Recirculation and Purge Timers The Purge Timer and Recirculation Timer behave in a
similar way, with a certain shot size (HD, HH) being exe-
cuted after the timer delay (HC, HG) has elapsed. The
difference is that the purge timer operates with the dis-
pense valve open so a purge shot is executed. The
recirculation timer operates with the dispense valve
closed so when the shot is executed no material is dis-
pensed.
Both timers feature an adjustable alarm to warn the user
that the piston drive block is to begin moving. The alarm
setting is the number of seconds before the shot is to be
executed.

To use Recirculation mode, 3-way ball valves must
be installed at the dispense head. Fluid lines must
be installed going from the ball valves back to the
tank.
When Recirculation mode is enabled, both recircula-
tion ball valves must be turned to return material
back to the tank. Only turning one valve may result in
a pressure imbalance exceeding the machine’s maxi-
mum working pressure.
