Question 1

What is the difference between XX-WL01 and XX-WL02?

Accepted Answer

XX-WL01 provides five-colour signalling, while XX-WL02 uses three layers and three colours. Selection depends on how many machine conditions need to be distinguished and how the indication should be presented. Matching the lamp format to the control concept helps operators recognise status quickly and avoids adding signalling complexity that the process does not need.

Question 2

When is the five-colour XX-WL01 useful?

Accepted Answer

Choose a five-colour concept when the machine needs to communicate several clearly defined states, such as operating, attention required, fault, setup or a process-specific request. Assign the meanings consistently with the plant's signalling convention. This can provide useful status information at a glance while leaving detailed diagnosis to the HMI.

Question 3

When should I choose the three-layer XX-WL02?

Accepted Answer

The three-layer format suits applications with three principal status categories and a preference for vertically separated indications. It can provide a straightforward visual arrangement for machines with simple state logic. Define the required simultaneous or priority behaviour with the control design and confirm it against the selected lamp's wiring instructions.

Question 4

How do signal lights add value to an HMI workstation?

Accepted Answer

They extend status visibility beyond the screen. Personnel approaching the machine can recognise an indicated condition without first reading the HMI, which can help prioritise attention across several stations. The best result comes from a small set of meaningful signals with clear operator actions and a mounting position visible from the normal working area.

Question 5

What mounting interface do the XX-WL lamps use?

Accepted Answer

The current XX-WL01 and XX-WL02 product specifications list an M22 x 1.5 interface. Confirm the receiving part's thread or mounting-hole arrangement, available engagement and sealing details against the drawing. Specifying the complete lamp connection avoids discovering during installation that a similarly sized cover has a different thread or fixing method.

Question 6

Can the lamps be mounted on XINDUX support arm systems?

Accepted Answer

Yes, a suitable warning-lamp cover can provide the connection within the selected arm series. Match the lamp's M22 x 1.5 interface to the actual cover drawing. Some published cover descriptions specify M18 x 1.5, so the cover and lamp should be ordered as a verified combination, including any required machining or adapter.

Question 7

What is the purpose of an XX-TA series warning-lamp cover?

Accepted Answer

It provides the mechanical mounting location at the support arm corner module and a route for the lamp wiring into the system. Selecting the correct cover keeps the indication integrated with the operator station and can reduce separate brackets. The ordered cover must suit both the arm series and the chosen lamp interface.

Question 8

What space should be reserved for installation?

Accepted Answer

The current product pages list an overall envelope of 122 mm height and 55 mm diameter, with a 65 mm illuminated section. Check the selected model's drawing and add space for fastening, cable termination and visibility. Including the lamp envelope in the station layout helps avoid interference with guards, doors or overhead structures.

Question 9

Which electrical supply should be specified?

Accepted Answer

The product wiring references identify 24 V DC control connections. Confirm the operating supply, tolerance, polarity and connection diagram for the exact ordered variant before wiring. In particular, the listed insulation voltage of 300 V describes insulation characteristics; it is not the operating supply to be applied to the lamp.

Question 10

Can a PLC operate the lamp directly?

Accepted Answer

Direct operation depends on the lamp's input arrangement and current demand matching the PLC output. Check source or sink behaviour, channel current limits, common connection and any simultaneous loads. Where the interface does not match, specify an appropriate intermediate device. This assessment avoids output overloads and gives the controls engineer a defined connection scheme.

Question 11

How should the return conductor be connected?

Accepted Answer

Use the exact wiring diagram supplied for the ordered lamp and identify the supply return separately from the switched control inputs. Confirm terminal designations before energising the device. Clear identification is especially useful where website wording uses positive and negative supply labels that could otherwise be interpreted as a different voltage arrangement.

Question 12

Is an audible warning function available?

Accepted Answer

The XX-WL product information references a buzzer control line. Confirm the buzzer function and acoustic specification for the selected variant, including how it is controlled. Combining sound with light can attract attention where the lamp is outside the operator's view, while separate control can help keep audible warnings relevant to the process.

Question 13

Are flashing or other signalling modes available?

Accepted Answer

Specify the required behaviour when selecting the lamp: steady indication, flashing and any other modes need to be confirmed for the exact variant and control arrangement. Avoid assuming that features shown for other warning-lamp families apply to XX-WL01 or XX-WL02. A defined mode and priority sequence make the visual signal easier to interpret consistently.

Question 14

What protection rating is specified?

Accepted Answer

Both XX-WL product pages specify IP65. The installation must preserve the lamp's seal and the protection of the receiving enclosure or arm cover. Check the mounting seal, cable entry and environmental exposure together. This allows the indicator to be included in a protected operator station without overlooking the interface through which it is mounted.

Question 15

How should the operating temperature range be selected?

Accepted Answer

Specify the lowest and highest ambient temperatures at the lamp location and obtain the range for the exact ordered variant. Include local heat from nearby equipment or direct sunlight where relevant. Variant-specific confirmation is necessary because the two current product pages list different lower temperature limits; one range should not be applied across the complete family.

Question 16

What service-life information is available?

Accepted Answer

The current XX-WL pages list an electrical life of 10,000 hours. Use that figure with the stated operating conditions and confirm the applicable service-life basis where it matters to the project. It is a product-life reference rather than a guaranteed maintenance interval for every environment or operating pattern.

Question 17

How should I choose the lamp's mounting position?

Accepted Answer

Check visibility from the normal operating position, access route and other locations where personnel need to recognise the signal. Account for guards, equipment, ambient lighting and HMI movement. Locating the lamp with the complete station in view can improve the usefulness of the indication without adding more lights or increasing signal complexity.

Question 18

Can a signal light perform a machine safety function?

Accepted Answer

The XX-WL products provide status indication. Any safety-related function requires an appropriate system design and evidence for the devices involved; visual indication alone does not establish it. The lamp can communicate conditions generated by the machine control, while the protective function remains defined by the machine's safety system.

Question 19

How can OEMs standardise signalling across a machine range?

Accepted Answer

Define a common state table, colour meaning, buzzer behaviour, wiring allocation and mounting interface. Then select the lamp variant that supports each machine's requirements. A consistent signalling concept can reduce operator training effort, simplify control documentation and make replacement parts easier to manage across installed machines.

Question 20

What information is needed to quote the correct lamp and mounting kit?

Accepted Answer

Provide the required colours and state logic, supply and control-output details, buzzer requirement, environment and preferred mounting location. Identify the arm series or enclosure interface and the quantity. Quoting the lamp, matched cover and necessary connection parts together can reduce installation work and avoid mismatched mechanical or electrical interfaces.
