Solid State Device - Reer MZERO Installation, Use And Maintenance Manual

Power-on test: If selected, enables the power-on test of the device. This test requires activation
and de-activation of the device in order to run a complete functional check and enable the Output
terminal. This test is required only at machine start-up (power-on of the module).
Filter (ms): Permits filtering of signals from the device. This filter can be set to between 3 and 250
ms and eliminates any rebounds on the contacts. The duration of the filter affects calculation of
module total response time.
With simultaneity: If selected, activates control of simultaneity between switching of signals from
the device.
Simultaneity (ms): Is active only if the previous parameter is enabled. Determines the maximum
permissible time (ms) between switching of two different signals from the sensor.
Enable Error Out: If selected reports a fault detected by the function block.
Item description: Permits insertion of a descriptive text of the function of the component. This text
will be displayed in the top part of the symbol.

SOLID STATE DEVICE

The SOLID STATE DEVICE functional block checks the status
of the Inx inputs. If the inputs are at 24VDC, the Output will
be 1 (TRUE), otherwise the OUTPUT will be 0 (FALSE).
Parameters
Manual Reset: If selected, enables the reset request after
each safety function activaction. Otherwise, enabling of the
output follows directly the conditions of the inputs. Reset
may be of two types: Manual and Monitored. Selecting the
Manual option, only transition of the signal from 0 to 1 is
checked. If Monitored is selected, double transition from 0
to 1 and return to 0 is checked.
t = 250ms

If Reset is enabled, the input consecutive to those used by the functional block must be used.
For example: if inputs 1 and 2 are used for the functional block, input 3 must be used for
Reset.
Power-on test: If selected, enables the power-on test of the safety device. This test requires
activation and de-activation of the device in order to run a complete functional check and enable
the Output terminal. This test is required only at machine start-up (power-on of the module).
Filter (ms): Permits filtering of signals from the safety device. This filter can be set to between 3
and 250 ms and eliminates any rebounds on the contacts. The duration of the filter affects
calculation of module total response time.
Simultaneity (ms): always active. Determines the maximum permissible time (ms) between
switching of the various signals from the external contacts of the device.
Enable Error Out: If selected reports a fault detected by the function block.
