NORDAC START (SK 135E / SK 175E) – Users Manual for Motor Starters
74 BU 0135 en-4118
The device is equipped with two additional digital inputs for connecting initiators. However, there are
no optional outputs for connecting actuators which are operated directly via the BUS. The following
connections are each provided for four reference data bits:
BUS-IN Function (P420[-04…-07])
Status
Status
Bit 1 Bit 0
Bit 0 Enable right 0 0 Motor is switched off
Bit 1 Enable left 0 1 Field of rotation right present at motor
Bit 2 Acknowledge fault 1) 1 0 Field of rotation left present at motor
Bit 3 Release brake manually 2) 1 1 Motor is switched off
1) Acknowledge with flank 0

1.
For control via the bus, acknowledgement is not
automatically performed by a flank on one of the
enable inputs
2)
0 = Brake applied, will be released automatically if
required
1 = Brake is released immediately.
BUS-OUT Function (P434 [-01 … -02])
Status
Status
Bit 1 Bit 0
Bit 0 Fault (status bit 0) 0 0 Error active
Bit 1 Operation (status bit 1) 0 1 Standby (motor stationary)
Bit 2 1) Status of initiator 1 (DIN3 / C1) 1 0 Warning (but motor running)
Bit 3 1) Status of initiator 2 (DIN4 / C2) 1 1 Run (motor running without warning)
1) Bits 2 and 3 are directly coupled to digital inputs 3 and
4.
Parallel actuation via the BUS and the digital inputs (C1, C2) is possible. The relevant inputs are dealt
with more or less as normal digital inputs. If a changeover between manual and automatic is going to
take place, it must be ensured that no enable via the normal digital inputs takes place in automatic
mode. This could be implemented e.g. with a three-position key switch. Position 1: "Manual left"
Position 2: "Automatic" Position 3: "Manual right".
If an enable is present via one of the two "normal" digital inputs, the control bits from the bus system
are ignored. An exception is the control bit "Acknowledge fault". This function is always possible in
parallel, regardless of the control hierarchy. The bus master can therefore only take over control if no
actuation via a digital input takes place. If "Enable left" and "Enable right" are set simultaneously, the
enable is removed and the motor stops without a deceleration ramp (block voltage).
4.3.4.4 Addressing
In order to use the device in an AS-i network, it must have a unique address. The address is set to 0 in
the factory. This means that the device can be recognised as a "new device" by an AS-i master
(prerequisite for automatic address assignment by the master).
Course of action
• Ensure power supply of the AS interface via the yellow AS interface cable.
• Disconnect the AS interface master during addressing
•
Set the address ≠ 0
• Do not doubly assign addresses
In many other cases, addressing is carried out using a normal addressing device for AS interface
slaves (example follows).
• Fuchs, VBP-HH1-V3.0-V1 (separate M12 connection for external power supply)
• IFM, AC1154 (battery operated addressing device)
