Description

Low Level Shutdown Mode Button: This displays a “1” if chosen. If the material level 

of either the A or B component tank goes below the low level sensor, the machine 

shuts down. To recover, refill the component tank with material to above the low 

level sensor. When “0” is displayed, the low level shutdown feature is disabled.
Alarm Engage Mode Button: This displays a “1” if chosen. If the material level of 

either the A or B component tank goes below the low level sensor, the audible alarm 

is activated.
Auto Fill Engage Mode Button: This displays a “1” if chosen. This allows the low and 

high level sensors to control the fill solenoids for a transfer pump. This also enables 

the Fill Timer.
Fill Timer: This is the amount of time in seconds from when a tank fill is initiated until 

the audible alarm sounds if the tank material level does not reach the high level 

sensor. If the high level sensor is activated before the Fill Timer times out, the Fill 

Timer is reset. The Fill Timer preset value is entered in the center field for both the A 

and B tanks. The actual value of the timer is on the left for the A tank, and on the 

right for the B tank.

Shutdown Timer: This is the amount of time in seconds between when a low level 

sensor in either the A or B tank is activated and when dispensing from the PD44 is 

disabled. This insures air is not pumped through the PD44. The preset value is 

changed in the middle field and the actual value of the timer is read in the bottom 

field.

Clear Fill Fault: This button clears the Fill Timer Fault message displayed in the 

corresponding A Tank Status or B Tank Status field in the Level 1 Control Screen.

Silence Alarm Button: When the audible alarm sounds because the material level is 

low in either the A or B tank, pressing this button turns it off.
