sound. The alarm can be cleared by pressing the Alarm Silence/Reset key twice.
High Pressure Switch Alarm
If the high pressure switch input becomes active for the the delay programmed in the Hi PSI Sw Delay (126),
the unit will shutdown for a high pressure switch alarm. HI PRESSURE will show on the display, the alarm
lamp will flash and the audible alarm will sound. The alarm can be reset by pressing the Alarm Silence/Reset
key twice.
Conductivity Sensor Warning / Alarm
A high conductivity warning can be enabled by programming the conductivity limit setpoint to a value other
than 0. If the warning is enabled and the conductivity is above the limit for the time programmed in the delay
setpoint, the alarm lamp will light steady and the warning will be shown on screen 2.
A high conductivity shutdown is enabled for a conductivity sensor when the shutdown delay is programmed
to a delay greater than 0. When the limit is exceeded for the sensor for the shutdown delay, the unit will
shutdown for a conductivity alarm condition. The sensor causing the alarm will be shown on screen 1, the
alarm lamp will flash and the audible alarm will sound. Pressing the Alarm Silence/Reset key twice will reset
the alarm.
Auto Reset
If the pretreat input becomes active 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.
Alarm Silence
When an alarm condition occurs, the audible alarm can be silenced by pressing the Alarm Silence/Reset key
once. The condition is not cleared unless the key is pressed a second time. If the Alarm Silence (115) setpoint
is programmed to 0, the alarm will remain silenced. Otherwise, the alarm will resound after this delay times
out.
Auxiliary Pump Control
If the Aux Mode (127) setpoint is programmed to 0, relay 4 is programmed to operate as a auxiliary
(repressurization) pump control. The relay will normally be on at all times. If the tank low input becomes
active for the time programmed in the Tank Low Delay (110) setpoint, the relay will turn off. The alarm lamp
will light steady and TANK LOW will show on screen 2. Once the tank low input clears, the relay will remain
off for the number of minutes programmed in the Tank Low Restart(111) delay setpoint. The relay will then
turn on, the alarm lamp will turn off and the warning will be removed from screen 2.
Boost Pump Control
If the Aux Mode (127) setpoint is programmed to 1, relay 4 is programmed to operate as a boost pump
control. The relay will turn on when the RO starts and will turn off when the RO stops. If the tank low input
becomes active for the time programmed in the Tank Low Delay (110) setpoint, the RO unit will shutdown.
TANK LOW will show on screen 1, the alarm lamp will flash and the audible alarm will sound. Pressing the
Alarm Silence/Reset key will reset the alarm.
