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-
filled 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-filled 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-backfilled 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 effect 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 off immediately in order not to risk irreparable damage to the sensor. Please contact Andor
Product Support to arrange a Zyla chamber service.
In the Zyla specification 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 offer a standard pre-emptive Zyla
chamber service that can be used to ensure moisture effects are never experienced during usage. Please
