Meaning of the LED displays
LED
Behaviour
Meaning
PS
off
Electronics operating voltage (system supply) is not connected
or has fallen below the minimum supply voltage for the
electronics (CTEL master module is not active).
Lights up green
Supply voltage for the electronics is connected; supply for all
I-ports OK.
Flashes green (approx. 1 Hz) Undervoltage of the power supply.
PL
off
Several causes are possible:
–
Load supply voltage is not connected (device supply).
–
No devices at all are connected.
–
Devices are connected that do not use the PL supply
(e.g. input module CTSL-D-16E-…).
–
All 4 I-ports are configured to “Port inactive”.
Lights up green
Load supply voltage present at all connected devices and is OK.
Flashes green (approx. 1 Hz) At least one device reports undervoltage PL.
