The RESET button for each motor will send an initialisation string to reset the motor.
This can be used to aid motor maintenance procedures. Please note; if a RESET
button is pressed the motors MUST be re-homed before the machine is operated.
The series of flags, labelled Bk through to Bt are status flags for each motor. The
meaning of each flag is described in Table 6.11.1.
The HOME button allows the operator to re-home the motors to the 0.5% catalyst
position. This button can be used to clear a “Motor reference lost – re-home motors”
fault.
The + button allows the user to increment the catalyst percentage; the motors will
move to update the position.
The – button allows the operator to decrement the catalyst percentage.
In combination, the + and – buttons allow the user to drive the motors up and down
the ratio arm to test the ratio drive is moving freely and as expected.

up or down arrows, the operator can scroll through list of machine inputs and monitor
their values.
