TEMPERATURE CONTROLLER
OPERATION MANUAL

Before using please check whether range, input and output match your requirement.
Thank you for using our microprocessor temperature controller, we have obtained CE certification (LDV: D/N EN61010-1; EMC EN 55 022 1994/A1: 1995/A2: 1997, EN 61 000-3-2: 1995/ -3-3: 1995, EN 61 000-4-2: 1995/ -4-3: 1996/ -4-5: 1995/ -4-6: 1996/ -4-8: 1993/ -4-11: 1996/ EN 50 204: 1995) for all our products since January, 2002. We have also computerized our QC process and testing to provide high quality standard, low price and high functionality in our products.

1.1 DISPLAY

PV:Process value,4 digit display (red color)

SV:Setting value,4 digit display (green color)

    1. LED

OUT1 :Output 1,green color

OUT2 :Output 2,green color

AT :Auto Tuning,yellow color

PRO :Program,yellow color --- Only available for PFY models.

AL1 :Alarm 1,red color

AL2 :Alarm 2,red color

AL3 :Alarm 3,red color

MAN :Manual,yellow color

*Note: When error occurs, the MAN will light up, and will reset output percentage to zero.

    1. KEY

SET :MODE & SET key

:SHIFT key
:DOWN key (Setting value –1, -10, -100, -1000)
:UP key (Setting value +1, +10, +100, +1000)

A/M :Auto/Manual key.

Automatic :The output percentage is determined by internal

calculation.

Manually :The output percentage is determined by manually set

OUTL at User Level.


  1. Auto tuning

    1. Once AT is set YES,auto tuning is to be performed.

    2. After auto tuning is finished,a new set of PID parameter is

generated internally to replace the existing PID parameter.

* Auto tuning allows the controller to automatically adjust the PID parameter, and is suitable for use when temperature control is not accurate enough.

    1. ATVL=auto tuning offset,and it will be deduced from SV

(it can prevent over shoot during auto tuning)

SV-ATVL=Auto-tuning value,ATVL=auto tuning offset

Ex.SV=200℃,ATVL=5,Auto tuning point is at 195℃

During auto tuning the PV value will oscillate around 195℃.

Hence PV will not go over 200℃.

* In programmable model,ATVL means Auto-tuning point

    1. Auto tuning failure

Possible Cause 1: ATVL is too big. (If not sure,set ATVL=0)

Possible Cause 2: System time is too long.

(Set PID parameter individually)



  1. Error information

DISPLAY

DESCRIPTION

IN1E


Open circuit of main control sensor.

ADCF

A/D converter failed.

CJCE

Cold junction compensation failed.

IN2E

Open circuit of sub control sensor.

UUU1

PV exceeds USPL.
