5. Repeat steps 1 through 4 for each of the Field Pairs that have been configured if Field Pair Switchover is used.
Ensure that all fields correspond to the expected fields as determined by the risk assessment. If not, do not
continue until the situation is corrected.
6. After all corrections and changes to the configuration and the Warning and Protective Fields have been verified,
proceed to Section 3.7.
3.7 Electrical Interface to the Guarded Machine
3.7.1 Permanent Hookup
Verify that power has been removed from the Scanner and the machine/vehicle to which it will connect. Make the
electrical connections as described in Sections 3.7.1 to 3.7.5 as required by each individual application.
Lockout/tagout procedures may be required (refer to OSHA CFR 1910.147, ANSI Z244-1, or the appropriate standard
for controlling hazardous energy). Follow relevant electrical standards and wiring codes, such as the NEC, NFPA79 or
IEC 60204-1. See the warning in Section 3.5.
The connections for supply power and the external reset switch should already be connected. The Scanner must also
have been configured, mounted and passed the initial checkout, as described in Section 3.6.
The final connections to be made are:
OSSD outputs
FSD interfacing
MPCE/EDM connections
Alarm (Auxiliary) Outputs
3.7.2 OSSD Output Connections
Both the output signal switching device (OSSD) outputs must be connected to the machine control so that the machine’s
safety-related control system interrupts the circuit or power to the machine primary control element(s) (MPCE), resulting
in a non-hazardous condition.
WARNING . . . IF TRIP TEST INDICATES A PROBLEM
If the Scanner does not respond properly to the trip test, do not attempt to use the system. If this occurs, the Scanner cannot be relied on to
stop dangerous machine motion when a person or object enters the Protective Field. Serious bodily injury or death could result.
WARNING . . . SHOCK HAZARD
Always disconnect all power from the Scanner and the guarded machine before making any connections or replacing any component.
Use extreme caution to avoid electrical shock at all times.
