Effect on the safety function of the performance variations
The limit of performance degradation in order to avoid the loss of the safety function is ± 5% of the span at room
temperature.
SRP/CS interface and protection devices
The interface to controller can be:
• the multi-polar cable outlet with conduit output type ½ 14-NPT as illustrated in Fig. 7.2, where are also pointed
out the connections (2 wires connection current amplified).
Response time
The response time of the safety function is:
Analog out = 250 ms
The response time of safety function is considered with Damping filter = 0
The response time changes accordingly considering a Damping filter value other than 0, summing the value of
Damping filter to 250ms
The response time in case of a detected fault is:
Analog out = 500 ms
The response time in case of a detected fault is not affected by Damping filter value
Suspension of the safety function
In H series transducer it's not allowed any suspension or bypass of the safety function.
Indications and alarms
The HMF/HWF series have an amplified 4...20mA analog electrical output
In Fig. 10.1 are shown the significant values of the outputs in case of analog signal:
In Tab. 10.2 are pointed out the failures, their effects on the output signal and how to reset them:
Failure
Supply wire broken
Sensor unconnected
Supply system broken
