4.2 Initial Electrical Connections
Note: The scanner's external power supply must be cable of bridging a brief power failure of 20 ms, as per
IEC 60204-1.
Note: A functional earth ground is available on pin 8 of the M12 connector. The user can connect it or
leave it floating to achieve in the application a best compliance with electromagnetic interferences.
Ensure that electrical power is not applied to the SX5 until told to do so. Do not connect any wires to the machine control
circuits (i.e. OSSD outputs) at this time.
For initial power-up and checkout, connect as described:
• Power connections (pin 2, brown wire, to +24 V dc and pin 7, blue wire, to 0 V dc)
• Reset and Zone Set inputs (pins 3, 4, and 1 (green, yellow, and white wires) depending on configuration and use)
After configuring the SX5 and performing the initial checkout procedure:
• Make the final connection of the OSSD and warning (if used) outputs
• Refer to the installation instructions of any interfacing device (i.e. UM-FA-9A/11A) for proper connection and
checkout.
If used, connect the external reset switch to the reset wire of the machine interface cordset and to 24 V dc. See warning
about the physical location of the reset switch in
on page 32. The reset switch must be a normally
open switch that is held closed for approximately 0.5 to 4 seconds, and then re-opened to accomplish the reset. The switch
must be capable of switching 10 to 30 V dc at 30 mA.
If used, connect the area switch inputs to the configured pins. This must be done to verify each Zone Set.
4.3 Electrical Connections to the Guarded Machine
CAUTION: Shock Hazard
Always disconnect power from the Banner device and the guarded machine before making any
connections or replacing any component. Use extreme caution to avoid electrical shock at all times.
Verify that power has been removed from the SX5 and the machine/vehicle to which it will connect. Make the electrical
connections described 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.
The connections for supply power, external reset (if used) and Zone Set area switch inputs (if used) should already be
connected. The SX5 must also have been configured, mounted and passed the initial checkout, as described in
on page 49.
The final connections to be made are:
• OSSD outputs
• Warning Auxiliary (if used)
• FSD/MPCE Interfacing
• Mute Sensor inputs (if used)
• Mute Enable input (if used)
• Mute Lamp output (if used)
• Override input (if used)
4.3.1 Connecting the OSSD Outputs
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.
Final switching devices (FSDs) typically accomplish this when the OSSDs go to an OFF state. Refer to the output
specifications and the warnings below before making OSSD output connections and interfacing the Scanner to the
machine.
