Description of Parameters and their Settings
P01.07
Reserved for future applications
P01.08
Sensor monitoring on/off
Range: 0 .. 2
If the sensor is monitored, the fault alarm may be latched until it is reset.
Setting:
0 : off (sensor monitor disabled)
1 : on
2 : on, latched
Note:
If P01.08 set to 0, Step P01.09 is meaningless.
P01.09
Mode of sensor monitoring
Range: 0 .. 5
Setting:
0 : Without monitoring
1 : Checks sensor current drain
2 : Checks signal voltage level volt sensor at stand still
3 : Current drain and voltage level
4 : Checks signal voltage level inductive sensor at stand still
5 : Checks signal voltage level NAMUR sensor at stand still
Note:
- Selection of Setting 0 makes Step P01.08 meaningless.
- The voltage level check is only possible with Braun sensor type A5S...
In this instance a signal lead break between sensor and D521 will be
detected at stand still of the machine. This check requires a jumper
between terminals 14 and 16. Maximum admissible signal voltage is
30Vdc.
- For Ex Applications with SIL2 requirements (with A5S1.. and D461)
P01.09 must be set to 2.
- For Non-Ex Applications with SIL2 requirements (with A5S0)
P01.09 must be set to 3.
P01.10
Fix value 001
