1 Please Observe The Following (continued)
1.3 Unpacking and Inspection
Carefully unpack the Loctite
®
Spray Valve Controller and examine the items contained in the
carton. Inspect the unit for any damage that might have occurred in transit. If such damage
has occurred, notify the carrier immediately. Claims for damage must be made by the
consignee to the carrier and should be reported to the manufacturer.
1.4 Items supplied
• Controller Unit
• Power Cord & Cord Lock
• Foot Pedal – Item #98461
• Air Supply Line, 5 micron Filter & Fittings
• Fuse Assembly and Fuses (0.25 amp & 0.1 amp)
2 Description
The Loctite
®
Spray Valve Controller 98521 is a microprocessor based control unit that
provides a 3-segment time sequenced spray cycle for the Loctite
®
Spray Valve 98520.
The unit allows individual programming for each time segment
• Pre-spray atomizing
• Valve on time
• Post spray atomizing
These individually controlled time ranges provide for complete atomization of a wide
variety of fluid and ensure “no-drip” positive valve shut-off.
When the spray cycle is activated by depressing the Foot Switch, a pulse of air through
Port A is transmitted to the valve’ air cylinder to open the valve and a second pulse of
air through Port B is transmitted to the valve’s spray cap to spray the fluid.
The amount of fluid sprayed is controlled by the spray cycle on time, fluid pressure
and stroke setting on the Loctite
®
Spray Valve.

3.Using the chart (previous page), select Fuse & Voltage setting required.
4. If the voltage in not correctly set, remove the voltage selector from the fuse holder and
reinstall it with the desired voltage shown at the window of the fuse holder.
NOTE: Make certain fuse replacement is proper type and rating.
5. Reinsert the fuse holder into the AC Connector casing until it snaps into place.
4.4 Connecting the unit
1. Connect 70-100 psi dry, filtered air supply to air inlet fitting. Make sure the air
inlet pressure is at least 70 psi.
The 5-micron filter should be installed with the unit to ensure proper ai
r
filtration 985397.
2. Install the cord lock to the cord lock mount with the slot at the bottom.
3. Lift the cord lock and connect the foot switch plug to foot switch receptacle.
4. Fit the cord lock over the foot switch cable.
5. For circuit protection, the unit is shipped with fuse unassembled. Follow
instructions in the Fuse Installation section 4.3 to install fuse and set proper
voltage.
6. Connect the power cord to a grounded, properly rated voltage outlet.
Connect the valve air hose to Port A and atomizing air hose.
4.5 I/O Configuration and End of Cycle Switching
Upon completion of a dispense cycle, an open collector circuit closes and remains
closed until the next dispense cycle. This circuit can be used to signal back to a
host computer, start another device in sequence, or drive any other operations that
needs to be tied to the completion of the dispense cycle.
Upon closure, (end of dispense cycle), power from an external source is allowed to
pass through the circuit to operate a 5 to 24 VDC load. Power consumption must
not exceed 250 mA. The load could be a relay, solenoid, counter, LED, or any
device that will operate within a 5 to 24 VDC range and a maximum of 250 mA.
