Interfaces and Operation
Clamps
I1, I2, I3, I4 Inputs for connection of signal transmitters /
sensors (functional group A)
X1, X2, X3, X4 Outputs only for input circuit voltage or
rather control sensors of the module
(functional group A)
I5, I6, I7, I8 Inputs for connection of signal transmitters /
sensors (functional group B)
X5, X6, X7, X8 Outputs just for the input circuit voltage or
rather control sensors of the module
(functional group B)
SBus 10-pin connector for safety bus (plug and
nut)
Push-buttons
INPUT A
INPUT B
10-staged torque switch for adjustment of an
input circuit function (functional group A or
rather B)
LEDs
I1.. I8 (green)
PWR (green)
QA (green)
QB (green)
FLT (red)
Indicators of according inputs
Voltage supply
Overall indicator of inputs I1..I4 (functional
group A)
Overall indicator of inputs I5..I8 (functional
group )
Indicator of flawed operating modes
(see FLT error codes page 63)
