Banner EZ-SCREEN­ Safety Light Curtain Systems - Manual (Page 34)

Electrical Connections to the Guarded Machine
Make the electrical connections as described in the following sections ( OSSD Output Connections on page 34 to FSD Interfacing
Connections on page 35 as required by each individual application.
Lockout/tagout procedures may be required (refer to OSHA 1910.147, ANSI Z244-1, or the appropriate standard for controlling hazard-
ous energy). Follow relevant electrical standards and wiring codes, such as the NEC, NFPA79 or IEC 60204-1.
Supply power and the external reset switch should already be connected. The EZ-SCREEN Type 2 must also have been aligned and
passed the Initial Checkout, as described in
Initial Checkout Procedure on page 28.
The final connections to be made are:
• OSSD outputs
• FSD interfacing
• MPCE connections
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.
Final Switching Devices (FSDs) typically accomplish this when the OSSDs go to an OFF state.
Refer to the output specifications in Specifications and Accessories on page 52 and the warning below before making OSSD output
connections and interfacing the EZ-SCREEN Type 2 to the machine.
CAUTION: Shock Hazard
Always disconnect power from the EZ-SCREEN Type 2 and the guarded machine before making any con-
nections or replacing any component. Use extreme caution to avoid electrical shock at all times.
