Cause:
- The safety loop can be broken, verify that the doors are all closed, the abort
switch is not active, etc. If the safety loop is open, no power is going to the
carriage driver board and this error will be displayed.
- For VLF engine, verify that there is 80 volts coming out of the PS3 power supply.
- For TS3, TS3/8, TS4 and TS8 engine, verify that there is 80 volts coming out of
the PS4 power supply.
- For the new TS8 engine (Power board 11-0872), verify that there is 48 volts coming out
of the PS4 power supply.
- For VLF engine only, verify that the fuses F12 and F20 are good. Fuse F20 protects the
80 volts power supply and fuse F12 protect the carriage driver board.
- For all engine, except the VLF engine, verify that the breaker CB4 is not popped out.
- For engine TS3 and TS3/8, verify that the relay K6 is working properly. For engine TS4,
TS8 and the new TS8, verify that the relay K2 is working properly.
- For VLF engine only. verify that the cables 10-1357, 10-1346, 10-1354 and 10-1367 are in good shape.
- Power driver board may be broken.
- The carriage motor may be burned, there may be one or two phases missing in the
carriage motor or the carriage motor may be stalling. All of these situations will
lower the voltage sent to the carriage driver board. Therefore, the carriage motor
may be the problem.
