3 General System Information
3.1 General Operation
1. Reset the STOP button located on the top left-hand corner of the transmitter by
rotating it clockwise or counterclockwise; the button will pop up. The transmitter
powers on when the STOP button elevates.
2. After turning on the transmitter power, check the Status LED on the transmitter for
any sign of system irregularities.
If the transmitter is
in good working order, the Status LED will display solid green for up to 2 seconds
at power on (no faults detected).
3. Press and hold both PB1 and PB2 at the same time for 1 second to activate the
receiver MAIN relays (Status LED solid green). When the receiver MAIN relays
are activated, the Status LED will change from solid green to solid orange (system
on). Then press any pushbutton on the transmitter to begin operation. Pressing
any pushbutton prior to executing the START command at start-up will result in no
signals transmitted (Status LED blinks orange).
NOTE:
If the Status LED does not change from green to orange, confirm that the
serial number and channel match between the transmitter and receiver.
4. In case of an emergency, press down the STOP button to disconnect the receiver
MAIN relays and the transmitter power (Status LED blinks 3 reds and then shuts
off). To resume operation after confirming safe conditions are present, rotate the
STOP button clockwise or counterclockwise; the button will pop up. Then press
and hold both PB1 and PB2 pushbuttons at the same time for 1 second to
reconnect the receiver MAIN relays.
5. After 5 minutes of inactivity (pushbutton not pressed) the receiver MAIN relays
temporarily disconnect. The Status LED blinks 3 reds and then shuts off. Press
and hold both PB1 and PB2 to resume operation.
6. Turn off the transmitter power by pressing down the STOP button. It will
disconnect the transmitter power and the receiver MAIN relays altogether (Status
LED blinks 3 reds and then shuts off).
