4.2 THE I-LOCK CONTROL VALVE
The I-Lock Coupler is designed to operate on the carrier machine’s
MAINS PRESSURE
supply. The I-Lock Control Valve controls the oil pressure and oil flow to the coupler
for both the Primary Wedge function AND the Safety Knuckle function. The I-Lock
Coupler Control Valve
MUST BE USED
for any installation of an I-Lock Coupler.
•
The I-Lock Control Valve consists of twin solenoid valves, one pressure reducing
valve and 5 ports for hose routing. The distinguishable markings are there to assist with the
electrical connection and hose routing to ensure that the coupler operates in accordance with
which it has been designed. (Fig 4.2.1)
•
The markings on the control valve are as follows.
Twin Solenoid Valves
•
SAFETY – safety knuckle solenoid.
•
WEDGE – primary wedge solenoid.
One Pressure Reducing Valve
•
1. PRV set to 145 Bar
5 Ports for hose routing
•
P – pressure in.
•
T – tank return.
•
RET – primary wedge retract.
• EXT – primary wedge extend.
•
SAFETY – safety knuckle release.
• For pressure settings refer to the pressure settings chart on page 20.
•
For service details regarding the control valve refer to the service section in the Operators
Manual.
4.3 INSTALLING THE CONTROL VALVE
• Identify the pump that delivers flow to the BUCKET CURL CYLINDER of the carrier machine.
This is the most common pump used for hydraulic couplers operating on
mains pressure (refer to the carrier machine service manual if required).
•
Utilizing the mounting plate supplied determine a suitable location in the
pump / engine compartment of the carrier machine to mount the control
valve. The mounting plate can either be welded or bolted into position. (Fig
4.3.1 Mounting Plate)
•
Bolt the Control Valve to the mounting plate with the bolts provided.
NOTE:
The best position for mounting of the control valve may be determined after the hose routing
from the boom to the pump compartment. Check where the hoses exit from the boom end in the
pump compartment before mounting the valve as the I-Lock hoses will invariable follow this same
route.
