1 GENERAL INFORMATION
The PAT TRS 05 system interface has been designed to use radio communication for load sensors.
The TRS 05 receives a radio signal from a transmitter sensor and converts a signal as a replacement
for the existing hardwired sensor.
Review system operator’s manual for system description and operation. All system functions and error
codes will remain the same for the DS350 system.
This manual will describe the operation, sensors setup and calibration, and additional troubleshooting
points for the TRS 05.
2 WARNINGS
Review system operator’s manual for system warnings.
The responsibility for the safe operation of the crane remains with the crane operator who must ensure
that all warnings and instructions supplied are fully understood and observed.
Prior to operating the crane, the operator must carefully and thoroughly read and understand the
information in this manual and the system manual to ensure that the operation and limitations of the
system and the crane are known.
The system can only work correctly, if all sensors/transmitters have been properly set. For
correct setup, the operator has correctly complete all procedures in this manual, the system
manual, and the setup procedure in accordance with the real rigging state of the crane. To
prevent material damage and serious or even fatal accidents, the correct adjustment of the
system has to be ensured before starting the crane operation.
Always refer to operational instructions and load charts provided by the crane manufacturer
for specific crane operation and load limits.

Heartbeat LED: When blinking, this small surface board mounted green LED indicates the system is
operation properly.
ID button: The red ID button, located below the software chip on the receiver board, is used to setup
the sensor transmitter to the receiver.
5 OPERATION
5.1 RECEIVER
Upon switching on crane ignition switch, the system starts with an automatic test of the receiver board,
LEDs and electronic components. The red power LED should be on and the green LEDs that sensors
have been linked to should also be on.
If an alarm condition exists investigate and clear the condition before operation and using the system.
During the normal operation of the system, the POWER and SENSOR ON LINE (if linked to a sensor)
LEDs should be on.
POWER LED
The POWER LED shows that the receiver is getting power from the crane. The receiver is on any time
the crane is operating and supplying power to the system.
SENSOR ON LINE LED
The SENSOR ON LINE LED indicates the status of communication of the transmitter(s). During
normal operation of the system, the LED will be on. The LED will flash if communication or
transmission between the sensor transmitter and the receiver is interrupted or lost. The system should
not be operated if the SENSOR ON LINE LED is flashing. If the LED is off no sensor is linked to this
channel.
LOW BATTERY LED
The low battery indicator will light indicating that you have a limited time to operate before the sensor
battery life ends. When the battery level is to the point that it is too low to operate, the system will stop
functioning. Use any off-the-shelf alkaline C-cells; Duracell, Eveready, etc.
ALARM LED
This LED will light simultaneously with the engaging of the lock out solenoids (if installed).
Test the electronics
Cycle the power to the system, each LED on the receiver will light for 2 seconds when the system is
powered. All of the indicator lights must come on or the system is not functioning properly. If any light
does not function, do not use the system until it has been repaired.
Refer to receiver operating manual for pre-operational inspection.
If a green sensor on line LED starts to flash, this means a sensor is installed and the communication
link has been lost. When communication has been lost to a load cell, the receiver will output the
maximum voltage signal for the output sensor (9VDC).
If a low battery LED is on, replace the batteries in the linked transmitter, refer to Battery Replacement.
The TRS 05 setup/calibration procedure allows the operator to input the type of sensors being used,
and adjust the zero point and output adjustment of a load sensor. The operator must complete the
setup procedure for each sensor.

5.2 TRANSMITTER
The transmitter has an LED that will flash when a signal is transmitted to the receiver. Our system
transmits an OK signal every two seconds via three separate channels. This is to ensure accurate and
consistent reception of data and to reduce the possibility of unnoticed failure. The separate channels
greatly reduce the probability of failure due to external interferences. The receiver cycles through the
three channels, when software logic and/or lost signal, system will indicate a communication error.
5.2.1 Load Cell
The load cell transmits once every 1 to 2 seconds when in standby, and 2 times a second when the
load changes. It will continue at 2 times a second for less than a 1 minute before dropping back to one
transmission every 1 to 2 seconds. There is no time it goes to sleep.
Note: To extend battery life, remove batteries from transmitter(s) if load cell(s) will not be used for
extended periods of time. Reinstalling batteries into the transmitter will not require a set up.
NOTE: If the load cell is installed or reinstalled it will require
5.2.2 Two-block Switch
The PAT radio Anti-two Block (A2B) system works to prevent a two block condition using a weight and
switch. During normal operation the weight closes the A2B switch. The transmitter has an LED that
flashes approximately every 2 seconds when the switch is transmitting. If the weight is lifted and the
switch opens, the transmitter immediately (<100milliseconds) sends a two-block signal condition to the
receiver to be displayed on the console and lockout the crane movements (if connected to solenoid).
The LED will flash rapidly during a two-block condition and will stop flashing after 15 seconds when
the switch goes into sleep mode. While in sleep mode, the receiver will stay in a two-block or
communication loss condition. Sleep mode increases battery life by reducing the number of radio
transmissions. To wake the switch, simply close the switch by lowering the weight.
5.3 REPEATER
The purpose of the repeater is to reduce the possibility of a communication loss error by receiving the
load cell transmitted ID code and re-transmitting the same ID code out to the TRS 05. To do this, the
repeater is positioned at the boom tip, up the hoist rope from the load cell and up the boom from the
TRS 05. If the load cell does not have a direct line of sight or blocked by a wall/structure from the TRS
05 then there is less chance of the signal absorption/interference.
The repeater is setup from the factory to repeat signals from the load cells to the TRS 05 receiver.
TRS 05 can receive both transmissions (load cell and repeater) and output the load signal to the
system computer.
After switching power on to the repeater from the crane ignition switch, the system starts with an
automatic test of the repeater board, LEDs, and electronic components. The red power LED should be
on and other red LED blinks when the repeater is transmitting a signal.

