4. Operating Procedures
4.1. General Operation
a. Reset the red emergency E-STOP button located on the Right hand side of the
transmitter by pulling it outward or rotating it clockwise.
b. 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 constant green for up to 2 seconds at power on (no faults detected).
c. Press the green START button for up to two (2) seconds to activate the receiver
mains. When the receiver MAIN relays are activated the Status LED will change from
constant green to constant orange (system on). The same START position becomes
an auxiliary function thereafter. Then press any pushbutton on the transmitter to
begin operation. Pressing any pushbutton prior to executing the START command at
system startup will result in no signals transmitted (Status LED blinks orange).
d. In case of an emergency, press down the E-STOP button to disconnect the receiver
MAIN relays and the transmitter power. To resume operation, rotate the E-STOP
button clockwise, the button will pop up. Then rotate the power switch key to the
START position for up to 2 seconds to reconnect the receiver MAIN relays. For
safety, executing the START command is strictly required every time when the
transmitter is turned on or after every E-STOP button reset.
e. After 1 minute or 5 minutes of inactivity (pushbutton not pressed) the receiver MAIN
relays are temporarily disconnected. Press any pushbutton or execute the START
command to resume operation. The receiver MAIN relays are also temporarily
disconnected when the system encounters strong radio interference, dead spots, low
battery condition, and system out of operating range.
f. Turn off the transmitter power by pressing down the E-STOP button, it will disconnect
the transmitter power and the receiver MAIN relays altogether (Status LED blinks 3 reds
and then shuts off).
