• The stainless steel temperature sensor must not be used with
aggressive media such as acids, caustic solutions or distilled wa-
ter, due to the risk of corrosion. The H 66 glass sensor should be
used in such cases.
• Only use glass encapsulated temperature sensors for electrolysis
procedures.
• Always use the extension cable H 70 when the media being
processed produces vapour. This ensures that the control unit
does not come into contact with the vapour.
• Beware of hazards due to:
- flammable materials
- combustible media with a low boiling temperature
• Do not use the device in explosive atmospheres, it is not EX-
protected.
• Danger! The user must check that all conditions have been met
for the safe and correct operation of the equipment before ope-
rating the ETS-D5 with a heater that does have a DIN 12878
compliant connector, and therefore does not provide cut-out
proection. [The cut-out protection is a mechanism that ensu-
res that the electrical heating circuit is switched off should the
contact thermometer (ETS-D5) be broken or if the connector is
removed.]
For protection of the equipment
• Protect the device and accessories from bumps and impacts.
Use of “H+P” magnetic stirring systems (no break fuse protection
included)
• When the supply current for the ETS-D5 is interrupted, the elec-
tronics for the heatable magnetic stirrer system will take over
the temperature control. This means that the magnetic stirrer
system will heat up to the temperature set (e.g. 300 °C). Read-
just the set-point temperature for the magnetic stirrer system or
switch the heating off.
Use of ”Corning” magnetic stirrer PC-400, PC-420, PC-600, PC-
620
• When using the ETS-D5 in conjunction with a “Corning” Mag-
netic Stirrer it is absolutely essential that the rotary "heat" dial on
the magnetic stirrer is set to the "O" (off) position. The ETS-D5
will only control the set temperature when it is in this position.
Warning! The heating plate temperature limiter is not active in
this operating mode.
• If the rotary "heat" dial on the magnetic stirrer is not in the "O"
position then the magnetic stirrer will heat up to the tempera-
ture set, regardless of the settings on the ETS-D5.
Warning! ETS-D5 is inactive.
The safety advices given above represent the current status of the
known risks. Nonetheless, the user must check equipment for cor-
rect and safe operation before operating any system comprising
the ETS-D5 and a magnetic stirring/heating system.
