Installation and Alignment

3.4 Light Screen Initial Checkout

The initial checkout procedure must be performed by a Qualified

Person (see Section 4.1). It must be performed only after

configuring the System and after connecting the emitter and

receiver per Section 3.3.

• ••••••••••••••• ••••• •••••••••••••• •••••••••••••••••••••••••••••••••••••••••••••••••

Verify that the emitter and receiver both are set to the factory

defaults for initial checkout and optical alignment. (Receiver

factory defaults are for trip output, 2-channel EDM, reduced

resolution OFF, aux output, inverted display OFF, and scan

code 1. Emitter factory defaults are for reset, fault output OFF,

inverted display OFF, and Scan Code 1. See Figure 4-1.)

Initial checkout is performed on two occasions:
• To ensure proper installation when the System is first installed,

and

• To ensure proper System function whenever any maintenance

or modification is performed on the System or on the

machinery being guarded by the System. (See Section 6.1 for

a schedule of required checkouts.)

For the initial checkout, the EZ-SCREEN LP System must be

checked without power being available to the guarded machine.

Final interface connections to the guarded machine cannot

take place until the light screen system has been checked

out.

This may require lockout/tagout procedures (refer to

OSHA1910.147, ANSI Z244-1, or the appropriate standard

for controlling hazardous energy). These connections will be

made after the initial checkout procedure has been successfully

completed.
Verify that:

• Power has been removed from (or is not available to) the

guarded machine, its controls or actuators; and

• The machine control circuit or the interface module is not

connected to the OSSD outputs at this time (permanent

connections will be made later); and

• EDM is configured for no monitoring, per Section 3.5.3.

3.4.1 Initial Power-Up and Optical Alignment

1. Inspect nearby areas for reflective surfaces, including

work pieces and the guarded machine. Reflective surfaces

may cause light beams to reflect around a person in the light

screen, preventing the person from being detected and not

stopping the machine motion. See Section 3.1.6.

Eliminate the reflective surfaces

as possible by relocating

them, painting, masking or roughening them. Remaining

problem reflections will become apparent during step 5.

2. Verify that power is removed from the EZ-SCREEN LP

System and from the guarded machine

and that the OSSD

safety outputs are not connected. Remove all obstructions

from the light screen.

Leaving power to the guarded machine OFF, make power

and earth ground connections on both the emitter and

receiver cables (see Figures 3-23 to 3-26) and then power up

the EZ-SCREEN LP System (only).
Verify that input power is present to both emitter and

receiver.

At least one indicator on both emitter and receiver

should be ON and the start-up sequence should cycle.

3. Observe both the emitter and the receiver Status indicators

and the receiver Zone indicators to determine light screen

alignment status:

•

An Emitter Lockout condition

– the emitter Status indicator

single-flashing Red; the receiver Status indicator ON Red,

7-segment display reads “CH1”. Proceed to Section 5 for

diagnostic information.

•

A Receiver Lockout condition

– the emitter Status indicator

ON Green; the receiver Status indicator single-flashing Red,

Zone and Reset indicators OFF. Proceed to Section 5 for

diagnostic information.

•

Normal operating mode

(emitter) – the Status indicator ON

Green.

•

A Latch condition

(receiver), all optical beams clear – the

receiver Status indicator ON Red and the Reset indicator

double-flashing Yellow; Zone indicators ON Green. When the

receiver is configured for Latch Output, the outputs are ON

only when all beams are clear and after a manual reset (see

Section 1.4.8). If a reset routine can cause a Clear (Run)

condition, optimize the alignment as described in step 4. If

a Clear (Run) condition can not be achieved, see “Blocked

condition” below.

•

A Clear (Run) condition

(receiver) – the Status indicator ON

Green (or flashing Green if reduced resolution is enabled),

and the Reset indicator ON Yellow. All Zone indicators ON

Green.

•

A Blocked condition

(receiver) – the Status indicator ON

Red, the yellow Reset indicator ON, and one or more Zone

indicator(s) ON Red, identifying the location of the blocked

beams, and the number of blocked beams will be displayed.

Proceed to step #4.

NOTE: If beam 1 is blocked, Zone indicator 1 will be Red and

all others OFF. (Beam 1 provides the synchronization

signal.)

NOTE: If the emitter Test input is open, the receiver’s

7-segment Display will indicate the total number

of beams in the system (minus one) and all Zone

indicators will be Red (except for 14-beam systems,

where Zone 1 indicator will be Green).
