6 Operating Procedures
6.1 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. Turn on the transmitter power by
inserting the power switch key and rotate to ON ( I ) position.
2. After turning on the transmitter power, check the Status LED on the transmitter for any
sign of system irregularities (
see Section 6.4.1 Transmitter Status Indications on
page 37
). 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. Rotate the power switch key further to the START position and hold it there for up to 2
seconds (Status LED solid green). When the receiver MAIN relays are activated the Status
LED will change from solid green to solid orange (system on). The power switch key will
retract back to the ON ( I ) position when released. The same START position becomes an
auxiliary function thereafter. Pressing any pushbutton prior to executing the START
command at system startup will result in no signals transmitted (Status LED blinks
orange).
4. Press any pushbutton on the transmitter to begin operation. During transmitter inactivity
(pushbuttons not pressed), the transmitter will automatically switch to Standby mode, with
an orange blink on the Status LED at every 4-second interval. Always turn off the
transmitter power when not in use to save battery power.
5. In case of an emergency, press down the STOP button to disconnect the receiver MAIN
relays (Status LED blinks 3 reds and then shuts off). To resume operation, rotate the
STOP button clockwise or counterclockwise. The button will pop up. Then execute the
START command to reconnect the receiver MAIN relays. For safety, executing the START
command is required every time the transmitter is turned on or after every STOP button
reset.
6. After 5 minutes of inactivity (pushbutton not pressed) the receiver MAIN relays are
temporarily disconnected (
see Section 4.1.5 on page 23
). The Status LED blinks 3 reds
and then shuts off. Press any pushbutton or execute the START command to resume
operation (
see Section 4.1.4 on page 22
).
