Banner AG4 Series Safety Laser Scanner
Product Manual P/N 144924 05/2009 7
1Overview
The Banner AG4 is an optical, two-dimensional measuring Safety Laser Scanner.
The Scanner emits periodic light pulses via a rotating deflection unit. The light pulses reflect back from objects in the field and are then detected
by the Scanner receiver. The Scanner calculates the precise position of the obstruction from the light travel time and the angle of the deflection
unit when the pulse was emitted. If the obstruction is within the user-defined protective field (PF), the Scanner switches the safety outputs OFF.
Only when the PF is free of obstructions does the Scanner turn the safety outputs back ON, either automatically or following a manual restart
(reset) signal, depending on the operating mode.

1.12 Providing the machine operator with information
WARNING . . . SCANNER OPERATION ON POWER-UP
It is the responsibility of the person who configures, installs, and/or maintains the AG4 Scanner to assess what safeguarding
devices and methods are appropriate for any given machine or application and to be aware that the power-up behavior of this
Scanner application may not be obvious to the machine operator.
The machine manufacturer must inform the machine operator of the requirement for the safe operation of the machine with the Scanner. This
also includes providing the necessary instructions needed by the operator. The operational instruction materials may never describe a situation
that could expose an operator to a hazard.
1.13 Basic Operation Functions
The AG4 must be configured by a Qualified Person to ensure that people who are exposed to potentially dangerous machines, are adequately
protected. The AG4 functions are described in this section.
1.14 Start/restart (reset) interlock
WARNING . . . START/RESTART (RESET) PUSH BUTTON LOCATION
The system Start/restart (Reset) push button must be accessible only from outside, and in full view of, the hazardous
area. Reset switches must also be out of reach from within the safeguarded space, and must be protected against
unauthorized or inadvertent operation (via rings, guards, key or other means). If any areas are not visible from the reset
switch, additional means of safeguarding must be provided. Failure to do so could result in serious bodily injury or death.
The start/restart (reset) interlock has two functions:
Start interlock
Restart interlock
This interlock function is used to enable the machine’s normal start command. Actuating (cycling) this input of the AG4 should not cause
hazardous motion or a hazardous situation. After clearing the start/restart interlock of the AG4, a second action by the operator (e.g., actuating
the machine cycle start button) is required to begin or resume the machine’s operation.
Using start/restart (reset) interlock
In addition to the Scanner the start/restart button must also be installed. The machine operator causes the Scanner outputs to turn on
when the button or switch is activated.
Position the start/restart button outside the danger zone so that it cannot be activated from the protective field and danger zones. The
operator must be able to see all danger zones from this position.
Identify the zone to be reset by the start/restart button so that it's meaning is clear and easy to understand.
Ensure that nobody is in the danger zone before pressing the start/restart button.
1.14.1 Start interlock
The start interlock function prevents the machine from starting automatically after power is initially applied or after the power supply returns.
The Scanner outputs will turn on only after the start/restart button is activated.
Product Manual P/N 144924 05/2009 13

