the Color Change power LED turns on. If the power

 

LED does not turn on, the problem is probably

 

caused by a bad connection. The nut on the connec-

 

tor must make at least 5 complete turns to ensure a

 

good connection. If the power LED still does not

 

light, the cable or board is bad.

 

 

 

• Check the color change board DIP switch settings.

 

See the Installation manual.

 

 

 

• Check the fluid plate board DIP switch setting. An

 

incorrect setting will not cause E-12 alarms, but a

 

correct setting will help prevent E-12 caused by elec-

 

trical noise. See the Installation manual.

 

 

 

• Check EasyKey software version (displayed at power

 

up for all versions and when the lock key is pressed

 

for version 2.02.000 and above). If older than

 

1.06.002, upgrade. Be sure to save settings through

 

BWI or AWI before upgrading, as they will be erased.

 

 

 

• The sticker on the color change board shows the

 

software part number and version, for example

1.01. If the version is older than 1.01,

 

replace the board.

 

 

 

• If all software versions and DIP switch settings are

 

correct and you still have E-12 alarms, then the sys-

 

tem has a bad connection, bad cable, or bad circuit

 

board. Use a multimeter on the CAN connectors to

 

test whether there is a good connection between

 

systems. If there is, you have a bad circuit board. If

 

there is not, you have a bad connector, connection,

 

or cable.

Fluid system is producing too much or too little flow.
