WIRING ECHOPOD
®
After mounting the sensor, make the necessary electrical connections. A wiring diagram with specific
recommendations for the sensor’s configuration can be printed from the WebCal
®
program. A typical wiring
diagram is shown on the next page.
Red & Black:
Red (Power) and Black (Return) leads are for connection to a 24 VDC power supply or to a 4-
20 mA loop power source. The Red and Black wires can be extended up to 1,000 feet using a 22-gauge or
larger wire; however do not extend the green and white wires beyond 15’.
White & Green:
White (TX) and Green (RX) leads are reserved for use with WebCal
®
and PodView
®
communication and should not be connected during usage in the application. These wires should not be
connected to WebCal
®
while power is supplied from any source other than the LI99 series Fob. The maximum
cable distance between the computer and EchoPod
®
is 15’.
Note:
Never allow the white or green wires to
touch any power supply.
Blue, Orange, Yellow & Purple:
Blue (Rly1), Orange (Rly2), Yellow (Rly3) & Purple (Rly) wires are the relay
contacts (normally open) from each of the relays respectively.
Brown:
The Brown wire (RLY Common) is the common for all the relays. Relay selection is determined by
the configuration in WebCal
®
.
Note:
EchoPod
®
uses latching relays. When power is removed to the sensor, the relays will remain in
their last state. For example, if the relay is energized when power is removed, the relay will
remain in the energized state.
