6.5.4. Motor Drive Alarm
The motor drive alarm is flagged in the same way as the emergency stop alarm.
(Direction and Stop LEDS flashing) This alarm can be triggered by a number of
conditions. These conditions are, Motor Position Alarm, Motor Velocity Alarm, Motor
Over Current Alarm, Motor Drive Temperature Alarm, Motor Drive Over/Under Voltage
Alarm, and Encoder Fault.
To clear the motor drive alarm and indicators select ‘OK’ on the software alarm panel.
This panel automatically appears when an alarm condition is present. If the alarm
persists turn the machine OFF, wait until the machine cools to room temperature and
power back ON. If the fault continues, turn OFF machine, isolate from supply and call
TINIUS OLSEN service department.
Note Resetting the motor drive alarm by powering the machine OFF and ON again
may require restarting the software.
6.6. Auxiliary Equipment
Auxiliary Port
The auxiliary port is located at the front right hand side of the machine’s base. This port
allows connection to a range of external equipment, enabling the machine to cover a
greater scope of testing. The type of equipment frequently connected are
Extensometers and LVDT Transducers. Use of this type of equipment removes inherent
errors that are associated with material testing.
The diagram below indicates the location of the Auxiliary port connector.
This section does not cover the installation of auxiliary equipment, refer to the
appropriate installation/operating manuals.
