remove the JP2 jumper (refer to JP2 setting on page 15 & 16) then the MAIN relay will remain
closed until the “Stop” command is received or the main power source to the crane or equipment
is turned off.
5.
EMS & Restarting
_ In case of an emergency, press down the red EMS button will immediately
deactivate the transmitter power and receiver MAIN relay. When EMS button is activated
(depressed), the green blinking lights on the transmitter status LED will disappear (refer to
transmitter status LED display on page 28).
To reactivate the transmitter power and the receiver
MAIN relay, just pull the red EMS button upward
(depending on JP1 jumper setting on page 15 & 16)
.
6.
Interlocking Pushbuttons
_ For both 3000F & 3000D models the top 3 sets of motions
(pushbutton #1 ~ #6) are interlocked to its self so no conflicting commands can take place for
safety purpose. For example, pressing the Hoist “UP” and Hoist “DOWN” pushbutton
(pushbutton #1 & #2) simultaneously will result in no command being sent.
7.
Initial Start-up Code
_(POS only) Please note that, if JP1 is shorted (without the START
function), the receiver unit hence must receive an
“Initial Startup Code”
from the transmitter
in order for its MAIN relay to be energized. What this means is that the transmitter can only
activate the receiver MAIN relay as long as the operator is within the receiving range. For
example, if the operator turned “on” the transmitter in a different area of the facility (beyond 300
feet from the receiver location), then he will not be able to control the crane when he approached
within 300 feet. If this happens, the operator would have to resent the initial startup code by
reenact the Startup Procedure.
8.
Shutting Off the Transmitter
_ To disconnect the transmitter power and the receiver MAIN
relay, just pull out the transmitter power key or press down the red EMS button.
9.
Battery Replacement _
The transmitter Status LED will display a blinking red light that is “on”
0.1 second and off “2.0 seconds when the transmitter battery power falls below the safety
operating voltage, please refer to the table on page 25 for transmitter status LED display
information. For battery replacement, just unscrew the battery cover located on the backside of
the transmitter handset with a (+) head screwdriver (refer to the diagram below). When changing
batteries, do make sure that the batteries are installed correctly. The marking inside the battery
holder will tell you which side is positive (+) and which side is negative (-). The battery holder
will also tell you which side of the holder is facing up and which side is down.
