Indicates a malfunction in the primary power circuit. If this code
appears on the display, contact the nearest Factory Authorized
Service Agent.
Indicates the left side thermal protection circuitry is
malfunctioning. If this code appears on the display, contact the
nearest Factory Authorized Service Agent.
Indicates left side of unit has overheated. Unit has shutdown to
allow fans to lower left side temperature. Operation will continue
after unit is within normal temperature range.
Indicates the right side thermal protection circuitry is
malfunctioning. If this code appears on the display, contact the
nearest Factory Authorized Service Agent.
Indicates right side of unit has overheated. Unit has shutdown
to allow fans to lower right side temperature. Operation will
continue after unit is within normal temperature range.
Indicates operation at maximum input current. The unit has
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 automatically
reduces output power to continue operation. If this display is
shown, have a qualified electrician check the input voltage.
Indicates secondary power circuit is malfunctioning. If this code
appears on the display, contact the nearest Factory Authorized
Service Agent.
Indicates the power on precharge cycle did not complete. If this
code appears on the display, contact the nearest Factory
Authorized Service Agent.
System cannot measure output voltage. If this code appears on
the display, contact the nearest Factory Authorized Service
Agent.
Indicates thermal protection circuitry on the Process Control
board is malfunctioning. If this code appears on the display,
contact the nearest Factory Authorized Service Agent.
Indicates PC2 has overheated. Unit has shutdown to allow fans
to lower temperature. Operation will continue after unit is within
normal temperature range.
Indicates thermal protection circuitry on the System Power
board is malfunctioning. If this code appears on the display,
contact the nearest Factory Authorized Service Agent.
Indicates PC3 has overheated. Unit has shutdown to allow fans
to lower temperature. Operation will continue after unit is within
normal temperature range.
