Bolero Manual
Controls and Display
Your Bolero inverter has two straightforward indicators known as LED’s (light emitting diodes).
AC Status LED
This multicolor LED shows the status of the output as described below.
Color of LED
Flashing green
Inverter is in stand-by waiting for an AC load to be switched ON,
Steady green
Inverter is operating normally
Orange
This LED blinks orange just before the inverter switches back to stand-by or
if the load is too small. Use this information to adjust the standby level to
your load. (see section on standby adjustment)
Steady Red
AC-Output has shutdown due to an AC short circuit or the output has been
overloaded. Reduce load or check for faulty wiring.
Warning!
The inverter restarts automatically after 20 seconds.
Low DC/Overtemp LED
Steady Red
Low DC
. DC battery volts have dropped to an insufficient level, re charge batteries
or reduce load.
CAUTION:
Inverter will restart automatically once 12v (24v) has been re-
established.
Flashing Red
Over temperature. Inverter has shut down due to excessive internal temperature.
Reduce load or improve ventilation around the inverter.
CAUTION: Inverter will
restart automatically once the internal temperature has
been reduced to a safe level.
Load Sense Feature and Adjustment
Your Bolero inverter features a Standby circuit for automatic load sensing, which allows the inverter to remain in Standby when
no AC load is switched ON. Once an AC load is switched ON the inverter will immediately start. This feature conserves valuable
battery energy as the inverter only uses approx 10% of the normal power when in standby (flashing green). The amount of AC
power required to start the inverter can be adjusted; the procedure for this (adjusting the sensitivity) is outlined below.
When no AC load is present, the inverter should remain in standby (AC status LED flashing GREEN).
Adjusting load sensitivity:
Ensure battery voltage is as close to nominal as possible, That is, 12, 24v DC
1.
Turn all AC loads OFF, keeping the AC wiring connected. Some loads such as TV’s must be turned OFF at the
power point as they can still represent a small load to the inverter.
2.
Using a small screwdriver adjust the black plastic trim pot located to the right of the two LED’s below the power
point. Adjusting this pot clockwise will make the inverter less sensitive. Turning the pot all the way clockwise
will override the standby circuit and keep the inverter ON all the time, this could be used when you have a very small
load that must stay ON at all times. Turning the pot all the way counter clockwise will turn the inverter OFF.
