Help 3 Display
Indicates the left side of the unit has
overheated. The unit has shut down
to allow the fan to cool it (see Section
3-4). Operation will continue when
the unit has cooled.
Help 5 Display
Indicates the right side of the unit has
overheated. The unit has shut down
to allow the fan to cool it (see Section
3-4). Operation will continue when
the unit has cooled.
Help 6 Display
Indicates operation at maximum in-
put current. The unit has a maximum
allowable input current limit. As the
line voltage decreases, the required
input current increases. If the line
voltage is too low, the output power
is limited by the input current. When
this limit is reached, the unit automat-
ically reduces output power to con-
tinue operation. If this display is
shown, have a qualified electrician
check the input voltage.
Help 8 Display
Indicates a malfunction in the sec-
ondary power circuit of the unit. If this
display is shown, contact a Factory
Authorized Service Agent.
