Figure 7: Connections for safety functions via FS module
For the LSO and LSC signal, the NC contact may only be used for FQM fail safe
units of variant 2 (➭ page 6, Valid device types).
Switching behaviour of ESD input:
●
Input level = high level (standard: +24 V DC)
= No safety operation for Safe ESD function
●
Input signal = low level (0 V DC or input open)
= Safety operation for Safe ESD function
Permissible input voltage range:
●
High level: +24 V DC (–15 %/+20 %)
Current consumption: approx. 1 A, max. 1,2 A
●
Low level: max. 5 V DC
Signal behaviour of the FS ready NO/FS failure NC outputs:
●
Safe ESD function is ready, no fault detected by diagnostic tests is present:
FS ready NO output (NO contact) = closed
FS failure NC output (NC contact) = open
●
Safe ESD function is NOT ready or a fault was detected:
FS ready NO output (NO contact) = open
FS failure NC output (NC contact) = closed
Signal behaviour of LS outputs:
●
End position OPEN reached (XF 19-21 and XF 38-20 terminals) or End pos-
ition CLOSED reachedsignal (XF 22-24 and XF 35-23 terminals), i.e.:
Output at XF 19-21=NO or XF 22-24=NO (NO contact) terminals = closed
Output at XF 38-20=NC or XF 35-23=NC (NC contact) terminals = open
For the LSO and LSC signal, the NC contact may only be used for FQM fail
safe units of variant 2 (➭ page 6, Valid device types).
Permissible load at FS ready NO and LSO/LSC outputs:
●
Voltage range: 5 – 30 V
●
Current range 2 – 100 mA
For the safe signals (FS Ready/FS Failure outputs as well as LSO and LSC),
AUMA recommends the exclusive use of nominal 24 V DC signal voltages.
