Electrical Installation
1.
Hazardous Location Precautions:
Observe the regulations listed in the National Electrical Code
regarding equipment in hazardous locations. In particular, ensure power is disconnected whenever
the cover is removed, ensure the cover and case mating surfaces are not damaged and upon
completion, ensure cover screws are secure and that no gaskets or sealer has been used between
the cover and case surfaces.
2.
Output Contacts:
Route wires through the 1/2" NPT conduit entrance. No power is required to
operate the diaphragm bin monitors. All electrical installation is done directly to the terminals of the
output switch. The switch terminals are designated with “3” (COM - common), “2” (N.C.- normally
closed) and “1” (N.O. - normally open). When the diaphragm is not sensing material, the switch
is in the normal condition (i.e. N.C. contact is closed to COM and N.O. contact is open to COM).
However, when the diaphragm senses material, the switch is opposite from normal condition
(i.e. N.C. contact is open to COM and N.O. contact is closed to COM). Be sure to comply with
all electrical specifications listed within this bulletin.
