EZ-SCREEN
®
AC Interface Box
Initial Checkout
NOTE: The EZ-SCREEN AC Interface box can be used safely only when its operation is
controlled via an appropriate primary safeguarding device (such as the Banner EZ-
SCREEN light screen) and connected to the interface according to the wiring diagrams
shown in Figures 5-12.
Procedure:
1. Remove the power that controls (and is switched by) the machine primary control elements
(see Warning at right).
2. Verify that the AC Interface Box indicator LED is ON either Green or Red. Verify that the
primary safety device controlled by the box is operating correctly, according to its product
documentation and manufacturer’s recommendations.
3. Confirm proper connection of the box to the controlled primary safety device according to
the appropriate wiring diagram (see Figures 5-9).
4. Verify that all box output contacts follow exactly the operation of the safety output contacts
of the controlled Primary Safety Device, when the primary safety device is operated
according to its product documentation and manufacturer’s recommendations.
Refer to EZ-SCREEN or primary safeguarding device literature for full checkout procedures.
Periodic Checkout Procedure
The initial checkout procedure described above should be performed according to the intervals
specified by the product documentation of the primary safety device controlling the interface
module integrated within the EZAC box.
Repairs
Do not attempt any repairs to the box, other than replacing the relay module with an original
Banner replacement relay module (see information below). Other than the relay module,
the box contains no field-replaceable components; for other problems, return the box to the
factory for warranty repair or replacement.
If it ever becomes necessary to return a box to the factory, please do the following:
1. Contact the Banner Factory Application Engineering Group at the address or at the
numbers listed at the bottom of the back page. They will attempt to troubleshoot the
system from your description of the problem. If they conclude that a component is
defective, they will issue an RMA (Return Merchandise Authorization) number for your
paperwork and give you the proper shipping address.
2. Pack the box carefully. Damage that occurs in return shipping is not covered by warranty.
Relay Module Replacement
Replacement relay modules are dependent on the box model. To order the correct
replacement module, refer to the table at left.
CAUTION ...
Disconnect
Power Prior to Checkout
Before performing the initial checkout,
make certain all power is disconnected from
the machine to be controlled. Dangerous
voltages may be present along the box wiring
barriers whenever power to the machine control
elements is ON.
Exercise extreme caution whenever machine
control power is or may be present. Always
disconnect power to the machine control
elements before opening the box enclosure.
