D12LS-VM control-indicating modules troubleshooting
The D12LS-VM control-indicating modules operate independently of the option card on which they are installed.
However, they use the option card’s electronics to communicate with the VM-CPU.
The lamp test function will quickly isolate hardware problems from programming problems with any control-
indicating module. See “Performing a lamp test” on page 46.
