Changing and Saving Values in Configuration.
This chapter only explains the different selections available and how to
change modes or values. Look up “OPERATION” for more details of when
to use different settings.
General:
Table 1 (pH) and Table 2 (mV) is an overall diagram of all the variables
that can be changed in configuration. The LCD display shows a mode or
value and the appropriate LED lights up to show the position presently
showing. Pushing the encoder prepares to change this value. This is
indicated by the LED flashing. To save a change push until the yellow
“SAVE” LED flashes twice. The change is now saved in non-volatile
memory and will be used by the PMH-2.
This manual from now on will say:
Pushing the encoder: ‘PUSH’
Pushing the encoder until the save LED flashes twice: ‘SAVE’
Clockwise direction of the encoder knob: Rotate ‘CW’
Counter-clockwise direction of the encoder knob: Rotate ‘CCW’’
Either direction of the encoder: “Rotate’
F
To change large numbers quickly rotate the encoder in a “flicking” manner.
Dosing mode is selected for up [UP] or down [dn].
Setpoint is selected between 0.00 to 14.00pH or 000 to 1000mV
Next select the relay output mode. There are three options.
Normal dosing [no.d] , Normal Proportional dosing [no.P] and
Adaptive Proportional dosing [Ad.P]
(pH only) Temperature compensation is selected manually in +
o
C mode.
‘PUSH’ and dial up the new temperature. Range is 0 to 100
o
C.
Connecting a PT100 temperature sensor enables the PMH-2 to use
automatic compensation. Select SoC for manual or AoC for auto com-
pensation. In AoC mode the actual temperature is displayed.
Exit without saving by rotating the encoder (Temp LED goes off) and then
‘PUSH’. Press ‘SAVE to accept automatic compensation.
