Use as a PID controller: This type of control can be set in the following three steps:Step 1Define the logic output (Out 3) as a regulatingoutputStep 2Select the PID type of controlStep 3If you so wish, the factory-set standard PIDparameters can be determined automaticallyby means of AUTOTUNING and saved in thedevice.25OPErBasic Display2s25OPErBasic Display2s25OPErBasic Display2s>SP>SPConF>PAn>InPOFF>rEGSSet>OutSSettunEContO1F25SSetContautoO:FAO2Fmax.12hContautoPidO3FSSetSSetContO3FautoOFF3sO3Fauto!rEGSSetO3F3s6

DPC III Type 17-8821-4.2222303.00 Operating Instructions8. Operation, MaintenanceThe owner/managing operator of an electricalsystem must ensure that the operating equipmentis in proper condition, operate it in accordancewith instructions, monitor it and carry outpreventative and corrective maintenance.Each piece of electrical equipment must beselected according to its suitability.Before being put into operation again, theapplicable laws and directives must be observed.The safety instructions given must be followedbefore maintenance work is done or failuresrectified.9.2. Temperature alarmsThe floating relay output OUT 2 is factory-set as a group alarm output in the „normally energised /NC = normally closed“ mode of operation. Accordingly, the contact remains closed (relay activated)as long as there isn’t any fault. This principle of action allows wire breakage and power failure to bedetected.The following shows this effect in detailϑ Actual value(PV)AL1HAL1LHysteresisHAL1 = 1KHysteresisHAL1 = 1K9. Alarm management9.1. Measuring circuit monitoringThe connected temperature sensor system(Pt100) is monitored for the following faults:LowalarmON■■■Short-circuit sensorInterruption sensorSensor undershooting or overshooting ofthe measuring rangeHighalarmONONWhen one of these faults occurs, the devicereacts as follows:OUT 220 2220 22■■■Contact load relay (OUT 1) opensContact alarm relay (OUT 2) opensLogic output (OUT 3) switches offMainsvoltageONON10.
