6.3.1 PERFORMANCE CHECK
The purpose of this paragraph is to provide a quick, yet thorough procedure that
allows the user to verify that the power source is operating properly. Always start
with the performance check flow chart.
The numbered comments below correspond to the circled numbers on figure
6.3.1 and provide detailed instructions relative to the referenced step.
1.
With input power applied and the input circuit breaker closed, some panel
lights should be on and all fans should be spinning. If there are no panel
lights or the fans are not spinning go to figure 6.3.2.
2.
Pressing the DIAG KEY then f3 KEYS should cause the LCD to display
INTERNAL VOLTAGES. Ignore BUS voltages at this time. The LVPS
shall be between 15 and 20 VDC. If the LVPS was outside of this range it
would cause an EMER OFF. If the display is not correct go to figure 6.3.3.
3.
The EMER OFF lamp should be off. If you suspect the lamp it's self is bad
press the EMER OFF button. This will cause an EMER OFF. Pressing
START RESET should clear the EMER OFF. If an EMER OFF cannot be
cleared go to figure 6.3.4.
4.
Pressing the OUTPUT then f2 KEYS shall cause the O2 display to be
active. This allows metering of inverter volts or CABINET VOLTS. Verify
the power source is in STANDBY or ON mode. Verify CABINET VOLTS
are OK. If not go to figure 6.3.5.
5.
Pressing OUTPUT then f3 KEYS shall cause the O3 display to be active.
This allows metering of SYSTEM VOLTS, the output terminals. With a
load applied verify the output volts or SYSTEM VOLTS are OK, if not go to
figure 6.3.6.
