DESCRIPTION

The DLM-812 is a microprocessor based dual mode monitor for the display and control of progressive in- line lubrication systems. Proximity switches mounted to the divider block system for Zone #1 and Zone #2 signals the DLM812 each cycle. The time between cycles is displayed on the LCD readout as time into the current cycle as well as the time for the previous cycle. Each 10 seconds the display changes to show the flow rate in pints/day, cycle time, total strokes, and system run time for both Zone #1 and Zone #2. If the time between cycles exceeds the programed alarm time an alarm signal is activated. The last I00 cycle times for the Zone #1 and Zone #2 lubrication systems are stored in permanent memory and can be read out via local control of program buttons.

(Note: Program instructions shown for Zone 1, instructions are the same for zone 2.)

PROGRAMMING FUNCTIONS

Press PRG. and hold PRG. use INC. or DEC. buttons to change functions. Pressing Exit button will return to normal operation.

1)Z1 BLK TOTL= Block Total - Programmable between 18-144. Use INC or DEC Button to set block Total for Zone #1.

3)Z1 ALR SEC= Alarm Time - Programmable between 3-250 seconds. Use INC or DEC Button to set block Total for Zone #1.
5)MEMORY Z1= Cycle Time Memory - Use INC or DEC Button to view last 100 cycle times for Zone #1.
NOTE: Memory is permanent, will not be lost in case of power failure.
7)RESET?_= System Reset - Press the INC or DEC Buttons at the same time to reset total strokes and hours.

DISPLAY: Automatically scrolls between Pints/Day, Cycle Time, Total Strokes, System Run Time.

Pressing (INC.) W ill lock display at the present function.

Pressing the (EXIT) will release the scroll lock and retur n to automatic.

Four(4) panel mounted buttons are used to change the setup parameters.

Program menu items are accessed by pressing the PRG button.

Pressing the PRG and either INC. or EXT at the same time will access the other menu items.

The INC. and EXT buttons will change a menu item slowly at first then rapidly if held down.

The exit button will return to the display mode if pressed at any time.
