4.1.2.3
LEDs of Input-/Output Modules
Analog 1 green: off:
analog signal not attached (only current input
modules)
on:
analog signal within range of values
flashing: analog signal outside range of values
Analog 2 green
off:
analog signal not attached (only current input
modules)
on:
analog signal within range of values
flashing: analog signal outside range of values
Power
green
on:
voltage for analog part OK
AS-i
green
on:
voltage on AS-Interface terminals OK
FAULT
red
on:
AS-Interface communication fault
flashing: peripheral fault
A peripheral fault is shown when at least one of the
signals Analog 1 or Analog 2 is outside the range of
values.
4.1.2.4
LEDs of Pt100 Module
Analog 1 green: off:
analog signal not attached
on:
analog signal within measuring range
flashing: analog signal outside measuring range
Analog 2 green
off:
analog signal not attached
on:
analog signal within measuring range
flashing: analog signal outside measuring range
Analog 3 green
off:
analog signal not attached
on:
analog signal within measuring range
flashing: analog signal outside measuring range
PWR
green
on:
voltage on AS-Interface terminals OK
FAULT
red
on:
AS-Interface communication fault
flashing: peripheral fault
A peripheral fault is shown when at least one of the
signals Analog 1, Analog 2, Analog 3 or Analog 4 is
outside the measuring range or at least one of the
analog channels is unattached.
Analog 4 green
off:
analog signal not attached
on:
analog signal within measuring range
flashing: analog signal outside measuring range
For prevention of a periphery fault by unsed channels 2, 3 and/or 4
for channel 2 between terminals 4 - 6 a 220 Ohm resistor,
for channel 3 between terminals 7 - 9 a 220 Ohm resistor,
for channel 4 between terminals 10 - 12 a bridge must be connected.
