Standard Symbols The following defines standard symbols used in this publication. Scope Notes inform the reader about information that is required, but not ATTENTION immediately evident. Cautions tell the user that damage may occur to equipment if CAUTION proper care is not exercised. Warnings tell the reader that potential personal harm or serious WARNING economic loss may happen if instructions are not followed.
INTRODUCTION Section 1 1.1 OVERVIEW This publication provides detailed instructions for maintenance, test, troubleshooting and repair of the Dual Node Module (part of the TDC 3000 X system) shown in Figure 1-1. The troubleshooting, disassembly, and assembly procedures are effective down to the optimum replaceable-unit (ORU) level.
MODULE DESCRIPTION Section 2 2.1 GENERAL DESCRIPTION The Dual Node Module is a chassis containing one or two nodes. Each node performs an independent function and occupies a specific address on the Local Control Network (LCN). Figure 2-1 shows the module functions within a typical TDC 3000 X System. The types of nodes available in the Dual Node Module include Application Modules, Network Interface Modules, History Modules, Universal Stations, Hiway Gateways, and other types of gateways.
SlCLCNA and CLCNB boards. Do not plug any other type of board into these slots unless specifically authorized by Honeywell documentation, or damage may result. This is particularly true for CSR boards—DO NOT plug a CSR board in I/O Slot 1.

2.4 FRONT PANEL The module front panel has the necessary windows and switch openings to accommodate two nodes in a single module. Figure 2-3 shows the front panel for the Dual Node Module. For each of the two power supplies, there are openings for the POWER switch and RESET switch and a window to view the light-emitting diode (LED) status indicators.
2.5 REAR PANEL ASSEMBLY The Rear Panel Assembly includes the Backpanel Printed Wire Assembly (PWA) and the Input/Output (I/O) Card Cage Assembly. The power supplies, the fan assembly and the main circuit boards (such as the K2LCN OR K4LCN) all plug into card edge connectors on the front side of the Backpanel PWA.
2.7 FIELD ADJUSTMENTS There are no field adjustments for the Dual Node Module. However, the K2LCN must be pinned for the particular node address it occupies on the LCN. Figure 2-4 shows the pinning options for the K2LCN. The EPDGC-(I/O) board, if present, has pinning options to set the default background shade for the CRT if a palette has not been set in a schematic (Set Palette is a new command in Release 320).
LCN Address Jumper Out = 1 This Sample is 43: NOT ON BOARD Pinning Jumper In = 0 PARITY The overall number of jumpers out, including the parity jumper, must be an odd number. Note that addresses 0-127 BINARY could be set, but software WEIGHT will allow only node addresses 1-64.

2.9 PRECISION CLOCK PINNING (POWER SUPPLY REPLACEMENT) The power supply has a pinning option for internal or external clock (see Figure 2-11). It is pinned for internal clock unless the Precision Clock Source option is installed. If you are replacing the power supply, check the pinning on the old supply and ensure that the replacement is pinned the same.
The CE Compliant power supplies come from two vendors. The external clock source pinning is shown in Figures 2-12 and 2-13.

2.10 2.10 NIM MODEM BOARD PINNING Location SW1 has the revision pinning for the NIM Modem board. This pinning reflects the revision of the board and is never to be changed unless the board is updated. Location SW2 has the pinning for the UCN node address. This address is a binary weighted number and is used only in the Test mode.

2.11 2.11 POWER SUPPLY LOADING IN LCNE/LCNE2 HOST NODE The LCN may be extended with one or more Fiber Optic Links. An otherwise empty node of a Dual Node Module may be used to host the LCNE/LCNE2 fiber optic transmit/receive boards.
TEST/TROUBLESHOOTING Section 3 3.1 TESTS Each node of the Dual Node Module is tested through firmware (in hardware) and software checks. Firmware tests built into the node provide two similar means of functionally checking the unit, whether or not it is connected to the LCN. The first firmware test starts when power is applied.

DISASSEMBLY/ASSEMBLY Section 4 4.1 DISASSEMBLY W A R N I N G To protect equipment from voltage transients and ensure reliable operation, always turn power off before removing or replacing boards in a node. While working on one node in a Dual Node Module, you may leave the power on for the other node, leaving it operational.
Figure 4-1 — Module Exploded View 4122 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 any pins or switch settings (e.g., the node address on the K2LCN OR K4LCN board) match those on the board being replaced.
SPARE PARTS Section 5 5.1 INTRODUCTION Table 5-1 lists spare parts for the 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 circled numbers in Figure 4-1. Also listed are those boards required for the various Dual Node Module configurations, referenced in Tables 2-2 and 2-3.

STARTUP Section 6 6.1 VISUAL CHECKS • Check the Module power and signal cables to ensure that they are present and tight. • Check the ground strap on rear of chassis for good connection. • Ensure that all boards and power supply(s) are fully inserted into the connectors and that board retainers are secured.
ALPHANUMERIC DISPLAYS Appendix A The alphanumeric display aids troubleshooting by displaying codes provided by firmware and software test programs. In interpreting the codes, pay special attention to the left-most element. As shown in Figure A-1, this element can have four distinct states, and reading the display correctly is critical to interpreting the code.
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.

REPLACEMENT OF K2LCN WITH K4LCN Appendix B This appendix gives the procedure for replacing an K2LCN processor with a K4LCN. It also gives the restrictions and conditions that apply to the replacement procedure. B.1 INTRODUCTION This procedure enables a trained technician to replace an K2LCN processor board with a high density 68040-based K4LCN processor board in a Five-Slot or Ten-Slot Module LCN node.
B.2 RESTRICTIONS TO TOTAL REPLACEMENT If you are contemplating the replacement of all K4LCN processors in Five/Ten-Slot Modules, be aware that the Clock Source/Repeater board is the single point ground connection for the LCN cable shield. Therefore, even if the 12.5 kHz (Subchannel) clock function is not being used, a CS/R or other grounding means is still required on each coax segment.
B.6 REDUNDANT MODULE REPLACEMENTS 1. This section applies only to a redundant Network Interface Module (NIM), Hiway Gateway (HG), or Programmable Logic Controller Gateway (PLCG). 2. Determine in which unit, the primary or secondary, you want to perform the replacement first. The recommended procedure would have you replace the processor in the primary unit first.
B.8 REASSEMBLY 1. Check that the LCN I/O card you have is revision T (or later). Set the correct node address into the LCN I/O card and install it in Slot 1 in the rear of the module (or the LCNFL, if one was removed in step 6 above.
