SET POINT ONE MODE refers to the first of THREE available
a
larm Set Points. The Set Point Mode is used to activate alarm
devices (if desired) and designate what condition the alarm
represents. The selections are: OFF, LOW, or HIGH. If the SET
POINT MODE setting is left in the factory default OFF position, no
additional parameters will be made available for that particular
alarm set point. However, if LOW or HIGH Mode is selected, the
alarm is activated and the first of four (A thru D) Set Point
parameters will be displayed as follows.
A) SP1 SRC (SET POINT ONE SOURCE) refers to the source of
the alarm. The choices, depending on which Control Scheme is
active, will be FLOW (water flow level), VALVE (gas feed rate) and
RES (Residual level).
NOTE:
When using Feed Forward (FF) Control, alarm set points
are only available for the Chlorination (upstream) valve to eliminate
the possibility of conflicting settings with the De-chlorination
(downstream) valve.
B) SP1 RELAY (SET POINT ONE RELAY). There are three (K1,
K2, and K3) relay switches available on the SMARTVALVE’s
Power Supply Board (7071). Each active alarm Set Point MUST
be assigned to one relay. Each relay may be used for more than
one set point.
C) SP1 DELAY (SET POINT ONE DELAY) allows the user to set
a time delay from when the alarm set point level is reached until
the alarm actually turns on. The range available is 0 to 60 seconds.
Factory setting is 0.
D) SP1 HYS (SET POINT ONE HYSTERESIS) allows the user to
set a level above (or below) the set point that the source must
return to before the alarm turns off. This setting is based upon the
units used to measure the alarm source. e.g.- If the water FLOW
level is the alarm source and the range is in percentage (%) with
a LOW level set point of 10%, a 2% hysteresis setting would
require the water level to reach 12% before the alarm turns off.
Factory setting is 0.
SET POINT TWO MODE is used to activate (or de-activate) alarm
Set Point No. 2. As is the case with Set Point No.1, the choices
are: OFF, LOW, or HIGH. The factory setting (OFF) will de-activate
the alarm and LOW or HIGH will activate it. If the alarm is activated,
follow the same steps explained for alarm Set Point No. 1.
SET POINT THREE MODE. Follow the same steps as explained
for Set Points No. 1 and 2.
LOCK CONTROL PARAMETERS is the final parameter in the
Configuration Mode. It is used to allow (or deny) access to the
Control Parameters from the OPERATIONAL MODE. Selecting
NO (factory setting) allows access to the parameters. Selecting
YES denies access.
NOTE:
The Control Parameters are used exclusively for systems
set up for Compound Loop OR Residual Only Control. They are
explained in detail in the next section (7.0 System Startup).
