The high speed solenoid output is connected to a safety output on the PCSS and allows the
control of the high speed solenoid valves on the press brake. If the down enable condition
has been met but the down low speed condition has not been enabled, the high speed
solenoid output will be switched on and the pressing beam can move down at high speed.
This output will be switched off when down low speed is required.
The filler solenoid output is connected to a safety output on the PCSS and provided that:
•
High speed down movement has been enabled; or
•
The up command has been received from the CNC press controller after
decompression.
Both the decompression and holding solenoid valve outputs are enabled whenever the down
enable is set and are connected to safety outputs provided on the PCSS.
The safety solenoid valve output connected to a safety output on the PCSS and will be
enabled whenever the down enable is set or the up command has been received from the
CNC press controller after decompression.
The proportional enable output is used to enable the proportional solenoid valves on the
press brake and is connected to a standard output. This output remains on when the down
enable is on, the CNC press controller has initiated the up command after decompression or
during decompression.
Should the soft stop operation be enabled as described in
valves will be delayed in switching off until down movement comes to a complete stop. The
proportional enable output will switch off immediately and can be used to perform a controlled
decelerated stop.
