C) TO EXIT THE CONFIGURATION MODE
1) Follow the same steps as explained in Section 4C
(TO EXIT THE ENGINEERING MODE).
NOTE: The system is now ready for start-up.
After all wiring and plumbing has been completed, and the
Engineering and Configuration parameters have been
confirmed, the system is ready for startup.
Once the system is up and running, the TOP LINE of the
SMARTVALVE display screen will show the water
FLOW
rate
in the selected units. The ball float in the remote metering tube
should read the same gas feed rate as shown on the bottom
line of the SMARTVALVE display screen. ALWAYS READ
THE CENTER OF THE BALL FLOAT.
IMPORTANT:
The REGAL 7500 Remote Meter Panel MUST
be configured for AUTOMATIC control.
A) LINEARIZING (CALIBRATING) THE
SMARTVALVE
IMPORTANT:
As previously mentioned, the SMARTVALVE
has been calibrated (linearized) at the factory, however, it is
still recommended that the user/installer checks and becomes
familiar with the linearization process at startup, especially if all
system components HAVE NOT been supplied by Chlorinators
Incorporated. To check the linearization, proceed as follows:
1) ENTER THE ENGINEERING MODE as explained in
Section 5.0.
2) Once in the Engineering Mode, scroll to the
CAL VALVE
parameter.
NOTE:
Linearization will be based upon the factory set,
5-point linearization curve. Confirm this setting by
checking the previous (
LAST
) parameter,
VALVE CAL
PTS
(Valve Calibration Points).
3) While observing the ball float in the Remote Metering
Tube, press the
ADJ
(adjust) keypad button and the
SMARTVALVE will start to drive to the ZERO feed rate
position. The ball should come to rest on the bottom
stop of the metering tube at exactly the same time the
motor stops driving.
4) The Top Line of the SMARTVALVE display screen will
show a ZERO VOLTAGE reading of
0.45 V
.
NOTE:
A voltage reading from
0.41
to
0.49
is acceptable.
IMPORTANT: If for some reason the voltage reading
falls outside of the acceptable range, contact
Chlorinators Incorporated for assistance.
5) Once the correct ZERO voltage reading has been
confirmed, press the
NEXT
keypad button and the
SMARTVALVE will automatically open to the second
linearization point which represents
25%
of the system’s
Full Scale (capacity). e.g.- For a 50 PPD system, 25%
would be
12.5 PPD
.
6) If the reading on the metering tube panel equals the
reading on the SMARTVALVE display screen, press
ENTER
and proceed to step 8.
7) If the readings
DO NOT
match, press
ADJ
(adjust). Use
the
UP
and
DOWN
keypad buttons to move the ball float
to the correct (
12.5 PPD
) reading on the metering tube.
Once the value matches the reading on the display,
press
ENTER
to accept.
8) Press
NEXT
and the SMARTVALVE will automatically
open to the third linearization point representing 50% of
the valve’s capacity. e.g.- 50% of a 50 PPD system
equals 25 PPD.
NOTE:
Follow the same procedure described in steps 6
and 7 to complete the 50% point. Then continue on to the
fourth linearization point (75%) and the fifth linearization
point (100%).
9) Once the five linearization points have been set, press
the
LAST
button four times to return the valve back to
the first point (0%).
IMPORTANT:
If the valve is not
returned to 0%, it will continue to feed gas at 100% until
you exit the Engineering Mode and reset the operation
setting from Manual (
MANL
) to Automatic (
AUTO
).
10) Once the valve is reset to 0%, the Linearization is complete.
Simply press escape (
ESC
) to accept the Linearization
settings. The
CAL VALVE
parameter is once again displayed.
Press escape (
ESC)
a second time and you will be
asked to
SAVE CHANGES?
. Press
YES
to confirm and
you will return to the Main Operating Screen. Press
MENU
, then
AUTO
to return the valve to automatic
operation.
NOTE: THE SMARTVALVE IS NOW READY FOR OPERATION.
