Modular Block System: Hydraulic Presses 6-61
Example of a suitable signal formation: set ARSt to “1” using
the enable signal and back to “0” using the OU signal (TDC) or
the signal for downward movement. Above all, make sure that
input parameter
ARSt remains set at a static “0” during the
potentially dangerous movement. This means that the input
parameter will also remain set at “0” if the protected field is
broken.
• STyp: This input parameter establishes the start-up procedure in
cycle mode. This setting effects:
- PSS start-up in “single break” and “double break” mode
- The change of mode from “Aus” (
Off = 1) to “single break
( SBrK = 1) or “double break” ( DBrK = 1) mode.
- 0/1-pulse edge at RUN in “single break” (SBrK = 1) or
“double break” (DBrK = 1) mode (see also under “Cycle
modes”).
STyp = 0: The sequence is fixed as follows:
First break the protected field and then press the
reset button (input parameter
RSET).
STyp = 1: The sequence is fixed as follows:
First press the reset button (input parameter
RSET) and then break the protected field.
• Test: Test input (simulating a break in the protected field)
This input parameter is only effective in “Guard only” mode
(see also under “Function”).
Test = 0/1 pulse edge: A test cycle is started.
The output parameter TEST is set at “0”, i.e. the
ESPE/AOPD emitter is switched off.
For example, the enable or TDC
signal should be
connected to this parameter.
DANGER!
In “Guard only” mode (
GdO = 1), a test on the ESPE/AOPD
must only be carried out at a time when the guarding function
of the ESPE/AOPD will not be called upon.
• RSET: Reset button (N/O contact)
RSET = 0/1-pulse edge: Reset occurs
