IMPORTANT:
The PanaFlow HT’s magnetic keypad enables programming of the instrument through the glass
faceplate without removing the cover. Thus, all programming procedures may be performed while the
unit is installed in a hazardous area.
Above the display, the red light is for power indication and the green light is for system health indication. Once system
power is applied, the red light will stay on until power is lost. The green light will only be on when system is measuring
without error. If the instrument detects any error, the green light will turn off. Also, when the Operator enters Configure
mode, the instrument stops measuring, so the green light will be off.
Six keys on the magnetic keypad enable users to program the PanaFlow HT:
