PILZ PNOZ m B0 configurable safety control system basic unit

8.2 Project deletion

Select menu RESET PROJECT? And confirm that the items in the base memory will be cleared (but the items in the chip card will not be affected). The next time the device is powered on, it will prompt that there are no items and it needs to be reloaded. This operation is applicable to:

Replaced chip cards with different configurations

Need to completely clear the device for new debugging

The project file is damaged and cannot be overwritten

Technical parameter quick search and replacement suggestions

When suspecting that the hardware itself is damaged, the following key parameters can be referred to for judgment:

Parameter values

System power supply voltage 24V DC (-20%/+25%)

Output power supply voltage 24V DC (-20%/+25%)

Safe output maximum current per channel 2.5A (continuous), transient 12A

Safe output maximum capacitive load of 1 μ F (exceeding this may result in incorrect shutdown)

Safe output shutdown delay (typical) 1 ms

Output disconnect time during self check ≤ 330 μ s

Input delay (maximum) 2 ms

Processing time 30 ms

Working temperature -10 ℃...+70 ℃

Protection level IP20 (to be installed in cabinets above IP54)

Dimensions (height x width x depth) 101.4 x 45 x 120 mm

Weight 235 g

If it is confirmed that there is an internal hardware malfunction in the base unit (such as FAULT being constantly on and unable to be eliminated through project loading, or the knob not responding), the PNOZ m B0 with the same model order number 772100 must be replaced. After replacement, simply insert the original chip card into the new base and load the project, without the need for reconfiguration (provided that the expansion module configuration remains unchanged).
