MiniOPD’s Specific Alarms
Date:03/12/2010
The new MiniOPD consists of 2 fast-communicating microprocessors. One microprocessor is located
in the Regulation board (as in standard OPDs); the second one is located in the Power board.
Thanks to this new configuration, the MiniOPD features some types of alarms that are not included in
the OPD series. These alarms have been renamed, so as to guarantee maximum compatibility with
those who already use the OPD series.
MiniOPD’s specific alarms are listed in Table 1:
Alarm Description
A.10.0 Minimum voltage of Power circuit
A.10.5 Overcurrent alarm detected by Power board
A.10.6 Communication alarm: communication fault with Power board
A.10.7 Alarm due to Power board fault (Micro’s watchdog)
A.10.8 Alarm due to wrong power supply in the Power board (15V wrong)
A.10.15 Alarm - Brake (hardware)
Table 1
These alarms take the form of sub-alarms of alarm A.10, to indicate that they all depend on the
Power board.
If Alarm A.10.0 – Minimum Voltage of Power Circuit – occurs first, followed by a second alarm from
the Power board (typically a Communication Alarm or 15V Wrong Power Supply Alarm), the latter
alarms are not shown by the Drive, as they are a direct consequence of alarm A.10.0.
