INTRODUCTION Section 1 1.1 OVERVIEW This manual provides detailed instructions for maintenance, test, troubleshooting, and repair of the Multinode Module shown in Figure 1-1 (with front cover installed) and Figure 1-2. The Multinode Module will not have the front cover installed when mounting in Micro TDC 3000 or LCN cabinets.
This manual also contains information about the EC compatible Ten-Slot Module. It accommodates both the older and newer EC I/O board designs. The EC card file remains the same in all other details except each I/O board has a faceplate which provides grounding of the board and cable shield to the card file.
MODULE DESCRIPTION Section 2 2.1 GENERAL DESCRIPTION The Multinode Module is designed to mount either horizontally in a standard NEMA rack or vertically in a cabinet (or tower) designed to stand vertically on the floor. Cooling is provided by four fans in one side of the module enclosure. An integral power supply is located at the bottom (or side) of the module.
2.2 MODULE AND NODE CONFIGURATIONS Circuit board slots are numbered from 1 to 10 starting at the bottom (nearest the power supply). When the module is oriented vertically, the slots are numbered from right to left. Nodes within a single Multinode Module are in a 3/3/2/2 arrangement, with slots 1 through 3 containing the first node, 4 through 6 containing the second node, slots 7 and 8 containing the third node, and slots 9 and 10 containing the fourth node.
2.2.1 2.2.1 Multinode Module Node Configurations Because of the limited board space, the boards used to construct various nodes must contain only certain boards and be configured as shown in Table 2-1. CAUTION Power must be removed from the module whenever you are removing or installing any board, including an I/O paddleboard.

2.2.1 CAUTION Power must be removed from the module whenever you are removing or installing any board, including an I/O paddleboard. Be sure that an I/O paddleboard is installed in the correct slot; some boards have only one slot that they can be installed in without causing damage. I/O paddleboards plugged into the wrong slot can cause traces on the backplane to burn open.
2.2.2 2.2.2 Multinode Module Node Configurations (CE Compliant) Because of the limited board space, the boards used to construct various nodes must contain only certain boards and be configured as shown in Table 2-1. CAUTION Power must be removed from the module whenever you are removing or installing any board, including an I/O paddleboard.

I/O paddleboards plugged into the wrong slot can cause traces on the backplane to burn open.
2.2.3 2.2.3 Multinode Module Board Types The board types listed in Table 2-3 are the current production board types suitable for use in the Multinode Module.

2.3 FRONT PANEL Controls on the front panel of the power supply consist of a switch, a POWER RESET button, a and a margin jumper. The function and operation of FAN CONTROL, LO-NOM-HI the power and reset controls are discussed elsewhere in this manual. The margin jumper is a power supply test/maintenance diagnostic aide and should be left in the (center) jumper position at all times.
2.5 FIELD ADJUSTMENT There are no field adjustments for the Multinode Module. Each K2LCN board, however, has a node address jumper-pack that must be characterized for the particular node address it occupies on the TPLCN. Refer to subsection 8.1 of the LCN System Installation manual for system pinning.
TEST/TROUBLESHOOTING Section 3 3.1 TESTS Testing of the Multinode Module is accomplished through both hardware/firmware tests and software. Hardware/firmware tests are built into the module to provide two means of functionally checking the unit, whether or not it is connected to the LCN. The first test is initiated when power is applied.

If the fault cannot be corrected by performing these procedures, refer to Appendix A for further information on the alphanumeric display. If the fault still cannot be isolated, contact the Honeywell Technical Assistance Center (TAC). CAUTION All assemblies used in this module are likely to contain electrostatically sensitive devices.

3.3.2 3.3.2 PWB Troubleshooting The K2LCN processor boards used in the Multinode Module have indicators on the front of the board to indicate error conditions. These processor boards have a red LED bar display with no labels as shown in Figure 3-3. In the sections to follow, use these indicators in conjunction with indicators on the input- output and controller boards to find the faulty PWB.

DISASSEMBLY/ASSEMBLY Section 4 4.1 DISASSEMBLY The Module should be disassembled only to the extent necessary to service or replace defective parts. The following procedures require the use of a blade-tip or Phillips (if EC hardware) screwdriver, personnel grounding strap, and antistatic fixtures and equipment. Item numbers called out in the procedures refer to ballooned numbers in the exploded Multinode Module diagram, Figure 4-1, and are keyed to the item numbers in Spare Parts, Section 5.
NOTE Before inserting a replacement board: 1. Make certain that the replacement board is at a revision level equal to or later than the board being replaced. 2. Make certain that the pinning of the node address on a K2LCN board matches that on the board being replaced.
SPARE PARTS Section 5 5.1 INTRODUCTION Table 5-1 lists spare parts for the Multinode Module. Those parts at the ORU level are marked with an asterisk (*). The listing is arranged in item-number order with the items keyed to the call-out balloons in Figure 4-1. Also listed are those boards suitable for use in the Multinode Module configurations.

STARTUP Section 6 6.1 VISUAL CHECKS • Check Module power and signal cables to ensure that they are present and tight. • Check ground strap and/or leads on rear of chassis for good connection. • Ensure that all boards and power supply are fully inserted into the connectors and that board retainers are secured.
ALPHANUMERIC DISPLAYS Appendix A The alphanumeric display enhances the man-machine interface by displaying hardware/ firmware and software-driven messages. In interpreting the messages, special attention should be paid to the left-most element. As shown in Figure A-1, this element can have four distinct states and the correct reading of the display is critical to understanding the message.
Please note, when multiple recommendations are given for a window code-value, they are organized in order from most to least likely. Recommendations marked with * indicate an unimplemented code-value. Any such occurrence should be brought to the attention of Honeywell TAC. Window values marked as are "don't care" values.
