It is essential that all non-operational
lamps be changed immediately to
maintain system efficiency.
temperature
safety control option*
The Temperature Safety Control consists of a heat-
sensing probe. This device protects against inadvertent
overheating inside the UV chamber, which can damage
the UV lamps and the ballast/LED Display Panel circuitry.
The Temperature Safety Control senses raised water
temperature and assumes the UV lamps are operating
“on” with no water flow.

The device automatically turns the UV lamps off when
the water temperature reaches 120º F (49ºC) and
automatically turns the UV lamps back on when the
temperature falls to 100º F (38ºC). This feature is
optional on all standard RBE models.

The device automatically turns the UV lamps “off”
when the water temperature reaches 170ºF (77ºC) and
automatically turns the UV lamps back “on” when the
temperature falls to 150ºF (66ºC).
This temperature spread prevents excessive stop/starts
during no flow conditions, and it protects the UV lamps
and the electrical components from overheating damage.
The temperature probe is located in the end plate. No
operator intervention is required other than periodic
visual verification that the UV lamps (LED Display
Panel) are properly operating during normal water flow
conditions.
* This feature is standard on all High Efficiency (HE)
units.
lamp-out alert indicator
option
Lamp Out Alert is an optional accessory package that
activates a relay when a UV lamp fails to operate.
A visual inspection of the LED UV Lamp Display
Panel will indicate which lamp has failed. Dry contacts
are provided for customer connection. The dry contacts
are rated at 3.0 Amps maximum @ 120 volts.
Wire color codes:
Green = Normally Closed
White = Common
Yellow = Normally Open
4-20 mA sensor signal
option
This option works with the optional S-254 optical
sensor. It generates a 4-20 mA output signal based upon
the relative UV intensity which may be monitored at a
remote control panel or control PC. The customer is
responsible for providing an appropriate 4-20 mA
display instrument and connecting it.
