Where can RM-11 be read from?

A

MCR

HP

TSC

Computer Room

  • HP, TSC, and Computer room can only use “User Mode.” (Data Retrieval/acknowldeging alarms)
  • MCR normally uses “Windows Supervisor Mode.” (Allows non-tech spec parameters to be monitored)
  • “RM-11 Supervisor Mode” can only be used in MCR and requires password. (Allows changing of setpoints)
