Frequency
Display
Output Power Fell Below the Lo-P Limit.
If the output power is less than the set low-
limit value, the FREQUENCY display will show LO-P; an alarm will sound; the FAIL LED
will flash; and the VOLTAGE and CURRENT displays will show the corresponding value at
that time.
Frequency
Display
Output Power Factor Exceeded H-PF Limit.
If the output power factor exceeds the set
high-limit value, the FREQUENCY display will show H-PF; an alarm will sound; the FAIL
LED will flash; and the VOLTAGE and CURRENT displays will show the corresponding
value at that time.
Frequency
Display
Output Power Factor Fell Below the L-PF Limit.
If the output power factor is less than
the set low-limit value, the FREQUENCY display will show L-PF; an alarm will sound; the
FAIL LED will flash; and the VOLTAGE and CURRENT display will show the corresponding
value at that time.
Frequency
Display
Inverter Power Supply Voltage Below Operating Range.
If the inverter power supply
voltage is less than 80% of the input voltage, the FREQUENCY display will show Lodc (Low
DC voltage). This means the INVERTER supply voltage is less than the normal working range
for the APS-1000P. An alarm will sound; the FAIL LED will flash; the PROTECT LED will
light; and the VOLTAGE and CURRENT displays will show their corresponding values.
Frequency
Display
Inverter Power Supply Voltage Exceeded Operating Range.
If the inverter power
supply voltage is greater than 120% of the input voltage, the FREQUENCY display will show
HIdc (Hi DC voltage). This means the INVERTER supply voltage is greater than the normal
working range for the APS-1000P. An alarm will sound; the FAIL LED will flash; the PROTECT
LED will light; and the VOLTAGE and CURRENT displays will show their corresponding
values.
