CBMD12 12-Channel Bypass Module

Revision History

Introduction

Congratulations on your purchase of the Mirtron MPower CBMD12 12 Channel Bypass Module. Carling has designed and built your CBMD12 to the highest standards for years of dependable and accurate service.
The CBMD12 is designed to be installed in conjunction with the CLMD12 12-Channel DC Load Controller Module to provide a manual override method to control CLMD12 loads in the case of a CLMD12 malfunction or an NMEA 2000® network failure. The CBMD12 works by providing direct power to each CLMD12 load through physical switches for each load. The CBMD12 utilizes standard fuses for overcurrent protection.
The CBMD12 is designed to operate within the harsh demands of the marine environment.
However, no piece of marine electronic equipment can function properly unless installed and maintained in the correct manner. For best results, please read this user’s manual from start to finish to understand instructions for installation and usage of the CBMD12.
1.1 CBMD12 Features
The Mirtron CBMD12 has the following features.

• 75A max current capacity matches the max current capacity of the CLMD12 12-Channel Load Controller Module
• Included standard ATC fuses provide overcurrent protection to each circuit
• Max current markings on each fuse slot correspond with CLMD12 load outputs max current ratings eliminating the need for cross-referencing
• Label under ABS cover relates the CLMD12 breaker number to its corresponding CBMD12 bypass switch and provides a space to write in the load’s circuit name
• CLMD12 to CBMD12 main power jumper wire provided with CBMD12
• IP53 ingress protection with cover closed

Installation

2.1 Unpacking the Box
When unpacking the box containing the Mirtron CBMD12, you should find the following items:

• 1 – CBMD12 – 12 Channel Bypass Module
• 1 – 6 AWG Red Bypass Module Main Power Jumper Wire
• 1 – Bypass Module Fuse Pack
• 1 – Warranty Registration Card

If any of these items are missing or damaged, please contact Mirtron Technical Support.
Refer to section 8, (Technical Support), of this User’s Manual for contact information.
2.2 Loading CBMD12 Fuses
The CBMD12 contains a fuse pack with (Qty:4) 5A fuses, (Qty:7) 10A fuses and (Qty:3) 15A fuses. There are 12 slots for the fuses pertaining to the 12 CLMD12 load bypass channels and two slots for spare fuses. To have fuse protection that corresponds with the CLMD12 load output’s max current rating, simply insert the fuses into the fuse slots matching the fuse values with the noted ‘Fuse Max Rating Marks’ on the CBMD12 module. Refer to the figure below for additional detail.

Figure 1 – CBMD12 Fuse Max Rating Marks

2.3 Mounting the CBMD12
Mount the CBMD12 using (Qty:3) #8 pan head or other screws through the three provided mounting holes. Do not use thread locking compounds containing methacrylate ester, such as Loctite Red (271), as they will cause stress cracking of the plastic enclosure. The CBMD12 is designed to be mounted to the left side of any CLMD12 unit if the provided 6 AWG red bypass module main power jumper wire is used. It is also acceptable to use one CBMD12 for two adjacent CLMD12s or choose not to mount the CBMD12 and simply keep the unit as an onboard emergency use or troubleshooting device that can be connected at the time of need. See figure below for example illustrations of CBMD12 mounting configurations in conjunction with CLMD12 Load Controller Modules.

2.4 Connecting the CBMD12 (Main DC (+) Connection)
WARNING
The CBMD12 Bypass Module is not ignition protected. Ensure that the CBMD12 switches are in the off position and the installation area is free of fumes and gasses before connecting main power.
Typically, use of the provided 6 AWG red bypass module main power jumper wire will be used to power the CBMD12. When installing the CBMD12 in a standard mounting fashion as illustrated in Figure 2, the main power jumper wire will connect from the CLMD12 main DC (+) terminal stud located at the top of the CLMD12 to the CBMD12 terminal stud located at the bottom of the CBMD12. When installing the CBMD12 in an adjacent CLMD12 arrangement as shown in Figure 3, connect the provided main power jumper wire to the CLMD12 to the right side of the CBMD12. It is important that the ‘Right Side’ CLMD12 main DC (+) power cable has a current capacity that is equal to or greater than the current capacity of the CLMD12 to the left side of the CBMD12; therefore, the CBMD12 will have the capacity to carry bypass currents for either CLMD12 it will be servicing. If it is not possible to install the CBMD12 within reaching distance to use the provided main power jumper wire, then the CBMD12’s source of DC (+) can be provided by any cable with a ring terminal to the 1/4”-20 stud on the bottom of the CBMD12 as long as the power cable is protected by a fuse or circuit breaker with a value appropriate to protecting the wire or the 75A maximum specification of the CBMD12, whichever is less. Torque the DC (+) connection to the CBMD12 to 20 in-lbs. (2.26 N·m). Application of dielectric grease to the CBMD12 or CLMD12 DC (+) main power terminal stud is acceptable. See Figure below for illustration of connecting the provided CBMD12 main power jumper wire.

Operation

The bypass module provides a manual method (On/Off switch) to control CLMD12 loads by providing power to each load in case of CLMD12 malfunction and/or NMEA 2000 network failure. The power outputs provided by the bypass module are over current protected via an individual fuse for each output. Please ensure that the current rating of the fuse for each load is appropriate to protect the wiring for each load.
Please note that the bypass module does not support paralleled outputs, since each circuit is controlled by a separate switch. Additionally, the bypass module does not support dimming of circuits.
To change control from the CLMD12 load module to the CBMD12 bypass module, please perform the following steps:

1. Ensure that the area is free of fumes and gasses.
2. Ensure that all switches on the CBMD12 bypass module are in the OFF position.
3. Unplug the J1 connector from the CLMD12 load module.
4. Plug the J1 connector from the malfunctioned CLMD12 load module into the CBMD12 bypass module.
5. Switches on the CBMD12 are labeled in a seemingly random order. This is because the switch labels correspond respectively with the breaker numbers of the CLMD12 (1-12) rather than reading order of left to right, top to bottom.

For the circuits you wish to energize, turn the desired CLMD12 breaker number on by switching the on the respective switch number located on the CBMD12 bypass module.
Please refer to the figure below for a visual representation of a circuit in bypass mode.

Maintenance

Regular maintenance is important to ensure continued proper operation of the Maretron CBMD12. Perform the following tasks periodically:

• Clean the unit with a soft cloth. Do not use chemical cleaners as they may remove paint or markings or may corrode the CLMD12 enclosure or seals. Do not use any cleaners containing acetone, as they will deteriorate the plastic enclosure.
• Ensure that the unit is mounted securely and cannot be moved relative to the mounting surface. If the unit is loose, tighten the mounting screws.
• Check the security of the main DC (+) cables connected to the CBMD12 and CLMD12 tightening if necessary.

Troubleshooting

If you notice unexpected operation of the Maretron CBMD12, follow the troubleshooting procedures in this section to remedy simple problems. If these steps do not solve your problem, please contact Maretron Technical Support (refer to Section 8 for contact information).
