3.16.4 MX4428 PROGRAMMING OPTIONS - MIM800 / MIM801
The mode sets the operating configuration.
For the MIM800 the default value of 4 selects normally open operation with no interrupt. A
mode of 6 selects normally open with interrupt on alarm. Changing parameter 2 to 176
enables short circuit fault detection. Setting the mode to 5 enables normally closed
operation.
