SENSORS FOR FOOD AND BIOPHARMA. Application / Specified usage ■ The temperature controller VTR-2 is used in conjunction with the temperature sensor Pt100 or Pt1000 to easily control and monitor temperatures. Features ■ Menu guidance using LC display ■ Settable operating point, hysteresis and operating delay ■ Switching function "min" / "max" can be toggled ■ Can be connected to PT100 or PT1000 ■ 3 or 4-wire-technology ■ Analog output: 0...10 V or 0/4...20 mA (optional) ■ Sensor monitoring ■ Display of the actual value in either °C or °F,as selected ■ Connection via pluggable terminal blocks ■ Narrow design (22.5mm) ■ Universal power supply 24/20...255 V AC/DC

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...

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...
