Troubleshooting If any malfunctions occur, refer to the following items, after checking the power supply to the controller. 10.1 Indication Problem PV display is indicating ]. [ [ ] is blinking on the PV display. [ ] is blinking on the PV display. The PV display keeps indicating the value which was set in the Scaling low limit setting. V1.1 • 10/2006 Presumed cause and solution • Control output OFF function is working.
Operating Instructions Temperature Indicating Controller CS4S The indication of PV display is abnormal or unstable. The PV display is ]. indicating [ • Is sensor input or temperature unit (°C or °F) correct? Select the proper sensor input and temperature unit (°C or °F). • Sensor correcting value is unsuitable. Set the value suitably. • Is the specification of the sensor correct? Set the sensor to the proper specification. • AC leaks into the sensor circuit. Use an ungrounded type sensor.
