NOTE: The Power/Status LED should be continuously blinking at all times. If the LED is not
blinking the transmitter will need to be rebooted to operate properly.
3.6.1.2 Machine Stop Relay Indicator (Rapidly Green Blinking Power/Status LED)
When the receiver is online with the transmitter and the machine stop relay is successfully pulled
in, the Power/Status LED will rapidly blink green.
NOTE: If the receiver inactivity timer times out, the transmitter will revert back to the watch dog
indicating status (steady slow blinking Green Power/Status LED). Following the procedure for
pulling in the machine stop relay in Section 3.2.3 will resume the rapidly blinking green
Power/Status LED if the machine stop relay is successfully pulled in.
NOTE: This LED function is only available on the 2.4 GHz and 900 MHz equipped transmitters.
On 433 MHz equipped transmitters, the watch dog indicator function in Section 3.6.1.1 continues
to operate after the machine stop relay is pulled in.
3.6.1.3 Low Battery Level Indicator (Blinking Red Battery LED)
The Battery LED will rapidly flash red when the battery level drops below 10%. The Power/Status
LED will continue blinking for the watch dog indicator and machine stop relay indicator status.
NOTE: If using a different battery pack than what the unit originally shipped with, the low battery
level indicator will be inaccurate unless the dip switch settings are set to the correct battery type
being used. See Section 3.1.3 for details to properly set the dip switches.
3.6.1.4 Shutdown Sequence Initiated Indicator (Solid Red Battery LED)
When the transmitter is turned off or if the machine stop is depressed, the transmitter will begin its
shutdown sequence. During the sequence, the Red Battery LED will illuminate solid.
NOTE: When the shutdown sequence is completed, all LEDs will turn off.
3.6.2 Transmitters Equipped with Single Status/Battery LED Indicator
NOTE: For specific LED function details, always refer to the transmitter drawings provided with
the system.
3.6.2.1 Watch Dog Indicator (Steady Slow Blinking Red Status/Battery LED)
The slow blinking Battery/Status LED represents the watch dog timer within the CPU of the unit.
This indicates that the transmitter is powered on.
NOTE: The Status/Battery LED should be continuously blinking at all times. If the LED is not
blinking the transmitter will need to be rebooted to operate properly.
3.6.2.2 Low Battery Level Indicator (Rapidly Blinking Red Status/Battery LED)
The Status/Battery LED will rapidly flash red when the battery level drops below 10%.
NOTE: If using a different battery pack than what the unit originally shipped with, the low battery
level indicator will be inaccurate unless the dip switch settings are set to the correct battery type
being used. See Section 3.1.3 for details to properly set the dip switches.
3.6.2.3 Shutdown Sequence Initiated Indicator (Solid Red Battery LED)
When the transmitter is turned off or if the machine stop is depressed, the transmitter will begin its
shutdown sequence. During the sequence, the red Status/Battery LED may illuminate solid.
