K0430 Issue No. 2 14
Current to Pressure Converter (I-P) Task
A - External pressure source B - Pressure to current device (24V) C - Barrier
D - Safe area E - External supply
•Use the up and down cursor keys to adjust the loop current to the required
value. 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 LOOP
message indicates either an open circuit supply loop (or no external supply).
Pressure Switch Test (P-SWITCH) Task
A - 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 switch
operating point. Screw the volume adjuster in until the switch operates (the
operating pressure of the switch is then written to the display).
• Reduce pressure until the switch releases (indicated by the switch symbol). The
release pressure is then written to the display and the hysteresis displayed.
