MANUALPC-2010 CHAPTER IV - OPERATION Page 32
Selecting YES for FEED LOCKOUT will inhibit any chemical
feed from occurring in case of alarm. Selecting NO will allow
feeding to continue. This may be used to continue feeding an
oxidizer or sanitizer even if the sensor reading is sometimes
low, such as in an overcrowded spa.
Setting ALARM BUZZER to NO disables the buzzer in an
alarm condition. There is also a general buzzer shutoff option
in the Configuration Menu.
1.5 – High Alarm
The ALARM HIGH value is set to generate an alarm when the
ORP reading rises above the set value. After the alarm value
is set, the ALARM OPTIONS screen is shown, asking whether
a high alarm condition should stop the feeder and activate the
alarm buzzer.
1.6 - Time Limit
The TIME LIMIT sets the maximum allowed time (in minutes)
for continuous oxidizer feed. This acts as a safety feature to
prevent overfeeding in case of malfunction of the chemical
feeder or as an alarm if the feed tank runs empty. The
standard (default) value for ORP is 15 minutes.
When in alarm, Time Limit is reset by highlighting the value
and pressing "OK". To defeat the safety timer, enter zero (0).
1.7 - Run Time
T
he RUN TIME line displays two separate values: the amount
of running time in minutes for each current activation event and
the total run time since last reset to zero.
To reset the cumulative run time, enter zero in the far right
column. To reset only the current run time, highlight Time Limit
value and press “OK”.
The Total Feed Time submenu 1.7.1 is used to show the feed
time from a chemical tank since last reset to zero. Knowing
the pump feed rate, it can be used to monitor the emptying of
the tank and set a low-level alarm. This feature is particularly
useful for remote monitoring of the chemical tanks.
1.8 - Last Shock
The LAST SHOCK line shows the last date of Shock
Treatment. It is shown for display only, no adjustment can be
made to this date.
Press the RIGHT ARROW key to enter the Submenu 1.8 for
Shock Treatment, De-shock and Chemical Saver.
1.8.1 - Shock Treatment
Shock Treatment refers to treatment with an elevated level of
oxidizer. It should be performed from time to time to prevent
the accumulation of noxious chemicals (chloramines) or
biological forms (algae, etc.).
Submenu 1.8.1 is used to set the parameters for the shock
treatment program.

1.8.2 - Deshock
Deshock refers to the addition of a reducing agent (such as
S
odium Thiosulfate) which is used to reduce excessive
amounts of oxidizer introduced during Shock Treatment.
1.8.3 - Chemical Saver
Submenu 1.8.2 is a weekly program to reduce chemical usage
by stopping chemical feed when the facility is not in use, such
as at nighttime or on weekends.
