Chip card
The set parameters, the device ID and the check sum for device configuration are stored on
the chip card (for further information see chapter entitled "Commissioning", under "Use chip
card [ 913]").
Reaction time
The reaction time (see Technical details [ 934]) of the PNOZ s50 is the time between a
signal changing at the inputs for fast (Y10/Y11, Y20/Y21) or slow shutdown (S35, S36) and
the signal changing at the outputs of the power circuit (O1+/O1-, O2+/O2-). The reaction
time takes into account the input filter time, temperature drift and spread of components.
To determine the plant's overall reaction times, the corresponding internal processing times
of the higher level safety control system and connected load must also be considered.
Installation
General installation guidelines
Control cabinet installation
} The unit should be installed in a control cabinet with a protection type of at least IP54.
} Fit the device to a horizontal DIN rail. The venting slots must face upwards and down-
wards. Other mounting positions could destroy the device.
} Use the locking element on the rear of the device to attach it to the DIN rail.
} Push the device upwards or downwards before lifting it from the DIN rail.
