EZ-SCREEN LP
Instruction Manual
Cascadeable EZ-SCREEN
To change (relocate) or clear (remove) previous fixed blanking, when:
• Obstruction is relocated or cleared with EZ-SCREEN LP power OFF.
• Clearing an Error Code 10 “Fixed Blanking Error” (begin at step #5, with the programming key switch in the Run position)
• Clearing an Error Code 12 “Timeout Expired” (begin at step #6, with the programming key switch in the Program position)
Action Indication Comments
1 Remove power from EZ-SCREEN LP.
2 Locate or relocate the obstruction
(e.g., tooling, fixturing, etc.) in the
defined area and secure it, or if
clearing the fixed blanked area,
remove all obstructions.
3 Reapply power to the EZ-SCREEN
LP system. EZA-RBK-1: rapid flashing
Receiver: Power-up Test Sequence. All LEDs turn ON momentarily during
the Power-up Display Test Sequence.
4 An Error code 10 is generated when
one or more of the currently fixed
blanked beams become clear. EZA-RBK-1: OFF
Receiver: display flashes “1”, “0”, status
LED flashes red.
5 Place the programming key switch
in the Program position (clockwise)
until step 8. EZA-RBK-1: OFF
Receiver: display flashes “1”, “0”, status
LED flashes red.
6 Perform a valid reset (close the reset
switch for ¼ to 2 seconds, then open
it). EZA-RBK-1: rapid flashing, then steady ON
Receiver: display sequences between “P”
“F” “A” and the number of blocked beams. • EZA-RBK-1 indicator flashes rapidly
to indicate the reset is in process.
• The timer resets to 10 minutes.
• Cascade systems: the first receiver
locks out in an Error Code 13.
7 If necessary, locate or relocate the
obstruction (e.g., tooling, fixturing,
etc.) in the defined area and secure.
If clearing the fixed blanked area,
remove all obstructions. EZA-RBK-1: steady ON
Receiver: display sequences between “P”
“F” “A” and the number of blocked beams. If an Error Code 12 occurs
(programming time out), repeat
step #6 above (do not return the
programming key switch to the RUN
position).
8 Return the programming key
switch to the Run position (counter-
clockwise). EZA-RBK-1: slowly flashes for
approximately 5 seconds
Receiver: display indicates “P” “F” “C” This saves the new fixed blanking
configuration.
9A Standalone (one sensor pair)
Trip Output: the OSSDs turn ON.
Latch Output: After the EZA-RBK-1
indicator turns OFF, a valid reset
sequence is required. EZA-RBK-1: OFF
Receiver: display indicates normal
operation.
9B Cascade system (multiple
connected emitter-receiver pairs),
after the EZA-RBK-1 indicator turns
OFF:
Trip Output: Perform a single valid
reset, and the OSSDs will turn ON.
Latch Output: Two valid reset
sequences are required to turn ON
the OSSDs. Pause between the
reset actuations to allow the Error
code 13 to clear. EZA-RBK-1: OFF
1st Receiver: Error Code 13.
Cascaded Receiver(s): display indicates
normal operation. • A reset is required to clear the Error
Code 13 on the first receiver (i.e., the
receiver connected to the machine
control).
• EZA-RBK-1 indicator ON when the
reset is actuated (closed) in normal
Run mode, flashes rapidly when
reset is in process.
• Latch Output: the second reset is
required to clear the latch.
