Lockout/Tagout

In machine maintenance and servicing situations in which the unexpected energization, start up, or release of stored energy could cause

injury, OSHA 29CFR1910.147 “The control of hazardous energy (lockout/tagout)” or ANSI 2244.1 “Lockout/Tagout of Energy Sources”

must be adhered to. The user must refer to these standards to ensure that bypassing a safeguarding device does not conflict with the

requirements that are contained within that standard.

WARNING: Limit Use of Bypass Function
The Bypass function is not intended for production purposes; it is to be used only for temporary or

intermittent actions, such as to clear the defined area of a safety light screen if material becomes

"stuck".

 When Bypass is used, it is the user's responsibility to install and use it according to relevant

standards (such as ANSI NFPA79 or IEC/EN60204-1).

Mechanical Installation

Provision to secure the enabling device is recommended and may be required as part of ensuring that the operation of the enabling

device can be supervised. The enabling device must not be affected by environmental conditions. See Specifications.

Install the enabling device so that it is protected against inadvertent operation

 (e.g., accidental actuation by being bumped or

leaned against). All mounting hardware is user-supplied.

Electrical Installation

WARNING: Shock Hazard and Hazardous Energy
Always disconnect power from the safety system (e.g., device, module, interfacing, etc.) and the

machine being controlled before making any connections or replacing any component.

Electrical installation and wiring must be made by Qualified Personnel and must comply with the relevant

electrical standards and wiring codes, such as the NEC (National Electrical Code), ANSI NFPA79, or IEC

60204-1, and all applicable local standards and codes.

Lockout/tagout procedures may be required. 

Refer to OSHA 29CFR1910.147, ANSI Z244-1, or the ap-

propriate standard for controlling hazardous energy.

It is not possible to give exact wiring instructions for a device that interfaces to a multitude of machine control configurations. The follow-

ing guidelines are general in nature.
Use a risk assessment to determine the method of interfacing this device. At a minimum, use the same level of safety performance (e.g.,

control reliability, category 3 or 4) for the safeguard being bypassed.

Do not simply connect the contacts of the enabling switch across the contacts of a bypassed safeguarding device

 (e.g., inter-

locked guard/gate, safety light screen) in a parallel connection. The enabling device(s) could be rendered ineffective by simply re-estab-

lishing the safeguarding device (closing the interlocked guard/gate, clearing the safety light screen).

At a minimum, the machine control must:

• Provide a means for supervisiong the selection of the enablin device in order to prevent unauthorized use or de-selection (disabling)

while in use. Methods include key-operated controls, controls located under lockable covers, controls that require a password, or

securing th enabling device(s) within lockable storage.

• Reduce risk to the individual using the enabling device by reducing machine performance (such as reducing speed, reducing power

or force, or allowing only an incremental step-by-step operation, e.g., “inch/jog”).

• Provide visual means to indicate that the enabling device/function is active or has been selected.
