Lodar Remote Control Help and Support
How do I install a Lodar Remote Control Aerial?
ELP have created a video and guide to help you install the aerial and cable into the Lodar receiver.
Please follow this link: Lodar Aerial Installation
How do you program a Lodar remote control transmitter?
Depending on the model number Lodar transmitters have different ways of programming them to the receiver.
Please follow this link: Programming a Lodar Transmitter Remote Control
Do Lodar remotes have any fault diagnosis?
Only Lodar wireless remote control receivers with a Blue seal inside their lids have fault diagnosis so please follow this link: Lodar TI Chipset Fault Codes
For a red seal lid please contact us.
The majority of the faults that we encounter are caused by a poor earth path from the Lodar receiver to the battery, so we recommend starting your fault diagnosis here. If you need help, please contact us.
How do you change the programming on the Lodar Transmitter holder AC9813?
To change the beeping type and volume as indicated on the circuit board on the item we have created a video, please follow this link: Lodar Transmitter Holder AC9813 LoCator Programming
You can buy them here: Holder for the Waterproof IP Transmitter with LED and Buzzer – AC9813
What Lodar products are retired or obsolete?
We have archived these products in our website for reference and to provide replacement alternative parts, please follow this link: Retired Lodar Parts
What frequency do Lodar use for their remote controls?
Lodar use a variety of frequencies, with options of 418 MHz or 434MHz, and multiple variations which means you have to buy the correct replacement parts.
To learn all about the different Lodar frequencies please follow this link: Lodar Wireless Remote Control Frequencies
ELP Engineering Help and Support
Can you use a Lodar remote control for proportional controlling a hydraulic valve?
Yes we can control proportional hydraulic valve blocks with a Lodar which uses variable current to operate the Pulse Width Modulated ( PWM) output.
To read all about it please follow this link: Lodar Proportional Remote Controls
Do you have any Lodar wiring diagrams?
Lodar Documentation including wiring instructions, specifications and data (- this takes you to the Lodar website)
ELP Engineering FAQ’s
Are you available for support outside of office hours?
Yes. Please call the office as our phones are redirected to the support team outside of office hours.
What’s the difference between “Splashproof” and “Waterproof ” transmitters?
By Splashproof, we mean that an item is protected from low pressure water jets (rain) from any direction and is protected from limited dust ingress; this is known as IP55 (IP is Ingress Protection).
The original Lodar transmitters are splashproof and they have been used on recovery trucks for years.
Those items described as waterproof are protected from immersion in water up to 1 metre deep and also protected from total dust immersion; this is known as IP67.
The waterproof transmitters allow you to wash them, so are ideal for dirty environments such as cattle foot trimming and agriculture.
What is a radio remote control system?
It consists of a hand held transmitter and a machine or building mounted receiver which communicate using government approved radio frequencies.
If I have a winch, for example, will the transmitter work other winches when we are all together?
Not the units we sell. The transmitter and receiver are paired to each other using software for safety. We are aware that low cost units do not have this feature and hence we do not sell them.
If I break my transmitter, can I buy one on its own or do I have to buy a new radio remote control system?
You can buy a replacement transmitter in the event of it being damaged, and, if it is a Lodar unit, you will receive instructions on how to pair it with your receiver. If it is a Hetronic unit, it will need the ADMOS unit programming by ourselves.
What if my radio remote control system doesn’t work?
Both Lodar and Hetronic systems show their status of operation, so you can quickly and easily determine what is at fault. All ELP Engineering Ltd and Lodar products are covered by an exceptional 5-year pro-rated warranty.
Where are you based?
We’re based near Uttoxeter, Staffordshire which is the home of JCB and near Alton Towers, so we can easily access any part of the UK to provide on-site support if required.
What can the radio remote control systems operate?
The radio remote control systems we distribute are capable of turning on and off 12volt DC, 24volt DC, and 240 volt AC. The systems can also provide proportional control known as PWM for 12volt DC and 24volt DC.
What is PWM (Pulse Width Modulation) or proportional control of hydraulic valve blocks?
The proportional control is the ability to open a hydraulic valve like a tap, opening the tap gently up to the desired flow from the valve. The control is carried out using PWM, and the radio remote control systems are configured by us to provide you with the desired machine control. This means that we can replace a manual lever valve block with a radio remote control system and give the same feel of control to the operator.
Can you configure the PWM proportional radio remote control to give the right operator feel?
Yes, each unit is programmed to suit the hydraulic valve block it controls and your requirements. The units can be programmed to provide different flows for each individual spool valve, so you can have different speeds set for each output which is especially useful when complying to a British standard or international standard (e.g., BS EN 280 for mobile elevating work platforms), for design calculations, stability criteria, examinations and tests.
I don’t know about hydraulics or electronics but I want to radio remote control a machine – can you help?
Yes we can. We’re here to ‘hELP’. The director is a qualified engineer who has designed and operated machines for years. The experience gained over the years means that all you need to do is answer a few questions and we can do the rest. We can supply part of, or an entire system, which we can commission and install as well if you wish.
Are the radio remote control hydraulic systems safe?
Yes, the systems which we specify include built in safety systems which, in the event of a sticking valve, for example, allow the user to instantly turn off the system. Emergency stop buttons are provided where required and hence the system is safe.
What do you put into the radio remote control system to make it safe?
To make it safe there are multiple options available. Both the Lodar and Hetronic receivers have dedicated outputs for safety circuits.
What happens when the electric winch solenoid sticks on my winch and I cannot stop it?
We use the safety output from the receiver to activate an Albright battery isolator, turning off the unit using the radio remote control hand held transmitter will isolate the battery instantly.
What happens when the hydraulic valve sticks or someone moves the manual lever on the hydraulic valve block and the radio remote control operator doesn’t want it to move?
We only specify and sell ‘fail safe’ hydraulic valve blocks which do not allow hydraulic oil to flow into the valve block until the operator uses the radio remote control system. The hydraulic oil flows directly back to tank when the radio remote control system is not in use. This function is carried out with a hydraulic valve known as either a hydraulic safety valve, unloader or a hydraulic dump valve.
Do you supply hydraulic dump valves?
We can supply a hydraulic dump valve and they are relatively inexpensive. However, it is better to integrate the dump valve into a valve block to be more cost effective and to reduce the leak paths.
Do you supply hydraulic flow control valves?
Yes and they are made in the UK. The flow control valves we supply are ‘fail safe’ so they are also act as a dump valve when the radio remote control system is not being activated.
What is the cost of a radio remote control system?
Please contact us if you need help specifying your requirements.
What not to do….
Do not put a switch in between the lodar receiver and the output it operates. When the switch breaks the flow of current the receiver will sense it and turn off the Lodar receiver. Please talk to use and we can provide a Lodar receiver with inputs for the switches and logic to turn off the output / outputs
Do not install a remotely mounted aerial using the small nut on the cable into a steel plate, it will corrode and ‘rust’, please use the supplied 20mm cable gland and use the fitting instructions / video above.
