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
connection (next to the terminal strip).
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.
