for overload tripping before commissioning the motor starter
EM 300 EDS/ERS. The setting is made with 2 rotary encoder switches with 8 or
10 switch positions (see figure on page 1-3). The set value in each case is deri-
ved from the sum of the two set values.
Set values
The set values together with their position on the rotary encoder switch are
given in the table below
.
Example
If you want to set a current of 1.28 A, turn switch 1 to position 3 and switch 2 to
position 4.
