11.1.2 Two blinks alarms
1) POWER FAILURE #1 o #2 o #3"
Cause: They occur when respectively phases U, V and W of the motor are
broken. This alarm occurs when at least one of the phase currents is
less than 6Aac while the applied frequency is different from zero.
Remedy: Verify the motor cables and motor windings continuity.
2) LOGIC FAILURE #1
Cause: It occurs when the real voltage between phase U and V is different
fom the desired.
Remedy: If the alarm occurs permanently, it is necessary to substitute the
logic.
3) LOGIC FAILURE #2
Cause: It occurs when the real voltage between phase U and W is different
fom the desidered.
Remedy: If the alarm occurs permanently, it is necessary to substitute the
logic.
4) HIGH CURRENT
Cause: It occurs when the output current amplifiers signal result higher than
Imax level (not controllable) for more than about 1 sec.
Remedy: If the alarm occurs permanently, it is necessary to substitute the
logic.
5) MAIN CONT. OPEN
Cause: It occurs during init by Can-Bus synchronisation with traction module
if main contactor doesn't close.
Remedy: Probable traction controller alarm.
6) KEY OFF
Cause: It's a warning that occurs if the Sicos module gives a key-off
command via Can-Bus.
Remedy: This warning disappears if the Sicos module switches off the
command.
7) CAN-BUS
Cause: It's a warning that occurs if the traction module is not connected or if
there is some problems on the Can-Bus line.
Remedy: Check the Can-Bus lines. If you want the EPS-AC working without
Can-Bus comunication turn to "Absent" the hardware setting "Can-
Bus" with the hand set.
To do it enter in the alarm config menu. Push at in the same time the
two right side buttons. This sequence will enter the hidden Zapi
menu. Roll up and down (buttons 1 and 2) until the "Hardware
setting " appears on the handset display. Enter it and roll with the left
side button until the "Can-Bus" text appears. Turn it to "Absent" with
the right side buttons.
