BARGE OVERFILL CONTROL SYS. CONNECTOR

MAX. INPUT VOLTAGE: 20.66 V DC MAX. INPUT CURRENT: 155 mA

TOTAL CONNECTED INDUCTANCE: mH

TOTAL CONNECTED CAPACITANCE: µF

NOTE: The values to be inserted for total connected inductance and capacitance apply to switches and cabling aboard the barge.

2.4.2 TERMINALS

Terminals should provide a mechanically protected, shielded, flexible cable 2 x18 AWG minimum or 4x18 AWG minimum if optional high level alarm system is used with an oil and seawater resistant jacket, terminating in a female, 5-wire, earthing-contact position 1, 16 amp connector meeting IEC 309-1/309-2. The terminal should provide cable to reach the fixed male connector at the barge manifold with sufficient excess to allow for changing draft, water depth and mooring conditions. The connector should be clearly labeled as follows:

BARGE OVERFILL CONTROL SYS. CONNECTOR

MAX. OUTPUT VOLTAGE: VDC

MAX. OUTPUT CURRENT: mA

MAX. ALLOWABLE CONNECTED INDUCTANCE: 0.6 mH

MAX. ALLOWABLE CONNECTED CAPACITANCE: 0.18 (µF)

NOTE: The values to be inserted for maximum output voltage and current apply to the

intrinsically safe associated apparatus of the terminal's overfill control panel.

2.4.3 CONNECTOR PIN ASSIGNMENTS

Pins N and T3 (L3) are reserved for optional high level alarm connection; pins S2 (L2) and RI(Ll) are reserved for emergency shutdown system connections. Pin G (unlabeled in Figure 1) should be connected to the barge cable shield or the terminal cable shield, respectively. Designations N, T, S and R are those found in the current Code of Federal Regulations. Designations shown in parentheses and on Figure 1 are those in the 1989 revision of IEC 309-2.

2.4.4 OPERATIONS

A tank barge's overfill control system should not be Used if its inductance or capacitance exceeds the terminal's design limitations or if the terminal's output voltage or current exceeds the barge's design limitations.
