5 Shutdown Symptoms

Clearing an MS Shutdown

Unlike other shutdowns, you cannot clear this state by turning

off a setpoint (because setpoint changes are blocked). Instead,

clear this state by disabling GC to MS communications.

5977A, 7000C, 7010:

1 Press [MS/Aux Det].

2 Scroll to MS Communication.

3 Press Off/No.

5977B:

1 Press [Config][MS/Aux Det].

2 Scroll to Lvds communication.

3 Press Off/No.

If the GC started the shutdown, you can now troubleshoot the

problem and resolve the GC fault.

After resolving an MS Shutdown

After resolving the GC or MS problem, always restore GC to MS

communications.
