Electronic Limits
You should set the electronic limits and assign a cross-
head action to them before starting a test. Enter limits
values using the keypad and view them on the Main
Panel Display.
An indicator lights at the active limit and at the corre-
sponding crosshead action key. A STATUS indicator is
lit whenever a limit is set to control a crosshead action.
The LED flashes after the limit is reached and the action
occurs, except at CYCLE and OFF.
Operating Notes - Limits Panel
(1) To enable either the load or strain channel limits, the
respective channel must be calibrated.
(2) When system operating units are changed, any Load,
Extension and Strain limits previously set on the Lim-
its Panel default to “0" and the related crosshead ac-
tion defaults to ”OFF". Any STATUS LED which is
lit to indicate an active load, extension or strain chan-
nel limit goes out. Each limit must be reset using val-
ues stated in terms of the new operating units, and
the crosshead action selected
(3) When the operating mode for the Strain channel is
changed (see page 5-18), any Strain limits previously
set on the Limits Panel default to “0" and the related
crosshead action defaults to ”OFF". The STATUS
LED, which may be lit to indicate that the limits for
the strain channel are active, goes out. Each limit
must be reset using values stated in terms of the new
operating mode, and the crosshead action selected.
