CONFIGURATION
Looking at menus and values without changing or saving.
The PMH-2 is now in ‘RUN’ mode and processes the mV signal, output
and alarm relays and the signal output. This condition is indicated with the
green ‘RUN/CONFIG’ light. Turning the encoder knob has no effect.
Now push the encoder knob. The LED changes to flashing red. Turn
the knob clockwise. The LED changes to steady red and the display
shows CnF . Now push to move to the first configuration mode. The
display shows UP . Slowly rotate the knob to sweep through all the modes:
Dosing up / down,
Setpoint,
Dosing mode for relay1
Temperature configuration (with pH selected only)
Low / high alarm or dosing mode for relay2
Flow switch
4-20mA Signal
End
The corresponding LED lights up for each of the above position to show
which mode is indicated with the LCD display.
The next step shows End , here you can exit back to ‘RUN’ by pushing
the encoder or continue to step clock-wise or anti-clockwise to look at the
configurations again. There is no need to exit manually as the PMH-2
automatically returns to ‘RUN’ after 2 minutes if left anywhere in the
configuration or calibration menu.
F
The PMH-2 automatically returns to ‘RUN’ after 2 minutes if left anywhere
in the configuration or calibration menu.
If a program mode is entered inadvertently by pushing the encoder,
simply push again until the ‘SAVE’ LED flashes. The same mode or value
is retained as was previously programmed.
