8 Pre-reset function
NB! The Pre-reset function is an addition to the manual reset function. It can be used, where the operator
doing the reset is not able to see the entire hazardous zone.
The pre-reset pushbutton must be installed in the (hazardous) zone from where the operator is able to
check that nobody else is in the hazardous zone before the manual reset function is used. Failure to do so
may result in serious injury.
• Pre-reset function sets the Focus II system to manual reset mode.
• Blanking function can not be selected using pre-reset function.
• Muting function can not be selected using pre-reset function.
• The time limit between pre-reset and manual reset is 8 s.
Pre-reset setup and connection example
• Enable pre-reset mode with the internal change-over switches (See 4.4).
• Connect a pre-reset button  to MUTING A input (green) and +24 VDC to MUTING B input (yellow).
