The diagram below indicates Up/Down/Stop/Test Keys and LED’s
The [Test] LED and key are computer controlled. The software supplied uses the [Test]
LED to indicate a test is in operation. The [Test] Key when pressed requests the
software to start a new test. This in turn will illuminate the [Test] LED.
Under computer control the power ON default speeds are overridden. These can now
be selected using the software control panel. Additional speeds can also be selected
that are not available in manual operation. E.g. Auto return speed. For more information
on the additional features refer to the Software Manual.
Note If power is lost to the machine, the computer speeds are lost. Re-establishing
the supply will return the machine to the power ON defaults speeds settings.
6.5. Alarms
6.5.1. Alarm Indicators
Crosshead Limit Alarm A crosshead limit alarm is flagged when the crosshead strikes
either crosshead limit switch and places the machine into a stop condition. The
indication that an alarm is present is by a Flashing LED indicator on either direction key,
reporting an alarm message on the software control panel and audible alarm.
The alarm direction is indicated by the Flashing LED indicator on the appropriate
direction key and alarm message on the software control panel. The alarm can be
cleared by backing the crosshead off the crosshead limit switch using the appropriate
direction key or by moving the crosshead limit switch away from the striker.
The diagram below indicates the direction alarm indicators.
Note The direction key which is indicating the alarm will be disabled. This is to protect
the crosshead limit switch in the event of incorrect direction selection.
