Warning
Improper installation of program and duty chips will damage
them. The correct way to install these chips is to align the
notch on the socket and the notch on the chip at the same
end. This must be done with the power to the system "OFF."

SYSTEM REMOVAL AND INSTALLATION
UPGRADING OLDER GREER SYSTEMS (LA-1250, LAR-1200, BA-1500, & LOHD-1100)
EXTENSION REEL
1. REMOVE THE COVER ON THE EXISTING EXTENSION REEL.
2. CLAMP THE CABLE FROM THE SENSOR TO THE TRIANGLE PLATE USING CABLE CLAMPS. ENSURE THAT
THE CABLE FROM THE ANGLE SENSOR DOES NOT INTERFERE WITH THE EXTENSION REEL CABLE OR
WITH THE EXTENSION REEL ITSELF.
ANTI TWO-BLOCK CIRCUIT
For MicroGuard®424 System installations, the anti Two-Block circuit must be isolated. Two terminal strips
require this modification. One strip is located on the triangle plate and the other is on the extension reel.
TO ISOLATE THE CIRCUIT:
1. STARTING WITH THE TRIANGLE PLATE TERMINAL STRIP, MOVE THE TOP BROWN WIRE TO TERMINAL #5
AND THE TOP BLACK WIRE FROM THE MOUNTING SCREWS TO TERMINAL #6.
2. ON THE SPOOL TERMINAL BLOCK, REMOVE THE 2 CENTER SCREWS. REPLACE THEM WITH THE #4-
40X¼” SCREWS AND SECURE THE WIRES TO THE TERMINAL ACCORDING TO APPENDIX A.
NOTE: USE A CABLE CLAMP AND ONE OF THE EXISTING SCREWS ON THE EXTENSION REEL COVER
TO HOLD THE EXCESS CABLE. THIS WILL PREVENT THE CABLE FROM GETTING CAUGHT
ON THE REEL.

DISPLAY
Mount the display in the cab where it can be easily observed without obstructing the view through the cab
window. Position the display cable so that it will not hinder the normal operation of the levers and controls of
the crane.
COMPUTER
Mount the computer inside or outside of the cab with the cable glands facing down. Ensure that there is
enough cable line from the other sensors. Note: The cable to the pressure transducers cannot be
increased by splicing in additional cable.
PRESSURE TRANSDUCERS
Do not remove the existing transducers in the hydraulic system unless a failure occurs. If the transducers are
confirmed to have failed, then replace them accordingly. On upgrades from the RLI-200, it will be necessary
to remove the connectors from the computer end of the cable. Do this, but cut the cable as close to the
connector as possible. This will give you as much cable length as possible.
EXTENSION REEL CABLE TO COMPUTER
Connect the cable to the extension reel. Route the cable to avoid cable damage, i.e., cutting or pinching
during the normal movement of the boom.
When upgrading the existing extension reel with a new angle sensor and connector, use the following table
for wiring at the extension reel terminal block. Use Appendices A-D for reference. Use Cable A047013 from
extension reel to computer.

ANGLE SENSOR
See Appendix A for installing the Angle Sensor to existing extension reel. Route the cable to the terminal
block, clamping the cable along the top of the triangle plate. Use ¼ -20 nuts to mount the angle sensor to the
existing studs in the extension reel.
BULKHEAD CONNECTOR
Appendix D illustrates the supplied bulkhead connector to replace the existing connector. It also has terminal
connections. Use in conjunction with the table shown above. Appendix B shows how the Extension and
Angle sensor as well as the Anti Two Block signal is connected to the terminal block with the bulkhead
connector.
A047013 CABLE
Appendix C is for cable A047013. This cable connects the extension reel to the computer. Use
Appendix C in conjunction with the Cable 3 wiring table on page 11.

MEASUREMENTS CRITICAL TO CALIBRATION
The dimensions illustrated in the following two pages are vital to the calibration procedure. These
measurements should be obtained during the installation of the components and must be entered into the
System after initializing Personality and before starting sensor calibration. Follow the instructions for each
dimension required. Then, record each dimension on the appropriate page. Double-check the measurements
obtained to ensure accuracy.

MAIN BOOM DATA
MicroGuard-414 allows for up to four main boom calibrations.
Any configuration of the telescoping boom, which is not detachable and will alter the operating length and/or
moment, will require a separate calibration. This will include: Booms with more than one telescoping
sequence or boom + manual or powered telescoping tip extension.
Detachable attachments such as lattice fly's, telescoping fly's and auxiliary heads do not require calibration
and are covered later in this document.
