4.4.1 PROGRAM EXECUTION
To achieve Program Operate Mode, from any meter display press the PROGRAM key. This will cause
the PROGRAM display to become active. The last or currently executing program will be displayed.
You may enter a new program number then press ENTER to view it.
PROGRAM: #1 FORM=3 COUPLING=DIRECT
FREQ=60 Va=120 Vb=120 Vc=120
WFa=1 WFb=1 WFc=1
#SEGS=0 Ilim=50 PHb=120º PHc=240º
Pressing EXECUTE now will cause that program to be executed and the V/I METER display to be active.
V/I METER:
FREQ=60.00 Va=120.0 Vb=120.0 Vc=120.0
SENSE=INT Vab=208.0 Vbc=208.0 Vca=208.0
PROGRAM #1 Ia=00.0 Ib=00.0 Ic=00.0
4.4.2 TRANSIENT EXECUTION
The UPC must be in Program Operate Mode to execute a transient and the executing program must
have a transient stored, this is indicated by #SEGS=1 (or more), in the lower left hand corner of
PROGRAM display. From any metering display, pressing the TRANS key will start a transient at positive
zero crossing of phase A. Pressing the TRANS key again will initiate a new transient instance, or stop
the transient if still active.
General steps to create a new
transient program are as follows.
1. Create or edit a program using the method described in section 4.5.1. Executing the
program at this point is optional.
2. Create or edit the transient portion of the program using the method described in section
4.5.2.
3. Execute the program as described in section 4.4.1.
4. Execute the transient by pressing the TRANS key. Pressing the TRANS key again will stop
the transient if still active.
