Parameter setting
Before the system forms a function unit, the parameters are set in the evaluation
unit by the user (number of connected read heads, with or without automatic start,
with or without feedback loop). During this process the read heads are activated.
These configuration parameters are saved in the non-volatile memory in the evalu-
ation unit.
The safety outputs are open during the parameter assignment. The system is in
a safe state.
Important!
Ì
During the parameter setting the following conditions must be met:
Ì
There must be no state change, e.g. opening a safety guard or closing a
further safety guard or a change in the signal on the terminals for the start
button and the feedback circuit.
Ì
The power supply must not be switched off.
Ì
If these conditions are not met, the evaluation unit switches to the safe fault
state (diagnostics LED illuminates) and signals this operating fault with the
STATE LED by 3 short flashes that are repeated every second. The param-
eter setting operation must be repeated.
Ì
The number of parameter setting operations is unlimited. The evaluation unit
can be re-configured as often as required.
Ì
Do not change DIP switches during operation.
To trigger a parameter-setting operation, the user must perform the following ac-
tions in the stipulated order:
1. Prepare for parameter setting
Ì
Switch off power supply U
