The electronic temperature switch ETS 1700 is used mainly together with the temperature probe TFP 100, which was specially developed for tank mounting.

The 4-digit display can indicate the actual temperature, one of the switch points or the maximum temperature value.

The maximum temperature indicates the highest temperature which has occurred since the unit was switched on or was last reset.

The four switching outputs can be used to control heating and cooling processes in hydraulic systems, formore

Setting Options

Setting Options

The microprocessor integrated into the ETS 1700 enables many useful extra functions in addition to the switching functions, when compared with a normal mechanical temperature switch. It is possible, for example, to activate switching delay times or to change the relay switching direction. All settings are made via the key pad.

Additional Setting Options

Additional Setting Options

  • Switching direction of the relays 1 to 4 (N/C or N/O)
  • Switch-on delay relays 1 to 4 in the range 0.00 .. 90 seconds
  • Switch-off delay relays 1 to 4 in the range 0.00 to 90 seconds
  • Switch-back mode (either switch-back point or switch-back hysteresis)
  • Display of the actual pressure, a switching point or of the peak value
  • Display filter (slow/medium/fast)
  • Display range scale individually adaptable (Fahrenheit, Celsius, user-selectable)
  • Measurement unit (Celsius, Fahrenheit) is displayed
  • Analog output (4 to 20 mA or 0 to 10 V)
  • Programming disable

Note

N/A Reverse polarity protection of the supply voltage, excess voltage, override and short circuit protection are provided.
