Additional flags on the display show the status of the two relay outputs, RL1 and RL2 ,and of the digital control inputs into the MSM400.

KEYPAD OPERATION :

There are 6 buttons on the MSM400 front panel, the four ARROWS allow navigation around the programming menu and the " ESC" and "ENT" buttons allow movement from one screen to the next. By pressing "ESC" repeatedly, the screen will always return to the normal display as shown in Fig 7. Movement through the menu structure using the arrows is shown by the titles being "highlighted", ie reversed to showing white letters on a black background. The LCD is backlit for operator convenience. (This can be turned off if required).
