4.4.1 PROGRAM EXECUTION
To use Program Operate Mode, from any meter display press the
PROGRAM
key. The PROGRAM display
will become active. The most recently executed 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=120° PHc=240°
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 active 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 the transient at positive zero crossing of phase
A Pressing the
TRANS
key again will stop the transient if presently active, or initiate a new transient
instance.
General steps to create a transient program are as follows.
1.
Create or edit a program
using the method described in (
). Executing the program at this
point is optional.
2.
Create or edit the transient
portion of the program using the method described in (
).
3.
Execute the program
as described in (
).
4.
Execute the transient
by pressing the
TRANS
key. Pressing the
TRANS
key again will stop the
transient if still active.
The most direct method to create a transient event within a program is as follows.
1. From the V/I meter, press
PROGRAM
, enter the program number, press
ENTER
.
2. Press
EDIT
. Change steady-state values if desired, pressing
ENTER
after each entry.
3. Press
EDIT
again. Change transient segment values if desired, pressing
ENTER
after each
entry. Setting T to 0 in the first segment makes the transient a cycle based transient.
Continue pressing
ENTER
to create new segments.
4. Press
STORE
. Enter the number of desired events then
STORE
again.
5. Execute the program’s steady-state values by pressing
PROGRAM, EXECUTE
.
6. Execute the program’s transient values by pressing
TRANS
. Pressing the
TRANS
key again will
stop the transient if still active.
