a. Adjustment range of “Permeate Conductivity High” alarm is 0-50 S/cm for Rev D3
software; 0-200 S/cm for Rev E0 or higher software.
b. Below 200 S/cm, there are 2.5 units of specific conductance (S/cm) per unit of
Total Dissolved Solids (ppm or mg/L as CaCO
3
).
c. Shutdown alarms with adjustable delay (1-99 sec).
d. If an acid injection pump is installed, the high pH alarm determines when the
chemical pump turns on. After the chemical pump lowers the pH to 1.8 units below
the alarm setting, the pump will be turned off.
e. Shutdown within one second (non-adjustable).
f. Set alarm limit at 8 psi (6[barX10]) greater than drop observed during data collection
fro QA test form.
g. Set alarm limit at 1.5X the drop observed during data collection for QA test form.
h. Set alarm limit at 60% of flow observed during data collection for QA test form.

a. An RO pump delay of 0 will disable the RO pump.
b. Select zero (0), if permeate divert option is not installed. Select 2 min, if it is
installed.
c. When enabled, typical settings are auto-on period of 4 hours, and auto-on duration
of 15 minutes.
