Load Cell Installation
Connecting a load cell or configuring jumpers requires the removal of the rear panel.
Follow the
GuardianXL
Installation Manual guidelines for working with the
GuardianXL
in a hazardous environment.
Removing the Rear Panel
Before you remove the rear panel, remove the AC power from the
GuardianXL
.
Removing the rear panel requires a 5/16” nut driver. Remove all four screws and set
aside. Do not loosen any water tights on the back panel that do not require modification.
Replacing the Rear Panel
Secure any connections that have been modified. When replacing the rear panel it is
necessary to mount the gasket, all four screws and gasket washers. Tighten all four
screws to 20 ft-lb to achieve proper sealing. It is normal for the rear panel to dimple
slightly when the screws are tightened to 20 ft-lb. Tighten any modified watertight until
the cable exiting the watertight can no longer slide through the watertight – this is usually
finger tight. With an open-end wrench, apply a quarter turn to the watertight for a tight
seal.
Load Cell Installation
Single Load Cell Installation
To install a single load cell, remove the rear panel and check the JU3 and JU4 jumper
configuration. Remove JU3 and JU4 for a six-wire load cell. Inversely, JU3 and JU4
must be in place for a four-wire load cell. To install the load cell wires, press the load
cell connector arm back with either your finger or a non-conductive object.
Multiple Load Cell Installation
Four load cell systems will degrade the battery life between charging due to the
additional load placed on the electronics. It is recommended that multiple load cell
installations use 1000
Ω
load cells.
