potentiometers to adjust the UV alarms and
set
points.
Controller
setting
and
adjustments are now completed thru
software. We have also added password
protection to eliminate adjustment by
unauthorized personnel.

1 Wiring
Prior to working on the electrical panel, all electrical power must be removed and isolated from the
system. Please note that there maybe additional electrical power connected to the system if there are
customer interface wire connected to the alarm contacts from the Low UV sensor or High Temperature
alarm.

AC power wires
Detector input connections
High temperature relay alarm(s)
Low UV relay alarm(s)
Analog signal 4-20mA and 0-1VDC
1. Wiring AC power wires
The existing H-N-G wires should be removed from the existing terminal to the Ac input of the new
Monitoring Station. There is no voltage selector switch on rev 2.
2. Wiring the detector input connection
The existing 6 wires should be removed from the existing terminal to the detector input of the new
Monitoring Station.
3. Wiring the high temperature relay alarm
The existing wires to the COM-NC and NO should be removed from the existing terminal to
temperature input of the new Monitoring Station. Please not that there are two sets of relay contacts (1
and 2). The wiring from the existing set of contacts should be noted before removing the wires and
reconnecting.
4. Wiring the low UV relay alarm
The Low UV relays are generally connected to customer interface wiring. The existing wires if any
should be removed and reinstalled to the Low UV input of the Monitoring station.
5. Wiring the Analog signal 4-20mA and 0-1VDC
Any analog connects should be remove and re terminated.
2. SETUP AND OPERATING INSTRUCTIONS
PICTURE #1 – The front face plate of the UV Monitor Station
Lighted LCD Display
Indicates 2 lines of information
Up & Down Arrows provide
selection of options
“ENTER” button for access to
“MAIN MENU” and to select
options
A) Operation
The Monitoring station is a combination UV and temperature controller. The signals from the
detector are displaying the UV intensity and water temperature. Each of values may have a
corresponding alarm set point.
The first line of the main menu display indicates the UV intensity in relative or absolute units.
The second line indicates water temperature in F or C.
Main display

Alarm display
The first line of the alarm display indicates the relative UV intensity alarm set point. The
second line indicates temperature alarm set point. This display is accessed by pressing the up
arrow when in the main display.
B) Software set up procedure will require accessing the main menu. This process is started by
depressing the “ENTER” button, (described in picture #1), and then entering the password.
1.) The password 1234 is entered by:
a) Depressing the up arrow will cycle to each digit.
b) When the digit is achieved – Depress the down arrow to move to the
next digit position.
c) Repeat procedure until all four digits indicate the correct password.
d) Then depress enter
e) The Display will indicate “MAIN MENU”
C) From the “MAIN MENU” the following parameters can be accessed. To modify or change
these parameters follow the steps described in paragraph ‘D’
1) The UV intensity display, (“UV DISPLAY”)
a) RELATIVE
– Display of relative intensity 0-100%
b) ABSOLUTE
– Display absolute intensity 0-5000 µw/cm²
2) The UV intensity alarm set point (“UV ALARM”)
a) ON (set point)
– To enable UV alarm (DEFAULT)
b) EDIT
–Select UV alarm set point 20-90%
c) OFF
–disable UV alarm
3) Setting the UV 100% value, (“UV 100% LEVEL”)
a) DIRECT
– Sets 100% UV (current value of absolute intensity)
b) EDIT
– Sets 100% to entered absolute intensity value
4) The temperature display, (“TEMP DISPLAY”)
a) FAHRENHEIT - select temperature unit of measurement
b) CELCIUS

D) The following steps will specify how to set each parameter of the monitoring station. After a
parameter is set, the operator will be instructed to select “RETURN” once or twice to return to
the operating screen. The operating screen will have the UV intensity displayed on the first
line, and the temperature displayed on the second line.
1a) Setting the UV intensity display (Absolute µw/cm²or Relative %) :
i. The main menu is accessed per the steps in paragraph ‘B’
ii. The Display will indicate “MAIN MENU”
iii. Use up / down arrows to scroll to “UV DISPLAY” in the sub-menu –
“ENTER”

“ABSOLUTE” as indicated – “ENTER”
v. The display will indicate “MAIN MENU” with sub menu indicating “UV
DISPLAY”.
vi. Use up / down arrows to scroll to “RETURN” – “ENTER”
vii. The display should be at the main operating screen indicating UV intensity
and temperature
2a) Setting the Low UV Alarm Set point:
The alarm point will be a number between 20-90%. The selection is typically
based upon the lamp type and operating conditions. Typical alarm set point
values for equipment: with HX lamps 80% and standard lamps 60%.
i.
ii.
iii.
iv.
Follow the procedure in paragraph ‘B’ to enter the “MAIN MENU”.
Use up / down arrows to scroll to “UV ALARM” – “ENTER”.
Use up / down arrows to scroll to “EDIT” – “ENTER”
Use up down arrows to scroll to preferred UV alarm threshold percentage
– “ENTER”.
v. Verify main menu line indicates “UV ALARM” and the sub menu indicates
“ON( XX %)”
Note the ‘XX’ indicates selected value
vi. Use up / down arrows to scroll to “RETURN” – “ENTER”.
vii. Then again scroll to “RETURN” – “ENTER”.
viii. The display should be at the main operating screen indicating UV intensity
and temperature
3a) Setting the 100% UV:
Typically the UV Monitoring station intensity is set to 100% UV when new
lamps and quartz sleeves have been installed and the system is operating
under “normal operating conditions” (flow, temperature and water quality).

vi. The display should be at the main operating screen indicating UV intensity
and temperature
5a) To set temperature alarm set point:
The temperature alarm point is normally set to 120F. High temperature
units are special equipment in which the set pint is 170F. If the temperature
alarm is set to off, this will disable the temperature control feature and
damage to the unit can occur.
i. Follow the procedure in paragraph ‘B’ to enter the “MAIN MENU”.
ii. Use up / down arrows to scroll to “TEMP ALARM” – “ENTER”.
iii. Use up / down arrows to scroll to 120F (default) , 170F or off – “ENTER”
iv. Verify display indicates main menu indicates “MAIN MENU”, and the sub
menu indicates “TEMP ALARM”.
v. Use up / down arrows to scroll to “RETURN” – “ENTER”.
vi. Then again scroll to “RETURN” – “ENTER”.
vii. The display should be at the main operating screen indicating UV intensity
and temperature
E) Alarm Indications
1) “Low UV Alarm”
a) The UV alarm is activated when the detector UV measurement falls below the
low UV alarm set point. Once activated, the controller will actuate the
following
a. There will be an audio alarm once every second for 30 seconds
Page 8 of 9
b. The LCD screen flashes blue. The screen will remain flashing BLUE
until the UV Intensity level adjusts above the threshold or the alarm is
disabled
c. The low UV output relays will change state
2) “HIGH TEMP ALARM”
a) The high temperature alarm is activated when the detector senses a
temperature above the high temperature set point. Once activated the
controller will actuate the following
a. There will be an audio alarm once every second for 30 seconds.
b. The LCD screen flashes RED. The screen will remain flashing RED
until the temperature alarm is corrected.
