To change this signal, press the “ + ” key on the machine display.
•
D0/1 : the status of the motor down signal produced by the CPU board and sent to the Bio servo
board to select a lower weight. When the letter D is followed by 0 , this means there is no
movement command; when the value is 1 , the CPU board is ordering movement.
To change this signal, press the “
−−−−
” key on the machine display.
•
EXXX : indicates the number of pulses produced by the weight stack motor encoder and
received by the CPU board. This value must increase when the motor moves to select a higher
weight, and decrease when the motor moves to select a lower weight. This value may be either
positive or negative.
•
F0/1 : the status of the alarm signal produced by the Bio servo board and sent to the CPU board
to disable movement. When the letter F is followed by 0 , this means there is no alarm; when the
reading is 1 , an alarm signal has arrived. Movement stops in this condition. The alarm status
will reset to 0 as soon as the button enabling the movement that caused the alarm is released.
Using this procedure, it is possible to identify various situations, some of which are listed below:
Problem Cause Solution
Replace the CPU board.
The status of the U and/or D
signals does not change when
the “+” and/or “-” keys are
pressed, and the motor does not
move.
The CPU board does not
produce the command signals.
Replace the keyboard.
Connector cable between the
CPU board and Bio servo board
is defective.
Replace the cable.
Bio servo board defective. Replace the Bio servo board.
Motor defective. Replace the motor.
Pressing the “+” and/or “-”
keys changes the status of the
U and/or D signals, and the
motor does not move.
Power supply defective. Check the motor power supply.
Connector cable between the
CPU board and Bio servo board
is defective.
Replace the cable.
The motor moves but the
encoder signal status does not
change.
Encoder defective. Replace the motor.
Mechanical problem.
Check the weight stack
selection system.
The motor moves, then stops
immediately because an alarm
signal arrives.
Low current limit setting on the
Bio servo board. Check the current limit setting.

ERO SENSOR STATUS
The part regarding the zero sensor, marked by the letter M, allows you to monitor the status of the
of the zero sensor signal. The LCD displays:
