3014 Hydraulic reservoir low.
Sheet 4 Plug 2 Pin-L
a) Visually check the hydraulic oil level in the sight-glass on the side of the hydraulic reservoir. Replenish if necessary.
b) If the same error code persists check for 24 volts at terminals 400 and 412 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 412 then the float switch is faulty.
d) If there is 24 volts at both 400 and 412 then the fault lies from terminal 412 through to Plug 2, Pin-L and the 'Digital Input Board' in the control.
e) Switch-off the control and transpose the 'DI' boards situated in the lower rack to the left. 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.
f) If the same error code persists switch-off the machine, remove plug 2 and check the continuity from pin-L to terminal 412. There may be a spare wire in the cable loom to utilize if wire 412 appears to be broken.
g) 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).
