Internal settings
The SM1690x comes in the default settings with all
the SW1 switches= OFF and switch 3 of SW2= OFF:
nevertheless some working parameters can be modifyed
using internal dip-switches.
DIP-SWITCH #1 (on board M416.x: see position on next
page): allows to override some external alarms, as follow
SW1-1 if set to ON disables ARC DETECTOR alarm.
SW1-2 if set to ON disables MAGNETRON THERMAL
alarm
SW1-3 if set to ON disables AIR FLOW alarm
SW1-4 if set to ON disables WATER FLOW alarm
SW1-5 if set to ON disables HEAD ENABLE
SW1-6 if set to ON disables microswitch CARTER alarm
SW1-7 if set to ON inhibits the automatic opening of the
interlock relay from the CPU in case of alarm. If it is ON,
only the opening of the MICRO CARTER switch can de-
energize
the interlock relay, cutting in this way the head supply and
leaving the head in a safe condition.
SW1-8 – not used.
DIP-SWITCH #2 (on board M416.x)
SW2-1: not used
SW2-2: not used
SW2-3 if set to OFF enables the external control of the
unit, set to ON enables the fieldbus control.
The default setting for SM1690x is OFF.
WARNING: in ON state, if no fieldbus interface is
present or if no communication is present on the bus,
an alarm is generated.
SW2-4
must be set to OFF for normal
operation
, if set to ON enables the
hardware test of the M416 board.
WARNING:
don’t enable
this switch: the
use is limited to
trained personal
only and for test
purposes.
