K0430 Issue No. 2 14Current to Pressure Converter (I-P) TaskA - External pressure source B - Pressure to current device (24V) C - BarrierD - Safe area E - External supply• Use the up and down cursor keys to adjust the loop current to the requiredvalue. Alternatively, press ENTER and use cursor keys to enter a finite value.Cursor keys can then be used to nudge the output either up or down.If required, change pressure units with INPUT key. A flashing CHECK LOOPmessage indicates either an open circuit supply loop (or no external supply).Pressure Switch Test (P-SWITCH) TaskA - External pressure source B - Pressure regulator C - Pressure switch under test• Contact state will be shown on display. When contacts close, buzzer sounds.• To run switch test, close vent valve and press the RUN (F1) key.• Using the hand-pump, increase the applied pressure to just below the switchoperating point. Screw the volume adjuster in until the switch operates (theoperating pressure of the switch is then written to the display).• Reduce pressure until the switch releases (indicated by the switch symbol). Therelease pressure is then written to the display and the hysteresis displayed.PI-PRESSURE INT barOUTPUTNEW VALUECURRENT mAOKTASK : I-PSNAPSHOT MODEF2F1 EXITMax 30VCAT IIDPI 615 ISCD3+-+-CCEDABPRESSURE INT barF2F1RUNCONTACT STATEmax 30VTASK : P-SWITCHSNAPSHOT MODEDPI 615 ISAB3CTaking Measurements
