4. Opsætning og installation
4.1 Montering
The PNOZsigma 750107 is designed for DIN rail mounting. Ensure the DIN rail is securely fastened and provides adequate space for ventilation around the unit.
- Align the top clip of the relay with the top edge of the DIN rail.
- Press the bottom of the relay firmly until it clicks into place on the DIN rail.
- Verify that the relay is securely mounted and does not wobble.
4.2 Ledningsføring
All wiring should be performed with power disconnected. Refer to the terminal markings on the device for correct connections. The unit features plug-in screw terminals for easy and secure wiring.
- Connect the 24 V DC supply voltage to the designated terminals (e.g., A1/A2).
- Connect the input signals from the primary safety device to the input terminals (e.g., X1, X3).
- Connect the safety outputs (N/O and N/C contacts) to the controlled devices or subsequent safety circuits. Ensure correct load ratings are observed.
- Tighten all screw terminals to the recommended torque to prevent loose connections.
5. Betjeningsvejledning
Once properly installed and wired, the PNOZsigma 750107 operates as an expansion module for safety circuits. Its operation is dependent on the signals received from the connected safety-related control component.
- Upon power-up, the device will perform an internal self-test.
- The output contacts will switch according to the state of the input signals and the internal logic of the primary safety device.
- Indicators (if present on the device, e.g., In1, In2, Out, Fault) will provide visual feedback on the operational status and any detected faults.
For detailed operational logic, refer to the documentation of the primary safety-related control component with which this expansion relay is used.
6. Vedligeholdelse
The PNOZsigma 750107 is designed for minimal maintenance. However, regular inspections are recommended to ensure continued safe operation.
- Periodisk visuel inspektion: Check for any signs of physical damage, discoloration, or loose connections.
- Terminaltæthed: Periodically re-check the tightness of all screw terminals, especially after initial installation and during routine maintenance checks.
- Miljøforhold: Sørg for, at driftsmiljøet forbliver inden for de angivne temperatur- og fugtighedsområder for at forhindre for tidlig fejl.
- Rensning: If necessary, clean the exterior of the unit with a soft, dry cloth. Do not use abrasive cleaners or solvents.
No user-serviceable parts are inside the unit. Do not attempt to open or repair the device.
7. Fejlfinding
This section provides basic troubleshooting steps for common issues. For complex problems, contact PILZ technical support.
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Unit not powering on / No indicators | Ingen forsyning voltage; Incorrect wiring; Blown fuse in supply circuit. | Verify 24 V DC supply voltage; Check wiring connections; Inspect and replace fuse if necessary. |
| Outputs not switching | No input signal from primary safety device; Fault in primary safety device; Incorrect output wiring. | Check input signals; Troubleshoot primary safety device; Verify output wiring to load. |
| Fejlindikator aktiv | Internal fault; External wiring fault; Overload on outputs. | Cycle power to reset (if safe); Check all wiring for shorts or open circuits; Verify load current does not exceed 6 Amps. If fault persists, contact support. |
