Display:
The display of the YHC is a 128 x 128 pixel graphic display with backlight. Viewable area is 2.6” x 2.6” for
13 viewable message lines.
KEY PAD:
The YHC keypad has three basic key types: single function keys, dual-function keys, and soft keys with changing definitions. Single function keys control a dedicated YHC function.
The YHC 4150X Intrinsically Safe unit must be powered by approved AA alkaline batteries (see the “Hazardous Area Use” section of this manual and the I.S. Control Drawing shipped with each YHC 4150X for more information). AA alkaline batteries are standard with the YHC shipment. For bench top applications and download operations, the AC adapter (P/N Z9B000007 included with each YHC) is recommended. The AC adapter is only for use in safe areas.
Located in the upper right corner of the display, this icon displays the remaining battery power. Fresh batteries produce a full black cell body. As the power drains, the black segment retreats indicating remaining power.
When the YHC is used with the optional AC adapter (P/N Z9B000007), the battery circuit is bypassed and a wall plug icon replaces the battery icon on the display header. For AC power use, the AC adapter is connected to the Communication / AC Adapter Dongle and then the dongle is connected to the fitting on the top of the YHC.
