Do you have a question about the Pilz 20407-6NL-06 and is the answer not in the manual?

The Pilz PNOZ X2.5P is a safety relay designed for safety-related interruption of safety circuits, housed in an S-99 enclosure and operating on a 24 V DC supply. It complies with EN 60947-5-1, EN 60204-1, and VDE 0113-1, making it suitable for applications involving E-STOP pushbuttons and safety gates. However, it is not suitable for non-contact guards (e.g., ESPE) as dynamic start is not possible. Safety distances in accordance with EN 294 and EN 349 must be observed.

Function Description:

The safety relay ensures a safety-oriented interruption of a safety circuit. Upon application of the operating voltage, the "POWER" LED illuminates. The unit becomes operational when the reset circuit S33-S34 is closed.

Input Circuit Closed (e.g., Emergency Stop button not pressed): Relays K1 and K2 energize and self-retain. The "CH.1" and "CH.2" status indicators illuminate. The safety contacts (23-24/33-34) close. The semiconductor output Y11-Y12 conducts, and its status indicator illuminates.
Input Circuit Opened (e.g., Emergency Stop is pressed): The semiconductor output Y11-Y12 switches off, and its status indicator extinguishes. Relays K1 and K2 de-energize. The "CH.1" and "CH.2" status indicators extinguish. The safety contacts (23-24/33-34) open redundantly.

The safety function remains effective even in the event of a component failure. The correct opening and closing of the safety function relays are automatically tested during each on-off cycle.

Usage Features:

Installation: The safety relay must be panel mounted in an enclosure with a minimum IP54 protection rating. It attaches to a DIN rail (35 mm) via a notch on the rear. For vertical mounting, it should be secured with a fixing bracket.
Operating Modes:
- Single-channel operation: Input wiring according to VDE 0113 part 1 and EN 60204-1. No redundancy in the input circuit. Earth faults in the reset circuit are detected. Earth faults in the Emergency Stop circuit trigger the internal electronic fuse.
- Two-channel operation: Redundancy in the input circuit. Earth faults in the Emergency Stop circuit and shorts across the emergency stop pushbutton are detected.
- Automatic reset: The unit is active as soon as the input circuit is closed.
- Manual reset: The unit is only active when a start button has been pressed.
- Contact Expansion: The number of available contacts can be increased by connecting external contactors/relays.
Wiring Examples: The manual provides connection examples for Emergency Stop wiring, safety gate control, semiconductor output, and contact expansion via external contactors. For automatic reset configurations, external circuitry measures should be used to prevent unintended start-up after power loss.

Maintenance Features:

Troubleshooting:
- Earth Fault: Supply voltage fails, and safety contacts open via an electronic fuse. After removing the fault cause and switching off the operating voltage for approximately 1 minute, the unit will be ready for operation.
- Contact Failure: If contacts are welded, no further activation is possible after the input circuit opens.
- "POWER" LED not illuminated: Indicates a short-circuit or loss of supply voltage.
Fuse Reset: If the internal fuse is triggered (e.g., during a short-circuit test), remove the short circuit and switch off the operating voltage for approximately 1 minute to reset the fuse.
Service Life: The service life graphs indicate the number of switching cycles after which wear-related failures may occur. Wear is primarily caused by electrical load, with mechanical wear being negligible. The PFH value depends on switching frequency and relay output load. If service life graphs are not available, the stated PFH value can be used, as it accounts for the relay's B10d value and other component failure rates.
Contact Protection: To prolong service life, adequate arc suppression must be provided on all output contacts. For capacitive loads, potential current peaks should be considered. For DC contactors, freewheeling diodes should be used for arc suppression. Using semiconductor outputs for switching 24 V DC loads is recommended.
