An attempt was made to actuation the T2 profile monitor, however it showed up in EPICS as being not present. Furthermore, the "Remote" indicator light on the physical controller was not lit up despite the switch being in remote mode. The limit switch indicator light was working.

Upon troubleshooting with Erwin Klassen, it was determined that a jumper was missing on the profile monitor control connector (on the target end, rear of bulkhead). The jumper shorts pins A and G on the mil-spec connector on the controller end, which is for 120 VAC supply, to indicate that the device is connected. T1-MK1 was checked - this jumper was present on T1-MK1, across pins E and F of the mil-spec connector, but was not present on T2-MK1. Otherwise the connectors were identical. It is suspected that it was accidentally omitted during maintenance in the past. Regardless, a new jumper was soldered in-place on T2-MK1 across pins E and F to replicate T1-MK1. The system functioned normally after this.

Attached photo shows the completed solder job - the current state of the connector on the rear side of the target bulkhead panel.
