BasicController CR0403
Output group OUT4...OUT7
These outputs are a group of multifunction channels.
These outputs provide several function options (each output separately configurable):
• binary output, plus switching (BH)
• analogue output with Pulse Width Modulation (PWM)
• These outputs are not able for diagnosis.
→ chapter Possible operating modes inputs/outputs
► Configuration of each output is made via the application program:
→ FB OUTPUT
PWM output: → FB PWM1000

Diagnosis: binary outputs (via voltage measurement)
The diagnostics of these outputs is made via internal voltage measurement in the output:

Diagnosis: overload

The outputs have no current measuring, no overload detection.

Diagnosis: wire break (via voltage measurement)
28853
Wire-break detection is done via the read back channel inside the output.
Prerequisite for diagnosis: output = FALSE
Diagnosis = wire break: the resistor Ru pulls the read back channel to HIGH potential (power supply)
Without the wire break the low-resistance load (RL < 10 kΩ) would force a
LOW (logical 0).
Diagnosis: short circuit (via voltage measurement)
Wire-break detection is done via the read back channel inside the output.
Prerequisite for diagnosis: output = TRUE
Diagnosis = short circuit against GND: the read back channel is pulled to LOW potential (GND)

3.2.4 Note on wiring
28579
The wiring diagrams ( → installation instructions of the devices, chapter "Wiring") describe the standard device configurations. The wiring diagram helps allocate the input and output channels to the IEC addresses and the device terminals.
The individual abbreviations have the following meaning:
A Analogue input
BH
BL
CYL
ENC
FRQ
H bridge
PWM
PWMi
IH
IL
Binary high side input: minus switching for negative sensor signal
Binary high side output: plus switching for positive output signal
Binary low side input: plus switching for positive sensor signal
Binary low side output: minus switching for negative output signal
Input period measurement
Input encoder signals
Frequency input
Output with H-bridge function
P ulsew idth m odulated signal
PWM output with current measurement
Pulse/counter input, high side: minus switching for negative sensor signal
Pulse/counter input, low side: plus switching for positive sensor signal
R Read back channel for one output

3.2.5 Safety instructions about Reed relays
28354
For use of non-electronic switches please note the following:
Contacts of Reed relays may be clogged (reversibly) if connected to the device inputs without series resistor.
► Remedy: Install a series resistor for the Reed relay:
Series resistor = max. input voltage / permissible current in the Reed relay
Example: 32 V / 500 mA = 64 Ohm
► The series resistor must not exceed 5 % of the input resistance RE of the device input → data sheet). Otherwise, the signal will not be detected as TRUE.
Example:
RE = 3 000 Ohm
max. series resistor = 150 Ohm
