4 Electrical Connections
WARNING:
•
Make the proper electrical connections
•
Connecting equipment to the SX other than what is described in this manual could result in serious
bodily injury or death.
•
Make no more connections to the SX than are described in this manual.
•
Electrical connections must be made by Qualified Personnel and must comply with NEC (National
Electrical Code) and local standards.
Lockout/tagout procedures may be required (refer to OSHA 29CFR1910.147, ANSI Z244-1, or the appropriate standard for
controlling hazardous energy). Following relevant electrical standards and wiring codes, such as the NEC, NFPA79 or
IEC60204-1, always connect ground (red wire, see wiring diagrams).
4.1 Routing Cordsets
Connect the SX to the machine interface through the appropriate M12/Euro-style machine interface connector(s) using color-
coded cable wiring according to safety equipment regulations. Banner provides accessory cables with color-coded wiring
(referenced in this manual) in compliance with the regulations and standards.
Attach the required cordsets to the SX and route the Machine Interface cable to the junction box, electrical panel, or other
enclosure in which the safety module or other safety related parts of the control system are located. This must be done per
local wiring code for low-voltage dc control cables and may require installation of electrical conduit. For information on
Banner's accessory cables, see
on p. 114.
Attach the 4-pin M12 ethernet cable if it is to be permanently installed. If the connection is only to be used during
configuration (and troubleshooting), route the cable to the PC such that it does not interrupt the scanning field. After the
configuration is complete, remove the PC interface cable and replace the dust cover.
The SX is designed and manufactured to be highly resistant to electrical noise and to operate reliably in industrial settings.
However, extreme electrical noise may cause a random Trip or Latch condition. In extreme cases, a Lockout is possible. SX
wiring is low voltage; routing the cables alongside power wires, motor/servo wires, or other high voltage wiring may inject
noise into the SX.
It is good wiring practice (and may be required by code) to isolate the SX cables from high-voltage wires, avoid routing
cables close to noisy wiring.
Important:
The standard SXA cables are unshielded cables. If shielded cables are used, provide a good
earth ground connection to the cordset shield.
4.2 Initial Electrical Connections
Note:
The scanner's external power supply must be capable of bridging a brief power failure of 20 ms, as
per IEC 60204-1.
Note:
A functional earth ground is available. See
Machine Interface Connections for the Stand-alone
on p. 51,
Machine Interface Connections for the Master Models (8-pin)
on p. 55,
Interface Connections for the Master (12-pin)
Machine Interface Connections for the Master
on p. 60.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 SX 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 (to find the pin numbers and wire colors, refer to the appropriate
machine interface wiring section for the model of scanner being used):
•
Power connections
•
Reset and Zone Set inputs
•
If EDM has been configured, it must be wired. Wire the OSSDs to the relays/contactors but do not wire the relay
outputs to the machine. Wire the NC contacts to the EDM pin selected in the configuration.
After configuring the SX 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.
