8.1 Transmitter Operating Steps
1. Make sure the two “AA” NiMH rechargeable batteries are installed correctly. Please note the polarity
of the batteries.
2. Status lights _To operate the transmitter, please rotate the power key on the top-left corner clockwise
to “on” position. The status LED (green and red) will be steady “on” for 2 seconds and then “off”. If
the transmitter Status LED displays a red blinking light that is “on”  0.1 second and “off”  1.9
seconds, or no light at all, this indicates the transmitter with batteries needs to be recharged. For battery
charging or replacement, please refer to instruction next page.
3. When any function pushbutton is depressed, the transmitter Status LED displays a red blinking light
that is “on” 0.1 second and “off” 1.9 seconds. If the voltage is low, the transmitter Status LED
will be “on”0.1 second and “off”1.9 seconds, this indicates the transmitter with batteries needs to
be recharged. Continuous operation will cause the transmitter battery power exhausting and cannot
operate at all.
4. EMS & Restarting _ In case of an emergency, press down the red emergency stop button (EMS) will
immediately deactivates the transmitter and receiver MAIN relay. (do not rotate the power switch to
OFF first)
Shutting Off the Transmitter(POS) _ (Mode 0) To disconnect the transmitter power just turn the power
key to “off” position. When the power key is switched from “on” to “off”, the transmitter will also
send a “Stop” command to the receiver for 3 seconds, the red status light flashes 3 times and at the
same time deactivate the MAIN relay.
Shutting Off the Transmitter(POS) _ (Mode 1) To disconnect the transmitter power just turn the power
key to “off” position. When the power key is switched from “on” to “off”, the transmitter will also
send a “Stop” command to the receiver for 3 seconds and at the same time deactivate the MAIN relay.
5. The emergency stop button is a right-rotate momentary spring-return type. To turn on the transmitter
and activate the MAIN relay, please elevate the emergency stop button again and rotate the transmitter
power key to “ON” position.
6. Note that the transmitter cannot be hit by outer force, so that malfunction can be prevented.
7. The operating temperature is -10 ~ +60℃. Avoid operating the transmitter in high temperature
workshop. If operating temperature is higher than 80℃, the auto shutdown protection installed inside
CPU will shut down the transmitter and deactivate the MAIN relay.
8. To operation normally, the battery power must over 2.2V. If the voltage is lower than 2.2V, the
system cannot be started and low voltage will be showed until the MAIN is completely shutdown.
9. If the power voltage is lower than 2.2V when transmitter is operated, the LV code will be “1” and low
voltage status light will be shown. For standard system, the transmitter will stop sending signals
when voltage is lower than 2.0V. But for EN ISO 13849-1 version, the transmitter will stop sending
signals when voltage is lower than 1.8V.
