When in the search sense mode, the green power LED will blink and the inverter will make a ticking sound. At full
output voltage, the green power LED will light steadily and the inverter will make a steady humming sound. When the
inverter is used as an "uninterruptible" power supply the search sense mode function should be defeated.
Exceptions:
Some devices when scanned by the load sensor cannot be detected. Small fluorescent lights are the most common
example. (Try altering the plug polarity by turning the plug over.) Some computers and sophisticated electronics have
power supplies that do not present a load until line voltage is available. When this occurs, each unit waits for the other
to begin. To drive these loads either a small companion load must be used to bring the inverter out of its search mode,
or the inverter may be programmed to remain at full output voltage.

3.6 Protections

The UP Series inverter is equipped with extensive protections against various harsh situations/faults.
These protections include:
AC Input over voltage protection/AC Input low voltage protection
Low battery alarm/High battery alarm
Over temperature protection/Over load protection
Short Circuit protection (1s after fault)
Back feeding protection
When Over temperature /Over load occur, after the fault is cleared, the master switch has to be reset to restart the
inverter. The inverter will go to over temp protection when the heat sinks temp. ≥105ºC (221℉), and will go to Fault
(shutdown Output) after 30 seconds. The switch has to be reset to activate the inverter. The UP Series Inverter is with
back feeding protection which avoids presenting an AC voltage on the AC input terminal in Invert mode. After the
reason for fault is cleared, the inverter has to be reset to start working.

3.7 Remote Control

Apart from the switch panel on the front of the inverter, an extra switch panel connected to the RJ11 port at the DC side
of the inverter through a standard telephone cable can also control the operation of the inverter. If an extra switch panel
is connected to the inverter via "remote control port", together with the panel on the inverter case, the two panels will be
connected and operated in parallel.
The Inverter can also be switch on/off through the "RMT SW" pin in the right of AC terminal.
They inverter will be powered on once a +12Vdc (acceptable range 10-16Vdc) source is connected to the PIN, and
powered off when the +12Vdc source is disconnected(if the switch panel is in "Unit off" position).
