Product Information

Full details

The Schneider Electric Harmony XAC Pendant Pushbutton Box (XACA2073) is designed for industrial hoist and crane operations requiring reliable two-speed control and immediate safety shutdown. It offers robust IP65 protection for harsh environments, an ergonomic pistol grip for single-handed operation, and clear markings for raise, lower, and emergency stop functions. A key benefit is its ability to enhance operational safety and efficiency in demanding applications. However, its specific functionality is geared towards two-speed motor control, which may not suit all lifting applications.

Extended Product Information

FAQs

What is the IP rating of this pendant station?

The pendant station has an IP65 rating, which means it is protected against dust ingress and low-pressure water jets, making it suitable for harsh industrial environments.

Can this unit be used for single-speed motors?

While it can be wired for single-speed operation by only using one set of contacts, its primary design and benefit are for controlling two-speed hoist motors.

What is the maximum current and voltage rating?

The pendant station supports a maximum current of 3A and a voltage rating of up to 600V.

How do I reset the emergency stop button?

The emergency stop button is typically a twist-to-release or pull-to-release type. Rotate or pull the button outward to reset it and restore power to the controlled equipment.

What type of terminals are used for wiring?

It features screw clamp terminals, which allow for secure and reliable connections for wires up to 2.5mm².

What is the operating temperature range?

The device can operate effectively within an ambient temperature range of -25°C to +70°C.

How does the two-speed functionality work?

Each push button (raise and lower) has two normally open (NO) contacts. One set of contacts is for the slow speed, and the other is for the fast speed, allowing for variable motor control.

Troubleshooting

Push button not responding

Verify that the device is properly wired according to the schematic. Check for continuity across the relevant contacts using a multimeter. Ensure the control circuit has power.

Emergency stop button does not function

Inspect the emergency stop button's NC contact for damage or obstruction. Ensure the button is correctly wired into the safety circuit. Test continuity of the NC contact when the button is in the released state.

Two-speed control is erratic or fails

Confirm that the wiring for both the slow and fast speed contacts is correct. Check the motor control relay or contactor for proper operation. Ensure the control voltage is within the specified range.

Unit appears damaged or enclosure is compromised

Do not use the device if the enclosure is cracked or damaged, as this compromises the IP65 rating. Replace the unit if significant physical damage is observed.

Setup, Compatibility & Care

Setup:

  1. Cable Entry: Utilize the rubber sleeve for stepped cable entry, accommodating cable diameters between 7mm and 15mm.
  2. Wiring: Connect wires to the screw clamp terminals. Ensure connections are secure. Refer to the internal wiring diagram for correct terminal assignment for each button.
  3. Mounting: The pistol grip design allows for easy handling and positioning during operation.

Compatibility:

  • This unit is specifically designed for controlling two-speed hoist motors.
  • It is compatible with systems requiring a 3A maximum current and up to 600V voltage rating.
  • The standard push button and emergency stop configurations are common in industrial control systems.

Care:

  • Cleaning: Clean the exterior with a damp, soft cloth. Avoid using harsh solvents or abrasive cleaners, as they can damage the enclosure and markings.
  • Inspection: Regularly inspect the emergency stop button, push buttons, and enclosure for any signs of damage. Ensure the emergency stop can be easily activated and reset.
  • Connections: Periodically check the security of the screw clamp terminal connections to prevent loose wiring.
