22.0   TROUBLESHOOTING THE DE-2200 MONITOR SYSTEM

22.1 The power LED’s on the Power Supply and Terminal Module are blank as well as the LCD

on the display module:
A.

Check the power supply voltage at the 12-24 Vdc input terminals; should be between
12 and 24 Vdc.

B.

Check the power supply power fuse and replace if blown.  NOTE: A spare fuse (part
number 601653 - 6.3 amp) is provided on the power supply board.  

C.

If the Terminal Module power LED or the Display Module LCD is not on, make sure the
25 pin connectors and cable assembly are connected and are secured.

22.2 The normally open sensors do not cause a fault:

A.

Make sure the power supply minus terminal is grounded to the panel and the panel is
grounded to the engine block.  They must all be at the same potential for normally open
sensors that use the engine block as a return path.  Use an ohmmeter and measure
between the power supply minus terminal and the panel and engine block - this reading
should be less than 2 ohms.

22.3 The output LED’s are changing state but the relays or solenoid valves connected to the

outputs are not tripping:
A.

Check that the wiring is correct and check the output module fuse.  NOTE: A spare fuse
(part number 601653 - 6.3 amp) is provided on the power supply board.  

22.4 The power LED’s are lit as well as the LCD backlighting but the LCD is blank or shows

“WARNING: THE DE-2200 Monitor MUST BE CONFIGURED PRIOR TO USE ON AN
ENGINE”:
A.

The monitor system needs to be configured.  See the programming instruction form DE-
2200 PI to configure the system.

22.5 The home screen displays NO COMM. message for either the speed, suction or discharge:

A.

Communications from the terminal PCB to the DE-2200 monitor have been broken.
Check cable connections.
