1 display.This section describes how to check error codes on the display, and the actions to be taken to remedy theproblems.s.errInput ErrorMeaningThe input value has exceeded the control range. (See note.)Note Control RangeResistance thermometer, thermocouple input: Temperature setting lower limit − 20°C to temperaturesetting upper limit + 20°C(Temperature setting lower limit − 40°F to temperaturesetting upper limit + 40°F)ES1B input:Same as input indication range−5% to +105% of scaling rangeAnalog inputActionCheck the wiring of inputs for miswiring, disconnections, and short-circuits and check the input type.If no abnormality is found in the wiring and input type, turn the power OFF then back ON again.If the display remains the same, the Controller must be replaced. If the display is restored, then the probablecause is electrical noise affecting the control system.
Check for electrical noise.Operation at ErrorAfter an error occurs, the error is displayed and the alarm outputs function as if the upper limit has beenexceeded.When the “input error output” parameter in the advanced function level is set to ON, the alarm 1 output turnsON whenever an input error occurs.An error message is displayed when the PV, PV/SP, or PV/MV is displayed.Note When the manual MV, MV at stop, or MV at PV error is set, the control output corresponds to the setvalue.[[[[]]]]Display Range ExceededMeaningThough this is not an error, it is displayed if the process value exceeds the display range when the controlrange is larger than the display range.The display ranges are shown below (with decimal points omitted).• When less than −1,999[[[[• When more than 9,999]]]]204Appendix AActionControl continues, allowing normal operation.

If the display remains the same, the Controller must berepaired. If the display is restored, then the probable cause is electrical noise affecting the control system.Check for electrical noise.ActionThe control outputs and alarm outputs turn OFF. An error message is displayed when the PV, PV/SP, or PV/MVis displayed.When the manual MV, MV at stop, or MV at PV error is set, the control output corresponds to the set value.For alarm outputs, the operation indicators and status normally turn OFF, but they will turn ON if the “close inalarm” parameter for alarms 1, 2, or 3 in the advanced function setting level is set to n-c (Close in alarm).Note Applies to the E5@N-@@H@ and E5@N-@@HH@.e111Memory ErrorMeaningInternal memory operation is in error.ActionFirst, turn the power OFF then back ON again.
If the display remains the same, the Controller must berepaired. If the display is restored, then the probable cause is electrical noise affecting the control system.Check for electrical noise.Operation at ErrorControl output and alarm output turn OFF. (Current output is approx. 0 mA).205Appendix AffffCurrent Value ExceedsMeaningThis error is displayed when the heater current value exceeds 55.0 A.ActionControl continues, allowing normal operation. An error message is displayed when the following items are displayed.Heater current 1 value monitorHeater current 2 value monitorLeakage current 1 monitorLeakage current 2 monitorct1ct2lcr1lcr2Heater BurnoutHS AlarmMeaningWhen heater burnout or an HS alarm occurs, the No.
1 display in the applicable setting level flashes.ActionWhen either heater burnout or HS is detected, the HA indicator lights and the No. 1 display flashes for theapplicable “heater current 1 value monitor,” “heater current 2 value monitor,” “leakage current 1 monitor,” or“leakage current 1 monitor” parameters in the operation level and adjustment level. Control continues, allowingnormal operation.TroubleshootingChecking ProblemsIf the Temperature Controller is not operating normally, check the following points before requesting repairs.
