Pouring Operation

Low and High Pressure 
Circulation

When the metering pump motors are first turned on, the 
machine will enter low pressure circulation. After that 
the machine will stay in or return to low pressure circula-
tion if the following conditions are met.

A pour has not occurred since the metering pump 
motors were started

If the preset High Pressure Hold Time has elapsed 
since the last pour occurred and calibrate mode has 
not been selected.

When any of the following conditions are met, the 
machine will be in high pressure circulation.

The pour start button has been pressed but Pres-
sure-Build Time has not yet elapsed

A pour has finished but High Pressure Hold Time 
has not yet elapsed

Pouring Requirements

The following requirements must be met in order for a 
pour to occur. 

Main Power on

Control Power on

Night Mode off

Manual or Automatic Mode selected

Iso and Poly Metering Pump Motors on

Iso and Poly Fail To Build Pour Pressure Alarm inac-
tive

Iso and Poly Low Pour Pressure Alarm inactive

Iso and Poly Tank Low Level Alarms inactive

If all of the above requirements are satisfied, then the 
“MixHead Pour Ready” indicator on the Status Screen 
will be green, see page 19.

Beginning the Pour

After both streams reach the required pour pressure and 
the preset pressure build time elapses, the MixHead is 
commanded to open and the pour occurs.
