How to fix a large temperature error or input error (S.Err display) on my Omron E5CC-800?
If you're seeing a large temperature error or an input error (S.Err display) on your Omron Temperature Controller, it could be due to: * An input type mismatch. Check the sensor type and reset the input type correctly. * The thermometer not being installed properly. Check the thermometer installation location and polarity and install correctly.
What to do if the keys will not operate on my Omron E5CC-800 Temperature Controller?
If the keys on your Omron Temperature Controller will not operate, it is possible that setting change protect is ON. Turn OFF setting change protect.
What to do if the temperature is not rising on my Omron Temperature Controller?
If the temperature isn't rising on your Omron Temperature Controller, consider these possibilities: * The specified operation may be unsuitable for the required control. Select either forward or reverse operation, depending on what you need. * The heater may be burnt out or deteriorated. Check the heater. * The heater capacity may be insufficient. Check the heater's heating capacity. * A cooling system might be in operation. Check if a cooling system is running. * Peripheral devices might have a heat prevention device operating. Set the heating prevention temperature setting to a value higher than the set temperature of the Digital Controller.
Why won't my Omron E5CC-800 operate?
If your Omron Temperature Controller isn't operating, check the following: * Ensure the RUN/STOP mode is set to RUN. If STOP is lit on the display, control is stopped. * Check if the thermometer has burnt out or short-circuited. * Ensure thermometer lead wires and power lines are in separate conduits, or wired using a more direct path, to avoid noise. * Connect the thermocouple's lead wires directly, or connect a compensating conductor suitable for the thermocouple, instead of using copper wires. * Verify that the installation location of the thermometer is suitable. * Set a suitable input shift. If no input shift is needed, set the input shift value to 0.0.
Why won't the output turn ON on my Omron E5CC-800?
If the output on your Omron Temperature Controller will not turn ON, consider the following: * Ensure the RUN/STOP mode is set to RUN. If STOP is lit on the display, control is stopped. * Select either forward or reverse operation, depending on the required control, as the specified operation may be unsuitable. * Adjust the hysteresis value to a suitable level, as a high hysteresis may be set for ON/OFF operation.
What causes unstable control in my Omron E5CC-800?
If the control is unstable on your Omron Temperature Controller, it may be due to: * Loose terminal screws. Retighten terminal screws to a torque of 0.43 to 0.58 N·m. * The internal components reaching the end of their service life. Replace the Digital Controller and all other Digital Controllers purchased in the same time period.
Why can't I shift levels on my Omron E5CC-800 Temperature Controller?
If you cannot shift levels on your Omron Temperature Controller, it may be due to operations being limited due to protection. Set the operation/adjustment protect, initial setting/communications protect, and setting change protect values as required.
Why is my Omron E5CC-800 Temperature Controller overshooting, undershooting, or hunting?
If your Omron Temperature Controller is experiencing overshooting, undershooting, or hunting, it could be due to several reasons: * If ON/OFF control is enabled, select PID control and execute either ST (self-tuning) or AT (auto-tuning). When using self-tuning, turn ON the power supply to the Digital Controller and load (heater, etc.) at the same time, or turn ON the load power supply first. * If the control period is too long compared to the temperature change speed, shorten the control period, keeping in mind that a cycle of 20 ms minimum is recommended to preserve the service life of the relays. * If the PID constant is unsuitable, set appropriate PID constants by executing AT (autotuning) or manually setting PID constants individually. * If there's an SSR operation fault, use ...
