monitoring. These monitoring devices will prevent the
system from continued operation if high pressure
situations develop.
There are pressure sensors located on each proportioning
pump. The high pressure sensor is located at the outbound
of the fluid section.
The high pressure monitoring sensor will engage if fluid pres-
sure increases above 3200 psi.
If a high pressure situation develops, the sensor will detect
this and immediately engage the hold-in circuit.

This will disengage power to the machine and it will stop
cycling. It will also turn the heater off.

will be illuminated after the monitoring sensor engages, indi-
cating where the problem is located (ISO or Poly).
