Monitoring Interval For Mandatory Testing - Siemens SIMOCODE pro Operating Manual

4.3.9

Monitoring interval for mandatory testing

Description
Function for monitoring the interval between the connection and the tripping of the enabling
circuit (actuator tripping). The monitoring time starts anew every time the enabling circuit
closes. This function supports you in complying with test intervals that require verification.
In the enabling circuit of the DM-F Local and the DM-F PROFIsafe, relay contacts perform
safety-related tripping. Whether the relay contacts of the enabling circuit actually open or not,
can only be established via a change in the switching state of the contacts.
The "Monitoring interval for mandatory testing" function supports the system operator in the
monitoring of the time that has elapsed since the last connection of the enabling circuit.
When the adjustable limit has been reached, the set reaction follows (disabled, signal, warn;
see response). This is logged in the event memory.
This monitoring function is an organizational measure that supports the system operator in
detecting faults by conducting regular tests, see information in the operating instructions on
regularly testing the function of a safety device. The monitoring function itself need not be
safety-related.
Note
The function "Time until test" is not a safety-related function
