not the case. Inter-tier straps, charger cables or string voltage/ripple channels can be specified on the
Batteries page using the cells only configuration.
Which temperature probe (TP) ports are being used?
There are four hardware connections on the Frontier unit for temperature probes. These are probes
that can be placed throughout the string or used for ambient temperature readings. Check the number
of temperature probes to be used and ensure that the hardware is plugged into the corresponding TP#
port on the Frontier unit. Any combination of TP ports can be used.
Which current transducer (CT) ports are being used?
There are 2 (or 4, depending on the Frontier model) hardware connections on the Frontier unit for
current probes. Current probes can be placed on the charger cable or a bus cable in the string to
measure the current flow. Different models of current probes may be used to monitor float, discharge,
and charge currents. Check the number and type of current probes to be used and ensure that the
hardware is plugged into the corresponding CT# port on the Frontier unit.
Digital input bits (DIB)
Frontier has 4 digital input bits (DIB) available in order to incorporate third party devices into the
system. Examples of devices that can be integrated into Frontier include ground fault detectors,
hydrogen sensors, or electrolyte leak detection systems. Once battery design is completed, any DIBs
being used can be configured by navigating to DIB Alarms under the Settings menu.
Individual cell temperatures
Frontier will automatically detect a system with temperature sensing DCM units and will display
individual cell temperature readings on the Home page along with voltage and ohmic value
measurements. No further configuration is required for this feature.
When completed, press the Next button at the top of the page to continue to the next step.
Batteries
Frontier uses terminology in line with industry standards to describe the parts of the battery system.
Terminology
 Battery – A battery is the entire unit connected to the DC charger
 String – A number of containers connected in series which can be a parallel feature of the
battery
 Jar, container, or cell – The lowest changeable unit of a string
How many batteries?
Up to four batteries can be monitored by a single Frontier unit. This is due to the limited number of CT
ports available in Frontier. Each battery must have at least one CT assigned to it. Edit this field with the
number of batteries in the system and the page will update with available settings for each. Batteries
hold their properties along with the corresponding string properties nested underneath them in the user
interface.
