1 GENERAL INFORMATION
The Hirschmann ECS PRS 80 System has been designed to provide indication from a various types of
radio sensors. To simplify operation, this PRS 80 console set up for wind speed only, but can be
software upgraded to indication other various types of radio sensors, i.e. A2B, Load, and Angle.
System limits can be set by the user; when these limits are exceeded the system will warn the
operator by sounding an audible alarm, flashing the backlit LCD and de-energize the lockout relay.
A system relay can be connected to the cranes lockout system to provide a lock out when exceeding
any of the user limits. The defining the lock out connections are the responsibly of the crane owner.
2 WARNINGS
The Hirschmann ECS PRS 80 System is an operational aid, which warns a crane operator of
approaching two-block conditions, which could cause damage to equipment and personal injury.
This device is not, and must not be a substitute for good, sound operator judgment, experience and
use of accepted safe crane operating procedures.
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 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 to answer thoroughly and correctly all questions asked
during 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.

4 SYSTEM DESCRIPTION
4.1 Operating Console
The console has 2 functions:
•Accepts inputs from the crane operator (limits and setup)
•Displays important data and information from the sensors
The operator’s console should be mounted in the operator’s field of vision.
4.1.1 Liquid Crystal Display
The Liquid Crystal Display (LCD) used in the Hirschmann ECS PRS 80 console is a wide temperature-
range graphic display with transflective characteristics that give it a high visibility in sunlight and during
backlit night operation. Due to the nature of any LCD, it works on the principle of polarization of light. It
should be noted that dual polarizations that are at a certain angle to each other can reduce the
amount of light up to completely eliminating it if that angle becomes perpendicular. This can have
significance if the operator is wearing polarized sunglasses that happen to be perpendicularly
polarized in relation to the LCD’s polarization. In this rare case, the operator has to work without
sunglasses or find different sunglasses that do not have this characteristic, in order to avoid having the
visibility of the display impaired.
The LCD contains an automatic temperature compensation that will adjust the LCD’s contrast
according to the surrounding temperature.

the control lever lockout system can result in harm to the crane and danger to property
and persons.
•Never use the by-pass function to either overload or operate the crane in a non-
permissible range.
5 SYSTEM OPERATION
When switching on crane ignition switch, the system starts with an automatic test of the system, of
lamps and audible alarm. During the test, the LC display shows the console and system software
version. After the testing is complete, the main operating screen will be displayed.
If the wind speed requires setup (installed), refer to the Installation and Setup Section 6.3 sensors
procedure allows the operator to input the sensors being used and the limits for the sensors. The
operator must complete the setup procedure for each sensor.
The speed can be shown in miles per hour, or kilometers per hour.
The % of limit is shown at the bottom.
The peak will be the highest wind speed recorded since the system was started. When the system is
turned off the peak value will be reset. The peak value can also be reset by pressing the
button.

6.4 Wind Speed Sensor
The sensor is delivered with a bracket support that allows the sensor to stay perpendicular to the
ground through the boom angle range.
CONTACT CRANE MANUFACTURER FOR WELDING INSTRUCTIONS PRIOR TO WELDING
ON BOOM.
The mounting pole is affixed to the boom tip at your discretion so that the anemometer sensor is
mounted approximately a foot higher than the boom sheaves and will not interfere or be damaged by
hoist lines or extension mounting or movement. Affix the mounting pole to the boom tip or possibly the
length cable anchor pin so the pipe supports the sensor. It must be installed so that no part of the
crane can disrupt the measurement of wind.

The only time you should need to open the console is when there is power to the console and the
display is blank. If you find it necessary to open the console, inspect the gasket for damages and
replace it if necessary, refer to Section 7.4 Troubleshooting Moisture.
With power to the console you should see the following:
If the LED’s, are not working, replace the console. Note: the 2A fuse protects output relay in case
current over draw. The board is protected by a 0.5A resettable fuse.
7.4 Troubleshooting Moisture
The receiver contains electronic components and has an IP65 protection rating. These electronic
components cannot be designed to withstand exposure to moisture over a longer period of time. If you
find water or moisture inside any of the housings, the source for the water ingress has to be detected
and corrected to ensure proper operation.
There are two major possibilities for the occurrence of excessive moisture inside an enclosure:
1) Water ingress; caused by a cracked or broken housing or lid, or a defective gasket.
2) Condensation
This outline gives instructions for detecting the cause for excessive moisture by using simple
troubleshooting methods and how to prevent the moisture ingress from happening again.
