STATUS
When you turn on the WM1400 with a keypad installed, the keypad screen will be displayed.
Press NEXT DISPLAY twice.
The inverter STATUS will be displayed. The inverter can have one of three status conditions. When
first turned on it will show STANDBY mode.
When this screen is displayed, the Status can be changed by pressing the UP or DOWN arrow keys.
Each time the UP key is pressed, the status will change from STANDBY to CONT to RESET and
back to STANDBY where the DOWN key will change the Status in the reverse order.
The second line indicates if the inverter is ON or OFF. When ON the inverter is supplying 240V mains
power. During standby, OFF is displayed on the second line, reverting to ON when a load is sensed
and the inverter starts.
STANDBY mode means that the WM1400 is producing pulses of power to sense when an
appliance is switched on. This is called the demand start because as soon as the appliance is
switched on, the WM1400 will turn on and provide full power to the appliance.
The inverter will drop back into standby mode once all loads have been switched off for longer than
10 seconds. After this time, the WM1400 will return to pulsing or demand start mode waiting for
another load to turn on.
This feature is extremely important as it conserves valuable battery power when no appliances are on.
The amount of power or load that the Inverter needs to “start up” is adjustable, see page 5 for details.
CONT mode (CONTINUOUS) means that the Inverter will be on at all times regardless of whether
appliances are connected or not. This situation is useful if you have small loads such as a VCR or
digital clock that requires 24 hour power, or if loads are too small to be sensed in the STANDBY
mode. The only disadvantage is that when the appliances are off the WM1400 will be drawing more
power than it would in STANDBY mode.
RESET mode electronically shuts down the inverter. When placed in this mode, any overload or
shutdown conditions are also reset. This situation will be explained in more detail in a later section.

This reading gives an indication of the AC voltage produced by the
inverter. This reading will vary depending on how large a load is connected
or if the battery voltage is very low. Pressing the AC LOAD READINGS
button again will move you to the next “AC Amps” screen.
