HYSTERESIS VALUE
0
to
59999
The hysteresis value is added to (for tYPE = LO-ACt), or subtracted from (for
tYPE
= HI-ACt), the setpoint value to determine at what value to deactivate the
associated setpoint output. Hysteresis is only available for Rate assigned
setpoints.
ON TIME DELAY
0.00
to
599.99
seconds
This is the amount of time the assigned Rate display must meet the setpoint
activation requirements (below setpoint for Low Acting and above setpoint for
High Acting), before the setpoint output activates. If the Rate Setpoint Action is
Timed-Out, this is the amount of time the output is OFF during the ON/OFF
output cycling. This parameter is only available for Rate assigned setpoints.
OFF TIME DELAY
0.00
to
599.99
seconds
This is the amount of time the assigned Rate display must meet the setpoint
deactivation requirements (below hysteresis for High Acting and above
hysteresis for Low Acting), before the setpoint output deactivates. This
parameter is only available for Rate assigned setpoints.
OUTPUT TIME-OUT
0.00
to
599.99
seconds
If the setpoint action is Timed Out and the setpoint is assigned to Counter,
then this is the amount of time the output will activate once the count value
equals the setpoint value. If the setpoint action is Timed Out and the setpoint is
assigned to Rate, then this is the amount of time the output is ON during the ON
/ OFF output cycling. If Rate Timed Output One-Shot mode is enabled, then this
is the time duration for the one-shot output pulse.
RATE TIMED OUTPUT ONE-SHOT
NO YES
If the setpoint action is Timed Out and the setpoint is assigned to Rate, select
YES
to have the output activate for a single pulse (one-shot) when the assigned
Rate display meets the setpoint activation requirements. Select NO for ON / OFF
output cycling per the “Setpoint (Alarm) Figures For Rate” diagram.
COUNTER AUTO RESET
NO
ZEr-St
CLd-St
ZEr-En
CLd-En
This automatically resets the display value of the Setpoint Assigned Counter
each time the setpoint value is reached. The automatic reset can occur at output
start or output end if the setpoint output action is programmed for timed output
mode. The counter may be reset to zero or the count load value. This reset may
be different from the counter reset action programmed in the Input Parameter
(INPUt) menu section.
SELECTION
ACTION
NO
No Auto Reset
ZEr-St
Reset to Zero at the Start of output activation
CLd-St
Reset to Count Load value at the Start of output activation
ZEr-En
Reset to Zero at the End of output activation
(timed out only)
CLd-En
Reset to Count Load at the End of output activation
(timed out only)
OUTPUT RESET WITH COUNTER RESET
NO
YESs
Selecting YES causes the Setpoint output to deactivate (reset) when the
Setpoint Assigned Counter is reset. The only exception is when the assigned
counter is reset by a setpoint generated counter auto reset.
OUTPUT RESET AT Sn+1
NO Sn-Str Sn-End
Selecting Sn-Str causes the setpoint output to deactivate (reset) when
setpoint Sn + 1 activates. (Example: S1 deactivates when S2 activates, and S4
when S1 activates.) The last setpoint will wrap around to the first.
Selecting Sn-End causes the setpoint output to deactivate (reset) when
setpoint Sn + 1 activates and then times out (deactivates). This selection only
applies if the Sn + 1 setpoint action is Timed Out. (Example: S1 deactivates
when S2 is activated and then times out.) The last setpoint will wrap around to
the first. This parameter is only available for Counter assigned setpoints.
