Is there a way to cancel an NCR?  This one was created in error.
Thanks,

PART DESCRIPTION: 	C100 Cryomodule
TRAV_ID: 	C100R-CMTF-CM-ACTS
TRAV_REV: 	R4

DESCRIBE STAFF: 	MICHAELM
DESCRIBE DATE: 	05-Apr-2023 09:13
DESCRIBE COMMENT: 	IR detector behavior is in reverse to what it 
normally is for a C100. Normally voltage rises with increasing field due 
to heating. If the voltage is above the trip point things should fault. 
In this case the interlock only engages when the trip point setting is 
below the read voltage. (ie - system expects CWWT voltage to drop with 
increased heating.) LLRF is aware of it and planning a hardware fix - 
for this test we will simply monitor voltages ourselves.
