1. To enter SET POINT
Temperature (lower Display)
A. To enter set point
temperature ( Temperature at which process is to be controlled), Press the SHIFT KEY <,
the first digit will begin blinking.
B. Press the UP KEY ^
or the DOWN KEY to increase or decrease the value of the digit (*) then press the
SHIFT
KEY again to go to the next digit. After all digits are changed the display should read
the desired set
point temperature i.e. 1251 for 1,251 degrees or 0400 for 400 degrees etc.
C. If the display for
set point temperature is correct press SET KEY to enter the value.
*
If the up/down keys are held
down, the display will scroll continuously from the least significant
digit (the one that
is blinking) to the desired value.
2. To Auto-Tune
A. Press SET KEY
until upper display reads (At) and lower display reads (no). Press the SHIFT KEY <,
the
first digit will begin blinking. Press UP or DOWN key to change lower display from NO to
YES and
press SET KEY to enter value and start Auto-tune of process.
B. The controller
should now automatically increase the process temperature (upper display) to the
temperature as entered for the set point (lower display).
Alarm Mode (If desired to use alarm)
To enter a temperature for the
alarm operation
A. Press the SET KEY
until the upper display reads AL1. The lower display will read the alarm
temperature in
degrees.
B. Press the SHIFT
KEY to change the alarm temperature. The digit will blink that is to be changed;
and use
the UP/DOWN KEYS to change the value of the digit.
The alarm is preset for a high
limit operation absolute value - code 15
If it is desired to change the type of alarm operation,
the display must be changed
to level #3 as follows:
A. Press the SET KEY
and hold for 5 seconds until display shows P1 on upper display (release KEY)
B. Then press SET KEY
and then SHIFT KEY < and hold both KEYS for 5 seconds until upper
display reads in
INP1.
C. Press SET KEY until upper display
reads Ald1
D. Change lower
display to read 15 by pressing SHIFT KEY to blink and UP/Down KEYS to change
value and SET
to enter value.
There is a level #2 of Parameters
which it is not usually necessary to change but they can be observed
(or changed) as
follows:
Press the SET KEY for 5 seconds until
upper display reads P1 and the lower display will read the
proportional band ( 0 to 200%).
The PID parameters can now be observed by pressing the SET KEY
to scan through the PID
values. If it is desired to change any of the values manually the SHIFT KEY
and UP/DOWN
KEYS must be used as in the previous sections to change the values of each digit.
NOTE:
Level 3 is also used to select the
type of thermocouple and degrees F/ degrees C as well as the type
of alarm action as
previously outlined.
Level 3 is again accessed by pressing
the SET KEY and then the SHIFT KEY and holding both for 5 seconds
until upper display
reads in INP1.
A. Enter J6 on lower
display for 0-2192 deg F range or J1 ( 0-392 deg F) , J2 ( 0-752 deg F), J3 ( 0-1112 deg
F),
J4 (0-1472 deg F) or J5 for 0-1832 deg F. Change J to K for type K chromel alumel
thermocouple. See Input selection table in Instruction manual for other thermocouples.
B. To change from deg
F to deg C use SET KEY to scan until bottom display reads F or C.
Change from F to C or
vice versa by pressing the SHIFT KEY <, the first digit will begin blinking and then
UP
or DOWN KEY to enter value.
Operation of Auto/Manual Function
A. Press A/M key and
upper display will read OUtL. The lower display will read the percentage
of output (0-100%).
B. Press the shift key < to
change the percentage output manually. The digit will blink that will be changed by use of
UP/DOWN keys. Unlike entering the temperature set point and other parameters, the 4-20 ma
(0-100%) manual output changes as the value is entered. If the up/down keys are held down,
the display and 0-100% output will scroll continuously from the least significant digit
(the one that is blinking) to the desired value.
C. The percent output can be
observed on the 0-100% LED bargraph arrows under the digital display.
#Note:
If the A/M key is pressed again, the displays will
revert to reading process temperature and set point temperature and change
to automatic control. If the A/M key is not used, the display, after 1 minute, will revert
to reading the process temperature and set point temperature but will stay in the manual
mode with the 0-100% (4-20 ma) output staying the last value entered. It will stay in the
manual fixed 4-20 ma output until the A/M key is depressed to enter automatic control of
temperature. If it is desired not to go to automatic control but change the manual output,
the A/M key has to be pressed twice in succession and the display will then read the
0-100% output and the output can be changed as previously outlined.
