Tank Full Restart
The tank full restart is the delay before the MRO unit starts when a tank full
condition clears. This delay can be in minutes or in seconds. The TF Restart
Setpoint selects seconds or minutes.
Tank Full Override
A timed tank full override can be initiated when the MRO unit is shut down due
to a tank full condition. Pressing the Alarm Silence/Reset key for 3 seconds
during a tank full condition will enable the tank full override. The RO will start
and TF OVERRIDE 9 will show on the display. The number is the minutes
remaining in the override timer. When the override times out, the unit will
return to the tank full shut down condition. The TANK FULL OVERRIDE will
divert all water to the drain, whether the water quality is good or bad coming
into the RO.
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 [180 seconds (AAMI RD62 standard)] when the
Alarm Silence Setpoint is programmed to the factory default 3. 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.
