6.5. “THE EQUIPMENT IS BLOCKED” MESSAGE ON THE
DISPLAY
This error message can be caused by:
• loss of communication between the lower and upper assemblies;
• the AT driver has detected an error condition, causing it to generate an alarm and store the error
code in memory.
• problem on the emergency button.
To optimize the troubleshooting procedure, follow the steps below:
1. Access the item “TROUBLESHOOTINGÆAUTOMATIC TESTÆ SERIAL PORTS
TESTÆLow Kit COM Test”. If the outcome of the test is negative, check the components of
the link between the upper and lower kit, in particular:
• check that the wiring of the various cables (TRM-19 and TRM-20) is not damaged, in
particular the cables of the “emergency signal” and of the “reset” by referring to paragraph
2.7. “Wiring”, using the Test Box Excite.
• try replacing each of the circuit boards in turn (display board or digital plan board and AT
driver board) and check whether the communication works.
If the outcome of the test is OK move on to step 2.
2. Access the item “TROUBLESHOOTINGÆAUTOMATIC TESTÆInverter Test”. If the
outcome of the test is negative, check the error code stored in the “ERRORS LOG” and
perform the corresponding troubleshooting procedure, if the outcome is OK advance to step 3.
3. The machine lockout problem has to do with the handling of the emergency signal:
• check that the emergency button is not pressed;
• check that the cord, linked to the emergency button, is not to taut so that it keep the
emergency button contact open;
• check that all the cables linked to the emergency device management are properly connected
and in a good state of wear.
WARNING: if the display board detects an error condition during the tread belt motor
movement, it displays the error message and turns off the AC motor by the AT driver.
If you update the machine to the proper SW version, according to what we reported in
the Technical Newsletter, the message displayed in the event of a “Machine lockout”
condition has been modified to also include the cause of the error in parentheses:
• (COM), for errors connected with the serial link.
button. • (EMER), for errors connected with the emergency
• (error code), for errors generated by the low kit.
