SECTION 5: MAINTENANCE
THERE ARE NO USER-SERVICEABLE PARTS INSIDE THE CAMERA. DAMAGE CAUSED BY
UNAUTHORISED MAINTENANCE OR PROCEDURES WILL INVALIDATE THE WARRANTY.
5.1 Regular Checks
• The state of the product should be checked regularly, especially the integrity of the External Power
Supply and the mains cable.
• Do not use equipment that is damaged
5.2 Annual Electrical Safety Checks
• It is advisable to check the integrity of the insulation and protective earth of the AC/DC converter on an
annual basis, e.g. U.K. PAT testing
• Do not use equipment that is damaged
5.3 Fuse Replacement
In the U.K, Ireland and some other countries, the supplied mains cable has a BS 1363 (or Type G) plug that
includes an integrated fuse. Only replace with fuse of the same type and rating for continued protection. The
characteristics of a replacement fuse are as follows:
• Rated Current: 5 A
• Rated Voltage: 240 VAC
• Size: ¼ × 1” (6.3 × 25.4 mm) cartridge
• Type: BS 1362
5.4 Zyla Chamber Design And Service Guidance
The Zyla sCMOS camera platform, like the majority of commercial sCMOS cameras on the market use a back-
lleddesigntoprotectthesensorfromcondensationduringmoderatecoolingusedtoreducedarkcurrent.In
fact,theonlycommercialsCMOScamerasonthemarketthatutilizeahardmetal-on-metalvacuumsealare
Andor’s high-end deep-cooled Sona, Marana, Neo and Balor sCMOS platforms.
Forback-lleddesigns,oneexpectsaverylow-levelofmoistureingressintothesensorchamberovertime,
pervading through the O-ring seals. These cameras utilise desiccant material in the sensor enclosure to absorb
any moisture that may enter. However, eventually the desiccant may become saturated, indicating the need for
thecamera’ssensorchambertobeserviced,whereuponthechamberwillbere-backlledandthedesiccant
replaced. Saturation of desiccant will result in condensation forming on the sensor or window when the sensor
is thermoelectrically cooled under standard operation. This will typically manifest in images from the camera
andcanappearsimilartotheeectofraindropsonawindowsuper-imposedontotheexpectedimage.If
water vapour or ice forms inside the sensor chamber when the camera is in operation, it is essential that the
camerabeturnedoimmediatelyinordernottoriskirreparabledamagetothesensor.PleasecontactAndor

IntheZylaspecicationsheetsundertheOperatingandStorageConditionsthatrelatetotemperatureand
humidity ranges, it is expected that Zyla would operate for at least 4 years and often much longer, before
chambercondensationcanbeexpectedtopresentasanissue.Andoroerastandardpre-emptiveZyla
