Coils and contacts
Function block coils initiate the functions of the function
block and monitor the connected safety transmitters.
The contacts of a safety function block confirm the enable
conditions present, selected operating modes or indicate
errors.
Coils
The trigger coil TS..SA activates the timing relay in the safety
circuit diagram.
The trigger coil TS..TR starts the run down of the timing
relay. Used in the safety circuit diagram.
The Stop coil TS..ST interrupts the run down of the timing
relay in the safety circuit diagram.
Parameters Function
Safety activation of the timing relay
TS..SA
Start of the timing relay
TS..TR
Stop of the timing relay
TS..ST
Contacts
The TS..QS contact closes and/or opens in the safety circuit
diagram, according to the operating mode, after the allo-
cated time(s) has expired. For example, the TS..QS closes
with the on-delayed safety timing relay after the allocated
time has expired. It opens again if trigger coils TS..TR or
TS..SA drop out.
If you wire the contact TS..ER in the standard and/or safety
circuit diagram, it indicates the presence of an error by
closing.
