5.6 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 www.cattron.com/contact for

LED flashes at high rate
Command Switch is pressed
LED flashes Red/Green (‘A’ series

(½ second on and ½ second off)
Batteries getting low – change batteries at the next convenient

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.
