Pilz PSS SB HYD, Basic license - Manual (Page 110)

6-48 Modular Block System: Hydraulic Presses
Standard Function Blocks
- Category 4:
Use two separate switches/contacts, which must be operated
independently. Both switches must close when the safety gate is
closed. A cyclical function test on the gate is not required.
Output parameters
• FG: Enable bit
FG = 0:
Not enabled
FG = 1: Enable occurs if:
the safety gate is closed (
S1 = 1 and S2 = 1), any
errors have been rectified and confirmation has
been given via the
Strt-Signal.
Functions
The operation of SB066 is established via the following input parameters:
• ARSt: Automatic restart
• AuSt: Automatic start when PSS starts up (warm/cold start)
• NFkT: No function test on the gate
The settings at these input parameters are loaded into auxiliary flags when
the PSS is started up and cannot be amended during operation.
Please note that a combination of various settings is possible with these
input parameters (e.g. start-up disabler activated/reset lock activated or
start-up disabler activated/automatic reset etc.). These input parameters
are also used to establish what the operator needs to do should an error
occur (function test and error acknowledgement / reset).
The individual options can be found in the following tables.
