Electronic Temperature Switch
Series ETS 1700
APPLICATIONS
The electronic temperature switch
ETS 1700 is used together with the
temperature sensor TFP 100,
which was specifically developed
for tank mounting.
The 4 digit display can indicate
either the actual temperature, one
of the switching points, or
the maximum temperature. The
maximum temperature indicates
the highest temperature which has
occurred since the unit was
switched on or last reset.
The 4 switching outputs can be
used to control heating and
cooling processes in hydraulic
systems, as an example. All
switching and switch-back points,
which are independent of each
other, can be adjusted very simply
via a membrane keypad. For
incorporation into monitoring
systems (e.g. with PLC), an
analogue output (4 to 20 mA or
0 to 10 V) is also available.
SPECIAL FEATURES
• Temperature range 32° to 212°F
(0 to 100°C)
• 4-digit digital display in F° or C°
• Simple operation by means of
keypad programming
• 4 critical value relays, switching
points and switch-back points
can be adjusted independently
• Option for analogue output
signal (4 to 10 mA or 0 to 10 V)
• Optional mounting position
(sensor connection on the
top/bottom, keypad and display can
be turned 180˚)
ADDITIONAL FUNCTIONS
• Orientation of all switching outputs
adjustable (N/O or N/C function)
• Switch-on delay for all relays
adjustable in the range 0 to 900
seconds
• Switch-back delay for all relays
adjustable in the range 0 to 900
seconds
• Display of the actual temperature,
of a switching point or of the
peak value
ETS 1700
• Individual scale of the display range
in °F, or °C (user definable)
• Analogue output available
(4 to 20 mA or 0 to 10V)
• Programming disable to prevent
accidental or unauthorized
adjustment

Setting Options:
Setting ranges of the switching points
and/or switch-back hysteresis:
• Switching point relays 1 to 4:
• Switch-back point relays 1 to 4:
1.5 % .. 100 % FS
1 % .. 99 % FS
or alternatively
1 % .. 99 % FS
switch-back hysteresis 1 to 4:
Note: FS (Full Scale) = relative to the full measuring range

Switching point /switch-back point:
The switching point is defined as being the temperature
value, which when reached (when on the temperature rise),
causes a change in the switching direction or orientation.
This output state is maintained until the temperature falls
below the switch-back point allocated to the switching
point. The switch-back point is determined by the adjusted
hysteresis value.

When used in critical applications (e.g. strong vibrations or
knocks) the ETS 1700 must be mounted on rubber buffers
(DIN vibration mounts). When supplied, the sensor connection
is accessible from the bottom and the electrical connection
is accessible from the top. Depending on the application,
the front panel of the instrument can be turned 180˚ so that
the electrical connection can be made from underneath and
the sensor connection can be made from the top.
