired to obtain a time lock. This initial satellite lock may take up to 13 minutes
when the unit is in good satellite coverage. If the unit has been listening to the GPS datastream within the prior two
week period, then the lock time will be substantially less than this. The LED will also light if GPS acquisition is lost
for over 5 minutes during an interruption cycle. Interruption is always disabled if the UNLOCKED light is lit. An
interruption cycle that has been interrupted by loss of GPS lock will auto-resume upon re-acquisition of the GPS
signal.
