Note: Emitter and receiver power (current) requirements are accounted for. The above values represent
additional current draw that must be accounted for because of the load current.
Note: Maximum cordset lengths are intended to ensure that adequate power is available to the EZ-
SCREEN LS when the supply is operating at +20 V dc. Values in the previous table are worse case.
Contact banner Engineering if there are any questions.
Note: The length of Emitter machine interface cordsets can be two times longer than those listed for the
receiver in the table above if a CSB Splitter cordset is not used. If a CSB Splitter cordset is used, connect
one branch of the CSB splitter to the receiver and other branch to the emitter via DEE2R double-ended
cordset up to the same length listed in the table above.
Of the standard DELS-11..E interconnect cordsets, all cascade installations (2, 3, or 4 pairs) can use up to a 15.3 m (50.2 ft)
DELS-1150E cordset to connect the sensor pairs (L2, L3, and L4), except for the following situations (refer to the following
table).
Because of the large number of possible combinations, the table for four cascaded light screens cordset options includes
only applications in which L2 = L4. A common installation is one that protects two areas of a machine, for example, the
front and back of a power press, and uses four EZ-SCREEN LS pairs to create two L-shaped sensing fields.
