SECTION 3 - TROUBLESHOOTING
Updating the Software
To update the software, complete the following steps:
1. Format the USB thumb drive to FAT32.
2. Copy the current
software.pkg file on a USB
thumb drive.
There cannot be other files on the
USB thumb drive.
3. Download the current
software.pkg
file. If
the chiller is running, put it in the local mode, so
the SC-EQ does not affect the chiller operation
during the software update.
4. Insert the USB thumb drive into the J3 port on
the SC-EQ board. The software update starts au-
tomatically and the fault LED flashes quickly dur -
ing the update process.
5. If it does not start automatically, cycle power to
the SC-EQ board by removing and reconnecting
the power plug on the SC-EQ board.
6. When the software update is completed, the SC-
EQ reboots. All LEDs go out and then on again. A
typical update takes more than 5 minutes.
7. When the SC-EQ Fault LED is off for 30 s, the
firmware upgrade is complete. The USB thumb
drive may can removed.
