Disable
1. Disable functions as shown. Refer to Section 4.4,
System Setpoints
, for procedure.
2. Confirm settings to be tested.
3. Connect inputs in Configuration V1 designated previously. Set the V.T. Configuration (Section
4.2) as V
A
. Refer to Section 6.4,
Input Configurations
for configuration.
4.
Pickup Test
:
NOTE
: When using single-phase frequency sources, connect the source to one voltage input.
a. Set the voltages to the Nominal Frequency. Set the pickup less than nominal frequency.
b. Press and hold the
TARGET RESET
button in, then slowly decrease the frequency of the
input voltage until the
FREQUENCY 81 O/U
LED illuminates or the pickup indicator operates
on the computer target screen. The level of operation will be equal to
P
Volts
0.1 Hz.
c. Release the
TARGET BUTTON
, then return to nominal input frequency. The
OUTPUT
LED
will extinguish.
d. Press
TARGET RESET
button to remove targets.
e. Set the pickup greater than nominal frequency. Repeat Step b through d, except you will have
to slowly increase the frequency of the input voltage.
5.
Time Test
: With output contacts being connected to the timer, input (
P
– 0.5) Hz and start timing.
The operating time will be (
D
) cycles within
–
1 to +3 cycles or
1%.
6. Complete the testing for the remaining 81 functions by repeating Steps 4 and 5, above.
7. If testing is complete, enable any functions disabled for this test. If further testing is desired,
check the proper functions to disable for the next test and continue from this configuration.
