Elements to identify in the back area of the Monitoring Station
are:
See Fig. B
1. Temp alarm settings switch
2. 0-1V UV output terminal block
3. 4-20 mA output terminal block
4. UV relay terminal block
5. Power input terminal block
6. 230V / 115V voltage selector
7. Temperature relay terminal block
8. Temperature output (ºC / ºF) switch
9. Sensor input terminal block
Detector:
The Detector is a combination temperature and UV probe. A state-of-the-art
GaN photodiode and semiconductor temperature sensor is uniquely
packaged into a hermetically sealed stainless steel housing. The assembly
of the unit is done under dry nitrogen gas to eliminate the presence of
oxygen and water. The semiconductor sensor signals are then processed
within the sensor and sent via the cable into the Monitoring Station. Do not
attempt to remove any of the screws that seal these ports. By doing so, you
may damage the Detector and will void the warranty and the optional NIST-
traceable calibration certification (if included).
See page 12 for sample
certificate.
The Detector is provided with an O-ring. This O-ring is necessary
to create the proper seal when the unit is installed in the Aquafine
®
UV
treatment chamber. Be sure that the O-ring is present when installing the
Detector in the UV treatment chamber.
Cable:
The cable provided with the Detector interconnects the Detector with the
Monitoring Station. On one end it has an IP-65 grade connector that is
connected to the Detector after it is installed in the UV chamber.
