Operation
• PT Tech Menus
a.
PT Temperatures:
• PT BTS - Shows the temperature of the BTS which is used for battery charging temperature
compensation (refer to Section 4.7).
Note:
If there is more than one BTS connected, then in
order of priority, the BTS on the inverter is used
fi
rst; then the BTS with the lowest address
(i.e., master controller); then the controller with the next lowest address (i.e., slave controller).
• PT FETs - Highest FET temperature from any of the stacked controllers.
• PT Inductor - Highest inductor temperature from any of the stacked controllers.
b. PT Version - Shows the PT software version if every stacked controller has the same version.
Note:
It should show version 1.0 or higher; however, if display shows 0.9, then there are multiple
software versions between the stacked controllers. In this case, you can perform a Power-up Test
(see Section 2.12.2) to view each controllers display to determine the software version.
c. PT Faults - Indicates any fault that occurs on any stacked controller. View the front panel display
of each controller to determine which controller has the fault. Refer to Section 5-3 to resolve the
indicated fault.
Note:
Any controller with a fault that can be reset, must be cleared using the RESET button on
that controller.
Note:
Only one fault is displayed on the remote; however, there may be multiple faults. Check the
front panel display on every stacked controller for any fault indication.
Info:
The HiBatt Temp -PT (F07) and Ground Fault -PT (F12) faults are transmitted to
all the stacked controllers. If either of these two faults is shown, the fault has probably
occurred on only one controller, most likely the controller designated as the master.
4.13.4 Network Control from Remote to Stacked Controllers
When multiple controllers are enabled to stack and network, the PT control menus in the ME-ARC
remote (version 4.0 or higher) and the ME-ARTR (Advanced Router) can be used to control the
multi-controller system. On the following PT control menus, any setting selected is transmitted to
all the controllers that are networked (or stacked) together to follow.
PT Control Menus
• PT Charge Control - Settings: Multi-Stage, Charger Off, Start Float, Start Bulk, Start EQ (5sec)*
*The front panel of the master controller can also be used to start/stop EQ charging on all stacked
controllers.
Note:
The ability to start/stop EQ charge is disabled on all slave controllers.
• PT Aux Relay - Settings: Disengage, VDC, Fault, Engage
• PT Alarm - Settings: Off, VDC, Fault, On
• PT MPPT Control - Settings: 5 Min Sweep, 15 Min Sweep, 1 Hour Sweep, Fixed Sweep
Note:
To ensure the controllers that are networked/stacked together are truly communicating with
each other, use the remote to issue a CTRL start command and see if the command is performed by
all the PT-100’s. This is done by pressing the CTRL button on the remote and rotating the SELECT
knob to the PT Control menu. Then press the SELECT knob to enter a CTRL ‘Start’ command such
as: Start Float or Start Bulk.
4.13.5 Battery Temperature Sensor Operation when Stacked
When connecting PT controllers together in a stacked system con
fi
guration, ensure the BTS is
connected to the inverter, as it will provide its BTS information to the inverter and also to the
networked controllers (only BTS on inverter is required, no other BTS is required).
Note:
If a BTS is only connected to a networked controller, the BTS information on the controller
will not be used by the inverter.
