ETS 1700

User Manual

Issue date 28.02.00

1. Functions of the ETS 1700

• Display of the current temperature in °C or °F or in a scale defined by the user.

• Switches the 4 relay outputs according to the temperature and the pre-set switching points

and hystereses or switch-back points.

• Records the maximum temperature since the unit was switched on.

• Menu for basic setting (adaptation of the ETS 1700 to the particular application).

• Two different types of programming enable.

2. Mounting

The ETS 1700 is mounted via the 4 mounting holes in the rear panel of the housing. In critical
applications (e. g. strong vibrations or knocks), the ETS 1700 must be mounted on rubber
buffers (DIN vibration mounts). A mounting kit is available on request (see Point 14.2 "Other
Accessories").
When supplied the connection for the temperature sensor TFP 100 is accessible from the
bottom and the electrical connection is accessible from the top. The front panel can be turned
through 180°, so that the electrical connection can be made from underneath and the connection
for the temperature sensor can be made from the top (see Point 10 "Changing the mounting
position”).
The electrical connection must be carried out by a qualified electrician according to the relevant
regulations of the country concerned (VDE 0100 in Germany).
When connecting the temperature sensor TFP 100 and the analogue output, screened lines
must always be used (e.g. LIYCY 4 x 0.5 mm²). The temperature sensor housing must be
earthed via the

Additional assembly notes which have been shown to reduce the effect of electromagnetic
interference:

• Make line connections as short as possible.

• Use screened lines.

• The cable screening must be fitted by qualified personnel subject to the ambient conditions

and with the aim of suppressing interference.

• Direct proximity to connecting lines of user units or electrical or electronic units causing
interference must be avoided as far as possible.

connection (next to the terminal strip).

3. Pin connections

3.1 Sensor connection

A screened connection line and a 5-pole connector are supplied with the ETS 1700. The
appropriate 4-pole connector (ZBE 03) is supplied with the TFP 100. These must be connected
in accordance with the following pin connection and wiring diagrams.

5. Digital display

After switching on the supply voltage, the unit briefly displays ”ETS” and then displays the
current temperature.

2 s

Notes:

• In the basic settings the display can be altered so that, once switched on, the unit displays a
switching point or the maximum value permanently. In this case ”S.P. 1”, ”S.P. 2”, ”S.P. 3”,
”S.P. 4”, or ”MAX” appears briefly on the display following the switch-on message. The
current temperature can be displayed briefly by pressing the ”+” or ”-” key.

• If the current temperature exceeds the nominal temperature of the unit, it can no longer be
displayed and the display begins to flash.

• If the current temperature is below 0.5 °C, then 0 is displayed.

6. Output function

6.1 Relay outputs

The ETS 1700 has 4 relay outputs. One switching point and one switch-back point and/or one
hysteresis can be set for each relay. The appropriate relay pulls in when the pre-set switching
point is reached and drops back when the temperature falls below the switch-back point.

Whether the unit operates with adjustable hystereses or adjustable switch-back points is
determined via the ”switch-back mode”, in the basic settings (see Point 8).

Switch-back mode is set to "hysteresis":
The pre-set hysteresis determines the switch-back point (switch-back point = switching point

minus hysteresis).
Switch-back mode is set to ”switch-back point”:
The switch-back point is set directly.

Abbreviations: "S.P.1" .. "S.P.4" = switching points 1..4

"HYS.1" .. "HYS.4" = hystereses 1..4
"r.S.P.1" .. "r.S.P.4" = switch-back points 1..4

6.2 Analogue output

Analogue output signal 4..20 mA or 0..10 V (adjustable in the "Basic setting" menu)

6.3 Setting the switching points and switch-back points / hystereses

• Press appropriate key

• Switching point/switch-back point/hysteresis number is displayed e.g. "S.P. 1"

• After 2 seconds the current setting flashes.

• Using the "+" and "-" keys, alter the setting.

• After 3 seconds the display switches back..

increments.

• If a setting has been altered, ”PROG” appears briefly in the display when the display switches
over. The new setting is then saved in the unit.

2s.
Or:

returns to normal display mode after 2s.

Notes:

• If ”HIDE” is displayed instead of ”MENU”, the menu can only be called up if the keys are held
down when the supply voltage is switched on (see Point 8.2 ”Summary of basic settings,
Hidden basic setting menu”)

• When changing the display range, the switching point and hysteresis or switch-back point
settings are converted automatically. This can cause minor rounding errors.

• If after 50 seconds no keys have been pressed, the menu automatically closes down. Any
changes which may have been made will not be saved.

9. Programming enable

The unit has 2 types of programming enable which must both be set to ”ON” to change the
settings. The software programming enable can be set or removed during operation. It provides
protection from unintentional alteration. A programming disable via the hardware programming
enable means 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.

11. 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:

ER.01 The switching points and hystereses/switch-back points are not within the

permissible setting range.

Corrective
action: Correct the settings.

ER.10 A data error has been detected in the saved settings. Possible causes are strong

electromagnetic interference or a component fault.

Corrective
action: Check all the settings (programming enable, switching points, switch-back points

and basic settings) and correct these if necessary. If the error occurs frequently,
please contact our Customer Service Department.

ER.12 An error has been detected in the stored calibration data. Possible causes are

strong electromagnetic interference or a component fault.

Corrective
action: After acknowledging the error, the unit will continue to operate, with reduced

accuracy, until it is switched off. However, check all important settings (switching
points, switch-back points and basic settings) and correct these if necessary. The
unit must in any case be returned to the manufacturer for re-calibration or repair.

An error has been detected in the stored calibration data. Possible causes are
strong electromagnetic interference or a component fault.

Corrective
action: Check the supply voltage to the ETS 1700
