Ensure the correct controller is being used for this system.
When installed, ensure the STOP switch on the controller is in
the ‘RUN’ position and the ON/OFF switch on the controller is
set to ‘ON’. Ensure the controller is set to the same frequency
as the receiver. Refer to the controller manual for information
on checking and setting the controller frequency.
Activate a safe, non-motion function on the controller and
observe the green Carrier Detect LED on the receiver. If the
green Carrier Detect LED does not blink, check the green
Transmit LED on the controller. If the green Transmit LED is
not blinking, check and replace/recharge the controller
batteries, or replace the controller. If the green Transmit LED
on the controller is blinking but the green Carrier Detect LED on
the receiver is not blinking, replace the receiver.

interference
Check the system status display.
If the operational controller’s
address box in line 2 shows the code
EA
when a function is
commanded, the addresses for the controller and decoder do
not match. Check the address code displayed during the
decoder power up sequence. If the address is not correct,
replace the code plug. Refer to the
procedure later in this manual for information on setting the
address and replacing the code plug. If the displayed address
code is correct, the controller address code may be incorrect.
Check the controller manual for instructions on changing the
controller address code.
If the green Carrier Detect LED on the receiver circuit board is
on steadily, then there may be excessive RF interference on
the selected channel, or the receiver may be faulty. Check the
system status display code. The codes
ES
,
EA
,
Eb
,
EC
and
EF
in the operational controller’s address box in line 2 indicate RF
interference. Replace the receiver with a spare. If the
indications remain unchanged, then contact Cattron at
or perform a site spectrum analysis to
locate and correct the interfering RF source.
Primary

Dead battery pack
Controller set to wrong
address and/or

Faulty controller
Replace/recharge the battery pack.
Check the system status display code. If the operational
controller’s address box in line 2 shows the code
EA
, the
controller and decoder are not set to the same address. Refer
to the controller manual and check/change the address code
and frequency.
If the above checks do not correct the problem, then return the
controller to Cattron for repair.
