Modular Block System: Hydraulic Presses 6-19
INFORMATION
The two-hand device/console is correctly disconnected and deselected
when:
Input parameter T1.2 and T1.4 = 0
T2.2 and T2.4 = 0
Output parameter FG, GST, AUF = 0
OFF = 1
In all cases, an error message will be issued when a two-hand device/
console is disconnected. You will need to take one of the following actions:
• The two-hand device/console is disconnected, but still selected via the
key switch:
Deselect the console via the key switch and then reset.
The two-hand device/console is now correctly deselected and
disconnected (please refer to “Error messages” under “Bit 04”).
• The two-hand device/console is deselected via the key switch, but is still
connected:
Disconnect the console and then reset.
The two-hand device/console is now correctly deselected and
disconnected (please refer to “Error messages” under “Bit 05”).
A dummy connector is not required to act as a buffer when unplugging
a two-hand device/console.
DANGER!
If a two-hand circuit is deselected using the input parameter Off, a diffe-
rent safety device must be employed in its place.
Remember that the two-hand circuit has a safety function in addition
to its operator function.
