PVTHSD, EMAS, crane pendant control spare part, push-button head, single-speed

PVTHSD is a crane pendant control spare part made by EMAS. This page describes a specific order variant, not just a general product line.

In industrial automation the exact order code is essential: similar-looking variants may differ in contacts, operating element, degree of protection, electrical parameters or compatibility. Catalogue parameters, recommended use and checkpoints before ordering are therefore listed separately below.

Operating principle

The spare part restores a specific function of the PV control station without replacing the whole enclosure.

Typical applications

Used when servicing push-button heads or contact blocks of pendant controls.

Technical specifications

Mounting and wiring

Before replacement, disconnect the equipment from the power supply and verify the exact position and type of the original part. After replacement, carry out a functional test of all button steps.

Before commissioning, check the mechanical operation, electrical function and secure fastening. When replacing an original part, also compare the orientation of the cable, connector or actuator and the available mounting space.

How to choose the right variant

The order code must match the required START/STOP function or the single-speed/two-speed button.

Compatibility and replacement

When replacing, compare the original order code, contact function, mechanical design, degree of protection and electrical load. For accessories, the exact compatible series must also be verified. If a parameter is not stated in the available source data, it is not assumed in this description.

Operation, inspection and service

After replacement, check the mechanical operation and electrical switching of the contacts, especially for two-step buttons.

After replacement or a change of mechanical setting, always carry out a functional test in the real working range of the machine. For elements that affect stopping or interlocking of the machine, also test the related control logic.

Source of technical data

Technical data were added from the user-supplied EMAS Product Overview catalogue, edition 57, catalogue page 109, and from the e-shop source export.

The catalogue and source text was used for the parameters of the specific variant. Technical values not documented in the available sources are not added to the description.

FAQ

What kind of product is PVTHSD?
PVTHSD is a crane pendant control spare part made by EMAS. The exact design and parameters of this variant are listed in the technical table.

How to verify that PVTHSD is the correct variant?
Compare the complete order number, product function, mechanical design, electrical parameters and compatibility with the specific assembly.

Why is a similar appearance or name not enough?
For industrial components, a small change in the code can mean a different contact, actuator, voltage, connector or a different function.

What should be checked before ordering?
Order code, contacts, mechanical design, degree of protection, electrical parameters and connection method. For accessories also the compatible series.

How to proceed when replacing the original part?
First copy the complete code of the original part. Then compare the function, dimensions, wiring and mechanical method of operation.

Can the product be used in another application?
Yes, but only if the technical and mechanical conditions match. The same product line by itself does not guarantee interchangeability.

How to install the product correctly?
Observe the mechanical design, direction of action and electrical wiring according to the specific assembly.

How often should the product be checked?
The interval depends on the operating intensity and environment. Always check its condition during regular machine servicing.

What to do if compatibility is unclear?
Compare the order number and documentation of the original assembly; do not select by name alone.

Where are the source parameters stated?
For EMAS products, the technical data were added from the EMAS Product Overview catalogue edition 57 and from the e-shop source export.
