10.2.2 Troubleshooting 2
●
l An error code displays on the remote controller.
●
l The LED on the Lossnay circuit board is blinking or lit up.
An error code displayed on the remote controller (PZ-60DR-E, PZ-41SLB-E, PZ-52SF-E) or the M-NET con-
troller, and blinking or illumination of LED1 (green) or LED2 (red) on the circuit board shows the type of error.
The LED blink interval is 0.25 seconds for both on and off. The display duration is approximately 5 seconds.
Checklist of error codes displayed on the PZ-60DR-E (when not using M-NET) or PZ-41SLB-E, and LED displays (Table2-1)

Cause Action
« Turn off the main power supply and set the
Main/Sub selection switch (SW1) (first unit to
"Main", second and following units to "Sub").
« Using suitable cables, wire the
transmission cables so that they are
separated from one another.
« Wire the transmission cable at least 5
cm away from the power supply cable.
« Check the transmission cable connection.
« Check the length of the transmission
cable wiring.

« Replace the remote controller.
« Check the trial operation switch.
