Status Indicators
5.6.1 Status LED
The status LED indicates the transmitter operation. When the transmitter is operating normally, the LED indicator
emits short flashes at a low rate when no commands activate, and at a higher rate when a command activates.
Some transmitters use a red LED only. Others use a multicolored LED that flashes GREEN when no problems
are present and changes to RED when problems are encountered. See the Status Chart below.
Table 1: Transmitter Status Chart
LED Indication
Possible Cause
LED is off
Transmitter is off
– switch transmitter ON
Batteries are dead
– replace batteries
Transmitter failure
– contact Cattron at
service
LED flashes at low rate
Transmitter is operating in a normal mode
LED flashes at high rate
Command Switch is pressed
LED flashes Red/Green (‘A’ series
only)
Batteries getting low
– change batteries at the next convenient
opportunity
LED flashes on-off at a slow rate
(½ second on and ½ second off)
Batteries getting low
– change batteries at the next convenient
opportunity
LED remains on continuously (LED
might flicker slightly)
A switch was activated at the time the transmitter was switched on, or a
general failure occurred that requires factory service. Ensure no other
switches are pressed while attempting to switch the transmitter on
LED will not light when ON/OFF

Replace batteries. If this does not correct the problem, the transmitter
must be repaired
5.6.2 Function Select LEDs
Two LEDs are used on some transmitters to indicate which control functions are active (such as hoist trolley A or
hoist trolley B; these are commonly used with pilot relays). When both are illuminated, both controls are active.
When both LEDs go out, neither control is active.
