the checks highlighted in the numbered boxes and listed here below:
(1) Check that LEDs 1 and 2 (green and yellow) are lit on the Display Board.
(2) Insert the tips of the tester onto pins 3 and1 of the CN4 connector on the Brake Board. They
should register about 220Vac or 110Vac according to the mains voltage.

Gently lift the fastons on the power supply socket on the equipment. Insert the tips of the
tester between the phase and neutral on the connector. They should register about 220Vac or
110Vac according to the mains voltage.
(4) Using the tester, measure the voltages on the CN1 connector on the Brake Board. They must
register:
• +12 Vdc between pins 6-2;
• +5 Vdc between pins 7-3.
If the Display Board is replaced, check that the upgraded SW version is installed or
proceed with the upgrade.
If the Brake Board is replaced, check that the correct SW version is installed or
