Modular Block System: Hydraulic Presses
Features:
• Synchronisation time of the gate switches is monitored
• The guard locking device is controlled
• Feasibility of the guard locking device is monitored
• Status display for safety gate and guard locking
Operating modes:
• Automatic start when PSS starts up or when starting I/O-Groups
(SafetyBUS p)/start-up reset when PSS is cold-started or when starting I/
O-Groups (SafetyBUS p) (start-up disabler)
• No function test/function test on the gate during start-up and each time

SB086: Overrun control on linear-driven presses
SB086 is designed to perform overrun control on linear-driven hydraulic
presses in accordance with VBG 7n5.2 §11.
Function
• Check performed via the overrun cam TLS (Test Limit Switch)
• Overrun measurement can only be started from the extreme top position
(ETP) of the press.
• Ability to set the overrun measuring period
• Overrun errors and hardware errors can only be reset when the press is
in the extreme top position
• Reset via 0/1 pulse edge at RSET input
• Can be used for overrun measurement on AKAS systems (Fiessler)
