6.4. TEST PROCEDURE DURING USE
During normal machine operation, the machine checks the components to detect any malfunctions.
The following problems may be detected:
6.4.1. W
EIGHT STACK MOTOR FAILURE
If the machine detects a failure on the weight stack motor, it may be caused by:
1. Mechanical problem
If the CPU board detects an alarm signal 3 consecutive times out of 3 attempts carried out
approximately 10 seconds apart, this means that there is something preventing movement. In
this case, the machine displays the following message on the LCD:
W G H T . S T A C K P R O B L E M =
F A I L
To exit this error condition, carry out the checks described in paragraph 6.9. “The LCD displays
the message “Weight stack problem = fail””.
This is a BLOCKING error, meaning that it prevents the machine from being used.
2. Motor – encoder problem
If the CPU board receives no encoder signal during movement, this means there is no movement
due to a probable motor fault, or that there is movement but it is not detected by a defective
encoder. In this case, the machine displays the following message on the LCD:
W G H T . S T A C K P R O B L E M =
G E N E R I C
To exit this error condition, shut off the machine, switch it back on and see which error appears
on the LCD display. Carry out the checks described in paragraphs 6.10. “The LCD displays the
message “Weight stack problem = motor”” or 6.11. “The LCD displays the message “Weight
stack problem = encoder””.
This is a BLOCKING error, meaning that it prevents the machine from being used.
6.4.2. S
EAT MOTOR TEST
If the machine detects a failure on the weight stack motor, this may be caused by:
1. Mechanical problem
If, during movement and after receiving the normal alarm message, the CPU board receives 3
more in 3 movement attempts carried out approximately 10 seconds apart, this means there is
something preventing movement. In this case, the machine displays the following message on
the LCD:
