Response Times; Fault Diagnosis - IFM Electronic AC016S Instrucciones De Uso Originales

Response times

The response time of the evaluation unit to a safety request is max.
220 ms. Within this period the safety code 0000b (= safe state) is
statically transferred.
Calculation of the total response time
For the calculation of the response time of the total system the
response times of the other components also have to be added (fail-
safe switch, evaluation unit, safety monitor and possibly external
relays).
Example:
For the GM504S fail-safe switch the response time to a safety request
is < 20 ms and for the AC001S safety monitor < 40 ms. The sum of
the individual response times results in the total response time to a
safety request of < 280 ms.
The switching times of external relays also have to be added.

Fault diagnosis

If after power on the evaluation unit is not enabled, a system fault is
assumed. In the easiest case a connected fail-safe switch is not in the
operating range.
Location by means of the indicators
Wiring and sensor faults
One way to locate wiring or sensor faults is the indication of the enable
signal of the connected fail-safe inductive switches (LED 1 yellow, see
operating elements and indicators).
The connected fail-safe switches can be wired pseudo-serially, i.e. the
clock or the enable signal is passed through from the first to the last
connected fail-safe switch.
