When there is a collective diagnostic (input byte 0, bit 4 (DIAG)), the
DS7-SWD soft starter will provide advanced diagnostic messages:
Motor-protective circuit-breaker diagnostic messages (profiles 1 to 9)
The following are the messages generated by the PKE motor-protective
circuit-breaker:

3 No communication
Between DS7-SWD soft
starter and PKE trip block
Soft starter diagnostic messages (profiles 1 to 11)
The following are the messages generated by the DS7-SWD soft starter:
Table 43: DS7-SWD soft starter diagnostic messages
Value Meaning
[hex]
14 Internal communication
problem in soft starter
15 no unambiguous position
of the 1-0-A switch for
more than 4 seconds
19 There is a DS7-SWD
soft starter warning.
1A There is a DS7-SWD
soft starter fault.
Diagnostic alarm 15
If the 1-0-A switch does not assume a clear position for longer than
4 seconds, the DS7-SWD soft starter will be switched off and generate
the following error messages:
• DIAG,
• ERR (only profiles 4 to 11),
• Diagnostic alarm 15
In addition, the module's SmartWire-DT diagnostic LED will flash green
(frequency: 3 Hz).

Remedy
Check whether the PKE trip block
being used is a PKEXTUA-... trip
block.
Check the PKE32-COM
connections and reconnect the
device if necessary.
Remedy
• If the error continues, switch
the supply voltage off/on
• Check EMC
• Replace soft starter
Move the 1-0-A switch to one of
the three defined positions.
Read warning PNU 860.0 and fix
the cause
• Read fault PNU 944 to
PNU 952
• Fix the fault and
acknowledge the error

Notes
The DS7-SWD can continue to be
used in this state. The main circuits
are isolated by the PKE in the event
of an overload.
In these cases, an enabled overload
function (ZMR) will not have any
effect.
Notes
–
Value 00 is signaled using input
hex
byte 0, bits 2 and 3.
