TB1, TB2 and TB5 connections can share the same cable requiring only one screen connection at the display panel
end. If separate cables are used, each cable must have its own screen connection e.g. TB1 Scr, TB2 Scr and TB5 Scr.
3.1. MOUNTING THE DISPLAY UNIT
3.1.1 Wiring the SPS-SHIELDLITEDB display panel
Display panel mounting considerations
•DISPLAY PANEL MUST BE MOUNTED AT FILL POINT VISIBLE TO DRIVER.
•Power from an isolatable power supply.
•Mount at head height so easily viewable and within comfortable reach.
•Protect from the elements –use weather cover supplied.

3.3 PRV MOUNTING CONSIDERATIONS
When positioning the spigot allow for a 40” (1.0m) diameter footprint free of any obstructions for correct
positioning, wiring and removal of covers. Be aware of the following points:-
•
•DO NOT mount probe in fill path of the material as this
will cause premature wear and failure.
•Ensure there is sufficient space to remove and install
probes for maintenance.
•DO NOT install in front of ladder access.
•We recommend removal of old PRVs to prevent false
venting.
•Mount as close to filter as possible but not in way of fill.
•Beware of internal fill pipes, ladders, split silos etc.
We recommend cutting the main access hole after welding
on the spigot.
3.4 REMOVING THE HIGH LEVEL PROBE FROM UNDERSIDE OF PRV
The high level probe of the SPS-SHIELDLITE20 system comes pre-fitted on the side of the PRV and already wired to
the PRV control box. Ensure to remove the level probe sensor from the underside of the PRV prior to installation by
cutting the 3 cable ties and removing the plastic tip protector.
3.5 WIRING THE SPS-SHIELDLITECB PRV CONTROL BOX
WARNING! NEVER APPLY AC MAINS VOLTAGE TO CONTROL BOX.
Remove cover of control box and wire the following cables to the control box’s PCB using the glands as shown in
Figure 8: -
1) Wire 4-core screened supply and communications cable from the
SPS-SHIELDLITEDB display panel TB8 to control box TB11.
2) Wire 3-core screened cable between control box TB3 and Hycontrol
HYVENT silo filter - see section 3.6.1.
The control box wiring is now complete.

3.6 WIRING THE ANCILLARIES
3.7 CONNECTING THE AIR-LINE
Connect the air-line into the pressure regulator as shown in Figure 11 and
check pressure on gauge is at 6 bar.
Note: - The air supply MUST be clean and dry and filtered to 25 microns.
4. COMMISSIONING
After completing the mechanical, electrical and pneumatic installation perform the following checks: -
Pre commissioning checks
1. Air pressure regulator on the SPS-SHIELDLITE PRV should be set at 6.0 bar (87psi).
2. Air pressure at the fill valve should be at least a constant 6 bar (87psi). Consider other demands on the
air supply which might affect this.
3. Confirm the specified AC voltage to the display panel (100V –240V AC 50Hz/60Hz).
4. Confirm the 24VDC output from the display panel at TB8 between pins 0V and +24V.
See section 3.1.1 for connector location.
Commissioning checks
5. At start-up, ensure the display shows the “SPS SHIELD LITE GLT key to start” screen.
6. Switch the GLT key-switch clockwise and release. If the initial check passes then the beacon and siren will flash
for five seconds during the test.
7. If the test is successful, the display will show “Safe to fill 90 min remaining”, the fill valve will open and a
delivery can commence.
8. If the test fails, a message will be displayed and the fill valve will remain closed. At this point further
investigation is required as to the cause of the test failure. See Trouble shooting section of full manual for
further details.
5. FURTHER INFORMATION
Hycontrol provides complete documentation and instructional videos for installing, commissioning, and operating
the SHIELD Lite system. Rather than multiple manuals for different components, SHIELD Lite requires only one.
All these resources are available through Hycontrol’s specialist website, www.siloprotection.com.
