Display Messages - Corghi EM 7240 Manuel D'utilisation

The machine can recognise a certain number of malfunction conditions and signals them
to the user by visualising the relevant messages on the displays.
A 3 wheel not suitable for performing the sensitivity calibration, use a wheel of
average dimensions (typically 5.5"X1440") or larger but with a weight that
does not exceed 40 kg.
A 5
Incorrect dimension settings for an ALU programme. Correct the set dimensions.
A 7 The machine is temporarily not enabled to select the programme requested.

Lower the guard to perform the wheel spin.
In machine versions with the spin push button, release either the START but-
ton or the push button during the spin.
Carry out the spin holding down both the START button and the push button.
E 1 Absence of sensitivity calibration.
Perform the sensitivity calibration procedure.
E 2 Error condition on sensitivity calibration.
Repeat the sensitivity calibration, paying attention to the first spin, which
must be performed with the wheel like the subsequent spins.
