If the control unit does not receive data that foam concentrate is flowing, it
displays the “No Pri” error message, indicating no prime, and turns the sys-
tem OFF. Pressing ON starts the cycle again. There must be water flow or
the unit must be in the simulated flow mode. (See Section 5, “Operation,”
on page 121 for more information.)
Summary
FoamLogix replacement parts are “plug-and-play” type devices that do not
require specialized equipment to service. Normal water flow and foam cali-
bration is usually necessary after a major component service.
The procedures that follow provide a logical flow path to isolate and correct
system failures.
7.3 PROBLEM ISOLATION
The first step in troubleshooting is to determine which subsystem caused
the system failure. Operate the apparatus and Hale FoamLogix system in
accordance with standard operating procedures and isolate where the prob-
lem occurs.
Use the troubleshooting charts (See Chart 7-3: “Hale FoamLogix System
Troubleshooting Flow Chart,” on page 146.), together with Chart 7-4: “Power
System Troubleshooting,” on page 147, to diagnose or trace a field problem
to a particular component – repair and/or replace accordingly.
Also review the following steps.
1. Setup the apparatus for normal operation.
2. Power-up the apparatus and energize the pump operator panel.
Take notice of the Hale FoamLogix control unit. If the display is NOT illuminated
proceed to Chart 7-3: “Hale FoamLogix System Troubleshooting Flow Chart,”
on page 146.
3. If the Hale FoamLogix control unit is illuminated, engage the apparatus water
pump and establish discharge.
If water flow CANNOT be established, troubleshoot the water pump system.
