DESCRIPTION
RX-MFS-ESCAN-HS1A is an MFS 2.4GHz receiver with 2 CAN Interfaces, 2 independent E-
Stop Relay Outputs, 2 Application Relay Outputs, 4 optional 0~10V, 0~20mA analog or 0~30V
digital inputs, a USB and an optional RS232 interface. It shall be equipped with RTC and SD
card for data logging capability. It is designed for applications using CAN bus topology to
integrate a number of devices and operating on 12 or 24V battery.
The function of this device is to provide a bidirectional RF control to CAN bridge in a machine
control application, along with standard Main Contact safety functionality. Receiver and CAN
settings shall be H-Link configurable and are saved to an on-board EEPROM.
RX-MFS-ESCAN-HS1A uses the MFS 2.4GHz communication protocol. The decoder receives
control packets at a 1%-10% duty cycle to the receiver and transmits one feedback packet for
every control packet. The feedback packets are sent on one of the sixteen IEEE 802.15.4 ISM-
band channels, ranging from 2.405-2.480GHz. The channels and duty cycle are configured with
the H-Link software. The packets are DSSS O-QPSK modulated using an on-board surface-
mount transceiver and then amplified through an on-board surface-mount bi-directional RF Front
End. The RF signal goes through a surface-mounted SMA connector, through a 50-ohm coaxial
cable to an external antenna for transmission/reception. The external antenna is a Hetronic
Gainflex 2.4GHz antenna (Hetronic Part Number 56506605) with a nominal gain of 3dB.
•The antenna is Model: 56506605 – Manufacturer: APEX - Gainflex Type GK 442TF R
Half wave flexible dipole – maximum power 10W – TNC Plug Reverse Polarity
•Antenna Gain: 3 dB

FUNCTIONAL DESCRIPTION
Operation
As a standard Hetronic MFS receiver, this module is equipped with 2 microcontrollers, Main and
Stop, for safety and redundant control of E-Stop Relay outputs. The Stop controller is common to
standard 2.4GHz MFS receivers. The Main controller will have full control of RF, analog inputs,
digital outputs, USB, RS232 and CAN interfaces.
There are 2 CAN interfaces, namely CAN1 and CAN2, with optional isolated supplies, RS232
interface with a 4-pin Dubox header and a USB interface that can be used for firmware update and
H-Link configurations.
CAN2 will be dedicated to J1939 protocol for possibility of controlling and monitoring other devices
on the truck using J1939 protocol. CAN1 will be used as a CAN Master on CAN open protocol to
control and monitor other Hetronic Slave devices.
RTC with a back-up battery shall be used to keep time for data logging of different possible events
such as abnormal conditions and operating times.
Nominal operating voltage range will be 9 to 24Vdc. Electronic control unit will remain operational
within 6 to 36Vdc.
SYSTEM OVERVIEW
Theory of Operation
The Hetronic radio remote control system includes a transmitter and receiver. The transmitter
electronically generates a carrier frequency
which allows it to communicate with the receiver. Each system is programmed with a unique address
code. This code allows the operation
of multiple systems in the same general vicinity. The receiver only accepts commands from the
transmitter with the same address code.
NOTE: The receiver and transmitter have the address code set at the factory.
E-Stop Function
The most important features of the radio remote control system is the E-Stop. The transmitter sends
the E-stop status signal along with the specified crane/machine function. This method confirms that
ongoing operations are safe. If the E-stop pushbutton is pressed, the relay module in the receiver
causes all crane/machine motions to stop. The receiver goes into Safe mode. To restart the system,
disengage the E-stop button and press the Start/Horn button. The E-Stop responds faster than any
other function. When E-Stop is engaged, the system ignores any other signal that is
transmitted.
The problem must be corrected before the system will respond to any other signal. The E-Stop is
self-monitoring and redundant in the transmitter
and receiver. The system performs a self-test to ensure the E-Stop circuit is working properly. If an
error is detected, the system automatically
goes into Safe mode. When the transmitter is turned on, it performs a self-test to be sure that
communications are within designated parameters.
If an error is detected, the transmitter will not transmit any signals.

Receiver Safe Mode
The following conditions cause the receiver to go into its Safe mode:
• The transmitter goes into Sleep Mode
• Radio signal interference
• Transmitter out of operating range
• E-Stop button is activated
• E-Stop circuit failure
• Low battery sends E-stop after time out
When the transmitter signal is no longer sensed by the receiver, the Time Out process begins.
The Time Out period is set to
450 msec at the factory. If the receiver does not establish contact with the transmitter within that
time period, it goes into the
Safe Mode. In Safe Mode, the receiver shuts off power to the output modules and activates the
E-stop function. To restart the
system, be sure the transmitter signal is active and sensed by the receiver. Then press the
Start/Horn pushbutton.
Installation
Pre-Installation Precautions
1. Make sure the transmitter and receiver have identical ADMO numbers and
channels.
2. Make sure the receiver is not set to the same channel as any other systems in
use in the surrounding area.
3. Make sure that the controller or equipment is working properly prior to radio
remote control installation.
4. Make sure the power source to the receiver is set correctly.
5. Switch off the main power source to the controller or equipment prior to
installation.

Step-By-Step Installation
1. For the Radio Remote Control to operate smoothly, the receiver should be installed
in such a position as to allow the maximum reception of radio waves from the antenna.
Thus, for best reception the location of the receiver should be such that it is visible to
the operator at all times.
2. The location selection should not be exposed to high levels of electric noise and
should not be surrounded by metal or other conductive materials. Mounting the receiver
next to an unshielded variable frequency device may cause interference. The metallic
parts of the machine to be controlled that surround the receiver create a barrier that
interferes with reception of the transmitter signal. Always locate the receiver as far away
from variable frequency drives as possible. Sometimes, however, in extreme cases and
if the space is inadequate, installation needs to be carried out inside the electrical
boards or in areas of the machine that are not ideal for good radio reception. Should this
kind of installation be necessary, then the equipment must be provided with an
additional antenna using an extension to be placed on the outside. Your dealer will be
able to provide further detailed information regarding the most appropriate items specific
to the application.
3. Ensure the selected location has adequate space to accommodate the receiver.
Always locate the receiver so as to avoid the possibility of damaging the antenna. In
most cases, the receiver can be housed on any side of the machine or, if necessary, for
installations on vehicles even inside the glass cabin. It is also necessary to place the
receiver where it is accessible and safe to work both for those who carry out the
installation of the electrical connections and for those who will carry out future
maintenance.
4. Depending on the application, the receiver should possibly be installed in such a
manner that any connectors or cable plug holes face downwards. Consult with a
Hetronic expert for best antenna mounting orientation on your application

5. Should such an installation be performed on board mobile machinery or on a vehicle, then
you should attach four rubber bumpers that can be ordered directly from your Hetronic dealer,
unless already supplied as standard fittings on the radio control type in use. These rubber
bumpers will dampen the strong vibrations coming from the machine from reaching the
receiver.
6. Determine the position where the enclosure is to be mounted and drill the holes as per
diagram below.

Troubleshooting
If your ES-CAN HL receiver does not operate as required, follow the recommended
troubleshooting sequence to help isolate the cause and determine corrective action.
If you need more information, contact your nearest Hetronic dealer.
