External Shunt Adaptor (PLS2)
Up to two external shunts can be added to the
PL to allow it to measure larger currents than it is
capable of measuring directly. The shunt adaptor
measures the current in a shunt (eg SH200),
converts it to digital information and sends that
information back to the PL. The connection to the
shunt is DC isolated from the PL so the shunt can
be placed in any part of the circuit. Currents up to
250A can be measured. See the PLS2 instruction
sheet for more information.
External Battery Temperature Sensor (PLT or
PLTB)
The PLT is a plastic-cased unit for direct attachment
to the battery wall. The PLTB has a bolt-on lug
for attaching to either battery terminal. The unit
connects to the T+ and T- inputs on the green
terminal block under the PL cover. See Section
7.4.3 for further details.
Computer/Modem Serial Interface (PLI)
An RS232 level serial interface is available
which allows the PL to communicate with a
computer or be remote accessed via a modem.
This is a quick way to load settings into the PL
or extract performance data. All of the data
is remotely accessible, and all settings can be
adjusted. Software (PLCOM) is available for
IBM compatibles to make this easy. Data can
be cut and pasted into a spreadsheet or other
applications.
PLCOM Software
PLCOM allows a computer to communicate with,
and control the PL series charge controllers.
PLCOM requires an IBM compatible computer
running Windows 95 or later. A suitable modem
is required for remote communication over a
telephone or radio network.
Remote Display (PLM)
The PL charge controller can be accessed from up
to 100m away using a wired remote display. All of
the functions work in the same way as on the actual
controller. Includes built-in audible alarm and display
backlighting.
The PLM can be used to look at the PL screen in a
more convenient or second location.
E.g. When you would like to check system
information inside your house or motor home, and
do not want to go outside to the shed or battery box
to see information recorded on the PL.
Synchronisation / Alarm Unit (PLA)
The PLA allows synchronisation of up to three(3)
PL charge controllers for charging a single battery
from multiple arrays. It also provides 4 additional
programmable alarm relay outputs and RS232 port
for communication with PLCOM software. Can give
totals of data collected from all connected PL charge
controllers.
Cables (WYS, WZS, WXS, PLJ, Double
Adapter)
New
shielded
data communication cables and
adapters that allow ‘daisy chain’ connection of the PL
charge controller to accessories (replaces the older
WY and WZ cables).
WYS: 3m cable for connection between PL20/40
and the first accessory.
WZS: 3m cable for connection between PL60/80
and the first accessory.
WXS: 3m cable (custom lengths available) for
connection between PL accessories or as an
extension cable for WYS/WZS cables.
PLJ: In-line joiner for connecting WXS cable as an
extension.
Double Adapter: 2 female to 1 male adapter which
is plugged into an accessory and used with the WXS
cable to connect another accessory.
WARNING: Cables and adapters from other
suppliers could damage system components due
to different internal wiring.
