INSTALLATION MANUAL

GS112 Length Sensor Cable Reel Installation Manual

1.1 GS112 InstallationThe GS112 includes the LS112 cable reel and the GS012 angle/length sensor. Following cable reel installation and boom length indication calibration, boom angle indication will have to be verified and possibly calibrated. Refer to the Angle Calibration Procedure № 2: Correct with the GS550/GS820 section of the standard user manual (GS550 Manual sec. 2.4c, GS820 Manual sec. 2.3c).

1.1a Maximum Boom ExtensionConfirm the maximum extension of the GS112 cable reel is compatible with the maximum boom extension.

Cable reel used to measure the total length of the boom (measuring rope attached to the boom tip):Step 1. Note the maximum cable reel extension: 140 ft.

(42.6 m). T = ___________________Step 2. Note the length of the boom fully retracted, from

the boom pivot to the center of the head sheave. A = ___________________Step 3. Note the length of the boom fully extended, (do

not include the length of a lattice extension or jib). B = ___________________Step 4. Calculate the maximum boom extension. C = B – A = ___________________Step 5. Compare the maximum cable reel extension (T)

to the maximum boom extension (C). D = T – C = ___________________

The maximum cable reel extension must be greater than the maximum boom extension (D>0).

Cable reel used to measure the boom length in a proportional mode (measuring rope attached to the end of the first telescoping section): Step 1. Note the maximum cable reel extension: 140 ft.

42.6 m). T = ___________________Step 2. Note the length of the boom from the boom pivot

to the end of the first telescoping section with the boom fully retracted.

A = ___________________Step 3. Note the length of the boom to the end of the first

telescoping section with the boom fully extended. B = ___________________Step 4. Calculate the maximum extension of the first

telescoping section. C = B – A = ___________________Step 5. Compare the maximum cable reel extension (T)

to the maximum extension of the first telescoping section (C).

D = T – C = ___________________

The maximum cable reel extension must be greater than the maximum extension of the first telescoping section (D>0).

WARNING! Do not use the cable reel boom length sensor in proportional mode unless

the boom is mechanically limited to proportional extension. Do not use the

proportional mode to indicate the length of booms that are manually set to proportional

extension or where the operator can extend the boom sections to different lengths as needed.

IMPORTANT! Refer to the GS550/GS820 Display & GS Series Sensors - Installer and User’s Manual for complete information about installation, operation, maintenance, certification and warranty.

!

IMPORTANT! Verify display firmware for compatibly with GS012 length angle sensor. GS550 firmware to be V1016 or higher. GS820 firmware to be V1012 or higher.

1.1b Mounting the Cable Reel1. Find a clear mounting position on the left or

right side of the base section of the boom depending on cab placement. The mounting position should be so the cable reel will not obstruct free boom movement at any boom angle or slew (swing) position. When the reel is placed on the left side of the boom the cable will pay out from the top, and when on the right side the cable will pay out from the bottom.

2. If the boom top to bottom surface is not vertical, wedges will be needed to keep the cable reel top to bottom axis vertical (+/-1°).

3. Mount the welding tabs. They must be placed parallel to each other, with 17 in. (432 mm) between the holes’ centers. Install the tabs such that they create a level mounting position in line with the boom at 0°.

4. Attach the reel to the welding tabs with the bolts provided.

5. Install the first cable guide (PA111) a maximum of 3 ft (1 m) from the cable reel. Correct alignment of the first guide is critical to ensure orderly winding of the cable on the reel. This may require cutting or adding material from/to the guide prior to welding. The center of the guide should be aligned with the center of the reel drum. The guide should also be positioned up or down so that the cable passes freely

through it. Install the other guides at the end of each of the intermediate sections and the anchor (PA113) at the end of the last measured section (last section in standard mode or first telescoping section in proportional mode). All guides must be aligned to the center of the reel drum to permit unobstructed movement of the cable. This may require cutting or adding material from/to the guide prior to welding.

6. Pretension the reel by making 3 to 4 rotations. Once pre-tensioned remove enough cable to reach the anchor point without allowing the drum to rotate. Pass the cable through the guides and secure it to the anchor point with rope clamp and quick link provided.

7. Verify the boom length indicated on the display. If the boom length indicated on the display is NoCal or NotCalib, the reel needs to be calibrated. The actual boom length is the distance from the boom base pivot pin to the head sheave center as measured along a line parallel to the boom. Depending on the exact placement of the cable reel and the cable anchor the displayed length may differ from the actual length.

1.1c Boom Length Calibration Procedure

On first start-up the display will initiate the GS112 calibration process. Follow the steps indicated on screen. If the GS112 is not available, or if recalibration is required, follow the steps in the display user manual (GS550 Manual sec. 2.6c–2.6d, GS820 Display User Manual sec. 2.5c–2.5d). After a battery change, the length reference will have to be confirmed. Simply retract the boom to its minimum length and confirm.
