Most problems can be resolved by using the information provided in the table.
Problems And Probable Causes
Problem Probable Causes
Printer does not print
(serial RS232)
* Cable connection problem or invalid pin connections.
* Baud rate and format on serial port 1 does not match printer.
Printer is not ready or it is busy. Check CTS signal TB1 pin 7.
This signal must be high in order to transmit. Jumper pin 8 of
TB1 to pin 7 of TB1 CTS/RTS.
* Transmitter/receiver IC damaged (U6 MC145406).
Continuous output does
not update
* “TX CONTINUOUS” disabled (configuration Parameter 28)
* Cable connection problem or invalid pin connections.
* Baud rate and format on serial port 2 does not match receiver.
* Transmitter/receiver IC damaged (U6 MC145406).
Input port 1 not working * Baud rate and format on serial port 1 does not match host.
*Cable connection problem or invalid pin connections.
*Internal switch SW1 (CL/RS232) not set properly for input
type. *RS232 transmitter/receiver IC damaged (U6 MC145406).
*Current loop receiver IC damaged (U3 4N36).
Input port 2 not working * Baud rate and format on serial port 2 does not match host.
* Cable connection problem or invalid pin connections.
* Internal jumper JP3 (RS232/422/485) not set properly.
* RS232 transmitter/receiver IC damaged (U6 MC145406).
* RS422/485 transmitter/receiver IC damaged (RS422 {U10
75176} RS485 {U14 75176}).
“Er CtS” error message. * Cable connection problem. Check CTS signal TB1 pin 7. This
signal must be high in order to transmit. Jumper to pin 8 of TB1.
* Printer is not ready or it is busy.
* Transmitter/receiver IC damaged (U6 - MC145406).
“Err 13” error message
(Printer Error)
* This error occurs when the parallel output has been selected
for printing and the printer is busy, a printer fault has occurred,
or there is a problem with the cable.
Invalid weight display
or weight fluctuating
* Invalid calibration parameters. * Load cell or load cell input
cable problems.
