Pressure Fault
If the pressure fault input becomes active (closes) and stays active for the delay programmed in
the PF Delay Setpoint, the unit will shut down for a pressure fault. The display will show PRESS
FAULT, the alarm lamp will flash and the audible alarm will sound. The pressure fault can be
cleared by pressing the Alarm Silence/Reset key twice.
Auto Reset
If a pressure fault shut down occurs and the Auto Reset Setpoint is programmed to 0, the unit will
remain shut down until manually reset. If the Auto Reset Setpoint is programmed to a value greater
than 0, the unit will automatically clear the pressure fault and attempt to restart after this delay
times out.
Alarm Silence
When a shut down occurs that causes the audible alarm to sound, the alarm can be silenced by
pressing the Alarm Silence/Reset key once. The alarm will remain silenced for 3 minutes. If the
Alarm Silence Setpoint is programmed to a value other than 3, the alarm will resound after this
delay times out. Pressing the Alarm Silence/Reset key will silence the alarm and reset this delay.
Pretreat
If the pretreat input becomes active (closes) and stays active for 2 seconds, the unit will shut down
in a pretreat lockout condition. PRETREAT will show on the display and the unit will remain shut
down as long as the pretreat input is active.
High Conductivity
If the Conductivity reading exceeds the limit programmed the Cond Limit Setpoint for the delay
programmed in the Cond Delay Setpoint, the alarm lamp will light and the HI COND warning
message will show on the display. This warning will clear when the Conductivity drops below the
Setpoint.
When the High Conductivity warning message is active, the RO will alarm, until the Product water
conductivity goes back into the acceptable quality range.
Alarm Output
The Expansion I/O relay 2 has been programmed to operate as an alarm relay. The relay will
energize whenever a warning or alarm condition occurs. The relay will remain energized as long as
the warning/alarm condition is active.
