Delivery Defender Lite™ (DDL-#)
The Delivery Defender Lite™ (DDL) is a universal remote overfill alarm in a compact NEMA 4X
enclosure. This unit can connect to our PROTEUS® and OEL8000II series ATG’s as well as
most industry standard Tank Gauging systems. The DDL provides delivery and alarm indication
outside, where your fuel provider can observe current tank conditions. Equipped with high
intensity sunlight visible LED indicators, high decibel horn, general alarm light, and API color
coded symbols for product identification, the DDL provides critical information to the filling
operator.
The Delivery Defender Lite™ connects using a RS-232 or RS-485 connection. There is an
optional RS-485 to RS-232 converter that is used to extend the range with the ATG if it does not
support RS-485.
** Note: “#” indicates the number of tanks. **

Block Diagram
The Delivery Defender Lite can be wired one of three ways:
1. RS-232 (appr. 75 feet)
2. RS-485 (appr. 3,000 feet)
3. RS-485 with RS-232 converter if ATG does not support RS-485
May also use one conduit for AC power and RS-485
if communication cable is rated for 600V (EC4-600V)*

RS-485 Connection
For Use Without Converter:
•Connect pins 1-3 only as shown in Figure 3.1
•Change RS-485 port settings in Proteus to RD7CTS
For Use With Converter (RS-485 to RS-232):
•RS-485 cable should be a 4-conductor twisted pair shielded cable that is at least 22 AWG
(we recommend EC-4 or Quabbin 04448).
•If only one conduit is available, use the same knockout as AC power, cable must have an
insulation rating for 600 VAC (we recommend EC-4-600V or Belden 1048A).
•Use the appropriate knockouts and cable for your site’s layout.Make your connections
as follows:
Pin 1 Tx+
Pin 2 Tx-
Pin 3 Ground
Pin 4 5 VDC (output); if using converter
The default communication settings for the Delivery Defender Lite™ are: 9600 baud, 8 data
bits, no parity, 1 stop bit for both RS-485 and RS-232. Check jumper settings on J4 (see Fig. 3.2).

RS-485 Connection (cont.)
The RS-485 to RS-232 converter has the following pinout:
Pin 1 Tx+
Pin 2 Tx-
Pin 3 Ground
Pin 4 5 VDC (input)
You must also use the supplied 120-ohm termination resistor to terminate the COMM line
between Tx+ and Tx-. The RS-232 wiring (supplied 10ft DB-9 cable) can be reconfigured for any
ATG by swapping the Tx and Rx wires (shown in Figure 4.0).If you do not need to use the
converter, connect only Pins 1-3 from the DDL.
** Converter sold separately **

Swapping Communication Type to RS-232
The RS-485 wire (green, black, white) is connected to J6 of the main board of the DDL.
Swapping this cable for the RS-232 cable (white, black, red) will change the configuration to RS-
232. Change the jumper setting on J4 (see Figure 5.2). The RS-232 pinout on the bottom left of
the enclosure is as follows (see Figure 5.1):
Pin 1 RS-232 Tx
Pin 2 RS-232 Ground
Pin 3 RS-232 Rx
** Note: Swapping the Tx and Rx wires will create a null modem connection. **
** RS-232 has a limited distance of approximately 75 feet. **
** Check jumper setting on J4 (see Fig. 5.2). **

NOTE: Each site should be assessed and programmed accordingly.
•Set each tank Overfill Alarm to 90%.
•Set each tank High Product Alarm to 90%.
•Set Drop Threshold value to a reasonable level corresponding to each tank’s capacity.
Recommended value is 50 gallons.

delay.
** Note: To be taken as recommendation only. Program each tank to site’s specifications.
