NOTE: If the unit has a standard status LED, it will illuminate solid red during the transmitter’s
power down process. Once the power down process is complete, the transmitter will turn off and
the status LED will not be on.
NOTE: You must place the OFF-ON-START switch to the ON position after the unit is powered
up, and then switch to the START position to pull in the Machine Stop relay (for older XLTX
models, the user will have to position the OFF-ON-START switch into the START position once to
start the transmitter and a second time to pull in the Machine Stop relay).
3.2.4 Turning Off the Transmitter
The transmitter can be turned off by pressing the OFF-ON-START toggle switch down to the OFF
position. Once turned off, the Machine Stop relay in the receiver is immediately opened.
NOTE: Depressing the Machine Stop switch will also turn the transmitter off and open the
Machine Stop relay in the receiver. See Section 3.3 for more information on the Machine Stop
switch.
3.3 MACHINE STOP SWITCH (FOR EMERGENCY STOPPING ONLY)
When the Machine Stop switch is depressed, the Machine Stop relay in the receiver is
immediately opened.
Under normal operating conditions, the Machine Stop switch must be in the raised position or the
transmitter and system will not operate.
NOTE: The Machine Stop Switch is to be used for emergency stopping only, not for normal
system shut down.
3.4 POWER/STATUS AND BATTERY LED
The standard XLTX transmitter includes a Power/Status LED to let the operator know that the unit
is functioning and a Battery LED to indicate that the battery level is low (see Section 3.6.1 for LED
indication definitions).
NOTE: Single Status/Battery LED equipped units will indicate that the transmitter is on and the
battery level using the single LED (see Section 3.6.2 for LED indication definitions).
3.5 GRAPHIC USER INTERFACE
The LCD screen located at the center of the device provides visual information during the
operation of the XLTX transmitter. It is used to change configuration settings, confirm commands
being operated, provide two-way feedback, and display transmitter diagnostic information such as
battery life and signal strength.
3.6 NORMAL OPERATING MODE WITH STANDARD STATUS LED(S)
In normal operating mode, the XLTX utilizes the Power/Status and Battery LED(s) to represent
the watch dog timer within the CPU of the transmitter, the machine stop relay status, and when
the battery level is low.
3.6.1 Transmitters Equipped with Separate Power/Status and Battery LED Indicators
3.6.1.1 Watch Dog Indicator (Steady Slow Blinking Green Power/Status LED)
The blinking Power/Status LED represents the watch dog timer within the CPU of the unit. This
indicates that the transmitter is powered on.
