External Error Indication; Maintenance Current - ClipperCreek CS-40 User Manual

CS-40 User's Manual
Note: The vehicle does not need the owners attention after a power outage.
The CS-40 will automatically resume charging when power is
restored.
External Error Indication: Whenever the Red PROTECTION light is lit, a
relay on the board will provide a contact closure that can be used to
remotely indicate that a problem exists. A fleet vehicle yard, for example,
could use this feature to light a lamp or ring a bell in the main office, letting
them know immediately that a vehicle has a charging problem. This early
warning helps assure that each vehicle will be properly charged and ready
for use when needed.
Maintenance Current: If the unit is set up for Off-Peak Charging as de-
scribed above, normal charging current cannot be drawn by the vehicle until
the Off-Peak hours. However, the CS-40 can be set up to allow a minimum
amount of current while waiting for the timer to allow full-rate charging. This
is known as Maintenance Current, used for all power needs on the vehicle
except charging the main battery pack. An example would be preheating the
cab, or keeping the auxiliary battery topped off. As in the Off-Peak mode
above, the Green CHARGING light will flash if the vehicle is connected and
waiting for the timer to allow charging. The contactor will close immediately
to supply this small amount of power, but the main battery pack will not be
allowed to charge.
The Maintenance Current feature can be selected by connecting the Timer's
control wire to the High/Low pin on the 4-terminal Terminal Block. Connect-
ing to the High/Off pin will remove all power from the vehicle until the Off-
Peak Charging time arrives. The correct pin can easily be identified by
looking at the wiring diagram for the CS-40 on page 11. The other two pins
on the terminal block are the relay contacts for the External Indicator.
In summary, making the best use of the Maintenance Current feature will
require the following:
1. Installation of a Time-Of-Use meter by the electric utility.
2. Installation of a clock/timer to allow the CS-40 to charge only during
Off-Peak hours.
3. Connecting the timer's control wire to the High/Low pin on the
Terminal Block.
