5.9 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 carry out safety-oriented tripping. Whether the relay contacts of
the enabling circuit really 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
(deactivated, signaling, warning; 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 carrying out 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-oriented.
Note:
The function "Time until test" is not safety-oriented.
