Command Reference: Function Blocks
Section 6-5
General Description
The Two-hand Control function block enables monitoring the status of a two-
hand switch.
The Two-hand Control function block can be used with a suitable 2-hand
switch to meet the requirements of type III C in EN 574,
Two-hand Control
Devices, Functional Aspect – Principle for Design.
The Output Enable signal will turn ON only if both inputs from the two-hand
switch are active and satisfy the requirements of EN 574. The Output Enable
signal will turn OFF if the inputs from the two-hand switch do not satisfy the
requirements of EN 574, an input is inactive, or if an error is detected for the
function block.
Set Parameters
The discrepancy times must be equal to or greater than the NE1A-series Con-
troller’s cycle time.
Optional Output Settings
The following error outputs can also be used in programming. To enable either
of these optional outputs, select the checkbox on the Out Point Tab Page of
the function block properties dialog box.
Discrepancy Error Pair 1
Discrepancy Error Pair 2
Fault Present Output Setting
Fault Present output can also be used in programming.
To enable this output, select the Use Fault Present checkbox on the Out Point
Tab Page of the function block properties dialog box.
