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
(LP Bio servo) is defective.
Replace the cable.
Bio servo board (LP Bio servo)
defective. Replace the Bio servo board
(LP Bio servo).
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
(LP Bio servo) 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, although it is far
from one end.
Low current limit setting on the
Bio servo board (LP Bio servo
).
Check the current limit setting.
6.1.4. S
OLENOID
The part regarding the solenoid allows you to monitor the status of the signals exchanged between
the CPU board and the Bio servo board. The LCD displays:
•
A0/1 : the status of the motor up signal produced by the CPU board and sent to the Bio servo
board to activate the solenoid. When the letter A is followed by 0 , this means that there is no
enable command; when the value is 1 , the CPU board is sending the enable command to select
the additional weight.
To change this signal, press the “ Enter ” key on the machine display.
•
R0/1 : the status of the solenoid signal produced by the Bio servo board and sent to the CPU
board to monitor whether it is selected. When the letter R is followed by 0 , this means that the
solenoid is not enabled; when it is 1 , the solenoid is enabled. Under normal operating
conditions, the values of A and R must be equal: A0R0 and A1R1. In fault conditions you will
see A1R0.
Using this procedure, it is possible to identify various situations, some of which are listed below:
