Running Time Indicator
The running time Indicator will illuminate when the elapsed time of the unit is
displayed on the Cycle/Hour display. Aqualogic controls are equipped with a
re-settable running time meter and are used to determine the number of hours
on the equipment and for maintenance. It is very important to record the
running time hours and lamp maintenance.
2.
Cycle and Hour Display
The digital display alternates between the number of times the lamps have
been cycled “ON” and “OFF” and the elapsed running time of the unit.
3.
Cycle Mode Indicator
The Cycle Mode Indicator will illuminate when the number of cycles is
displayed on the Cycle/Hour display. The cycle counter displays the number
of times that the lamps have been turned “OFF” and “ON”. This counter aids
in the lamp maintenance. The cycle counter is reset to zero when the running
time counter is set to zero.

. UV Lamp Operational Display
To verify the status of the UV lamps, the LED display gives the operator a
visual indication of the lamp status. When the UV lamp is “ON”, the LED will
illuminate GREEN, and when “OFF”, the indication will be RED.
6.
Lamp Operational Indicator
When all lamps are operating properly, the individual lamp LED’s will be green
and the Lamp Operational Indicator will be illuminated. During any fault
conditions, this indicator lamp will not illuminate.
7.
Low UV Intensity LED
The Detector is a sensing probe place in the treatment chamber that monitors
the relative change in lamp output through the fluid as detected by the UV
sensor at the endplate of the UV treatment chamber. As time passes, the
sensor reading will decline as the lamps age, quartz sleeves foul, temperature
changes in the fluid, or if there are changes in the fluid quality. The Low UV
Intensity LED display will illuminate when 80% of the set value has been
reached.
8.
UV Intensity and Temperature Display
The digital display will indicate the UV intensity in relative (0-100%) or
absolute (0-5000µW/cm²) mode and fluid temperature. To display
temperature, the temperature switch must be activated.
9.
High Temperature/Low Temperature Shutdown Indicator
Ultraviolet lamps produce heat. The heat within the chamber must be
dissipated to prevent damage to the UV unit and water system. Sealing
materials, gaskets, O-rings, compression nuts, lamp sockets, UV lamps and
the UV sensor can be damaged due to excessive heat. Under normal
operating conditions, the water flow is sufficient to remove the heat generated
by the lamp.
Aqualogic units have a temperature circuit mounted on the endplate or on the
inlet nozzle of the treatment chamber. When the temperature of the treatment
chamber exceeds 120°F, the UV lamps will automatically switch “OFF”,
