 Soni-Tech       Operating Instruction         TC-R200

It is  3 digit-7 Segment with calibration Temperature-Controller Instrument, used to measure and control temperature for 0 to 200 centigrade from a sensor RTD, has a built-in level controller (Can be used as door switch), and a control-Relay, which can be cut-off if level input is not sensed.

It has an additional relay, Type-Relay, which can be used with different function.

  1) To create Flashing-Error if temperature is not reaching to required

     Set-point.

  2) To create On-Type(Not Flashing) Error if temperature is not

     reaching to required Set-point.

  3) It can be used as In-Range to set relay on when temperature is

     In-Range (Settable Range-Low to Range-High).

  4) Two Point Controller as Low-Point.

  5) Two Point Controller as High-Point.

A relay indication is provided in front for relay status and three membrane-push-buttons, Up-Arrow, Left-Arrow, Enter-Arrow are provided to view and edit parameters.

There are two modes for operation.

(1) Measure-Mode

(2) Program-Mode

(3) Help

Note: If two wire RTD is used then short pin 5 & 6 and re-calibrate to compensate wire length of RTD (If large length).

View/Edit Parameter

________________________________________________________________________

To Exit without saving

To view/edit one of 15 parameters first enter in Program-Mode from Measure-Mode, First abbreviated parameter will be prompted, pressing SW3 second abbreviated parameter will be prompted and so on until you reach to required parameter. After reaching to required parameter user should press Sw2 to view/edit it, this will show parameter value with Right-Most digit flashing.

To view next parameter press Sw3 twice, and so on.

To edit parameter press Sw1, this will increment flashing digit. To change position of flashing digit, press Sw2. Once you edit to desire value press Sw3.

To cancel editing press both Sw1 (UpArrow) and Sw2 (LeftArrow) again.

E.g. User wants to view/edit Proportionate-Time Parameter.

User should be in Measure-Mode. (If not then press Sw1 & Sw2 both together, this will put meter in Measure-Mode.) Now press Sw1 & Sw2 both together, display prompts 5P. Press Sw3, display prompts bA. Press Sw3, display prompts Pt. This is required parameter. Now press Sw2, display will show Proportionate-Time value. If user does not want to edit then user presses Sw1 & Sw2 together, else if user wants to edit then with help of Sw1, user changes digit data and with Sw2 user changes digit position. When necessary changes are made, user presses Sw3, display prompts for next parameter At. Press Sw1 and Sw2 together to quit Program-Mode.

Note: There are two type of Parameter. (1) Having value 0 To 999 (2) Having value Yes or No. For editing of second type of parameter display will prompt y or n, Sw2 will be ineffective, while pressing Sw1 will toggle y to n and n to y. Parameter 2, 7, 10, 11, 12, 13 are of second type.


Set-Point
Set Point (Parameter 1)

________________________________________________________________________

To Exit without saving

Factory set value is 60.

This parameter used along with bA and Po and He and Pt. (5P – bA) value is lower point and 5P value becomes higher point of temperature in which temperature is controlled. There are two cases of control.

(1) When Po is set to n i.e. On-off type is selected.

    Case1: When He is set to y

    Control relay is turned on when Temperature fall to (5P – bA) or

    below it, relay is turned off when Temperature rises to bA or above

    it.

    Case2: When He is set to n

    If He is set to n then relay status is complemented.

    I.e. instead of On-Status it sets to Off-Status and instead of

    Off-Status it sets to On-Status.

(2) When Po is set to y i.e. Proportionate type is selected.

    Case1: When He is set to y

    Control relay is turned on when temperature falls below (5P – bA),

    Control relay is turned off when temperature rises above bA.

    When temperature is in range of (5P – bA) to 5P then it is turned on

    for time = (Pt * (5P – Measure)/(5P –bA)), and turned off for

    time = pt - (Pt * (5P – Measure)/(5P –bA)).

    Case2: When He is set to n

    If He is set to n then relay status is complemented.

    I.e. instead of On-Status it sets to Off-Status and instead of

    Off-Status it sets to On-Status.


Proportionate or On-Off

Alarm Time Setting
Alarm Time (Parameter 5)

________________________________________________________________________

To Exit without saving

Factory set value is 0.

If set value is 0 then no error is generated, else if temperature is not rising or falling as instrument demands for rising or falling of temperature then an error is generated (All Digit of flickers). Type-Relay can be used for Audio-Visual effect or to combine Type-Relay with other instruments.

See Type Parameter7


Delay-Time
Delay Time (Parameter 6)

________________________________________________________________________

To Exit without saving

Factory set value is 0.

At time of power is turned on control relay remains off for given

Delay-Time. This is useful when multiple instruments are used and user wants to prevent high in-rush current of heaters.


Type of function for Type-Relay
Type Relay Function (Parameter 7)

________________________________________________________________________

Factory set value is 0.

When error is generated (Due to AlarmTime or LowLevel On) and

If value is 0 then Type-Relay flickers, else if value is 1 then relay turns on simply.

If value is 0 or 1 then parameter rL and rH will not be shown.

If value is 2 then Type-Relay is turned on when Measure Value is in range of rL and rH including both Parameter rL and rH.

If value is 3 then Type-Relay is used as Low-Point, it turns off when Measure-Value reaches to rH and turns on when Measure-Value rL.

If value is 4 or more then Type-Relay is used as High-Point, it turns on when Measure-Value reaches to rH and turns off when Measure-Value rL.


Range-Low Setting for Type-Relay

Range-High Setting for Type-Relay

Low level sense or not sense
Low-Level Sense or No-Sense (Parameter 11)

________________________________________________________________________

To Exit without saving

Factory set value is n.

If this value is set to y then whenever low level is sensed at Low-Level input, then control relay is cut off and each digit of display is flashed one by one. One has to use only probes for level sensing. Low-Level can also be used as auxiliary digital input. (Short Level input to cut off control relay).


Heating or cooling for control Relay

Factory set value is n.

If this value is set to y then none of the parameter can be edited except this parameter.


Calibrate-Low Point for Instrument (Parameter 14)

________________________________________________________________________

To Exit without saving

This parameter is used along with CH. Digit does not flash nor by pressing Sw1 does not change digit value. User has to connect RTD calibrator at probe input for 0 degree centigrade (100 ohms), display shows calibrator input (If user changes calibrator value then display also changes as per input), wait for display some time, press Sw1 key then press Sw3 to calibrate for Low. This set display low set point of calibration, also similarly calibrate for high point, the only difference is connect RTD calibrator at probe input for 200 degree centigrade (176.87 ohms).

Warning: User should not calibrate Low or High without RTD calibrator.
