LCD Display
Description
Over Load
Displayed when a motor is overloaded. Set PRT-17 to ‗1‘ to enable.
Set OUT-31–35 or OUT-36 to ‗5 (Over Load)‘ to receive the overload
warning output signals.
Under Load
Displayed when the motor is underloaded. Set PRT-25 is to ‗1‘. Set
the digital output terminal or relay (OUT-31–35 or OUT-36) to‘ 7
(Under Load)‘ to receive the underload warning output signals.
INV Over Load
Displayed when the overload time equivalent to 60% of the inverter
overheat protection (inverter IOLT) level, is accumulated. Set the
digital output terminals or relay (OUT-31–35 or OUT-36) to ‗6 (IOL)‘
to receive the inverter overload warning output signals.
Lost Command
Lost command warning alarm occurs even with PRT-12 set to ‗0‘.
The warning alarm occurs based on the condition set at PRT-13-15.
Set the digital output terminals or relay (OUT-31–35 or OUT-36) to
‗13 (Lost Command)‘ to receive the lost command warning output
signals.
Fan Warning
Displayed when an error is detected from the cooling fan while PRT-
79 is set to‘1‘. Set the digital output terminals or relay (OUT-31–35 or
OUT-36) to ‗8 (Fan Warning)‘ to receive the fan warning output
signals.
DB Warn %ED
Displayed when the DB resistor usage rate exceeds the set value.
Set the detection level at PRT-66.
Fire Mode
When there is a fire, Fire Mode forces the inverter to ignore certain
fault trips and continue to operate. Set the digital output terminals or
relay (OUT-31–35 or OUT-36) to ‗27 (Fire Mode)‘ to receive the fire
mode warning output signals.
Pipe Broken
Displayed when a pipe is broken during pump operation. Set the
digital output terminals or relay (OUT-31–35 or OUT-36) to ‗28 (Pipe
Broken)‘ to receive the pipe break warning output signals.
Lost Keypad
Displayed when a communication error occurs between the keypad
and the inverter, when PRT-11 (Lost KPD Mode) is set to any other
value than ‗0‘, and a run command is given from the keypad. Set the
digital output terminals or relay (OUT-31–35 or OUT-36) to ‗24 (Lost
KPD)‘ to receive the lost keypad warning output signals.
Level Detect
Displayed during a level detect state. Set PRT-70 to ‗1 (warning)‘ to
enable.
CAP. Warning
Displayed when capacitor life expectancy level goes below the level
set by the user. Set the digital output terminals or relay (OUT-31–35
or OUT-36) to ‗34 (CAPWarning)‘ to receive the capacitor life
warning output signals.
Fan ExChange
Displayed when the cooling fans need replacing. Set the digital
