Description
"ON" OC is collecting operation da-
ta. A blinking display indicates that
data collection is temporarily sus-
pended. No switch setting is neces-
sary. Data collection will be
resumed automatically. See Sec-
tion [9-4-2 Troubleshooting]2-(1).
"OFF" Collection of operation data
is suspended.
"F-Er" Collection of operation data
is suspended due to failure in the
flash memory used to store opera-
tion data. It may be necessary to
change the board. See Section [9-
4-2 Troubleshooting]2-(2).
"Err" Error was found due to the fail-
ure in units. After addressing the

restated. See Section [9-4-2 Trou-
