Final Testing And Adjustment - Eaton Power-Sure 700 Instruction Manual

Final testing and adjustment

8. After calculations are complete, place DC voltmeter
on the 20 V scale and check between TP2 and TP GND
on control card. Adjust pot P1 so meter reads DC level
calculated in Step 7 for all three phases.
N otes: If adjustments in Steps 6 and 7 are not possible,
replace control card # 49120/407415 and repeat Steps
6 and 8.
N otes: Be sure to turn power off when replacing circuit
boards.
Be sure AC input is stable when making this
N otes:
adjustment. If the input changes, you must
re-calculate.
N otes: Output voltage correction is a "stepped correction" ,
adjusting P1 will not cause a smooth change in
output voltage as it is adjusted.
9. Turn the unit off. Plug in TB2 Molex connectors to all
the control cards #49120 / 407415.
10. Replace connectors K1 and K2 on over/under detect
#35867 .
P1 pot turned clockwise = decrease in output voltage
N otes:
and counter-clockwise = increase in output voltage.
By changing this adjustment on phase 1, you may
see the output voltage change from line to neutral
on two phases. It is best to use procedures in
Steps 1–9 adjusting.

Final testing and adjustment
1. Connect AC voltmeter to output of system with proper
meter scale selected.
On three-phase systems, connect your AC voltmeter
N otes:
across the output phase to neutral.
2. Disconnect customer's loads.
3. Energize system.
4. Verify the output is within specifications. If not, adjust
P1 on control board, for the appropriate phase. See
adjustment procedure on page 22.
N otes: On three-phase systems, be sure and check all
three phases.
If the main AC breaker trips or there is no output
N otes:
voltage, disable the over/under detect circuit #35867
by disconnecting K1 and K2 connectors, then
calibrate the control boards if the output voltage is
out of spec. See control card adjustment procedure
on page 22.
5. Turn the input circuit breaker off.
6. Connect customer's equipment.
7 . Energize system.
8. Repeat Step 4 and adjust as needed.
9. Be sure over/under detect is connected and if input
breaker trips or there is no output voltage, re-calibrate
the detect board or replace board if defective (see
adjustment procedure on page 22).
