Harmony XV4 Tower Lights

Introduction

Schneider Electric’s Harmony XV4 is a modular LED tower-light series for industrial signaling. Built around a Ø40 mm format, the series combines clear or colored lens options with steady and blinking operating modes to provide visible machine or process-status indication. Its specified IP65 protection, Type 12 environmental rating, and operating temperature range of -10°C to +50°C make it relevant to industrial control installations where signaling devices may be exposed to dust, moisture, vibration, and changing ambient conditions.

What it does

Harmony XV4 tower lights provide visual status indication through modular LED light elements. Depending on the installation and selected configuration, the lights can operate in steady or blinking modes, allowing an assembly or system to communicate different operating states visually.

The series uses a white body and high-visibility clear or colored lenses. LED operating life is specified at up to 50,000 hours, supporting long-term signaling use without the lamp-replacement requirements associated with conventional light sources.

The mechanical and environmental specifications are aimed at industrial deployments. Harmony XV4 units are rated IP65 and Type 12, with a storage temperature range of -35°C to +70°C. They are also specified for in-operation shock resistance of 20 gn for 11 ms and vibration resistance of 6 gn at ±0.5 mm across 10 Hz to 500 Hz.

Applications

Typical uses that follow from the series’ signaling function include:

• Machine-state indication on industrial equipment
• Production-line or workstation status signaling
• Process-condition indication on control panels
• Visual alarms for equipment requiring operator attention
• Status indication in machinery or enclosures exposed to industrial environmental conditions

Design considerations

The Harmony XV4 series has a Ø40 mm form factor and supports universal mounting, so mechanical placement and visibility should be considered as part of the installation design. Select clear or colored lens options and steady or blinking operation according to the status states that need to be communicated.

For installations in demanding environments, confirm that the expected ambient temperature remains within the specified -10°C to +50°C operating range. The IP65 and Type 12 ratings, together with the stated shock and vibration resistance, are relevant when locating the tower light on machinery or equipment subject to washdown-adjacent dust and moisture exposure, vibration, or transient mechanical shock.

Accessory compatibility with Schneider Electric XVB7, XV6, and XV4 ranges may also be useful when extending or maintaining an existing signaling installation. Applicable standards and markings listed for the series include IEC, CUL, CCC, and CE marking.
