3.2.2
Turning On the Transmitter (with Optional Graphic User Interface Screen)
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 Magnetek logo appears on the LCD screen. Following the
logo screen, 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 on the screen, and then the MLTX2 will power
itself down.
After a successful initialization, the MLTX2 will enter the Normal Operation Mode and display the normal
operating screen. See Section 3.7 for more information on the Normal Operation Mode with Optional
Graphic User Interface.
NOTE: Holding the OFF-ON-START toggle in the START position for more than 5 seconds will put the
device into Setup Mode. For normal use release the START toggle once the Magnetek logo appears.
See Section 4.1.4.1 for more information on the Setup Mode.
3.2.3
Pulling In the Machine Stop Relay
Once the MLTX2 has been turned on (as described in Sections 3.2.1 or 3.2.2) and in the Normal
Operating Mode, the Machine Stop relay in the receiver can be pulled in by pushing the OFF-ON-START
toggle switch to the START position and then releasing.
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, then
push to the START position to pull in the Machine Stop relay (for older MLTX2 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: If the unit has the standard separate Power/Status LED and Battery LED, the Battery LED will
illuminate solid red during the transmitter’s power down process. Once the power down process is
complete, the transmitter will turn off and both LEDs will not be on.
NOTE: If the unit has a standard single LED, it will illuminate solid red during t
he transmitter’s power
down process. Once the power down process is complete, the transmitter will turn off and the LED will not
be on.
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.
