NOTICE
The displays of the MS LED and the input LEDs I1 to I8 are identical to those for the SP-SDIO
and SP-SDI expansion modules.
Table 44: Displays of the MS LED
MS LED
Meaning
Info
Supply voltage outside of operating range
Check supply voltage at terminals A1 and A2.
/
Red/green
flashing (1 Hz)
Repairable external error
Check cable of flashing inputs and outputs.
If all output LEDs are flashing, check the
supply voltage of terminal A1 and A2 for this
module.
Green flashing
(1 Hz)
System in the stop state or the voltage supply
to A1 is outside the range of 16.8V to 30V.
Start the application in samosPLAN
6.
Check voltage supply to A1.
Green
System in the run state and the voltage supp-
ly to A1 is within the range of 16.8V to 30V.
Red flashing
(1 Hz)
Invalid configuration
Red flashing
(2 Hz)
Critical error in the system; suspected in this
module. Application has been stopped. All
outputs are switched off.
Switch supply voltage off and back on.
If the error has not been eliminated after this
has been done multiple times, then replace
module.
In order to contain the module affected, use
the diagnostics display in samosPLAN
6.
Red
Critical error in the system; suspected in a
different module. Application has been stop-
ped. All outputs are switched off.
Switch supply voltage off and back on.
If the error has not been eliminated after this
has been done multiple times, then replace
module in which the red LED is flashing
(2 Hz).
In order to contain the module affected, use
the diagnostics display in samosPLAN
6.
Table 45: Displays of input LEDs
Input LEDs (I1–I8)
Meaning
Signal level at the input terminal is 0 V.
Safety mat: Both inputs actuated.
Green
Signal level at the input terminal is 24V.
Green (1 Hz)
Synchronous with the red MS LED
Signal level at the input terminal is 0V and a
repairable error at a two-channel input is
pending.
Green (1 Hz)
Synchronously alternating with the red MS
LED
Signal level at the input is 24V and a repairab-
le error is pending.
