Example 2
If you use DIN1 as ON/OFF1 (setting 1 = default) and DIN2 as ON reverse/OFF1
(setting 2) and in addition the ESM is set to reverse the behaviour of the SED2 is
as follows:
DIN1
(ON/OFF1)
DIN4
(ON reverse/OFF1
DIN2
(ESM)
Motor Direction
0 0 0 Normal (Off)
0 0 1 Reverse
0 1 0 Reverse
0 1 1 Normal
1 0 0 Normal
1 0 1 Reverse
1 1 0 Normal or Reverse*
1 1 1 Normal or Reverse*
* Depending on which command is given first (DIN1 or DIN4).
If the digital inputs 2 (ESM) and 4 (Reverse) are active simultaneously the SED2
will run in normal direction. In this case the reverse signals cancel each other out.
