Anti-Manipulation Measures
Manipulation
... during operation
(power not switched
off)
... with power off
System response System response when
power connected
Action required
Rotary switch
moved
 All outputs shut down
immediately
 System goes into
“System error”
condition
 Red FLT LED on affected
module flashes
 Green PWR LED flashes
 All other FLT LEDs
continuous red
 Message via field bus
coupler module
 System outputs cannot
be switched on

Red FLT LED on master
module flashes

All other FLT LEDs
continuous red
 Return switch to original
position (setting aid if
power remains on:
flashing PWR LED
switches to continuous
green)
 Restart system by
switching power off and
on again
Change to
control circuit
configuration
(inputs
settings on
S1 , S2 , S3 )
 Outputs of system/
system group shut
down at next cycle
 Red FLT LED on affected
module flashes
 Message via field bus
coupler module
 System/system group
outputs cannot be
switched on

Red FLT LED on master
module flashes

All other FLT LEDs
continuous red
 Restore old configura-
tions on S1, S2, S3.
 Restart system by
switching power off and
on again
Deliberate
acceptance of
an incorrect
configuration
 The configurations are
saved internally in non-
volatile form and can be
read out by the
manufacturer if required
 User reads out last
(correct) configuration
CRC via bus coupler
module
 Cyclical visual check of
configuration
The leadable cover SA-COVER is available as an accessory for the safe samos modules. It
prevents the rotary switches from changing their setting after system start-up.
Error Codes of FLT Error LED
Blink code Cause of error
 Static Secondary error on modules that have not discovered the error themselves
 2x Error in module configurations on S1, S2, S3, other module configuration
 3x Rotary switch altered during operation
 4x Module location list comparison when power switched on has detected a
difference (including alteration of rotary switch position before or during
power off)
 5x Voltage supply internal and external
 6x Self-monitoring, internal error, etc. (e.g. enter button pressed longer than 5 s)
