3010 Dangerously high temperature in control cabinet.

a) Check that the cooling fans on the rear of the control are rotating, and the air-vents are clear of obstruction. Any faulty cooling fans need replacing. Switch-off power to the control and allow time to cool-down (do not use compressed air inside control cabinet).

b) If the same error code persists 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 the programme and tool information first (although an up to date back-up tape should always be held).
