Chapter 5. SETTING AND OPERATION
(2) When
C03
is set to
02
or
05
(instantaneous flow rate lower limit)
If the flow rate falls below the instantaneous flow rate lower limit, event out-
put turns on. The point at which event output turns off involves a hysteresis
and is calculated as follows:
Event OFF point = instantaneous flow rate lower limit + hysteresis
Specify the hysteresis as a percentage of the full scale flow rate (% FS).
(3) When C03 is set to 03 or 06 (within range for instantaneous flow rate)
When E1.SP > E2.SP , the setting for E1.SP is used as the upper limit and the
setting for E2.SP is used as the lower limit. When E1.SP < E2.SP , the E1.SP
setting is the lower limit and E2.SP setting is the upper limit.
When E1.SP = E2.SP , this function does not operate.
Hysteresis should be set below the lower limit and above the upper limit.
Specify hysteresis as a percentage of full scale flow rate (% FS). Different
hysteresis can be set for the lower limit and the upper limit.
•
E1.SP
setting <
E2.SP
setting
• E1.SP setting > E2.SP setting
Note: If Event OFF point is less than zero, the output turns off at zero.
*2: Event ON delay
The event ON delay sets a delay before the event output turns on.
E1.dLy
is for
the setup of
E1.SP
and
E2.dly
is for the setup of
E2.SP
.
*3: Flow rate cost calculation
The flow rate cost calculation is related to the setting for flow rate units in func-
tion setup
C02
.
