This is the value used to limit the output power ofthe loop and is derived from the gain scheduled limit, the remote limit and the safetylimit.The high limit for the working output. This is the value used to limit the output powerof the loop and is derived from the gain scheduled limit, the remote limit and the safetylimit.Loop Break Alarm. Becomes active ‘Yes’ if the loop break time (LBT), set in the PIDmenu (Section 4.6.4) is exceeded, otherwise ‘No’ is displayed.Shows the proportional term contribution to the control outputShows the integral term contribution to the control outputShows the derivative term contribution to the control outputIndicates sensor break status. On (tick symbol) indicates a sensor break has occurred;Off (cross symbol) shows that no sensor breaks have been detected.The scheduled proportional band for the current PID set.The scheduled integral time for the current PID set.The scheduled derivative time for the current PID set.The scheduled relative cool gain value for the current PID set.The scheduled cutback high value for the current PID set.The scheduled cutback low value for the current PID set.The scheduled manual reset value for the current PID set.The scheduled loop break time for the current PID set.The scheduled output low limit for the current PID set.The scheduled output high limit for the current PID set.HA030554Issue 7 Nov 12Page 105
