6 Operating Instructions
6.1 Security Protocol
Certain procedures for installing, maintaining, and operating the EZ-SCREEN must be performed by either Designated
Persons or Qualified Persons.
A Designated Person is identified and designated in writing, by the employer, as being appropriately trained and qualified to
perform system resets and the specified checkout procedures on the EZ-SCREEN. The Designated Person is empowered
to:
• Perform manual resets and hold possession of the reset key
• Perform the Daily Checkout Procedure
A Qualified Person, by possession of a recognized degree or certificate of professional training, or by extensive knowledge,
training, and experience, has successfully demonstrated the ability to solve problems relating to the installation of the EZ-
SCREEN System and its integration with the guarded machine. In addition to everything for which the Designated Person is
empowered, the Qualified Person is empowered to:
• Install the EZ-SCREEN System
• Perform all checkout procedures
• Make changes to the internal configuration settings
• Reset the System following a Lockout condition
6.2 System Configuration Settings
Set the System settings using the configuration panels located on each sensor, behind the access cover. The access cover
is opened by first removing the factory-installed security plate with the security hex wrench provided. Re-install the security
plate after any configuration changes.
Figure 24. EZ-SCREEN Configuration DIP Switches (Receiver)
SC1 or SC2—Scan Code 1 (default) or Scan Code 2
T or L (Bank A)—Trip (T) (default) or Latch (L) Output
RR or Off—Reduced Resolution (default: Off)
T or L (Bank B)—Trip (T) (default) or Latch (L) Output ; the
switch settings for bank A and bank B must match
RR or Off (Bank B)—Reduced Resolution (default: Off); the
switch settings for bank A and bank B must match
E1 or E2—EDM 1-Channel or EDM 2-Channel (default); if
the EDM wiring does not match the switch position shown
(E2), an EDM error occurs and fixed blanking or cascade
configuration will not be allowed.
Because it has redundant microprocessors, the receiver has two DIP switch banks (bank A and bank B) that must be set
identically. Failure to do so will cause a Lockout condition when power is applied. Power to the EZ-SCREEN receiver should
be OFF when changing DIP switch settings or a Lockout will occur.
After configuration settings are verified/set, fully close (snap shut) the access cover to maintain IP ratings. Other than the
Scan Code, all configuration settings should be changed only when the System is off.
Note: The corresponding pairs of DIP switches must be set identically for the System to operate.
Scan Code allows the operation of multiple pairs of emitters and receivers in close proximity. Set the Scan Code to 1 or 2
using the switch on the configuration panel. The Scan Code setting for each emitter must match with its corresponding
receiver. The Scan Code settings may be changed while in Run mode without causing a Lockout.
