1432
Communication timeout with other CPU was detected at the multiple
CPU high speed transmission.
Reset the CPU module and set it to RUN again. If the same error is
displayed again, a hardware failure may have occurred in the CPU
module. Please consult your local Mitsubishi service center or
representative, explaining the details of the problem.
1433
Error (Disconnected) with other CPU was detected at the multiple
CPU high speed transmission.
• Take a preventive measure against noise.
• Check if the CPU module is mounted on the main base unit correctly.
• Reset the CPU module and set it to RUN again.
If the same error is displayed again, a hardware failure may have
occurred in the CPU module. Please consult your local Mitsubishi
service center or representative, explaining the details of the
problem.
1434
Error (Disconnected) with other CPU was detected at the multiple
CPU high speed transmission.
• Take a preventive measure against noise.
• Check if the CPU module is mounted on the main base unit correctly.
• Reset the CPU module and set it to RUN again.
If the same error is displayed again, a hardware failure may have
occurred in the CPU module. Please consult your local Mitsubishi
service center or representative, explaining the details of the
problem.
1435
Error (Disconnected) with other CPU was detected at the multiple
CPU high speed transmission.
• Take a preventive measure against noise.
• Check if the CPU module is mounted on the main base unit correctly.
• Reset the CPU module and set it to RUN again.
If the same error is displayed again, a hardware failure may have
occurred in the CPU module. Please consult your local Mitsubishi
service center or representative, explaining the details of the
problem.
1436
The error of the multiple CPU high speed transmission main base unit
was detected at the multiple CPU high speed transmission (The error
of the multiple CPU high speed transmission was detected).
Reset the CPU module and set it to RUN again. If the same error is
displayed again, a hardware failure may have occurred in the CPU
module. Please consult your local Mitsubishi service center or
representative, explaining the details of the problem.
1437
The error of the multiple CPU high speed transmission main base unit
was detected at the multiple CPU high speed transmission (The error
of the multiple CPU high speed transmission was detected).
• Take a preventive measure against noise.
• Check if the CPU module is mounted on the main base unit correctly.
• Reset the CPU module and set it to RUN again.
If the same error is displayed again, a hardware failure may have
occurred in the CPU module. Please consult your local Mitsubishi
service center or representative, explaining the details of the
problem.
1439
The error of the multiple CPU high speed transmission main base unit
was detected at the multiple CPU high speed transmission (The error
of the multiple CPU high speed transmission was detected).
Reset the CPU module and set it to RUN again. If the same error is
displayed again, a hardware failure may have occurred in the CPU
module. Please consult your local Mitsubishi service center or
representative, explaining the details of the problem.

• A momentary power failure occurred in the power supply.
(The number of detected momentary power failures can be confirmed
by the QBF_ReadStatusEx function.)
• The power supply was turned off.
Check the power supply.
1510
On the redundant power supply base unit, the voltage of one of the
power supplies dropped.
Check the supply power to the redundant power supply module on the
redundant power supply base unit.
1520
In the redundant power supply system, a failure was detected in one of
the redundant power supply modules.
A hardware failure may have occurred in the redundant power supply
module. Please consult your local Mitsubishi service center or
representative, explaining the details of the problem.
1600
• The battery voltage of the CPU module has dropped to the specified
value or less.
• The lead connector of the battery in the CPU module is not
connected.
• The lead connector of the CPU module battery is not securely
engaged.
• Replace the battery.
• Connect the lead connector.
• Check the lead connector of the CPU module for looseness. Firmly
engage the connector if it is loose.
