    This can lead to a destruction of the current transformer. 4) Insert the CX plus into the panel cut-out and fix it by using both fixing clamps. 5) Connect the grounding cable to the intended terminal on the backside of the device.
  • Page 6 9) If the device is connected correctly, the display will light up for one second and all symbols will be displayed during a display test. 10) Now the First Setup can be started by confirming YES. The different settings must be adjusted according to the power grid. 11) After a successful First Setup, the display shows AUTO.
  • Page 7 Frequently asked questions during commissioning 1) AUTO is not shown → control is switched off Possible reasons: Manual operation activated; control is switched off; temperature is too high; current is less than 5 mA; voltage or THD of the voltage are inadmissible 2) U ALARM is shown →...

  • Page 14 SETUP – Controller setup The Quick Start menu (100) and the Expert menus (200 – 800) can be entered by pushing the  button. The latter one requires the input of a PIN code. Nominal voltage Current transformer factor Voltage transformer factor Automatic initialization The phase angle between voltage and current is determined and which stage outputs are used.
  • Page 15 Automatic initialization (Ai) The Automatic initialization determines the phase angle between voltage and current and detects which stage outputs are used. The Automatic initialization can be activated in the SETUP menu (SETUP/100/Ai or SETUP/207 = YES) and starts as soon as the voltage is within the tolerance and the measured current is greater than 5 mA.
  • Page 16 Automatic stage size detection If stage detection is activated (SETUP/308 = YES), the CX plus determines the size of the stages automatically during each switching operation. The detected sizes are stored in the stage database. There, a stage power loss can be monitored.
  • Page 17 Most important Alarm and Error messages The measured voltage is out of the set tolerance. ALARM I Lo The measured current is smaller than 5 mA. ALARM I hi The measured current is higher than 6 A. ALARM The compensation target cannot be reached. ALARM HArU The set THD voltage threshold has been exceeded.
