Q: What are the differences between it and the PNOZ X3 series?

A: Although the Pilz 787303 (i.e., PNOZ X2P C) and the PNOZ X3 series both belong to Pilz's classic PNOZ X safety relay family, they differ significantly in output configuration, physical size, and output type.

Q: What are some common malfunctions of this product?

A: When malfunctions occur, in most cases, they are caused by loose external wiring, faulty external safety devices (emergency stop, contactor, etc.), or improper mode settings. It is recommended to first disconnect the power and check the external wiring and components. Only after confirming that these are not the problem should you consider whether the relay itself is damaged.

Q: How to handle the contact adhesion of this relay?

A: Contact adhesion (also known as contact welding) in safety relays is a very serious safety hazard and must be taken seriously. When handling it, it is necessary to clearly distinguish whether the adhesion is to external contacts (emergency stop buttons, contactors, etc.) or to internal contacts of the relay (damage to the PNOZ X2PC itself).
