CONNECTION DIAGRAM
ENDA ETS762 is intended for installation in control panels. Make sure that the device is used only for intended
purpose. The shielding must be grounded on the instrument side. During an installation, all of the cables that are
connected to the device must be free of energy. The device must be protected against inadmissible humidity,
vibrations, severe soiling and make sure that the operation temperature is not exceeded. All input and output
lines that are not connected to the supply network must be laid out as shielded and twisted cables. These cables
should not be close to the power cables or components. The installation and electrical connections must be
carried on by a qualified staff and must be according to the relevant locally applicable regulations.
(3) State indicators shows the state of the device.
(7) Used for selecting run or programming modes or for adjusting parameters.
(4) Used for adjusting the preset values in the run mode.
Increment or parameter selection key during programming mode.
(5) Decrement or reset key in the run mode.
Decrement or parameter selection key during programming mode
(6) Used for selecting preset1, preset2 or user defined message in the run mode.
Used for selecting oPtion. s or parameter to be changed in the programming mode.
(2)

out1 pulse time can be adjusted between 0.1 and 999.9s .
If it is adjusted to 0.0, out1 is energized continuously when

out2 pulse time can be adjusted between 0.1 and 999.9s .
If it is adjusted to 0.0, out2 is energized continuously when

A time delay between 0.0 and 999.9s can be included to the
operation of out1. If process value do not stay over prset1
value for a time interval less than time delay, out1 will not be
