When high alarm with Hold/Re-hold action is used for Event function,
alarm does not turn on while Hold action is in operation. Use in
combination with a high alarm without Hold action in order to prevent
overheating which may occur by failure of control devices, such as
welding of relays.
The hold action is effective when Process, Deviation, or Manipulated output
value action is selected for the Event type.
