Temperature Controller VTR-2

Product catalog summary

Product Overview:
The VTR-2 Temperature Controller is designed for use with Pt100 or Pt1000 sensors to monitor and control temperatures in food and biopharma applications. It features a compact design, universal power supply, and an LC display for menu guidance.

Specifications:

Housing: ABS for rail mounting, dimensions 22.5 x 111 x 120 mm, IP 20 protection class.
Temperature Range: Operating 0...+55 °C, Storage -10...+55 °C, Humidity 0...95% non-condensing.
Input: Pt100/Pt1000, 3- or 4-wire, sensor current 500 μA, wire compensation max 100 Ω.
Output: Analog 0/4...20 mA or 0...10 V, switching contact max 250 V / 3 A AC.
Accuracy: ≤ ±0.1% of measurement range, temperature drift ≤ 0.01%/K.
Power Supply: 24...255 V AC/DC, power consumption 2.5 W / 4.5 VA.

Features:

Menu guidance with LC display.
Settable operating point, hysteresis, and delay.
Switching function adjustable between normal and inverting.
Analog output options and sensor monitoring.
Display in °C or °F.

Functionality Test:

Connect the temperature sensor or simulator and auxiliary power supply.
Set unit parameters via the menu.
Check switching function, hysteresis, and sensor monitoring.

Operation and Adjustment:

Enter 'SET' mode by holding the 'set' button for 5 seconds.
Select and adjust parameters using 'up' and 'down' buttons.
Save changes or exit without saving as needed.

Standards and Guidelines:

Complies with Electromagnetic Compatibility Directive 2014/30/EU and Low Voltage Directive 2014/35/EU.
Not suitable for explosive areas or security-relevant equipment.

Disposal:

Devices must be recycled according to national laws and not disposed of with household trash.

Electrical Connection | Parameter Functionality test 1. Connect temperature sensor or simulator at input (KL 1 to 4). In doing so, take heed of the 3-wire or 4-wire connection (in accordance wit the software configuration). 2. Connect the auxiliary power supply (KL 9/10). 3. Set unit parameters (e.g. setpoint SP to 100 °C) as described above via the menu. 4. Check the switching function by slowly increasing or decreasing the input signal until the setpoint is reached. 5. Check the required hysteresis and operating delay by altering the input signal. 6. Check the sensor monitoring system by disconnecting...

Advice Measured values are not recorded nor are switch outputs changed while the module is in "SET" mode. Should no further buttons be actuated within approx. 30 seconds, the unit returns automatically to operation mode and any alterations made to the parameters up to this point are discarded. The same occurs when the "SET" mode is exited using the menu point "cancel". The unit then operates with the last previously saved values. Exiting the "SET" mode via the menu point "Reset" restores the parameters to their factory default values. OperationAdjustment 1. Actuate the "set" button for at least...
