Operator Adjustments
WARNING HIGH PRESSURE PRESENT
The following procedure will require the adhesive to be at a high temperature
and the application system to have substantial pressure.
Safety glasses, insulated gloves and long-sleeved protective clothing must be
worn to prevent the possibility of serious injury from the hot adhesive.
Controller
See Chapter 6 for complete information and programming of the controller.
Program temperature set points, alarms, level control, etc., appropriate for your
production.
System Pressure
System pressure is regulated by the piston pump air pressure setting, material viscosity
and the pump pressure relief valve setting.
The system pressure relief valve is typically factory set to 500 psi (35 bar). It is located on
the back side of the controller’s panel box.
Prior to system pressure relief valve adjustment, turn the system ON and raise the
temperatures of all components to normal operating temperatures. At the controller, first
set the pump/ motor OFF so that the motor is not turning. Then set the pump/ motor ON.
Locate the air prep assembly exhaust valve (red). Open (actuate) the valves on the
applicators in order to fill them with adhesive and purge air from the system. Then close
the valves to stop adhesive flow.
To adjust the pressure relief valve turn the adjustment dial counterclockwise to decrease
pressure or clockwise to increase pressure. After desired pressure is achieved, tighten
the lock nut.
Maximum operating pressure should not exceed 1000 psi.
DO NOT set the adjustment screw fully clockwise (closed) or serious pump damage
