( c o n t i n u e d )
Once all the I/O modules are installed and inter-connected via Ethernet network wiring the
system will recognize these modules and they will appear on the system set-up screen
accordingly.

Each I/O panel includes a number of I/O cards designed to provide functionality to the sys-
tem's receivers, pumps, source valves and alarms. This functionality includes input signals
(IE: from demand switches, pump overloads, etc) and output signals (IE: to pump starters,
vac valves, alarm indicators, etc). The specific functions required for each receiver, pump,
valve and alarm must be configured to specific I/O cards within each I/O panel. Once the
I/O cards are configured, specific point-to-point wiring instructions will be defined for final
connections to each of the system's pumps, receivers, valves and alarms.
U n d e r s t a n d i n g I / O W i r i n g
Since I/O cards are provided from the manufacturer pre-defined as input cards and outputs
cards, the wires coming from receivers, pumps, etc are connected to multiple cards in order
to provide the correct functionality for the device's input/output needs. A single input card
will control the input signals from multiple receivers and a single output card will control the
outputs to multiple receivers.
