EZ-SCREEN
Instruction Manual
Evaluate status indicators per Section 4.4. See Section 5.2 for
Test mode indication.
A Lockout condition causes all of the EZ-SCREEN 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
Sections 5.1.1 and 5.1.2 or the Diagnostic Error Code label
supplied in the documentation pack).
The System provides easy methods for determining operating
problems. A Lockout condition is indicated by the following:
Recovery Procedures
To recover from a Lockout condition, all errors must be corrected
and a single sensor reset sequence must be performed as
described below.
Receiver Reset
Close the receiver Reset switch for 1/4 to 2 seconds and then
open the switch (per Section 4.3), or power the sensor down,
wait a second or two, then power it up.
NOTE: If the power down/up method is used and the
Emitter Reset
Power the sensor down, wait a second or two, and then power
it up.

Advanced Diagnostics
In addition to the standard error codes (see Sections 5.1.1 and
5.1.2), the EZ-SCREEN has the ability to display advanced
diagnostic codes for the purpose of factory troubleshooting and
repair functions. These codes are generally not intended for field
troubleshooting by the EZ-SCREEN user.
These advanced codes have three digits (alternating
“Axx”/“Bxx”, where “xx” are two alpha-numeric characters);
they are displayed by holding the Reset input high (+24V dc)
or holding the Invert Display button down for five seconds
during a lockout condition. If the advanced diagnostic codes are
inadvertently displayed, simply hold the Invert Display button
down for 5 seconds to return to the standard error code display.
Power failures and Lockout conditions are indication of a problem
and must be investigated immediately by a Qualified Person.
Attempts to continue to operate machinery by bypassing
the EZ-SCREEN or other safeguards is dangerous and could
result in serious bodily injury or death.
The machinery to which the EZ-SCREEN is connected must
not be operating at any time during major service or
maintenance. This may require lockout/tagout procedures (refer
to OSHA1910.147, ANSI Z244-1, or the appropriate standard for
controlling hazardous energy). Servicing the EZ-SCREEN while
the hazardous machinery is operational could result in serious
bodily injury or death.
