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.
