12.0 Using a PT Charge Controller
Pressing the SETUP button provides access to the menu items and settings that enable you to
con
fi
gure your PT charge controller. This section discusses how to set up and monitor the PT
charge controller using the ME-ARTR router. It also covers other PT controller menu options that
are available using this router. Refer to your PT controllers owner’s manual for more information
on setup and operation procedures (PN: 64-0067).
IMPORTANT:
The PT controller must be connected and communicating with the ME-ARTR in
order to set up and/or control its operation. If the PT controller is not communicating or there is
no PT connected, “
No PT Present
” appears when accessing the
METER: 07 PT Meters
,
SETUP: 07
PT Setup
or the
CTRL: 05 PT Control
menus (unless the
TECH: 08 Show all Menus
menu is set to
“
YES
”). Refer to Section 3.2.5 for more information on the
TECH: 08
menu.
12.1 Setting Up the PT Controller using the ME-ARTR
Use the ME-ARTR’s SETUP button to identify a battery type and the
Absorb Done
,
PT
Max Charge
Rate/Time, Bulk Start
,
PT Relay
VDC
,
PT Relay SOC
,
PT
Alarm
and
PT PowerSave
settings for your
PT controller. Review each menu item to determine if you need to adjust any settings to meet
your system requirements.
Info:
If
LINKED
appears on the ME-ARTR for the
07A Battery Type
and
07B Absorb
Done
displays, then that indicates that
“YES”
has been selected from the
SETUP: 01J
Link PT Charge Settings
menu. For additional information on linking the inverter’s
charge settings with the PT controller’s charge settings, refer to page 26.
• 07A
Battery Type:
This setting selects the battery type, which determines the battery
charge pro
fi
le and ensures the batteries are receiving the proper charge voltage. The charge
voltage settings are
fi
xed when using the
GEL
,
Flooded
,
AGM1
, or
AGM2
selections, but can
be adjusted if using the
CC/CV
or
Custom
selections.
Default setting:
Flooded
Range:
AGM1, AGM2, Flooded, GEL, CC/CV, Custom
◊
Battery Type (GEL, Flooded, AGM1, or AGM2)
– When the battery type selection is
GEL
(for Gel batteries),
Flooded
(for liquid lead acid batteries),
AGM1
(for Lifeline AGM batteries),
or
AGM2
(for East Penn/Deka/Discover/Trojan AGM batteries), the charge voltage level for
the Absorption, Float, and EQ charge modes are
fi
xed as shown in Table 3-1—depending on
the battery type selected and the nominal inverter battery voltage.
Info:
The voltage settings shown in Table 3-1 are based on a connected Battery
Temperature Sensor (BTS) at a temperature of 77°F/25°C, or without a connected
BMK. If the BTS is connected, the actual charge voltage will increase if the temperature
around the BTS is below 77°F/25°C, and decrease if higher than 77°F/25°C. This
ensures the batteries receive the correct charge voltage regardless of temperature.
◊
Battery Type (CC/CV)
–
The
CC/CV
selection provides a 2-stage (i.e., Constant Current/
Constant Voltage) charging method with an adjustable charge voltage and a setting that limits
output current—if needed. It consolidates all the battery charge settings that are required for
Constant Current and Constant Voltage charging cycles.
Note
:
CC/CV settings only display if
CC/CV
is selected from the
07A Battery Type
menu.
Info:
If
CC/CV
has been selected from the
07A Battery Type
menu, the
Absorb Done
and
the
Volts
and
SOC
settings (under the
07D Bulk Start
menu) are no longer accessible
and display “
CC/CV Controlled
” when selected. This is to prevent charging con
fl
icts that
could occur while in the CC/CV pro
fi
le.
CAUTION:
Whenever the CC/CV battery type is selected, some settings—within the
menus that are no longer accessible—are internally linked to the CC/CV settings and
can be automatically changed. Because settings can be automatically changed once CC/
CV has been selected, if a different battery type is selected, then all charge settings
must be reviewed to ensure they are correct for the new battery type selection.
