Setup
In this example, the heat control box on Pump 1 (P1) is
the one selected to heat the shared components
running from the Tandem Block (R) to the Dispense
Valve (B).
1. Press the soft key to enter editing mode.
2. Configure your Zone Type and setpoint and setback
temperatures as described in Heat Setup Screen 1
on page 28.
3. Use the key to enable the zones under P1 that
will control the heat for the entire system.
NOTE: Since P1 will be the heat control for the shared
components, you need to enable the same zones for P2
while at the Heat 1 screen. This sets P1 to control the
heat for its pump, platen, and hose while also controlling
the heat for the components that P1 and P2 share.
4. Use the key to enable the zones under P2 that
are enabled under P1.
5. Use the ADM Directional Keypad (CH) to move to
Heat 2 in the Menu Bar.
6. Use the key to enable only the pump and
platen zones and the zone for the hose that runs
from the ram supply unit for P2 to the Ball Valve (S)
on the Tandem Block (R) since all others are
controlled by P1.
7. Press the soft key to save your changes and
exit editing mode.

Heat Setup Screen 2 - Heat Soak
Use the ADM Directional Keypad (CH) to navigate to
Heat screen 2. This screen is the same for Ram and
Tandem except for the additional Heat 2 selection in the
Menu Bar. Make sure you configure heat soak time for
both Heat 1 and Heat 2 in a Tandem system.
Press the soft key to enter editing mode.
The heat soak time in the far right column is the amount
of additional time that the heat zone needs to ensure
that the material is heated evenly throughout after the
zone is up to temperature. Enter a time in minutes.
NOTE: Three minutes is the minimum amount of heat
soak time needed to make sure that the dispense valve
is completely up to temperature.
The Zone Types can only be changed at the Heat Setup
screen 1. See Heat Setup Screen 1 on page 28.
Press the soft key to save your changes and exit
this screen.
