4.4.11 Power and Connectivity Usage Recommendations
Recommended Specification (order
code in brackets)
Power Usage
Engine
State
Donor Vehicle Battery(s)
LOW CONTINUOUS POWER TAKE OFF - Up to
additional 5mA at Key OFF, for example: KL30 fed
small current peripheral chargers.
Engine
OFF
Loads
Twin Batteries of same type (only standard
on certain applications)
MID CONTINUOUS POWER TAKE OFF - Between
5mA and 30mA at Key OFF, for example:
Trackers(with sleep function, no GPS), Control
Gear, KL30 fed medium current peripheral char-
gers.
2 High Performance Deep Cycle AGM
batteries (OW5)
HIGH CONTINUOUS POWER TAKE OFF - Between
30mA and 180mA at Key OFF, for example:
Trackers with GPS, Control Gear, KL30 fed high
current peripheral chargers DO NOT EXCEED
180mA.
2 High Performance Deep Cycle AGM
batteries (OW5) + Ford Programmable
Battery Guard -max 175A* (A540). Addi-
tional batteries maybe required, for further
information see Battery Configuration,
Additional Loads, Start-Stop and SRC, in
this section.
OCCASIONAL SHORT TERM HIGH POWER TAKE
OFF - 40-240A at Key OFF, for example: Cranes,
Tippers, Tail Lifts, 230V Inverters, Ambulances.
Donor Vehicle Alternator
LOW CONTINUOUS POWER TAKE OFF - Up to
30A, for example: Maintenance Van with water
heater and additional lighting but no further
systems.
Engine
RUN
Loads
Up rated 240A Extra Heavy Duty Alternator
AND/OR RPM Speed Control (A003) to
improve Alternator Output at idle if
required. For further information see
Battery Configuration, Additional Loads,
Start-Stop and SRC in this section and
Charging Systems to configure charge
mode.
HIGH CONTINUOUS POWER TAKE OFF - 30A -
240A, for example: Ambulance, High Load Main-
tenance Vehicle, Refrigeration. DO NOT ALLOW
BATTERY DISCHARGE AND DO NOT ALLOW
SYSTEM TO DROP BELOW 13V, for further
information see Battery Configuration, Additional
Loads, Start-Stop and SRC, in this section.
RPM Speed Control (A003)
Power Take Off applications which require elev-
ated idle engine speeds, for example: Mobile Tire
Filter Van, Welders Vehicle, Mechanical PTO from
engine.
High Power Pack Option (A550) and
Supplemental Batteries and Supplemental
Energy Source pending charge balance
calculation, see Battery and Cables section
For application where the Customer Loads
requirement exceed HIGH CONTINUOUS POWER
TAKE OFF, for example: total Ford and Converter
loads exceed the highest available Ford alternator
rating
NOTE:
The Ford Programmable Battery Guard
(A540)) can be stand alone or bought within the
HIGH Power Converter Pack (A550). The system
is an Intelligent PATENTED battery guard for
Power Take Off requirements that has features
including preserving enough energy to crank even
with engine off power requirements, charge the
entire battery system from a mains charger,
charge third party batteries from engine run,
preserve leisure batteries from too many crank
cycles and helps maximize fuel save, reducing
emissions, charging requirements by efficiently
disconnecting third party loads that are not
required. There are further features to warn from
disconnect and override controls. Full details of
the system can be found in this Battery and
Cables section.
