Temperature Controller Without Datalogger Model: TC-R200 :-

Temperature Controller TC-R200 Features:-

      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 also has an additional relay, Type-Relay, which can be used with different functions as below:

1. To create Flashing-Error if temperature is not reaching to required
2. Set-point.
3. To create On-Type(Not Flashing) Error if temperature is not reaching to required Set-point.
4. It can be used as In-Range to set relay on when temperature is In-Range (Settable Range-Low to Range-High).
5. Two Point Controller as Low-Point.
6. Two Point Controller as High-Point.
7. 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

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

• Measure-Mode

At power on and if none of switch is pressed display start showing Measured Temperature value in centigrade if calibrated correctly and relays start functioning as per parameter settings. Press Sw3 (Enter-Arrow) to see Set-Point, Or press both Sw1 (Up-Arrow) and Sw2 (Left-Arrow) to Program Parameters.

• Program-Mode

There are 14 parameters can be viewed/edited one by one in this mode.
When user is in Measure-Mode and presses Sw1 and Sw2 both together, user enters in this mode with display shows first parameter 5P.

^Go Back

Parameters are abbreviated on display and are shown as follows:

1. Set-Point abbreviated as 5P.
2. Proportionate/Control as Po.
3. Band as bA.
4. Proportionate-Time as Pt.
5. Alarm-Time as At.
6. Delay-Time as dt.
7. Type as ty.
8. Range-Low as rL.
9. Range-High as rH.
10. Low-Level Sense/No-Level Sense as LL.
11. Heating/Cooling as HE.
12. Lock-Edit/No-Lock as LE.
13. Calibrate-Low as CL.
14. Calibrate-High as CH.

To exit any time from Program mode press both Sw1 (UpArrow) and Sw2 (LeftArrow) again.

Note: If this mode is left for sometime without any action for preset internal time, Measure-Mode will be established automatically.
