For counting up, the OUT value is as follows:
●
OUT < TOTAL_SP - PRE_TRIP
OUT_TRIP = 0, COUT_PTRIP = 0
●
TOTAL_SP - PRE_TRIP <= OUT < TOTAL_SP
OUT_TRIP = 0, COUT_PTRIP = 1
●
TOTAL_SP <= OUT
OUT_TRIP = 1, COUT_PTRIP = 1
For counting down, the OUT value is as follows:
●
PRE_TRIP < OUT
OUT_TRIP = 0, COUT_PTRIP = 0
●
0 < OUT <= PRE_TRIP
OUT_TRIP = 0, COUT_PTRIP = 1
●
OUT <= 0
OUT_TRIP = 1, COUT_PTRIP = 1
Note that the given conditions do not apply to the following cases:
• If INTEG_TYPE is 5, 6, or 7, OUT_TRIP and OUT_PTRIP always output "0."
• If INTEG_TYPE is 1 or 3, occurrence of AutoRESET (reset caused if the threshold is exceeded) causes
OUT_TRIP to hold "1" for five seconds.

Integration calculation is stopped.
OUT will not be updated unless you
set a value to it. No reset is accepted.
You may rewrite a value in OUT. If no value is rewritten,
the value just before running in AUTO is held. When the
mode returns to AUTO, integration starts with the written
value or the value just before running in AUTO.
Out of Service (O/S)
If you rewrite the value in OUT and RTOTAL while the mode is in MAN or O/S, N_RESET is incremented.
A2.6 Reset
A2.6.1 Reset Trigger
There are the following five types of reset triggers:
1. An integrated value exceeds TOTAL_SP.
2. An integrated value falls below "0."
3. RESET_IN is "H."
4. Every period specified in CLOCK_PER (for more information, see CLOCK_PER in A2.6.2)
5. OP_CMD_INT is 1.
The table A2.2 shows the correlation between INTEG_TYPE and RESET triggers.
