CHAPTER III - STARTUP
CONTROLLER STARTUP
Initial Reset
Before powering up the controller, locate the Battery Jumper
J1 on the Mother Board (Error! Reference source not
found.). Remove it, wait one minute and reinstall it. This
clears up any unwanted changes in the program and resets the
original default values.
With the front door open, verify that the CPU Fail Light on the
microprocessor, turns ON when power is applied to the unit is
turned OFF when the program is running.
Configuration Menu
U
pon startup, verify the initial setup through the
CONFIGURATION Menu 8.1 (see page 24) and adjust the
values as required. This includes adjusting the clock for
different time zones and selecting the proper language and
units system.
Alarm Buzzer
The Audible Alarm option is normally turned off until the
sensors are installed. Use Submenu 8.2.1 (page 27) to turn it
on for normal operation.
Bypass Line
By default, the Bypass Line Option is factory-set to YES to
prevent accidental feeding when there is no water flow in the
bypass line. To turn it off, set the Option to “NO” in Submenu
8.2.2 (page 27).
Battery Check
Check the condition of the Backup Battery. It prevents the loss
of memory data in case of power shutdown. The voltage of the
battery can be seen through the CONFIGURATION /
BATTERY Submenu 8.2.6 (page 28).
If the battery voltage is less than 2.5V, the battery should be
replaced with a 3V-lithium battery, Panasonic CR2330 or
equivalent.
PPM Board Initialization
T
he PC board for the PPM sensor on the PC5000 and PC7000
must be initialized prior to calibration of the PPM sensor itself.
Turn the controller on and wait at least 30 minutes to allow the
sensor to charge. Read the PPM SANITIZER display on the
controller.
Go to Initial Setup and enter Submenu 8.1.5 - Readings to
adjust the default value of the sensor readings to one (1)
second.
Adjust the potentiometer on the PPPM board marked (R14
SENS. ADJ.) to make the controller display agree with the
DPD test kit reading. Wait 10 seconds and repeat if
necessary.
After calibration is completed, remember to set the Readings
back to the default value of ten (10) seconds.
CHEMICAL CONTROL
Initial Activation of Sensors
F
or a new pool or spa, it is recommended to wait for a week or
two after filtration is started before installing the sensors. This
will prevent damage to the sensors until all the dirt and debris
have been filtered out of the water. When ready to start the
controller, install the sensors in the recirculation line and run
the recirculation pump for 30 to 60 minutes or until the
readings of the sensors stabilize.
Bypass Line Test
If there is a bypass line, open the sampling tap on the bypass
line and adjust the two shutoff valves until there is a smooth
flow of water coming out of the tap (no suction or excessive
pressure).
Water Chemistry Adjustment
B
efore starting automatic control, the water chemistry should
be adjusted to near the recommended values of 7.5 for pH and
about 1 ppm for chlorine (2 ppm for bromine). The chemicals
can be added manually or with the controller set on Manual
Mode.
NOTE: The controller will not operate in the Automatic Mode
if the sensor readings are below or above the alarm
settings.
Also, verify that the cyanuric acid level is below 40 ppm, the
Alkalinity between 80-120 ppm and the Total Dissolved Solids
(TDS) level below 1,500 ppm. If either one of these limits is
exceeded, the water is contaminated. It should be replaced
with as much fresh water as needed.
Water Sampling
Proper water sampling is essential for accurate calibration of
the pH and ORP sensors. The preferred method is to sample
the water as close as possible to the location of the sensors,
usually on the bypass line. The bypass line should be
therefore equipped with a water-sampling tap, which can be a
ball valve.
Because of the instability of chlorine, particularly under
sunlight, samples taken near the surface of the water can give
false results.
pH Calibration
N
OTE: Always calibrate the pH sensor first, i.e. before the
sanitizer.
Test the pH of the water at least twice with a fresh solution of a
standard Phenol Red test kit, or until you get consistent
readings.
The pH of the water should be near 7.4 to 7.5. If not, adjust it
manually or with manual feed control:
