Operator Instructions for 1/4 DIN Temperature Controller


Upper Display - Process Temperature (PV)
Lower Display - Set Point Temperature (SV)
LED's Out 1 - 4-20 ma Output
AL1 - Alarm / Condition (red)
AT - Auto tune ON (yellow)


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.

 Secondary Functions

These are functions that are factory set and should not require changing but can be changed from the keypads if deemed necessary.

A. Calibration of thermocouple reading (PV display)

The temperature reading the PV (upper) display can be changed up (+) or down (-) by using the PV05 parameter on the Level 3 screen.

B. Calibration of 4-20 ma Output Models

The 1/4 DIN models which have a manual-automatic transfer mode have a zero (4 ma) and span (20 ma) adjustment available. These are accessed in the Level 3 parameter list as follows: CLO1 - Zero adj. (4ma) CHO1 - Span adj. (20ma)

These adjustments can also be used to set the minimum output to greater than 4ma (0%) or the maximum output 20ma (100%) to less than 100% to prevent the controller from applying full power to the heater load.
