12.1 Lockout Conditions
WARNING:
• Shut down the machinery before servicing
• Servicing the Banner device or system while the hazardous machinery is operational could result
in serious injury or death.
• The machinery to which the Banner device or system is connected must not be operating at any
time during major service or maintenance. This might require lockout/tagout procedures (refer to
OSHA1910.147, ANSI Z244-1, ISO 14118 or the applicable standard for controlling hazardous
energy).
A Lockout condition causes all of the EZ-SCREEN LPM OSSD outputs to turn or remain Off, sending a stop signal to the
guarded machine. Each sensor provides diagnostic error codes to assist in the identification of the cause(s) of lockouts (see
(p. 78)) or the Diagnostic Error Code label supplied in the
documentation pack).
WARNING:
• Lockouts and power failures indicate a problem
• Attempts to continue to operate machinery by bypassing the Banner device or other safeguards
is dangerous and could result in serious injury or death.
• A Qualified Person

must immediately investigate the problem.

12.2 Reset Procedures
System resets are performed using an external reset switch. This switch must be located outside the guarded area, and
must not be within reach from within the guarded area (see
(p. 23)). Its location should provide a
clear view of the entire safeguarded area. If any hazardous areas are not in view from the switch location, additional means
of safeguarding must be provided. The switch should be protected from accidental or unintended actuation (for example,
through the use of rings or guards).
If supervisory control of the reset switch is required, a key switch may be used, with the key kept in the possession of a
Designated or Qualified Person. Using a key switch provides some level of personal control, since the key may be removed
from the switch. This hinders a reset while the key is under the control of an individual, but must not be relied upon solely to
guard against accidental or unauthorized reset. Spare keys in the possession of others or additional personnel entering the
safeguarded area unnoticed may create a hazardous situation.
