Stack ComLost-PT
– The controller was previously communicating on the network, but
now it is no longer receiving any communications from the Magnum inverter or from another
controller.
Note:
The controller continues to run with this fault.
Remedy:
This fault can be caused by:
1. A stack or network cable was damaged or disconnected.
a) Examine the cables for any damage and replace if needed, or try another remote
and/or stack cable.
2. The network or stack cable has been disconnected or the connection is now bad.
a) Inspect both ends of each network or stack cable to ensure they are clean and
not damaged; also, inspect the inverter’s and controller’s NETWORK ports and the
controller’s stack ports to ensure there is no debris or damage.
3. The inverter is no longer powered or it’s communication port is faulty.
a) Ensure the inverter has power and is able to turn on and off.
b) If the router is powered and communicating, then the remote port is working; in
this case, remove the network cable from the NETWORK port and connect it to the
inverter’s REMOTE port to see if it now starts communicating.
The fault will automatically clear and the controller will resume operation once it receives
communications from the network (or from another controller).
This fault can also be manually cleared by pressing the RESET button on the front of the
PT controller for a minimum of two seconds.
Info:
Even though network communications has stopped, all network settings
in the controller remain until disconnected from both PV and battery power.

Stack Switch Fault
– The PT controller is not able to run because the controller’s stacking
address has been incorrectly set.
Remedy:
1. Ensure the stacking address is not set to “
C00
”.
a) C00 is an invalid stacking address, examine DIP switches 7, 8, and 9 to ensure
that only C01-C07 is set as the stacking address.
2. Ensure none of the stacked controllers have the same stack address.
a) Each controller must have its own unique stack address. Examine DIP switches 7,
8, and 9 to ensure each controller address is different—and not set to C00.
3. If stacking
cables have been connected between controllers, ensure stack mode
(DIP switch 10 set UP) has been enabled.
a) Set DIP switch 10 to the UP position (stack enabled) on every controller connected
together in a stacked con
fi
guration.
The fault will automatically clear and the controller will resume operation once the
correct stack address is set.
•
USB Fault
– This fault indicates that the USB port on the PT is plugged into a computer as the
unit is attempting to convert power.
Note:
This fault typically occurs when a software update
is performed and the USB cable hasn’t been unplugged.
Remedy:
Ensure nothing is connected to the USB port on the PT-100, then press and
hold the RESET pushbutton for one second. This should clear the fault and turn the
controller on.
•
Unknown Fault ##
– The PT controller has sent a fault code that cannot be determined by
the router.
Remedy:
Contact Sensata Technical Support (425) 353-8833 for assistance in identifying
the actual fault condition.
