General Information

Analog Battery Charger (If Equipped)

The 10 Amp battery charger is an "equalize" type
charger. An "equalize" type charger will charge the
battery at its maximum output current rating until the
battery voltage reaches an "equalize" voltage and then
the charge current will decrease to maintain the battery at
a lower "float" voltage.
The 10 Amp charger incorporates fuses on both the input
AC line and the battery charger output. The input AC line
®
fuse is a Littelfuse 5 Amp, Slo-Blo
part no. 218005. The AC line fuse is located on the
charger printed-circuit board. The output DC battery fuse
is a Littelfuse 15 Amp, ATO
battery fuse is located on the charger printed-circuit
board.
The charger requires battery power to turn on. The
battery voltage must also be above a certain "boost"
voltage for the charger to turn on (also called "Under
voltage Shutdown").
The boost voltage required is approximately 11 V
a 12 V system and 22 V
the battery open-circuit voltage is less than the above
boost voltage, it is recommended the battery be checked.
If the generator's 12 V
V during normal charging operation, check the
battery. When a 12 V
battery voltage should be 13 V
If the generator's 24 V
V during normal charging operation, check the
battery. When a 24 V
battery voltage should be 26 V
The 10 Amp chargers are UL recognized for use on this
enclosure and are not to be operated outside the
enclosure.
See Specifications for more information on the analog
battery charger.

The Power Zone Pro Sync Permissive and Loadshed
Panel (P&L) controls the permissive signals and
loadshed signals sent to the ATSs (Automatic Transfer
Switches) in an MPS. The P&L monitors the generators
in the MPS to determine which are connected to the

power bus and supplying power. If the generators are
supplying enough load capacity to the bus to support the
expected load for a given permissive signal, the
permissive signal is activated which indicates to the
associated ATSs that they can safely switch their load to
the generator bus. If the generators are not supplying
enough load capacity to the bus to support the expected
load for a given permissive signal, the permissive signal
is deactivated which indicates to the associated ATSs
that they need to remove their load from the generator
bus immediately, normally with a trip to neutral position.
Further, there are Loadshed signals that operate with
basically the opposite function with the Permissives. This
is to support ATSs that have latching permissives. The
Permissives and Loadsheds operate in order of priority
so that the most critical circuits are the last circuits
deenergized and the least critical circuits are the first
circuits deenergized. The generator load capacities, the
Permissive expected loads, the Loadshed expected
loads, and the desired delays, etc. are configured
through the P&L Display based on the site requirements.
for
These configurations are done over Ethernet. The P&L
Display configures the P&L, displays information from the
P&L, and displays information from all the generators in
the system. Each P&L can be connected to up to 29
generators, supports 6 permissive signals, supports 6
loadshed signals, can relay a 2-wire start signal to the
generators, has a keyswitch to allow manual starting of
the MPS, and other features described in the P&L
manual. The P&L can also be configured through the
display on any generator in the system.

Ignition Module (If Equipped)

The Ignition Module controls the timing, duration, and
energy of the spark for each cylinder on a gaseous
engine. There is currently not a Power Zone Ignition
Module, but rather several third party ignition modules
are used based on the needs of the particular engine
configuration. Some
standalone in that there is no interface with the Main
Controller. Other ignition module types communicate with
the Main Controller over the J1939 CAN bus. These are
able to report fault conditions and other status to the
Main Controller. They are also able to receive commands
to adjust the timing, etc. from the Main Controller. The
Main Controller uses this capability to optimize the
ignition based on load, fuel type, and other conditions
while the engine is running.
