10.5. Examples of Failures and Their Counter-Operations
Procedures for acknowledging and resetting failures are explained here.
10.5.1. Failure example 1: Communications failure
Assuming that the RM-300MF’s connection is disconnected within the VM-3000 system, when the failure is
detected, the equipment operates as follows:
[Operation examples when a failure occurs]
Note
The RM-300MF cannot be used.
Step 1. Press the VM-3360VA or VM-3240VA’s [OK] key (to acknowledge the failure).
The buzzer stops and the yellow Failure indicator light switches from flashing to steady on mode.
Step 2. Determine the cause and remedy it.
Then correctly reconnect the cables between the RM-300MF and the VM-3360VA or VM-3240VA.
Step 3. If communications are restored, the system automatically returns to the previous status, causing the
VM-3360VA or VM-3240VA’s Failure indicator and the RM-300MF’s Communications Failure indicator
to go out.
