3013 Axis lubrication low or no air pressure.
Sheet 4 Plug 2 Pin-M
a) Check the incoming air pressure at the gauge and the lubrication oil level. Top-up the oil level and reconnect the air supply if necessary. 

b) If the same error code persists check for 24 volts at terminals 400, 413 and 414 with a voltmeter (TB1 in the power distribution panel). If there is no 24 volts, indicator-fuse 4 in the PDP may be faulty. 

c) If there is 24 volts at terminal 400 but not at terminal 413 then the air pressure switch is faulty. Remove the rubber boot from the switch body and check that the terminals are secure. 

d) If there is 24 volts at both 400 and 413, but not at 414 the lubrication float switch is at fault. Check the plug and socket are connected. 

e) If there is 24 volts at 414 then the fault lies from terminal 414 through to Plug 2, Pin-M and the 'Digital Input Board' in the control. Switch off the control and transpose the 'DI' boards situated in the lower rack to the left. 

f) Power-up the machine. If the fault disappears, or a different, unrelated error code shows-up, then the 'DI' board is faulty and a replacement is required. 

g) If the same error code persists switch-off the machine, remove plug 2 and check the continuity from pin-M to terminal 414. There may be a spare wire in the cable loom to utilize if wire 414 appears to be broken.

h) If the wiring is O.K. the fault may be with the 'Watchdog' board (WD 50x) in the control or corruption of the memory. If another control is available the 'Watchdog' boards can be exchanged to test. If the memory is to be reloaded remember to punch-out programme and tool information first (although an up to date back-up tape should always be held).
