We operate 2001 vintage 7EA units with Mark V control systems.
During some recent cold weather runs (8 deg F), most of our units had the following alarm:
<pre><b>LFSRCPR_ALM: COMP LIMIT FSR BACKUP CONTROL ACTIVE</b></pre>
While the LFSRCPR condition existed, the L70R (raise load) commands were prevented, therefore the unit did not load up to meet pre-select. This condition cleared on all but one of the units within a few minutes and they loaded normally from there. The other unit remained in that state for ~45 minutes, before it finally got past it and loaded up.
Have any of you all in the North experienced this alarm?
Do you have insights and advice to offer?
