Solution
˚ Try to upload the project
again.
If the problem persists after
several successfully uploads,
contact Neets or your local
distributor.
˚ Make sure that there is a SD
card inserted in the Control
System. (Look at the rear
panel)
˚ After doing one of the above,
remove the power to the
Control System for 20
seconds before reconnecting
the power again.
˚ Turn off the power to the
Control System for 20
seconds before turning the
power on again.
˚ If the error is not resolved
contact Neets or your local
distributor.
˚ Check to confirm that the
serial number used in Project
Designer matches the Neets
extension unit.
˚ Check the network or RS-232
connection from the Control
System to the Neets
extension unit.
˚ The Neets extension unit has
a different firmware than the
one in the Control System.
˚ Please upgrade the firmware
by plugging in the USB cable
from the Neets extension unit
into a PC running Project
Designer and follow the
instructions.
