To set the filtering time, proceed as follows:
1. Remove the side covers from the module circuit board by
removing the four screws securing the covers to the module and
remove the circuit board.
2. Position the jumpers as required to provide the filter time you
require (see below). Use your fingers to pull the jumper up and
position over the 2 pins corresponding to your selection (Fast or
Norm).

3. Reinstall the covers on the module circuit board and secure with 4
screws.
