6.19 Checking Voltage at the Main Circuit Breaker
See Graphic: wc_gr003786
WARNING
Electric shock hazard. Only qualified personnel should conduct this
test. Do not perform this test if you or the machine are wet.
Complete this test with the machine running.
6.19.1 Remove the control panel front cover.
6.19.2 Using the AC voltage setting on the multimeter, measure the voltage
between the two incoming terminals (a) of the main circuit breaker.
There should be 230V±10%.
If 230V±10% was not measured, shut down the machine and
check the continuity of the wiring back to the short terminal strip.
Repair the wiring as necessary.
If 230V±10% was measured, continue.
6.19.3 Place the main circuit breaker in the ON position and measure the
voltage between the two outgoing terminals of the main circuit breaker.
If 230V±10% was not measured, shutdown the machine and
replace the main circuit breaker.
If 230V±10% was measured, the wiring and main circuit breaker
are functioning properly.
