Electronic Temperature Switch ETS 300 User manual Date of issue: 03.12.
1. Functions of the ETS 300 The ETS 300 is available with a built-in and with a separate temperature sensor. Depending on the model, the unit offers the following functions: · Display of the actual temperature, maximum value or a switching point. · Switching the switching outputs according to the temperature and the pre-set switching parameters.
4. Digital display After switching on the supply voltage, the unit briefly displays “ETS” and then displays the actual temperature. 2s In the basic settings the display can be altered. For example, the maximum value can be permanently displayed. This is the highest temperature which has been recorded since the unit was switched on or was last re-set. A switching point can likewise be permanently displayed or the display can be set to be dark. Depending on the setting, "TOP", "S.P. 1", "S.P.
5. Output function 5.1 Switching outputs The ETS 300 has 1 or 2 switching outputs. The following settings can be made under the basic setting: 5.1.1 Switching point setting (SP) One switching point and one hysteresis can be set for each switching output. The respective output switches when the pre-set switching point is reached and switches back when the temperature falls below the switch-back point.
.3. Setting the switching points, hystereses and/or critical values for the window function · Press "mode" key · "S.P.1" or "hi.1" is displayed · Keep pressing the "mode" key until the required parameter is displayed (depending on the basic setting: "S.P.1", "hY.1", "S.P.2", "hY.2", "hi.1", "Lo.1", "hi.2" or "Lo.2"). · After 2 seconds the actual setting flashes. · Use the or the keys to alter the setting.
Separate sensor - 30 .. 150 °C (-22 .. 302 °F) -27 .. 150 °C (-16 .. 302 °F) 1 .. 178 °C (2 .. 320 °F) 1 °C (2 °F) * All ranges given in the table are adjustable by the increments shown. 6. Basic settings In order to adapt the unit to a particular application, the function of the ETS 300 can be altered via several basic settings. These are combined in one menu. 6.1 Altering the basic settings Important note: when the menu is activated no switching operations are carried out.
6.2 Summary of the basic settings Setting Display Switching mode switching output 1 (Sm 1) Setting range SP/ Win Presetting SP ON/ OFF ON 0 ..750s 0 0 ..750s 0 ACT/ Top/ S.P.1/ S.P.2/ OFF ACT YES/ NO NO Switching output 1 operates in switching point / hysteresis function Switching output 1 operates in window function Switching direction switching output 1 (S 1) “ON”: normally open function. “OFF”: normally closed function.
7. Programming enable The unit has 2 types of programming enable which must both be set to "ON" to change the settings. The operating programming enable can be set or removed during operation. It provides protection from unintentional alteration. A programming disable via the main programming enable has the effect that no change to the settings can be carried out during operation. This serves, for example, as a safety function or as protection against unauthorised alterations. 7.
8. Error messages If an error is detected, then a corresponding error message appears which must be acknowledged by pressing any key. Possible error messages are as follows: E.01 The switching points and hystereses have been set in such a way that the resulting switch-back point is no longer within the permissible setting range. Example: Switching point is set to 65 °C, the hysteresis to 100 °C.