6.2 REPEATER
The repeater module is mounted on the boom tip in line of sight to the receiver and the load cell. The
main purpose of the repeater is to receive and transmit the load cell ID code of the load cell during
operation. If the load cell line of sight is obstructed by a barrier (i.e. wall or building), the repeater
should prevent and signal loss.
Power cable connections: PIN 1 - +UB (9 to 30VDC), PIN 2 - GND
6.3 CENTRAL UNIT INSTALLATION
The power supply will be from 10- 30 volt DC. The signal output of the TRS 05 is dependent on the
placement of red bridges installed on the channel jumpers: 1 (for signal #1), 2 (signal #2), 3(signal #3),
and 4(signal #4). Each jumper has 4 bridge positions as follows:
1-2 voltage output 0..5V (required for the standard DS350 system)
3-4 amperage output 4..20mA (required for the modular DS350 system)
5-6 digital output
7-8 A2B switch output

Remove the battery covers from the sensors to be installed.
Main load cell - channel 1; Press and hold the ID button for 3-6 seconds until the 1st green LED’s will
begin blinking and release the ID button. The receiver begins to search for a transmitter ID code. On
the load sensor/transmitter, remove the card from the batteries or remove two batteries for 10 seconds
and replace them. In less than 10 seconds, the 1st green LED will become solid when the transmitter is
linked.
Auxiliary load cell - channel 2; Press and hold the ID button for 6-9 seconds until the 2nd green
LED’s will begin blinking and release the ID button. The receiver begins to search for a transmitter ID
code. On the load sensor/transmitter, remove the card from the batteries or remove two batteries for
10 seconds and replace them. In less than 10 seconds, the 2nd green LED will become solid when the
transmitter is linked.
Main A2B switch - channel 3 (If included as system option); Press and hold the ID button for 9-12
seconds until the 3rd green LED’s will begin blinking and release the ID button. The receiver begins to
search for a transmitter ID code. On the A2B switch/transmitter, remove the card from the batteries or
remove two batteries for 10 seconds and replace them. In less than 10 seconds, the 3rd green LED will
become solid when the transmitter is linked.
Auxiliary A2B switch - channel 4 (If included as system option); Press and hold the ID button for
12-15 seconds until the 4th green LED’s will begin blinking and release the ID button. The receiver
begins to search for a transmitter ID code. On the A2B switch/transmitter, remove the card from the
batteries or remove two batteries for 10 seconds and replace them. In less than 10 seconds, the 4th

8 LOAD CELL INSTALLATION
NOTE: After installation the load cell will need to be zeroed with no force applied and adjusted
to a permissible heavy load.
The load cell and plates are installed at the dead end of the wire rope that is being used to lift the load.
The appropriate pins (length and diameter) for the type and size of socket, block, or ball must be used.
Ensure that the correct pin used is rated for the maximum line pull capacity and the side load plates
will be straight when attaching the dead end lug and the load cell. Install the side plates using the 2-
1/4” pin so the pin head is on the antenna side. Ensure all safety pins are installed properly with
washers and bushing to fit the hole diameter and pin length.
9 LOAD SENSOR CALIBRATION
While the ID button is held or in the calibration process, the sensor outputs will not correctly indicate
the status of other installed sensors. Correct operation will return when the menu is exited or
calibration process is complete or system is powered off/on.
The load cell must be calibrated to ensure accuracy. The load sensor calibration is completed
complete the following steps:
1. Installing the load cell sensor (refer to 7.1 Install Sensor, if not complete)
2. Zero the load cell. The zero point adjustment will have an even affect across the entire range
(for example, 200 lb at both low and high loads).
3. Adjust the gain to a 70% permissible load. The gain adjustment will have only a small effect on
light loads, but a large effect on heavy loads.
Note: If an incorrect menu is activated or the button is released accidentally, simply cycle the power
and start over.
Note: When the system is in calibration mode, the RCL system NOT in operation; therefore, crane
operating guide line and load charts must be followed during calibration mode or other crane
operations.
NOTE: The unit will remain in main or auxiliary calibration mode until power is cycled off/on. After
completing the main load cell calibration, cycle power off/on and complete the auxiliary load
calibration.
Main load cell calibration: Press and hold the ID button for 43-46 seconds until the 1st yellow and
green LED’s will begin blinking and release the ID button. The 1st yellow and green LED will become
solid, showing the receiver is now in calibration mode for the main load cell on channel 1. Complete
sensor zero and gain adjustments in this section.
Auxiliary load cell calibration: Press and hold the ID button for 46-49 seconds until the 2nd yellow
and green LED’s will begin blinking and release the ID button. The 2nd yellow and green LED will
become solid, showing the receiver is now in calibration mode for the auxiliary load cell on channel 1.
Complete sensor zero and gain adjustments in this section.
