Maintenance & Calibration - Delta Elektronika SM3300 Series Product Manual

MAINTENANCE & CALIBRATION
9 MAINTENANCE & CALIBRATION
9.1 GENERAL
 The SM-series power supplies do not need any maintenance
or calibration. However, care must be taken that the cooling
unit is not obstructed.
9.2 COOLING FAN
 The internal construction of the power supply is such that no
dust will reach the sensitive control circuitry, only the heat
sink in a tunnel will be cooled by forced air (see fig. 9 - 1)
 The built up of dust on the impeller of the fan and the heat
sink fins depends on the environment. It is advised to inspect
the fans and heat sinks regularly.
 Since the used fan type has an over-capacity, dust will not
present a problem very quickly.
 The thermal protection will shutdown the output in case of
overheating, so no damage will be done to the power supply.
9.3 GALVANIC INDUSTRY
 For using the power supplies in the galvanic industry it is
strongly recommended to take precautions against an
aggressive environment.
 An aggressive environment with acid, salt, etc. can harm the
electronic components. Sometimes even the copper tracks on
the printed circuit boards dissolve.
 To avoid problems, the power supplies should be mounted in
a relatively clean room, in a cabinet receiving clean air with
over pressure, or a cabinet with a heat exchanger.
9.4 CALIBRATION
 The power supplies are factory calibrated and normally need
no further calibration.
 After installation of a new or different interface, no calibration
is needed.
 Only in special situations, for example after repairing a unit,
calibration can be necessary.
 The SM3300 units can only be calibrated by software.
 Inside the unit, there are no positions with calibration
components such as trimmers or CR-resistors.
 The software calibration is performed by connecting the unit
to a TCP/IP network using the LAN connector at the rear
panel.
 Download the programming manual for Ethernet & Sequencer
via the web interface or via www.DeltaPowerSupplies.com.
