LEDs
The FPTC-02 module has three diagnostic LEDs.
DescriptionColorName
The motor temperature is outside the permitted
temperature range and the drive STO is active, or
there is no PTC sensor connected to the XFLT input
(safety-related).
RedFAULT
The motor temperature is outside the temperature
warning range, or there is no PTC sensor connected
to the XWRN input (non-safety-related).
RedWARNING
The module is powered up.GreenSTATUS
Note: When there is no sensor connected to the XWRN input, the
WARNING LED is red even if you have suppressed the warnings
from the module. You can connect a resistor (100 ohm … 1 kohm
1/4 W wire-wound) in the XWRN input to turn off the WARNING LED.
