The Water FLOW UNITS are available in
%
(percent),
GPM
(gallons per minute),
MGD
(million gallons per
day),
L/s
(liters per second),
m3s
(cubic meters per second), and
m3d
(cubic meters per day). Factory
set in %.
NOTE: To change this parameter and any other Configuration parameter, simply press (ADJ)
adjust. Use the UP and DOWN buttons to scroll to the preferred selection. Press ENTER to accept,
then press NEXT to continue to the following parameter.
Sets the maximum WATER flow according to the selected FLOW UNITS. Since the factory setting for
Flow Units is percent, the FLOW RANGE is set to
100
(%).
Allows the Flow Signal to be averaged over a specific time period before the SMARTVALVE makes any
adjustments. This helps prevent wear and tear on the stepper motor and feedback potentiometer. The
settings available are 0.2, 0.4, 0.6, 0.8, 1, 2, 3, 5, 8 & 10 seconds. Factory set at
1
.
Units used to monitor and regulate the gas feed rate. The choices are PPD (lbs. per day), g/h (grams per
hour) and kg/h (kilograms per hour). Factory setting is
PPD
.
Valve Full Scale is the maximum gas feed rate (capacity) of the SMARTVALVE based upon the Valve
Units.
IMPORTANT:
The SMARTVALVE is sized to the customer’s specification at the time of purchase. If the
Full Scale of the SMARTVALVE needs to be changed, the valve plug and other system components may
also need to be changed.
SET POINT ONE MODE refers to the first of THREE available alarm 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 will be
FLOW
(water flow level) and
VALVE
(gas feed rate).
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.
