4.4 Two-hand operation/jog mode
The two-hand operation function in accordance with type IIIC can be set in program 4 of
the UE410-MU/UE410-XU:
• Two pairs of complementary inputs (N/O / N/C contact pairs of both two-hand buttons)
are monitored.
• A valid input signal is only generated if the ON state (H/L level) exists at both inputs
within a period of 0.5 s (synchronous change, both two-hand buttons pressed) and if
both were in the OFF state (L/H level) beforehand.
In Program 5 at the main module UE410-MU the logic path B can monitor normal two-hand
operation (synchronous pressing of two pushbuttons within 0.5 s program 5.1), or two-
hand operation in jog mode (program 5.2), for example for traversing movements. Two-
hand operation in jog mode allows feeding or setting-up procedures.
The two-hand operation function in accordance with type IIIA can be set in program 5.1 of
the UE410-MU/UE410-XU:
• Two equivalent inputs (N/O contacts of both two-hand buttons) are monitored.
• A valid input signal is only generated if the ON state (H level) exists at both inputs within
a period of 0.5 s (synchronous change, both two-hand buttons pressed) and if both
were in the OFF state (L level) beforehand.
The jog operation function can be set in program 5.2 of the UE410-MU/XU:
• The evaluation in jog mode corresponds to two-hand operation IIIA with the difference
that the ON signal is limited to a duration of 5 s.
In the case of two-hand operation in jog mode an output signal is only generated as long
as both actuating parts are pressed. In jog mode, the duration for which the safety outputs
Q3/Q4 are on is limited to 5 s.
When the two actuating parts are released, the time is reset. Renewed activation of the
two actuation parts is possible.
In order to activate jog mode, terminal S2 remains unused. For two-hand applications,
S2 is jumpered with the supply voltage +U
B
.
It is not impossible to implement two-hand applications using a UE410-GU.
