System Operation
Security Protocol
Certain procedures for installing, maintaining and operating the EZ-SCREEN Type 2 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 Type 2. The Designated Person is empowered to:
• Perform manual resets and hold possession of the reset key (see
on page 43), and
• 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 Type 2 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 Type 2 System
• Perform all checkout procedures
• Make changes to the internal configuration settings
• Reset the System following a Lockout condition
Reset Procedures
Resetting the System
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
on page 18). 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 will also provide some level of personal control, since the key may be removed from the switch. This
will hinder 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.
Receiver Resets
The EZ-SCREEN Type 2 receiver has a Reset input, pin 8 (Violet wire), that allows the System to be manually reset.
Receiver manual resets are required in the following situations:
• Trip Output operation – only after a System Lockout (see Section 5 for causes).
• Latch Output operation – at power-up, after each Latch condition occurs, and after a System Lockout.
Reset Procedure
To reset the receiver, open the reset switch for 1/4 second, then close it.
