(3) Operation panel I/O terminal monitor (Pr. 52)
When Pr.52 = "55," statuses of the output terminals and FL remote communication virtual terminals (FU, ALM signal) are
monitored on the operation panel.
The I/O terminal monitor is displayed on the third monitor.
The LEDs are ON when a signal is input to terminal Y0 and when the signals FU and ALM are input. The LEDs are OFF
when no signal is input to terminal Y0 nor the signals FU and ALM. The center line of the LED is always ON.
ALM Y0
(4) Cumulative power/cumulative power 2 monitor and clear (Pr. 170)
Monitored values are accumulated in the cumulative power monitor (Pr.52 = "25") or in the cumulative power monitor 2
(dedicated to FL remote communication), and the displayed values are updated every hour.
The operation panel and FL remote communication display increments and display ranges are as indicated below.
Operation Panel ∗1
Range
0 to 99.99kWh
100.0 to 999.9kWh
1000 to 9999kWh
∗1
Power is measured in the range of 0 to 9999.99kWh, and displayed in 4 digits.
When the monitor value exceeds "99.99", a carry occurs, e.g. "100.0", so the value is displayed in 0.1kWh increments.
Writing "0" in Pr.170 clears the cumulative power monitor and the cumulative power 2 monitor.
REMARKS
If "0" is written to Pr. 170 and Pr. 170 is read again, "9999" or "10" is displayed.
(5) Cumulative energization time and actual operation time monitor (Pr. 171, Pr. 563, Pr. 564)
Cumulative energization time monitor (Pr. 52 = "20") accumulates energization time from shipment of the inverter every
one hour.
On the actual operation time monitor (Pr. 52 = "23"), the inverter running time is added up every hour. (Time is not added
up during a stop.)
If the monitored value exceeds 65535, it is added up from 0. You can check the numbers of cumulative energization time
monitor exceeded 65535h with Pr. 563 and the numbers of actual operation time monitor exceeded 65535h with Pr. 564.
Writing "0" to Pr. 171 clears the cumulative power monitor. (The cumulative time monitor can not be cleared.)
REMARKS
The cumulative energization time does not increase if the power is ON for less than an hour.
The actual operation time does not increase if the cumulative running time during power-ON status is less than an hour.
If "0" is written to Pr. 171 and Pr. 171 is read again, "9999" is always displayed. Setting "9999" does not clear the actual operation
time meter.
