INTRODUCTION
The Alpha 500 series are highly reliable industrial remote control systems. The versatile
features of the Alpha 500 series permit its use in many different remote control applications.
They can be used to control cranes, hoists, trolleys, mining equipment, building construction
equipment, automatic control systems, and many others.
The Alpha 500 series radio control system incorporates numerous redundant safety circuits that
guaranty maximum security and ensure the system is resistant to outside interference. The
major features of the Alpha 500 series are as follow:
* The syste m uses advanced microprocessors which utilizes highly evolved software that
have redundant error checking and correcting capabilities to ensure 100 % error-free
transmission, decoding, and control of the output relays. These highly evolved software
include CRC (Cyclic Redundancy Check codes) and Hamming Codes.
* To insure maximum operating safety, the Alpha 500 series incorporate many safety features.
Some of these safety features include receiver self-diagnosing, transmitter pushbutton
self-diagnosing, transmitter low voltage detection/warning, transmitter/receiver auto
shutdown after 1 minute of transmitter low voltage warning, and receiver MAIN
deactivation during transmitter non-usage (programmable from 0~30 minutes).
* The encoder/decoder system utilizes advanced microprocessor. The availability of 32,768
sets of unique ID codes will ensure that only commands from the matching control
transmitter can be carried out without any interference from other radio systems. A special
programmable inte grated circuit is used to insure the unit can not simultaneously command
conflicting movements.
* Full SMT design for system stability.
The Alpha 500 series radio control system consists of a transmitter handheld, a receiver unit, and
a six -foot (2-meter) output cable. The transmitter casing is molded using an industrial strength
composite material which is impervious to dust, water, oil, acids, alkaline, heat, sunlight, and as
well as being resistant to deformation due to long term use in harsh environments. The
pushbuttons are also constructed from industrial strength composite material with a minimum of
up to one million cycles. For power saving, the transmitter unit uses special high efficiency
power saving circuits that requires only two “AA” alkaline batteries (UM-3).

SAFETY INSTRUCTION
The Alpha 500 systems are relatively simple to use. However, it is very important to observe the
proper safety procedures during operation. When use properly the Alpha 500 systems will
enhance productivity and efficiency in the workplace.
The following instructions should be strictly followed:
1. Make a daily check of the transmitter casing and pushbuttons. Should it appear that
anything could inhibit the proper operation of the transmitter unit, it should be immediately
removed from service.
2. The transmitter voltage should be checked on a daily basis. If the voltage is low, the two
"AA" alkaline batteries should be replaced.
3. The emergency stop pushbutton (EMS) should be checked at the beginning of each shift to
ensure they are in the proper working order.
4. In the event of an emergency, activate the emergency stop pushbutton immediately. Then
turned the power “off” from the main power source of the equipment.
5. The power switch should be turned “off” after use and should never left the power “on”
when the unit is unattended.
6. Do not use the same RF channel and ID code as any other unit in use at the same facility.
7. Ensure the wrist strap is worn at all time during operation to avoid accidental dropping.
8. Never operate a crane or equipment with two (2) transmitter units at the same time with
same RF channel and ID code.

RECEIVER INSTALLATION
8.1 Preparation For Installation
1. Required Tools:
(1) Flat Head Screwdriver (-)
(2) Phillips Head Screwdriver (+)
(3) Multi-Meter
(4) 14mm Wrench x 2
(5) 10.5mm Drill -Bit
2. Ensure receiver is not set to the same channel and ID code as any other units in
operation at the same facility.
3. Prior to installation, make sure the equipment itself is working properly.
4. Use the multi-meter to check the voltage source available and ensure receiver voltage
setting is correct for this voltage.
5. Prior to installation, switch “off” the main power source to the equipment.
8.2 Step By Step Installation
1. The location selected should have the antenna visible from all areas where the
transmitter is to be used.
2. The location selected should not be exposed to high levels of electrical noise.
3. Ensure the selected location has adequate space to accommodate the receiver
enclosure.
4. Make sure the receiver unit is in upright position (vertical).
5. The distance between the antenna and the control panel should be as far apart as
possible (see diagram next page).
6. Drill a hole on the control panel (10.5mm)
7. Tightened the two bolt nuts provided.
8. If the control panel has a plastic surface, extended grounding wire should be used.
9. For system wiring, please refer to the output contact diagram on page 12~14 or on the
receiver enclosure.
10. Ensure all wiring is correct and safely secured and all screws are fastened.
17
Page 18
8.3 System Testing
1. Connect the power source to the receiver and test the operation of each function to
ensure it operates in the same manner as the pendant controller.
2. Ensure the receiver MAIN can be properly controlled by the remote control.
3. Ensure the limit switches on the equipment that limit all travels are working properly.
4. Ensure the pendant controller is located in a safe location where it would not interfere
with remote operation.

TRANSMITTER OPERATION
1. Make sure the (2) alkaline batteries are installed correctly. Do make sure to use alkaline
type batteries for longer operating time between battery replacements.
2. Turn “on” the power switch located on the top left hand corner of the transmitter unit (see
diagram next page). Immediately after turning “on” the transmitter unit, the status LED
indicator located at the center of the power switch will display a green light for up to 1.5
seconds, do make sure that the red EMS pushbutton is in its elevated position.
If the status LED displays a red blinking light (ON 0.1 second and OFF 2.0 seconds)
or no light at all, then you must replace a set of new batteries before operation. If the red
blinking light is ON 2.0 seconds and OFF 0.1 second, the transmitter unit will
deactivates itself (locked) due to a jammed or defected pushbutton contact. This important
safety feature is designed to prevent unexpected crane movement at system start up caused
by a defected pushbutton contact.
After transmitter self-diagnosing procedure is completed without any problems detected
(within 1 second), all transmitter key functions and the receiver MAIN will be activated.
3. Alpha 540T/560T model When the transmitter unit is turned “on” to begin work, the
LED-I will light up to indicate only the main hoist and/or trolley is activated. If you want to
activate the auxiliary hoist and/or trolley, press the "Select" pushbutton, and the LED
display will now switched from LED-I to LED-II to indicate that only the auxiliary hoist
and/or trolley is activated. Press "Select" again to have both main and auxiliary hoist
and/or trolley activated at the same time (both LED-I and LED -II lit). To switch back to the
main hoist and/or trolley activation, just press the "Select" pushbutton once again. (please
refer to section 3.3 on page 6)
Every time when the transmitter unit is turned “off” and then “on” again, the "Select "
setting will resets itself to LED-I (back to main hoist and/or trolley active)
4. Alpha 540T/560T model "Select" setting can not be changed while other command
pushbuttons are in use (command pushbuttons pressed). To insure maximum safety,
"select" settings (I, II, I&II) can only be changed when all command pushbuttons are in
their neutral position (command pushbuttons not pressed).
19
Page 20
5. In case of an emergency, press down the red EMS pushbutton will immediately deactivates
the receiver MAIN. When the EMS pushbutton is activated, the status LED on the
transmitter unit will display a red blinking light to indicate EMS activation (ON 0.5
second and OFF 0.5 second). To reactivate the system again, turn the EMS pushbutton
clockwise so that the red cap will elevate to its non-active position. Then turn the
transmitter power switch “off” and then “on” again to activate all transmitte r key functions
and the receiver MAIN. As for the Alpha 540T and 560T models, to reactivate the system
after EMS reset, just press any command pushbutton (please refer to JP1 setting on page 15
and 16).
6. Please note that conflicted movements are inte rlocked to one another for safety purpose.
Pressing conflicted commands at the same time will result in a non-transmission.
