value when out
of range (SLH...
SHH)
Logs the Max/Min value recorded by Pb3
when it exceeds range SLH...SHH.
“n” represents the sequential number of
times the range is exceeded.
• Recording of folder “HC n” in folder AL
• Alarm LED steady
• No effect on regulation
NB: “n” can assume the values 1 to 8.
If n > 8, folder HC8 will flash and the
system will overwrite folders where n=1
tC n
Pb3 out-of-range
dwell time
(SLH...SHH)
Stores the dwell time of the Pb3 value outside
range SLH...SHH. n” represents the sequential
number of times the range is exceeded.
• Recording of folder “tC n” in folder AL
• Alarm LED steady
• No effect on regulation

If n > 8, folder HC8 will flash and the

Logs the value recorded by Pb3 on return
from a blackout. “n” represents the sequential
number of blackouts that have occurred.
• Recording of folder “bC n” in folder AL
• No effect on regulation

If n > 8, folder bC8 will flash and the
system will overwrite folders where n=1
bt n
Pb3 out-of-range
dwell time
during bOt
Stores the out-of-range dwell time of the
Pb3 value during a blackout.
“n” represents the sequential number of
blackouts that have occurred.
• Recording of folder “bt n” in folder AL.
The value contained will be 0 if the value of
Pb3 has remained within the range, ≠ 0 if the
value has gone outside of the range
• No effect on regulation
N.B.: “n” can assume the values
1 to 8.
If n > 8, folder bC8 will flash and
the system will overwrite folders
where n=1
NOTE: to delete folders “HC n”, “tC n”, “bC n” and “bt n” from folder AL, start function rES in folder FnC.
