12.1.3 Special alarms, warnings and signals
M S
The master indicates that not all slaves are
online.
S- ?
Common alarm from a slave
This alarm is generated if a slave can’t be contacted anymo-
re while the master has set the power output to ON. It can
occur if the System Link is broken or if the slave has been
switched off by the mains switch.
S-PH
An alarm or
S-PH
a warning with „Auto ON“ setting
is indicated if the connection to a slave is lost in case that
the slave has been switched off or a mains voltage loss has
occured. PH = phase blackout
A warning with „Auto ON“ setting switches the power output
off until the cause of the failure/error is removed or has
gone. The system will then automatically switch the output
on again. The error has to be acknowledged and will turn
into a signal if it still persists. The signal vanishes if the error
is removed or gone.
If there will be an alarm or warning with „Auto ON“ depends
on the setting „Reactivation after power ON“ (see user
manual of series PSI 9000, section „Defining operation
parameters“).
Power ON Default: OFF
= OFF Power output is off (standby) after return of
the mains voltage or after the unit has been
switched ON.
= restore Power output is automatically set to the last
state it had before the unit was switched off
or before a mains voltage loss occured. This
can be ON or OFF.
S-OT
An alarm or
S-OT
warning with „Auto ON“ setting
is indicated, if one or multiple slaves experienced and repor-
ted an overtemperature in the power stages.
If there will be an alarm or warning with „Auto ON“ depends
on the setti ng „Reactivation after power ON“ (see user
manual of series PSI 9000, section „Defining operation
parameters“).
OT disappear Default: auto ON
= OFF The power output will stay switched OFF after
the overtemperature has disappeared and the
power stage is cooled down.
= Auto ON The power output is automatically switched
ON again after the overtemperature has dis-
appeared and the power stage is cooled down.
S-OV
One or multiple slaves have reported an overvoltage pro-
tection error. The power output will be switched OFF and
can only be switched ON again after the alarm has been
acknowledged.
12.2 Configuration of the System Link Mode
In order to use the System Link Mode it first has to be set
up and configured. The extra ports (SIO2) on the cards IF-
R1 or IF-U1 have to be linked to a corresponding port of the
next unit. A CAT5 patch cable is included in the package.
The end units will be bus terminated by a setting in the pa-
rameter setup page.
Enter the menu of any device, activate the communication
menu and select the card to configure:
Slot {A|B}: IF-R1 {IF-U1} +
SIO2 Default: not used
= not available The SIO2 ports are not available.
= not used The SIO2 ports are not used.
= {Master|Slave}
The unit is dened as master or slave
The following two parameters only appear if the device is
dened as Master:
Matrix of modules
Here you „tell“ the master how many units are connected
in parallel or series.
serial Default: 1
= {1..x} Set the number of units connected in series.
A 2 means, that two units are connected etc.
The allowed number of serially connected units also
depends on the maximum acceptable isolation voltage!
parallel Default: 1
= {1..30} Dene the number of units which are con-
nected in parallel, no matter if directly to the
master or not. A 2 means, that two units are
connected in parallel etc.
The following two parameters only appear, if the device is
defined as Slave:
Position of module
The parameters here define the position of a slave unit
within the system. Every position within a system of
serially or parallel connected devices must be unique!
serial Default: 1
= {1..x} Set the position of the device in the system
(see gure below).
The allowed number of serially connected units
also depends on the maximum acceptable isolation
voltage!
