a. This is a specific starter test where the Shorting
Contactor (1K3) is individually energized and a check is
made to ensure that there are no currents detected by the
CT's. If current is detected when only S is energized at
Start, then 1M is shorted. b. This test in a. above applies to
all forms of starters (Note: It is understood that many
starters do not connect to the Shorting Contactor.).

Starter Type]
As part of the normal start sequence to apply power to the
compressor, the Shorting Contactor (1K3) and then the
Main Contactor (1K1) were energized. 1.6 seconds later
there were no currents detected by the CT's for the last 1.2
Seconds on all three phases. The test above applies to all
forms of starters except Adaptive Frequency Drives.

Immediate NonLatch All
Communication has been lost between the UC800 and the
applicable AFD. Once triggered, this diagnostic will auto-
reset after 10 continuous minutes of restored
communication to the compressor. (Note: The timer only
starts once communication to the compressor is restored,
which the UC800 will detect. If a manual reset request
occurs during the timer period, it shall reset the diagnostic
and the ‘auto-reset’ function will then be bypassed.)

Running
The AFD failed to start within the allotted time (1 min).
Definition of the “starting” value is the running status of the
AFD. Note: This is a Controller diagnostic, not one
originating from the AFD.
