Deltabar PMD50 HART Commissioning WARNING Process pressure above or below permitted maximum/minimum! Risk of injury if parts burst! Warnings are displayed if the pressure is too high. ‣ If a pressure smaller than the minimum permitted pressure or greater than the maximum permitted pressure is present at the device, a message is output. - Page 18 Commissioning Deltabar PMD50 HART Setting the lower range value (pressure or scaled variable) The desired pressure for the lower range value is present at the device. Press "Zero" for at least 3 seconds. After "done" appears on the color display, the applied pressure is accepted for the lower range value.
