Installation Guide for Industrial Electronic Engine Displays Caterpillar

Installation

The Analog Power Display requires an ECM that is capable of broadcasting information over the J1939 data link.

The J1939 data link is utilized to send engine operating information to the control module for the Analog Power Display. The control module supplies a signal in order to display operating information on an analog gauge. Two LED indicators on each gauge can alert the operator of problems with the engine and/or data link communications. A liquid crystal display on the tachometer gauge can display hours and diagnostic codes. Refer to the section on Troubleshooting, "Analog Power Display - Test" for more information. A maximum of 12 gauges may be connected to the control module for the Analog Power Display. Refer to Table 1 for a list of available gauges.

Mounting the Analog Power Display

Dimensions

Illustration 1	g00887155
Mounting dimensions for the control module in millimeters

Mount the control module in a location that is protected from direct exposure to moisture. Also mount the control module away from vibration. If the control module must be exposed to vibration, use rubber grommets to absorb the vibration. The control module may be mounted alone or the control module may be mounted to the back of a 3 inch gauge.

1. Mounting the control module alone

   1. Determine the location for the mounting of the control module. Allow extra space for the routing of the harnesses.

   2. Drill two holes in the mounting surface at the specified spacing. Hole size will be determined by the type of fastener that is used to mount the control module. Refer to Illustration 1 for proper spacing of the holes.

      Note: The holes for the fasteners are 4.5 mm (0.18 inch) in diameter.

   3. Mount the control module with the appropriate fasteners.

2. Mounting the control module to a 3 inch gauge

   1. Attach the control module to the back of the 3 inch gauge. The control module will be held in place by the studs on the back of the 3 inch gauge. Align the notch in the control module with the connector on the 3 inch gauge.

   2. Use two nuts to fasten the control module to the 3 inch gauge.

2. Determine the location of each gauge on the panel. Mark the location for each gauge on the panel.

   Note: The thickness of the panel must be between 3.18 mm (0.125 inch) and 12.7 mm (0.50 inch).

3. Cut out the hole and the keyway for each gauge. Refer to Illustrations 2 and 3 for the proper hole size.

4. Remove the mounting nut from the back of the analog gauge.

5. Place the seal on the mounting surface.

6. Place the gauge in the proper cutout in the panel. Align the key on the gauge with the keyway in the cutout.

7. Screw the mounting nut to the back of the gauge or attach the mounting bracket to the studs on the back of the gauge.

Connecting the Analog Gauges

Connecting the Analog Gauges to the J1939 Data Link

Illustration 4	g00888969
Schematic for analog gauge connection to the J1939 Data Link

1. Turn the keyswitch to the OFF position.

2. Connect the 3-pin connector of the 165-0200 Cable to a 133-0970 Receptacle As (Tee).

   Note: Refer to the topic in "Wiring (J1939 Data Link)" for more information on installing the J1939 data link.

3. Connect the remaining end of the 165-0200 Cable to the J44/P44 Engine connector for the 210-4309 Control Module. Refer to Illustration 4.

   Note: The total length between the 133-0970 Receptacle As (Tee) and the control module should not exceed 1 m (3.3 ft).

   1. Connect the yellow wire (J1939 +) to P44:2 of the control module.

   2. Connect the green wire (J1939 -) to P44:3 of the control module.

   3. Connect the bare wire (J1939 shield) to P44:4 of the control module.

4. Connect P44:1 (Switched +Battery) to a switched +Battery source.

5. Connect P44:6 (-Battery) to the negative battery bus bar.

6. Connect a switch for backlighting. Refer to Table 3.

   Note: The switch for backlighting is optional.

   An optional switch may be installed in order to control the backlighting. The momentary switch allows the operator to adjust the backlighting intensity. Cycling the switch will increase the backlighting intensity by one level. There are 10 levels of backlighting intensity. The default intensity is level 5. Once the maximum intensity is reached, the intensity will return to level 1.
