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-

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
