3704-IG-001 Installation and User Manual
Page 24
Dip Switch Settings
Each Model 3704 is equipped with an 8-position dip switch on the Data Router (Figure 14), to personalize each installation.
Switch 1 allows selectable pull-in force: SW1 OFF = ~15lbs., SW1 ON (Default) = ~25lbs.
Switch 2 is not currently used and is reserved for future applications.
Switch 3 puts the EVSE into Test Mode for connecting to a Payment Module via a ZigBee network. See the 3725-UG-002
Payment Module User Guide for information about adding the 3704 to the network. OFF = Not in Test Mode; ON = In Test
Mode
Switch 4 provides an interface for Controller Access Security Systems (CASS).
Switch 5 is not currently used and is reserved for future applications.
Switch 6 puts the 3704 into learning mode to determine the initial lowering position of the J1772 cable for ADA compliance
(48 inches). When ON, press the switch on the J1772 to extend the cable to a specific position, then set the switch back to
OFF. The initial lowered position is locked into the 3704.
Switch 7 sets the amount of time the user has to engage the J1772 connector after authorization. In the case where a
Payment Module is not used and the 3704 ON button is the actuation mechanism, the default OFF setting of this switch
allows the user one minute to engage the J1772 connector in the vehicle. In the situation where authorization via a Payment
Module is required prior to the initiation of charging, the ON position for Switch 7 allows a 15 minutes timeout for the
authorization. In other words, if the J1772 plug is not engaged in 15 minutes, a new authorization must be obtained. This
allows the user time to walk from the Payment Module, which might located some distance from the 3704, to the vehicle to
plug in the connector.
Switch 8 is used to select the breaker size when two 3704s share a circuit breaker. When the switch is OFF to select an
installed 40A breaker, the maximum current delivered to each vehicle is limited to 16A. If only one vehicle is connected, it
can draw up to the full 30A. When the switch is ON to select an installed 50A breaker, the maximum current delivered to
each vehicle is limited to 20A. Again, if only one vehicle is charging, it can draw up to the full 30A.
