1. Front Panel Overview

Фронт view of the RWRAPS REX-C100 Digital PID Temperature Controller — **1-сүрөт: алдыңкы панел.** This image displays the front face of the REX-C100 controller. It features a dual digital display, with the upper red display showing the Process Value (PV) and the lower green display showing the Set Value (SV). Control buttons for 'SET', 'Up', 'Down', and 'Left/Right' navigation are located at the bottom. Indicator lights for 'OUT1', 'AT' (Auto-Tune), 'ALM1', and 'ALM2' are visible on the left side.

The front panel (Figure 1) provides the primary interface for monitoring and adjusting the controller's settings. The upper display (PV) shows the current measured temperature, while the lower display (SV) shows the target temperature. The buttons allow for navigation through menus and parameter adjustments.

2. Wiring Terminals

Арткы view of the RWRAPS REX-C100 Digital PID Temperature Controller showing wiring terminals — **Figure 2: Rear Wiring Terminals.** This image shows the back of the REX-C100 controller, revealing the screw terminals for electrical connections. There are ten clearly labeled terminals (1 through 10) arranged in two columns, designed for secure wiring of power, sensor input, and output.

Figure 2 illustrates the rear wiring terminals. Ensure all connections are made securely to prevent operational issues. Refer to the wiring diagram for correct terminal assignments.

3. Электр схемасы

Wiring diagram for RWRAPS REX-C100 Digital PID Temperature Controller — **Figure 3: Wiring Diagram (Side View).** This image displays the side of the REX-C100 controller with a detailed wiring diagram label. It shows connections for power supply (terminals 1 & 2, 100-240VAC), 0-20mA output (terminals 3 & 4), alarm output (terminals 6 & 7), and sensor input (terminals 8, 9, 10 for RTD or Thermocouple). The model number REX-C100 and supply voltage range are also visible.

The wiring diagram (Figure 3) is crucial for proper installation. Follow these guidelines:

Power Supply (Terminals 1 & 2): Connect your 100-240VAC, 50/60Hz power source here.
Current Output (Terminals 3 & 4): Connect your control device requiring 0-20mA input. Terminal 3 is positive (+), Terminal 4 is negative (-).
Alarm Output (Terminals 6 & 7): Connect your alarm indicator or relay here.
Sensor Input (Terminals 8, 9, 10):
- For RTD (e.g., Pt100): Connect to terminals 8, 9, and 10.
- For Thermocouple (TC): Connect to terminals 9 and 10. Ensure correct polarity.

Маанилүү: Always ensure power is disconnected before performing any wiring to prevent electric shock.

Иштөө нускамалары

1. Power On and Initial Display

Upon powering on, the controller will display the current process value (PV) on the upper red display and the set value (SV) on the lower green display. Ensure the sensor is correctly connected and functioning.

2. Максаттуу температураны (SV) коюу

басыңыз SET button once. The SV display will begin to flash.
колдонуу Up (▲) жана Төмөн (▼) arrow buttons to adjust the target temperature.
колдонуу Сол оң (◀ / ▶) arrow buttons to move the cursor for faster adjustment of individual digits.
басыңыз SET button again to confirm the new SV and exit the setting mode.

3. Auto-Tune Function (AT)

The auto-tune function automatically calculates optimal PID parameters for your specific system, ensuring stable and accurate temperature control.

Set your desired target temperature (SV) as described above.
басып, кармап туруңуз SET button for approximately 3-5 seconds until the 'AT' indicator light begins to flash.
The controller will now cycle through heating and cooling to determine the system's characteristics. This process may take some time depending on your system's thermal mass.
Once auto-tuning is complete, the 'AT' indicator light will stop flashing and remain off. The controller will then operate with the newly calculated PID parameters.

Эскертүү: It is recommended to perform auto-tuning whenever the system's thermal characteristics change significantly (e.g., new heater, different load).

4. Advanced Parameter Settings

For advanced users, the controller offers individually programmable control parameters (P, I, D, control period, digital filter coefficient, etc.). Accessing and adjusting these parameters typically involves pressing and holding the SET button for an extended period (e.g., 5-10 seconds) to enter the parameter menu. Refer to the detailed parameter list in the full technical manual for specific codes and ranges. Incorrect settings can lead to unstable control.
