1.7 Description of system components
1.7.1 Basic units (BU)
The basic units are the fundamental components of the SIMOCODE pro
system. Basic units are always necessary when using SIMOCODE pro.
They have a standard enclosure width of 45 mm and are equipped with
detachable terminals:
Fig. 1-6: Basic units
Basic units can be installed on a standard mounting rail or fixed to a
mounting plate (with additional push-in lugs).
Basic units are available in two versions for the following supply voltages:
•24V DC or
• 110 to 240 V AC/DC.
Basic unit 1 (BU1)
Basic unit 1 is the fundamental component of the SIMOCODE pro C device
series and is used in combination with a current measuring module and
optional operator panels. The following motor control functions are
supported:
• Overload relay
• Direct starters and reversing starters
• Circuit breaker control (MCCB).
LEDs for device diagnostics (Device, Bus, Gen.Fault):
These LEDs on the front of the device are used for device and fault
diagnostics, and indicate the basic status
• Of the device itself via the Device LED
• About PROFIBUS communication via the Bus LED
• About any motor feeder faults via the Gen. Fault LED
For more information see Chapter 14.2.3.
