5.3 Start level
Alternatively:
auto-start or manual start (falling edge)
Optional:
feedback circuit (EDM), start-up testing
Start-up test
After switching on the supply voltage again the protective device must
first be opened and closed again before the enable can be activated
with the start/RESET button.
5.4 Sensor level
18 safe digital inputs
Selectable:
1-channel of 2-channel, equivalent,
antivalent or deactivated.
Optional condition: Short circuit recognition,
discrepancy monitoring
2 safe analogue inputs
2 analogue safe 1-channel inputs each with 4 adjustable limit values
or 1 analogue safe 2-channel input with 4 adjustable limit values and
adjustable monitoring of the percentage (of maximum value = 4095)
channel deviation.
Discrepancy monitoring
After a request for a 2-channel protection device that is carried out by
only one of the input channels, both input channels must be opened
and closed again before the release with the START / RESET button
can be activated.
Cross-wire detection
Measure for detecting short circuits between the input channels for
2-channel operation. The cross-circuit detection is achieved here by
the use of clock outputs T0 ... T2 using floating safety sensors. The
assignment of the clock outputs to the inputs is fixed. The setting takes
place in the inputs menu.
To reach cat. 4 / PL e / SIL CL 3, cross-circuit detection
must be enabled in floating safety sensors.

Analogue limit values
The limit values are set with a number of between 0 to 4095.
The following conversion applies:
Limit value = Voltage [V] x 337
