NOTE: The M-0315 PRIDE® Test Adapter can be used to simplify connections
to
the M-0290 for testing.
CORRECTION PROCEDURE
L
Connect the fixed 120
v,
60 Hz ac power to TBl-3 (HOT) and TBl-4 (NEUTRAL) . If the PRIDE has a Dc
SuWly, connect dc power
to
TBl-3
(+)
and TBl-4
H.
2.
Be
sure that the variable voltage
and
frequency source is turned off before connecting it
to
the
Sensing (potentiaU inputs TBl-5
(NEU'lRAL)
and TBl-6 (HOT) .
INPUT LOSS/FREQUENCY SAMPLE FAILURE SELF-TEST
1 .
__
Turn on the IX>wer suW1y. Verify that the
UNDER FRfJJtJElilCY
LED
blinks five consecutive times, stops
for about
1
sec, then repeats.
In this Self-Test mode, the
LED
will continue to blink until the
potential input voltage is detected.
2 . Turn on the potential input and adjust to 120 V ac, 60 Hz. Skip Step 3 if the LED remains off,
indicating that the system is operating correctly.
3. If any LED continues to blink after several seconds, this indicates the M-0290 has failed the
Self-Test mode. Refer to the SELF-TEST INDICATORS section, then check the external wiring,
connector orientation
and
fuses.
If
an LED
continues to flash, the LDlit is defective.

UNDERIOVER FREQUENCY DETECTION
1 . Slowly decrease the frequency of the potential input from 6 0 Hz until the UNDER FREQUENCY LED
turns on.
2 . The measured frequency level should be equal
to
the Under Frequency setpoint ±.O.o2 Hz.
3. Return the input frequency to 60 Hz.
4 .
Slowly increase the input frequency from 60 H z until the
OVER FREO
lJE1iCY
LED
turns on.
5 . The measured frequency level should be equal to the OVer Frequency setpoint ±O.02 Hz.
6 . Return the input frequency to 60 Hz.
UNDERIOVERVOLTAGE DETECTION
1 . Slowly decrease the input voltage from 120 V until the
UNllERl/OLTAGE LED
turns on.
2 . The measured voltage should be equal to the lJndervoltage setpoint
±.2%.
3 . Return the input voltage to 120 V.
4 .
Slowly increase the input voltage until the
O\IERVOLTAGE LED
turns on.
5 . The measured voltage should
be
equal
to
the lJndervoltage setpoint
±.2%.