Banner AG4 Series Safety Laser Scanner
14 P/N 144924 05/2009 Product Manual
1.14.2 Restart interlock - Manual Restart (reset) when PF is clear
The restart interlock prevents the machine from starting automatically, as soon as the PF is clear again. The restart interlock function always
includes the start interlock function (if someone is detected in the protective field and then power is lost and comes back on again then a single
button activation will cause the Scanner outputs to turn on).
Scanner outputs turn on only when the PF is clear and the start/restart button is pressed.
1.15 Start test
The start test function requires the operator to interrupt and then clear the PF with a test rod once after the Scanner is powered up. Only then
will the Scanner outputs turn on so the machine can be started.
When the start test is combined with the automatic restart function, the start test serves as an automatic start/restart signal.
1.16 Automatic start/restart
The automatic start/restart function enables the Scanner safety outputs to turn on as soon as power is applied if and when the PF is clear.
The automatic start/restart function can be used under the following conditions.
The automatic start/restart function is taken over by a downstream safety component of the machine control system.
or
It is not otherwise possible to access the hazard
Allow for an optical and/or acoustic start warning.
WARNING . . . AUTOMATIC START/RESTART
When the AG4 Scanner is configured for Automatic Start/Restart operation, the sensor will turn its safety outputs on as soon
as the protective field is clear. If the application requires a manual start/restart signal then the Start/restart Interlock function
must be configured for this manual Start/restart signal. Failure to do so could cause a machine to operate in an
unexpected way at power-up or after temporary power interruptions.
1.17 Dust suppression
The dust suppression function increases the availability of the Scanner when small particles are in the air, e.g. material chips or insects.
Deactivate the dust suppression function when the Scanner must detect extremely fast or small objects in the application.
1.18 Field Pairs - Independently activated protective and warning fields
WARNING . . . FIELD PAIR SWITCHOVER TO FIELD PAIR 8 DEACTIVATES THE MONITORING
FUNCTION
When field pair control state 8 is used, no protective or warning fields are being monitored and the OSSDs remain ON.
Never start the Scanner with field pair 8.
Only use field pair 8 when there is no danger for people present, e.g. during machine cycles where there is no
danger to the operating staff.
The Scanner is capable of activating 1 of 7 field pairs at any given time. This means that it is possible to have only one field pair, in a group of
multiple field pairs, that has safety output (OSSD) control authority. This operation is useful in cases where, during times when there is no
hazard access via the deactivated fields, objects can move freely in and out of these areas without the OSSDs turning off. A field pair is defined
as the combined area of a single PF & WF pair.

Banner AG4 Series Safety Laser Scanner
Once the Scanner is configured, switching over or “activating” the individual field pairs is controlled by the 4 FP input lines on the X1 plug (See
table 1 Input Logic for Field Pair Control). The rules for when each FP can be deactivated must be thoroughly analyzed during the machine risk
assessment. Machine braking distances, system response time, machine stop time and other factors that influence the Separation Distance
calculations must be considered in order to use the Field Pair switchover function safely.
WARNING . . . PROTECTIVE FIELD PAIR SWITCHING
Field Pair Switching is used to temporarily suspend or change the safety output control authority of a Protective/warning field
pair and must be performed in a way that does not put personnel at risk. Follow the guidelines listed here when changing the
active Field Pair:
Use one or more diverse redundant sensors or switches to initiate a Field Pair change
Make sure (via supplemental safe guarding) that an inactive Protective Field Pair does not create access to a hazard
point.
WARNING . . . FIELD PAIR SWITCHOVER CONTROL STATE 8
Field Pair switchover logic control state 8 deactivates the entire Protective Field monitoring function of the Scanner. This
creates a condition where the Scanner safety outputs (OSSDs) are turned ON even if a person enters the potentially
hazardous area.
Only use Field Pair switchover state 8 when there is no hazard exposure for personnel.
Never start the Scanner with switchover state 8 active.
Failure to follow these recommendations can potentially create a dangerous condition that may lead to serious injury
or death.
Product Manual P/N 144924 05/2009 15

Banner AG4 Series Safety Laser Scanner
Field pair switchover control
The FP switchover sequence performed by the control system must agree with the Scanner’s operational settings which are established during
configuration.
NOTE: When switching over between field pairs, keep the first field pair active while activating the second. Do not deactivate one field
pair before activating the second; if no field pairs are active, a lockout will occur.

1.19 Reference contour (surface) monitoring
The reference contour (surface) monitoring function prevents unintentional misalignment and deliberate manipulation of the Scanner. If the
protective field contains a reference contour (surface), the Scanner monitors both the PF (for object intrusion) and the reference surface (for
safety integrity). If the distance between the sensor and the reference surfaces change from the original configuration, the sensor will detect this
and will switch the OSSDs to off.
