Appendix B - ADM Setup Screens Overview
• Red Tank Leak detect On and Blue Tank leak
Detect On: These controls will become enabled
(not greyed out) if the corresponding tank system is
online. If the function is enabled (checked) the tank
stand logic will generate a leak error if more than
two automatic fill operations occur, and no dis-
penses have occurred during that time.
• Use ADM to Program Token: If checked, the user
will be able to update the system software by using
the ADM to program a token, as described in Pro-
gramming Tokens/Updating System Software
section page 46.

Advanced Screen 6

Tap to High Pressure Recirculation – This feature if
checked (default is NOT checked), will command the
HFR to interpret a footswitch tap as a go to high pres-
sure recirculation mode, but will NOT dispense material
(same as pressing the "
screen). This feature only applies to full recirculation
systems (S-Head, S-Head with Prox., and L-Head dis-
pense valve options), and is disabled if the system is
NOT a full recirculation system.
Other items on this screen do not pertain to full recircu-
lation systems and are therefore disabled.
Advanced Screen 7
The HFR setup Advanced #7 screen contains the fol-
lowing control options:
• Disable Pressure Imbalance Alarms – Checking
this option will disable the generation of pressure
imbalance alarms resulting from an excessive pres-
sure difference between the HFR Blue and Red
pumps. This control is intended to make the initial
installation of the HFR easier, and is typically not
intended to be "checked" when the machine is
used for production. This is especially true for
impingement type dispense valve options (GX-16,
GX-16 with Prox, L-Head) where excessive pres-
sure differences can cause problems within the dis-
pense valve.
• Control Dispense Ready Light – Checking this
option will reassign the I/O originally used to sense
an optional hydraulic tank low level sensor to an
output for driving a ready lamp. Typically a ready
lamp (LED) is installed in the handle of a dispense
valve.
When this function is checked or turned ON, the
ready lamp will be in one of the following states:
