Page 4: Series 1-S Introduction
SERIES 1-S INTRODUCTION Series 1-S is a stand alone slew limiter intended for use on hydraulic excavators and similar machines where an upper structure rotates relative to the base structure, and where slew limits are required. Series 1-S monitors the slew position of the machine by means of counting of the teeth on the slew ring, and limits the slew movement of the machine to between two points which are set by the machine operator. -
Page 5: Switching Limits On And Off
SWITCHING SLEW LIMITS ON AND OFF Slew limits are enabled or disabled using the key switch on the front of the in cab display. The key switch has three possible positions: - No Limits - Operational - Set Limits With the key switch in the “No Limits” position no slew limits are enabled and the machine will be free to slew in both directions without interference from the 1SL system. -
Page 6: Switching Slew Limiting Off
SWITCHING SLEW LIMITING OFF Turn the key switch to the “No Limits” position. Slew limiting will be disabled, and the machine will be able to slew in both directions without restriction. SETTING SLEW LIMITS To set slew limits, turn the key switch to the “Set Limits” position. Slew the machine to either the desired Left or Right slew limit position, and press the appropriate button on the Series 1-S display - “Set Left”... -
Page 7: The Series 1-S In Use
THE SERIES 1-S IN USE With the slew limits set and the key switch turned to the “Operational” position, slew movement will only be allowed between the stored Left and Right slew limits. As a limit is approached the Series 1-S system will apply the appropriate motion cut to stop slew movement towards and through the limit. -
Page 8: Speed Of Operation And Pre-Emptive Stopping
SPEED OF OPERATION AND PRE-EMPTIVE STOPPING Series 1-S will calculate the speed of slew movement towards a limit and will apply the slew motion cut progressively earlier as the slew speed increases, thus movement at speed towards a limit will result in the slew motion cut being deployed earlier to prevent the machine momentum carrying the structure through the limit after the motion cut has been deployed. - Page 9 www.gkdtec.com M1000007 V1.3 - 05/2021...
