MultiPoint Level Control System 7 Disable the Gun All electrical or mechanical devices that provide an activation signal to the gun solenoid(s) or the melter pump must be disabled before work can be performed on or around a gun that is connected to a pressurized system. 1. Turn off or disconnect the gun triggering device (pattern controller, timer, PLC, etc.) 2. Disconnect the input signal wiring to the gun solenoid valve(s). 3.
8 MultiPoint Level Control System General Safety Warnings and Cautions (contd) WARNING: System pressurized! Relieve system hydraulic pressure before breaking any hydraulic connection or seal. Failure to relieve the system hydraulic pressure can result in the uncontrolled release of hot melt that can cause personal injury. WARNING: Molten Material! Wear eye or face protection, clothing that protects exposed skin, and heat-protective gloves when servicing equipment that contains molten hot melt.
MultiPoint Level Control System 9 WARNING: Allow only personnel with appropriate training and experience to operate or service the equipment. The use of untrained or inexperienced personnel to operate or service the equipment can result in injury, including death, to themselves and others, and damage to the equipment. CAUTION: Hot surfaces! Avoid contact with the hot metal surfaces of guns, hoses, and certain components of the melter.
10 MultiPoint Level Control System Other Safety Precautions S Do not use an open flame to heat hot melt system components. S Check high pressure hoses daily for signs of excessive wear or damage. S Never point a dispensing handgun at yourself or others. S Suspend dispensing handguns by their proper suspension point. First Aid If molten hot melt comes in contact with your skin: 1. Do NOT attempt to remove the molten hot melt from your skin. 2.
11 MultiPoint Level Control System 2. System Overview System Description The MultiPoint Level Controller automatically senses the adhesive level in the applicator’s tank, thereby eliminating the need for an operator to manually fill each unit. The Controller is responsible for refill, shutoff, and alarm functions. See Figure 1. The MultiPoint Level Control System consists of the Control Box, the RIA 450 Level Controller, the MultiCap Probe and the Lid Kit.
12 MultiPoint Level Control System The level control process starts when a low voltage, high frequency signal is sensed and sent to the capacitance MultiCap Probe then to the ground plane. The control relay is calibrated to ignore this signal unless hot material contacts the MultiCap Probe. If hot melt material contacts the MultiCap Probe, additional current flows to the ground, is sensed, and amplified by the control relay. Internal circuitry reads this amplified signal and regulates the filling process.
13 MultiPoint Level Control System Control Box The Control Box is used as the connecting unit for the Endres+Hauser RIA 450 Controller, MultiCap Probe, lid kit, and optionally an automatic gun. All operator controls and indicators are located on the control box front panel. See Figure 3, Front View of Controller. 12 11 10 MANUAL 1 AUTO OFF MAN 9 OVER 8 NORMAL AUTO SILENCE ON 7 UNDER OFF 6 5 4 2, 3 6901002A Fig. 3 1. 2. 3. 4.
14 MultiPoint Level Control System RIA 450 Controller WARNING: Warning on RIA 450 Level Controller: Disconnect power before opening cabinet ground equipment. Failure to follow these instructions may result in death. The Endres+Hauser RIA 450 Controller is a subassembly of the Control Box. The Controller has four user programmable setpoints and each setpoint has a user programmable hysteresis. The Controller is responsible for refill, shutoff, and alarm functions as follows.
15 MultiPoint Level Control System MultiCap Probe The MultiCap Probe contains an FEC 12 electronic insert that functions as a transmitter for capacitance measurement. Capacitance measurement functions: S The MultiCap Probe and vessel form a capacitor. S Depending on the level, the space between these capacitor plates is filled either with air (empty vessel) or an unspecified quantity of material.
16 MultiPoint Level Control System 3. Installation This section contains the installation procedures necessary to install the MultiPoint Level Control System for various applicators. Inventory and inspect the MultiPoint Level Control System components. The gun, solenoid, and filter/regulator are ordered and shipped separately. WARNING: Warning on RIA 450 Level Controller: Disconnect power before opening cabinet ground equipment. Failure to follow these instructions may result in death. 1.
MultiPoint Level Control System Mounting the Level Control Cabinet 17 1. Mount the level control cabinet in a location as far away as possible from vibration, corrosive atmosphere and potential mechanical damage. NOTE: in order to prevent signal drop-off, it is recommended that the level control cabinet be located as close as possible to the filling cabinet. (This instruction applies to the distance between the feed unit and the level control box). Wiring Instructions 1.
18 MultiPoint Level Control System Wiring Instructions (contd) 5. Route a 1-phase, 120 VAC input power supply line through the strain relief and connect it to terminals XT1-1 and XT1-2 inside the level control cabinet. 6. Connect the input power supply line ground wire to XT1-3 inside the level control cabinet. 7. Refer to feed unit manual and applicator manuals for specific setups. 4. System Setup Verifying Program Values Fig. 6 The RIA 450 Level Controller is pre-programmed prior to shipping.

MultiPoint Level Control System Operating Modes 21 The level control may be set for any of three modes: S OFF: The RIA 450 Level Controller does not function. S AUTO: The RIA 450 Level Controller circuitry activates the pump/automatic gun when the level of material in the tank/hopper reaches the REFILL START setpoint and deactivates the pump/automatic gun when the level reaches the REFILL SHUTOFF setpoint. An alarm sounds when a high or low alarm setpoint is reached.
22 MultiPoint Level Control System High Level (contd) The equipment operator must: S Press the Horn SILENCE button to deactivate the alarm. S Stop the fill process that caused the overfilling and lower the amount of material in the tank/hopper to the Refill Start Setpoint (the OVER lamp goes off, the NORMAL lamp goes on and the RIA 450 Level Controller will activate the pump/automatic gun as required.
MultiPoint Level Control System Calibration 23 MultiCap Probe/FEC 12 Electronic Insert Calibration Procedures Calibration is carried out at the FEC 12 Electronic Insert by using four pushbuttons. (See Figure 8). 1. Press the two push buttons on the left of the MultiCap Probe simultaneously (6) when the material is just touching the bottom of MultiCap Probe to set low point. 2. Press and hold the 2 push buttons (6) until LED illuminates (5). 3.
