Operation

The Raypak electronic temperature control uses a

Liquid Crystal Display (LCD) as a method of supply-

ing information. The LCD is used to setup and monitor

system operation by means of three push buttons

(Item, L and M) shown at the bottom of Fig. 33.

All items displayed by the control are organized into

two menus, the view menu and the adjust menu. The

active menu is displayed in the upper right hand side

of the display in the menu field. The default menu is

the view menu.

When the temperature control is powered up, the con-

trol turns on all segments in the display for 2 seconds,

then the software version is displayed for 2 seconds.

At the end of that 4 second period, the control enters

the normal operating mode and “VIEW” is displayed.

Pressing the scroll button “scrolls” through the dis-

played values in the “VIEW” menu.
