Indicator Light (Red -
):
When the Pause and Rimless buttons are engaged, this indicator lights to show
that the edger is in the Flow Control mode. (See Flow Control Knob.)
Stop/Reset (Red -
):
Pressing this button at anytime will abort the cycle and return the lens
drive/cutter motor carriages to their start position.
Pause (Yellow -
):
The Pause control can be used in two modes:
1. When engaged during the first half of the cutting cycle (roughing), it
will
freeze
the cycle. It will complete the roughing cycle but prevent
the edger from advancing to the finishing cycle until it is released. The
lens spindle and cutter motor will continue to rotate.
2. When engaged during the second half of the cutting cycle
(finishing), the lens spindle and cutter motor will continue to rotate,
but the cycle will not advance until the Pause button is released.
The Pause button is also a visual indicator as to whether the edger is in the
roughing or finishing cycle, as the switch light flashes during the finishing
half of the cycle.
The Pause feature is particularly helpful when executing mid-cycle
adjustments to the bevel (or groove) placement.
For example,
if an operator
wished to check groove placement on a thin-edged, high plus lens prior to
final sizing, he or she could set the sizing dial 2mm oversize and stop the
cycle during the finishing (grooving) operation. After fine adjustments, the
cycle could be resumed by turning down the sizing dial to the correct size, and
releasing the Pause button.
Start (Green -
):
This switch begins the edging cycle.
