Okuma Alarm-A 1826 Oil air lubrication illegal
The oil-air lubrication unit alarm/switch kept OFF for a second or longer.
A bad condition was caused on a lubrication of spindle by oil-air system.
Code
20->A pump of lubrication of spindle by oil-air is an overload condition.
21->Detection PS of oil-air decrease has continued to turn it OFF.
22->Detection PS of oil-air increase has continued to turn it OFF.
23->Detection PS of oil-air increase turned it off by the condition that a pump of lubrication of spindle by oil-air is acting.
24->Detection PS of oil-air increase has continued to turn it ON.
25->The oil-air lubricant pressure signal did not turn ON within 60 seconds after the whetstone oil-air pump output signal turned ON.
26->The oil-air lubricant pressure signal turned OFF after oil-air pump output signal ON.
27->The oil-air lubricant pressure signal did not turn OFF within oil-air pump stop timer.
28->A oil-air lubricant pressure signal OFF condition continued more than 2 seconds.
29->Detection PS of M SP.oil-air increase has continued to turn it ON.
30->The M SP.oil-air lubricant pressure signal did not turn ON within 45 seconds after the whetstone M SP.oil-air pump output signal turned ON.
31->The M SP.oil-air lubricant pressure signal turned OFF after M SP.oil-air pump output signal ON.
32->Detection PS of M SP.oil-air decrease has continued to turn it OFF.
33->A pump of lubrication of M spindle by oil-air is an overload condition.
Probable Faulty Locations

23->Inferiority of detection PS of oil-air increase.
24->Inferiority of detection PS of oil-air increase.
29->Inferiority of detection PS of M SP.oil-air increase.
30->Inferiority of detection PS of M SP.oil-air increase.
31->Inferiority of detection PS of M SP.oil-air increase.
32->Inferiority of detection PS of M SP.oil-air decrease.
33->There is a bad condition on a pump motor of a lubrication of M spindle by oil-air system/Inferiority of an overload switch/
Something mixed with a oil-air lubricant.
Measures to Take
20->Reset of an overload switch.

21->Exchange of detection PS of oil-air decrease.
22->Exchange of detection PS of oil-air increase.
23->Exchange of detection PS of oil-air increase.
24->Exchange of detection PS of oil-air increase.
29->Exchange of detection PS of M SP.oil-air increase.
30->Exchange of detection PS of M SP.oil-air increase.
31->Exchange of detection PS of M SP.oil-air increase.
32->Exchange of detection PS of M SP.oil-air decrease.
33->Reset of an overload switch. Exchange of a M SP.pump motor. An inspection of a M SP.oil-air lubricant.
