IC 40 function
4.9 Outputs
Various, independent signalling functions can be
assigned to the two outputs RO 1 and RO 2: closed
position, low position, middle position and high position,
fault signals and freely programmable positions.
2 relays with change-over contacts are available for
signal-ling. The contacts are floating and are thus referred
to as dry contacts. They can be integrated in automation
processes.
For instance, reaching the pre-set position can be
signalled back as a signal function. The range in which
the output switches can be defined in BCSoft
®
using the
relational operator. The range may be =, ≥ or ≤ of the set
position. Thus, for instance, the behaviour of a cam disk
can be simulated.
Example for output 1 (RO 1): if the condition is met, the
output relay is energized. Terminals 10 and 12 are
connected, see page 62 (IC 40 connection diagram).
The switching range can also be set individually via one
minimum value and one maximum value. These settings
are independent of the selected low position, middle
position or high position.
A feedback signal can also be used as a fault signal. In
BCSoft
®
, it is possible to select what status is to lead to
setting of the output (relay energized).
Device defective:
An internal fault, such as a fault in the memory chip,
leads to failure of the device.
Internal warning (reference switch):
Internal monitoring of the motor position has
detected a fault. Recalibrate!
Internal temperature > 90°C:
Warning! Attach heat deflectors.
Service note:
Number of cycles, changes of direction or relay
switching operations greater than limit.
“Fault signals” also covers a “Device in Manual mode”
signal even though the signal is not actually a fault signal.
The precise cause of the signal is displayed in BCSoft
®
and saved in the statistics, see page 61 (Statistics).
The feedback signal of the IC 40 may not be used on its
own for fail-safe signalling of a status or a fail-safe
position, see page 70 (Project planning information).
