4.12.4 Set MIV–A Module Address (Master) (Slave)
When the SAM system includes more than three Hale MIVs, two MIV–A modules are required.
When two MIV–A modules are present, the left most MIV–A module must be addressed to be a
master and the right most MIV–A module must be addressed to be a slave.
NOTES
If replacing a MIV–A order a master if replacing a master or a slave if replacing a slave.
If the CAN bus is stable (normal PWR, BUS, and COM indications) and the MIVs do NOT
function then typically there is an address issue.
The module does NOT have to be removed if access permits setting the address with
the module in place.
Prior to setting the address, perform the Removal portion of the R&R procedure.
See paragraph 4.8.3 (page 93) and NOTES above.
To verify or set the address of a MIV–A module, perform the following.
A.
Place module on flat stable work surface. (See NOTES above.)
TO PREVENT PCB DAMAGE, DO NOT REMOVE THE COVER OR CHANGE THE CAN AD-
DRESS WITH THE MODULE POWERED ON.
B. Remove PCB from protective case as follows.
LIFT TABS ONLY ENOUGH TO RELEASE THE PCB. LIFTING THE TABS TOO FAR CAUSES
THEM TO BREAK. IF A TAB BREAKS THE MODULE IS NOT PROTECTED FROM THE ELE-
MENTS AND MUST BE REPLACED.
Using a 1/4-in straight blade screwdriver, lift tab on one side of protective case.
Pull connectors away from case to keep tab lifted.
Using screwdriver, lift tab on other side of protective case.
Pull connectors away from case to remove PCB.
If PCB does not slide out of case, repeat Step 1 thru Step 4 using two people.
(One person spreads the tabs while the other pulls the PCB out of the case by the con-
nectors.)
