Be sure to frequently check meters and indicators for
proper operation, or any machine water, oil, fuel leaks, etc.
The above table gives standard values. They may vary
slightly depending on operating conditions and other
factors.
In single-phase load operation, check the current of L1, L2,
and L3 phase with the ammeter, by turning the ammeter
change-over switch.
Each current should be balanced if unbalanced. Change
load connections so the current of L1, L2, and L3 is equally
balanced. Make sure that the current of each phase does
not exceed the rated one.
Lamp marked ＊ glows while low speed idling is kept for a
few seconds by ambient temperature. (See 4-2)
