NOTE:
The output is
now under the
direct control
of the operator
and can be adjusted
in the run mode,
by pressing the
MAX and MIN buttons.
The control value
(0 - 99), now
display in the
SV window indicate,
approximately
in percent, the
output. For example,
a setting of
0050 of an analog
output of 0~10Vdc
would produce
roughly 5Vdc
at the output.
Also, to insure
smooth transition
when switching
to self mode,
the proportional
control output
is left in its
last value, when
self mode is
activated for
the first time.

MINIMUM/PERCENT
LOW SUBMENU
Specify in percent,
the minimum value
(0000) for control
output. If the
output is analog,
then the minimum
voltage or current,
in percent, is
specified. If
the output is
time proportional,
then the minimum
duty-cycle, in
percent, is specified |

MAXIMUM/PERCENT
HIGH SUBMENU:
Specify in percent,
the maximum value
( 0099 ) for
control output.
If the output
is analog, then
the maximum voltage
or current, in
percent, is specified.
If the output
is time proportional,
then the maximum
duty-cycle, in
percent, is specified. |

12) Press
ENTER to store
the current setting
and to advance
to *Control Type
submenu. |
| Example:
On an analog
output of 0~10Vdc,
a setting of
%LO = 10 and
%HI = 90, cause
the minimum on
the control output
to be 1V and
the maximum on
the control output
to 9V. The same
setting on a
time proportional
output, will
cause 10% duty
cycle for the
minimum control
output and 90%
duty cycle for
maximum control
output. To disable
%LO/HI, set LO
to 00 and HI
to 99. If %LO/HI
is at other values
than the default
(%LO=00, %HI=99),
ôsoakö is disabled. |

15)
Display flashes
"strd" message
and advances
to "Action Type"
submenu. |
Note: The ON/OFF
control is a coarse
way of controlling
the process. The "Dead
Band" improves the
cycling associated
with the On/Off control.
The PID control
is best for processes
where the set point
is continuously changing
and/or a tight control
of the process variable
is required. PID control
requires tuning and
adjustment of the "Proportional",
"Integral or Reset"
and "Derivative or
Rate" terms by a trial-and-error
method. The Controller
provides an "Auto Tuning"
feature making the
tuning process automatic,
possibly optimum.

Select "Enbl"
for a 4-20mA
output or "dsbl"

|
Note: The error
that results from the
measurement of the
process variable may
be positive or negative
since it may be greater
or smaller than the
set point. If a positive
error should cause
the controller output
to increase (i.e. cooling),
it would be called
Direct Acting.
If a negative error
should cause the output
to decrease (i.e. heating),
it would be called
Reverse Acting.

the controller
is ready to calculate
P, PI or PID
parameters. The
set points must
be at least 20░F
or 11░C above
the (PV) process
value in order
to perform autotune,
otherwise an
error message
will be displayed. |
Note:To start auto
PlD select PID, enable
Auto PID and enable
Start PID. Sometimes
Auto PID parameter
needs fine tuning i.e.
for each 5░F over shoot
increase the Proportional
Band (PB) by 15% and
for each ▒1░F fluctuation
at the Set Point (SP)
increase reset by 20%.
Once started, do
not perform any operations

first stopping auto-tune.
Any alarms or other
output is disabled
during auto-tune.

a 15 second cycle time
means that every 15
seconds the output
will turn on for part
or all of the cycle.
For Relay control outputs,
do not select a cycle
time of less than 7
seconds or the relays
life time will be shortened.
For a cycle time of

is a measure of speed,

variable responds to
the output changes
of the controller,
which were used during
the Auto Tune. This
value is typically
set to the ratio of
Rate to Reset. This
Default value is (0004).
For fast response time,
this value should be
decreased while for
slow response time
it should be increased.
