Limits Offset 1, Offset 2Both values for Offset 1 and Offset 2 can be set independent of each other and act ona relay together if correspondingly programmed. If a function is activated or if a relay isallocated both settings (Offset 1 and Offset 2) are initially at “OFF”.Work can be carried out with one as well as with both limit indicators.“Offset 1” for alarm in case of an exceeding of the max. deviation between actual andtarget.Switch ON point: actual value = Setpoint +/- offsetSwtich OFF point: Actual value by hysteresis under the switch-on point“Offset 2” for alarm in case of an undercutting of the max. deviation between actual andtargetSwitch ON point: actual value = Setpoint +/- offsetSwtich OFF point: Actual value by hysteresis over the switch-on point- - - - -Offset 1Limits- - - - -Offset 2Limits Offset HysteresisHysteresis switch-on point: In temperature regulation + / - 10 K, otherwise sensors10 % of measurement range- - - - -Offset Hyst.Limits Offset DelayTime delay until indication through relay and alarm symbol.Setting range: 0 - 120 sec.Factory setting: 2 sec.- - - - -Offset DelayExample for temperature regulation; for other modes of operation settings in corresponding sensorunit.Offset 1 for alarm during exceeding10121416182022242628301 3 5 7 9 11 13 15 17 19 21 23 25 27 29[min][°C]ON ON ONON = 15°C + 5 K = 20 °C OFF = 20°C - 2 K = 18 °C16.03.2007v_relais_kuehlen_10k_pos_offset.vsdExample: Setpoint 15.0 °C, Offset +5.0 K, Hysteresis 2.0 KOffset 2 for alarm during undercutting10121416182022242628301 3 5 7 9 11 13 15 17 19 21 23 25 27 29[min][°C]ONOFF = 15°C + 2 K = 17 °C ON = 20°C - 5K = 15 °CON16.03.2007v_relais_heizen_9k_neg_offset.vsdExample: Setpoint 15.0° C, Offset -5.0 K, Hysteresis 2.0 KOperating Instructions Fcontrol – model series FKDM25/32AM-C ProgrammingL-BAL-E214-GB 1446 Index 002 Part.-No.67/99
