Modular Block System: Hydraulic Presses 6-91
• SMd2: Sequential Mode 2
SMd2 = 0: For “Muting ON”, MS2 must be operated after
MS1 and then MS1 be released again.
SMd2 = 1: For “Muting ON”, MS2 must be operated after
MS1.
• THlp: Auxiliary timer
A flag word should be entered at this input parameter. The
flag word must be exclusively reserved for this block.
This means that this flag word, or any individual bit from this
flag word, must not be used elsewhere in the program, nor be
influenced from anywhere else within the program, even by
interrupt processing.
• RSET: Reset button (N/O contact) for error reset and start-up enable.
A key switch should be used for the reset button.
RSET = 0/1-pulse edge: reset occurs
INFORMATION
The SB monitors the maximum time values stated. If parameters are set
for a time value that exceeds the maximum permitted value, the SB will
automatically restrict the time by blanking out the higher-value figures. No
error message will appear in this case.
Please note:
This may mean that times are reduced to values which are considerably
lower than the permitted limits.
Wiring the input parameters
Type 4 ESPE/AOPD devices with semiconductor outputs can be
connected to DI 2 inputs (e.g. input module PSS(1) DI 2) in order to meet
the requirements of category 4.
Output parameters
• ENBL: Enable flag bit
ENBL = 0: Error detected (e.g. ESPE/AOPD interrupted)
ENBL = 1: The enable will occur if:
- the ESPE/AOPD is clear or muting is active and
- no error has been detected.
• MAct: Display muting status (for LED)
MAct = 0:
No muting (ESPE/AOPD active)
MAct = 1: Muting active (ESPE/AOPD suspended)
