Grounding
Grounding
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.
Pump: follow instructions in separate feed pump manual, supplied.
HFR: see operation manual.
Fluid supply container: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray gun or
dispense valve firmly to the side of a grounded metal
pail, then trigger the gun or valve.
Flush Pumps Before
Using
Flush equipment only in a well-ventilated area. Do
not spray flammable fluids.
NOTICE
Diaphragm pumps are factory tested with water.
Thoroughly flush pumps before using to prevent
moisture contamination when pumping moisture
sensitive materials.

NOTE: Setting this option initiates a deviation condition
and disables the machine from operation when there is
a low level condition. When a low level is sensed, the
machine will not cycle until the sensor see material. A
pop-up screen on the ADM alerts the operator of the
specific level condition.
4. If it is not desired to stop dispense, verify Low Mate-
rial Disables Dispense” is unchecked.
NOTE: This option is the default setting of the system
and is set as a deviation condition. When a deviation is
issued, the machine will continue to cycle and will not be
affected by the deviation.
NOTE: A low level condition generates a pop-up message on the ADM that can only be cleared by the operator. If the “Low Material Disables Dispense” option is
selected, dispensing can resume with a remote start
signal when material is replenished and the sensor sees
material. It is not necessary to clear the ADM to initiate a
start unless the ADM is used as the start device.

and then measure the depth of the hole in the fitting
where the well is inserted. Note these measurements as they will be needed later.
8. Being careful to not cross-threads, thread assembled level sensor (CB) into well housing until it bottoms out against the bottom of the well. The bottom
of the level sensor will be slightly visible through the
bottom of the well.
12. The protrusion length must be at least 1/8 in.
(3.2 mm). If not, remove the level sensor well and
restart at step 7.
NOTICE
Level sensor must be oriented with the sensing face
pointing down. Alternate orientations could result in
material pooling on the sensor face, resulting in a
false reading.

This screen is for enabling the optional ADM screens,
enabling USB log downloading, and erasing USB logs.
To enable the machine to automatically stop dispensing
when a reservoir is low: place an “X” beside the “Low
Material Disables Dispense” check box. When this feature is active, the machine will not cycle unless material
is present in the monitored reservoirs.
• Temperature Alarm Disables Dispense: When
this box is checked, the system will reject dispense
requests when any enabled heat/chiller zones are
below/above their setpoint.
• Enable Operator Mode Cavitation Alarm: Check
this box to enable cavitation alarms in Operator
Mode. Clear this box to disable cavitation alarms in
Operator Mode.
• Complete Dispense with Setpoint Error: When
this box is checked, the shot will continue dispensing even if the system never reaches the desired
