Edwards 4X-LCD-LC — EST3X main user interface assembly with a monochrome quarter-VGA LCD, four controls and the SpeedTouch rotary knob, shipped with English language inserts.
This is the display and control face of an EST3X panel, not a panel and not a remote annunciator. It hangs on hinge pins on the SFS1-CPU main board and connects with a single ribbon cable, so a cabinet, CPU and power supply must be in place already.
- Backlit monochrome LCD, 240 × 320 pixels, 24 lines of 40 characters
- Shows up to eight concurrent messages
- Four dedicated control buttons plus the SpeedTouch rotary control
- Operating current 55 mA standby, 66 mA alarm
- 32 to 120 °F, 0 to 93 percent relative humidity, non-condensing
The separator from the plain 4X-LCD is language, not hardware: Edwards catalogues 4X-LCD as English language and 4X-LCD-LC as insertable language shipped with English inserts, alternate languages ordered separately. No Edwards document read defines LC. A display of this type is included in the EST3X basic package, so one ordered separately is a spare or an extra point of control on the network.
