Cleaning Windowed Enclosures and Detectors
Optical windows on the Model SS2 Detector should be cleaned periodically
according to a regular maintenance schedule. For clean area applications,
perhaps monthly basis will be sufficient. For extremely contaminated
application environments, such as truck filling stations with presence of
black carboneous smoke, daily cleaning schedule may be necessary.
Clean the window of the Model SS2 Detectors each time they are handled,
the windows appear contaminated, or the Detector fails an end-to-end test
with a Handheld Tester.
Clean the Detector Module's Sensor each time Detectors have been
disassembled for wiring or replacement.
Use a blast of an air hose or an oil-free cloth to clean the enclosure
window. Oil degrades the performance of UV Detectors. Occasionally, the
use of a solvent, such as alcohol is acceptable. No disassembly of the
Model SS2 Detector is required.
DO NOT USE SILICONE-BASED OR COMMERCIAL
WINDOW CLEANING PRODUCTS. THEY WILL
DEGRADE THE MODEL SS2 DETECTOR
PERFORMANCE.
WARNING: Potential electrostatic hazard. Do not rub with dry cloth.
SS2-A, -AN, -AH, and –AM Detectors' Faults
Model SS2 Detectors will indicate a Fault (or Trouble) condition by de-energizing
its Fault Relay (J2 connector). The following are Detector Faults:
a. Temperature Fault: The Detector will Fault if the internal
temperature during operation is above 85°C or below -40°C.
Requires factory re-certification to correct. (Both LED's blink
rapidly.)
b. Relay Fault: The Detector will Fault if one of its Relay circuit fails. (One
LED is on until the fault is corrected.) Return to factory for service.
a. Excessive Input Voltage Fault: The Detector will Fault if the
voltage supplied to it is too high. Requires factory re-
certification to correct. (Both LED's blink rapidly.)
c. No Power Fault: The Detector will Fault if the voltage supplied to it
is interrupted or turned off. (No LED indication.)
d. Self-Checking Fault: The Detector will fault if its internal
microcomputer self-checking circuitry and software finds a failure.
