D8C AuditLok XLV Electronics & Electrical System

Kit Vs. Board Level Service

In some cases it is more cost/time effective to replace the electronics can, main vend board and outer door lock board as a complete kit regardless of which board is suspected of failure. Installing a complete electronics kit will prevent having to perform the fairly tedious and time consuming task of performing a Device Search (Section 7) to get all boards in the D8C to communicate. This is because kit components have already been configured by the factory to work together. Introducing a new CPU, lock board or vend board will usually require you to perform a Device Search in order to establish internal communication. The can in the D8C Kit can does not include the inner door lock board. The D8CI Kit does include the inner door lock board. Refer to the Electrical Parts list for a complete list of part numbers.

Can

The electronics can inside the D8C contains the CPU assembly, the Lock Board for the inner door (if applicable), the internal power harness, and various other interconnecting cables.

D8C/D8CI Can Wiring Diagram

Can Removal

Perform all of the following steps that are applicable and possible. The following procedure assumes the CPU assembly is being replaced, whether individually or as part of a complete can replacement. If the CPU has failed steps 1 through 5 will not be possible.
1. Print a Config Report.
2. Print an Enrolled User Report.
3. Print an End Day Report.
4. If the system includes one or more R-units: Perform the Remove Device procedure (Section 7) to remove all V1R and V2R-units.
5. If the system has more than one display: Perform the Remove Display procedure (Section 7) to remove Display 01 and above.
6. Open the doors.
7. Disconnect cables to the can at the rear panel of the safe.
8. Disconnect cables to the can inside the safe.
9. Remove the 11/32 hex nuts holding the can in place.
10. Carefully pull the can out of the safe.

Can Installation

If the can is replaced without also replacing the Vend and Outer Door Lock boards refer to CPU Replacement procedures (below) before installing the can.
1. Place the can in position over the mounting studs inside safe.
2. Reinstall the mounting nuts.
3. Reconnect internal cables to the can.
4. Reconnect the printer to the rear of the safe.
5. If applicable: Reconnect the Lantronix or external modem to the rear of the safe. Reconnect the alarm cable.
6. If the main display for the safe is mounted in an EPR rather than the front of the safe: reconnect the data bus to the EPR only. Do not reconnect the data bus to any V1R, V2R or EPR displays at this time.
7. Reconnect the main safe power supply. An audible door alarm may sound when the safe powers up. If so, ignore it. DO NOT CLOSE ANY SAFE DOOR UNTIL DOOR OPERATION IS VERIFIED.
8. Verify door operation before closing doors.

CPU Replacement

The CPU is the brain of any Autobank system. When the system includes a D8C, the D8C is the unit with CPU. One CPU can manage up to 15 R-units attached to it. The CPU assembly is comprised of the CPU top and bottom boards. These two boards always come as an assembly. Do not attempt to separate them or swap individual parts. The assembly is always mounted inside the electronics can.
1. Perform the Can Removal procedure (see above).
2. Remove the four small Phillips head screws from the can cover plate.
3. Remove the cover plate and set aside.
4. The CPU is a two-board assembly mounted toward the top (closest to the back panel connector plate). The inner door lock board (if present) is mounted below the CPU.
5. Use a permanent marker to mark each cable connected to the top row of ports on the CPU assembly, then disconnect each of these.
6. Use a permanent marker to mark each cable connected to the bottom row of ports on the CPU assembly, then disconnect each of these.
7. Disconnect the power harness from the other side of the CPU assembly.
8. Remove the mounting screws from the CPU assembly and Remove old CPU.
9. Install the new CPU assembly and replace the mounting screws.
10. Reconnect the power harness and all RJ45 connections to the CPU.
11. Connect Vend Power, Vend Data, and Display cables to the can (this will require setting the can inside the safe, but do not mount it at this time).
12. Connect safe power to the can.
13. Check device inventory and if necessary perform a Device Search (see Section 8).
14. Disconnect Safe Power, Vend Power, Vend Data, and Display cables.
15. Reinstall the can cover plate.
16. Perform the Can Installation procedure (see above).
17. Perform System Restoration (see below).
18. Default new CPU login IS User 0 and PIN 1536.

Inner Door Lock Board Replacement

1. Perform the Can Removal procedure (see above).
2. Remove the four small Phillips head screws from the can cover plate.
3. Remove the cover plate and set aside.
4. Disconnect all cables from the lock board.
5. Remove the lock board mounting screws.
6. Replace the lock board.
7. Reinstall the lock board mounting screws.
8. Reconnect cables to the lock board.
9. Connect Vend Power, Vend Data, and Display cables to the can (this will require setting the can inside the safe, but do not mount it at this time).
10. Connect safe power to the can.
11. Check device inventory and if necessary perform a Device Search.
12. Disconnect Safe Power, Vend Power, Vend Data, and Display cables.
13. Reinstall the can cover plate.
14. Perform the Can Installation procedure (see above).
15. Perform System Restoration (see above).

Outer Door Lock Board

Refer to D8 Outer Door Locking System Instructions.

System Restoration

This procedure assumes the CPU assembly and/or inner door lock board was replaced, whether individually or as part of a complete can replacement.
1. If the system includes R-units and/or additional displays: Perform the Add Device procedure (Section 7) to add the R-units (including extra displays) back to the system.
2. Print a Config Report.
3. Mark the Config Report with all of the differences from the pre-repair Config Report. This will allow you to see what settings must be reprogrammed.
4. Reprogram device settings as required. In particular all board names will need to be entered. If the safe has two doors it may be necessary to try opening each door listed to verify which door is which. Note that the D8C Inner Door must be set Behind the D8C Outer Door and the D8C Outer Door must be set behind None.
5. Create box cash for each manual and validated drop compartment.
6. Create macro cash made up of all validated drop box cashes if and only if the system includes more than one validating safe.
7. Print another Config Report and a Cash Report. Verify them against the originals and make any additional changes required.
