NOTE: Control unit shipped may be different than what is shown. NOTE: Outside Light Assembly shipped may be different than what is shown.
INSTALLATION MOUNTING AND ANCHORING Inspect installation location: The POWERHOLD restraint will require solid anchors to assure proper operation. Optimum installations will have both a concrete drive and a poured concrete dock face so that anchor bolts can be well secured. Twelve 1/2" anchor bolt mounting holes are re provided. However, 6 base or 6 wall may be used where cold induced frost heave will be a factor or mounting conditions do not allow use of all 12 mounting holes.
INSTALLATION CONTINUED ELECTRICAL Refer to the drawings indicated in Table I for the electrical installation. The drawings are attached to this manual. IMPORTANT Make sure that the power supply requirement(s) as shown on the electrical drawings and on the decal of the control assembly(s) are the correct requirement(s) for the application.
GENERAL INFORMATION DESCRIPTION OF OPERATING MODES A. "NORMAL" OPERATING MODE Used to operate the POWERHOLD restraint to engage the truck ICC bar. An auto-raise cycle will be activated by momentary pressure on the "LOCK" push button (Note: Pressure on the "LOCK" push button must be maintained until the inside lights change from red to amber). An AUTO-LOWER cycle will be activated by momentary pressure on the "UNLOCK" push button.
GENERAL INFORMATION CONTINUED DESCRIPTION OF SIGNAL LIGHTS: A. INSIDE SIGNAL LIGHTS. These lights are typically located on the PLC/ LOGIC control assembly. the assembly housing the light is to be mounted in a location that is clearly visible to the dock attendant. WHEN THE LIGHT IS ON: RED LIGHT R • IT INDICATES TO THE DOCK ATTENDANT THAT IT IS NOT OK TO ENTER THE TRUCK. THE TRUCK ICC BAR IS NOT ENGAGED BY THE POWERHOLD RESTRAINT. THE BYPASS MODE AND WHEEL CHOCKS MAY BE REQUIRED.
GENERAL INFORMATION CONTINUED SIGNAL LIGHTS AND ALARM SEQUENCE OF OPERATION A. "NORMAL" operating mode - truck ICC bar engaged. 1. The POWERHOLD restraint is in the fully lowered (stored) position. Limit switch "LS3" is closed. Outside light = Green Inside light = Red Alarm = Off 2. The POWERHOLD restraint is activated. a. The unit leaves the fully lowered (stored) position. Limit switch "LS3" is open. Outside light = Red Inside light = Amber Alarm = Off b.
GENERAL INFORMATION CONTINUED SIGNAL LIGHTS AND ALARM SEQUENCE OF OPERATION CONTINUED. D. The unit reaches the fully lowered (stored) position. Limit switch"LS3" is closed. Outside light = Green Inside light = Red Alarm = Off D. "BYPASS" operating mode Outside light = Red at all times Inside light = Amber at all times Alarm = Off at all times OPERATING NOTES A.
GENERAL INFORMATION CONTINUED Also, the restraint will automatically shut off after the 13 second delay if the unit reaches the stored position but the "LS3" limit switch in the unit has failed "OPEN". D. If power is lost after the restraint is activated, the automatic raise and lower cycles will be disabled. Thus, when power is restored the restraint must be reactivated to either the fully raised ICC bar engaged position or the stored position.
OPERATING INSTRUCTIONS NORMAL OPERATION 1. Set the "ON-OFF" switch to "ON". 2. Set the "NORMAL-BYPASS" key switch to "NORMAL". 3. Requirements for proper restraint operation are that the truck be parked perpendicular to the loading dock area with its ICC bar from 4-1/2" to 14-1/2" from the face of the dock when 4-1/2" bumpers are used. If 6" bumpers are used, the horizontal range would be from 6" to 16" from the face of the dock. 4.
MAINTENANCE CLEANING The POWERHOLD restraint should be kept free of debris, ice, dirt and sand. Build-ups of foreign material, especially on the top of the slide block assembly, could result in abnormal operation of the restraint. LUBRICATION Lubrication should be performed on a monthly basis. Use Lubriplate No. 18339 multipurpose grease or equivalent. Remove all of the old grease from the slide block guide channels and from the top of the slide block before applying the new grease.
MECHANICAL RELEASE The POWERHOLD restraint is equipped with a mechanical release that can be utilized in the event of an electric and/or hydraulic failure which prevents the unit from releasing the truck ICC bar via normal operating methods.
