6.1.3 Special alarms, warnings and signals
M
S
The master indicates that not all slaves are
online.
S- ?
Alarm from a slave
An alarm is generated if a slave can't be contacted anymore
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.
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
= 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 notified
an overtemperature in the power stages.
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").
OT disappear
= 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 disap-
peared and the power stage is cooled down.

OFF
Default:
auto ON
S-OV
One or multiple slaves have notified an overvoltage pro-
tection error. The power output will be switched OFF and
can only be switched ON again after the alarm has been
acknow-ledged.
6.2 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 (SIO) 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 terminated by a setting in the parameter
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
= not available
The SIO ports are not available.
= not used
The SIO ports are not used.
= {Master|Slave}
The unit is defined as master or slave
The following two parameters only appear if the device is
defined as Master:
Matrix of modules
Here you „tell" the master how many units are connected
in parallel or series.
serial
= {1..x}
Set the number of units connected in series
to the master, no matter if directly or not (see
figure below).
The allowed number of serially connected units also de-
pends on the maximum acceptable isolation voltage!
parallel
= {1..30}
Set the number of units which are connected
in parallel, not matter if directly to the master
or not.
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 seri-
ally or parallel connected devices must be unique!
serial
= {1..x}
Set the position of the device in the system
(see figure below).
The allowed number of serially connected units
also depends on the maximum acceptable isolation
voltage!
