LEDs Status Troubleshooting
Normal operation. This is the
normal functioning status of
the Heaters Control Assembly
PCA.
• This is the normal functioning status of the
Heaters Control Assembly PCA.
No Power. The PCA is not
receiving 24V nor +512C
power from the PrintMech.
• Check the printer connected to the power
source.
• Are the switches of the power inputs in the
on position.
• Have either of the RCCB/GFIs been tripped,
if they have reset them.
• Check the AC cables to the Heaters Control
board.
• Check the fuses have not blown.
• Replace the Heaters Control Assembly
⇒
page 465.
No 24v Power. The PCA is
receiving +5 volts, but not 24
volts from the PrintMech.
• Check the connection between the PSU and
the PrintMech PCA and Heaters Control
PCA.
• Replace the Printmech
⇒ page 482.
• Replace the Heaters Control Assembly
⇒
page 465.
Halt status. This configuration
of LEDs indicate that the
printer is in the HALT
condition. This is could be a
normal part of the printer
initialization, before 24v has
been activated. However if it
continues after the
initialization, this would
indicate a problem.
This is a normal status when resetting the
Heaters Control Assembly and before applying
the 24v.
Halt status with 24v present.
This configuration of LEDs
indicate that the printer is in
the HALT condition. This
could be a normal part of the
printer initialization. However
if it continues after the
initialization, this would
indicate a problem.
If this is the status after resetting the Heaters and
there is no system error check the following:
• Check that the window is not open in error.
• Check the cables to the Heaters Control
assembly are correctly connected. Check the
other connections to the other PCAs
• Replace the Heaters Control Assembly
⇒
page 465.
The relays are not activated
• Check all the connections in the Heaters
Control PCA (Chinda connection)
• This status is normal if the Heaters Control
assembly has been turned off from the Front
Panel.
Error Status. The relays have
been enabled, but they are
inactive.
• Check if the window is open.
• Replace the Heaters Control Assembly
