Remote Reset Input
The remote reset input allows the operator to reset the accumulated volume on the MC-III Panel Mount to
zero with a switch or a pulse. This input is optically isolated. The input is shown connected in two ways, with
a power supply and switch in a remote location (Figure 2.5), and with a pulse generator in a remote location
(Figure 2.6).
The reset input or reset pulse must be active for 3 seconds to clear the total.
