Turning On the Transmitter (with Standard Status LED Indicator(s))
3.2.1.1 Transmitters Equipped with Separate Power/Status and Battery LED Indicators
First, the Machine Stop switch must be in the raised position (pulled out). Next, push the OFF-ON-
START toggle switch to the ON position; the Power/Status LED lights up as a solid green color.
Following the Power/Status LED turning on and illuminating, the unit will perform a routine initialization.
During initialization, the MLTX2 scans for any switches or motions that may be on during power up. If any
switches or motions are on, the failure will be displayed as a solid red Battery LED, and then the MLTX2
will power itself down.
After a successful initialization, the MLTX2 will enter normal operation mode and display the normal
operating status LED indications. See Section 3.6 for more information on the normal operation mode
with standard status LED.
3.2.1.2 Transmitters Equipped with Single Status/Battery LED Indicator
First, the Machine Stop switch must be in the raised position (pulled out). Next, push the OFF-ON-START
toggle switch to the ON position. The unit will perform a routine initialization.
During initialization, the MLTX2 scans for any switches or motions that may be on during power up. If any
switches or motions are on, the failure will power the MLTX2 down.
NOTE: There will be no LED indication of the failure on the Single LED equipped transmitters. If the
Battery Status LED does not go into slow blinking mode as detailed in Section 3.6 after 15 seconds,
reboot the transmitter by turning the OFF the transmitter and then turning the transmitter back ON.
After a successful initialization, the MLTX2 will enter normal operation mode and display the normal
operating status LED indications. See Section 3.6 for more information on the normal operation mode
with standard status LED.
