Load Management Inputs:
If the unit has been configured for Off-Peak Charging, the Green
CHARGING light may blink after plugging the cable in, and the
contactor may not close. This means that a timer, or other device,
has been connected to the Load Management input, and charging
will not occur until a specified time, possibly later in the evening
when electrical rates are better. To override this feature and begin
charging immediately, push the Start/Stop button.
Pressing the Start/Stop button will alternately Stop and Re-Start
charging. The button will not initiate charging unless the cable is
connected, and the vehicle requests a charge.
There are two Load Management inputs, labeled High/Low
and High/Off, on a terminal block as shown in
Figure 8
below.
Grounding High/Off will completely inhibit charging until it is
released. Grounding High/Low will tell the CS 3-Phase to send
a signal to the vehicle instructing it not to charge, but instead to
draw only a minimum amount of current for auxiliary uses such as
cooling down the battery pack, or pre-heating the cab in the early
morning.
Figure 8. Four-Position Terminal Block
Relay Output:
The two terminals labeled Relay 1 & 2 are dry contacts that are
normally open. If the Protection light comes on, or if other internal
problem is sensed by the CS 3-Phase’s computer, these contacts
will close. This can be used to power a remote indicator to warn
the user that a problem exists, giving them the opportunity to
correct the problem and help ensure the vehicle will be charged
when needed.
