How does the SGR Sensor, MDGF module work with Micrologic X?

For the below systems as described in the MDGF instruction sheet

Please find below how the current sensor, MDGF works with Micrologic :

If a primary current of 100A passes through the SGR current sensors, then a secondary current of 0.1A will be received by the MDGF summing module via terminals 1(J1-1) and 3(J1-3).

The MDGF summing module internally does the following calculation :

100A(rms)*0.00173 = 0.173V(rms) : this voltage can be measured on the terminal 5(J2-2) and 7(J3-1) of the MDGF summing module and it is transmitted to the terminals M2 and M3 of the micrologic Trip Unit.

The Micrologic does the following calculation : 0.173V(rms)/0.00173(rms) = 100A

The Micrologic will report the Ig trip if the current from the current sensor and MDGF exceeds the Ig threshold and the tg time delay expires
