INSTALLATION
Using the Model 273 base diagram, pictured on the unit
(contacts shown in the de-energized condition), connect
operating voltage and current input wiring to the socket.
PIN DRAWING
ADJUSTMENT SETTINGS
The output contacts used will depend on whether the Model
273 is applied to detect over current, under current, to shut off
a load, or trip an alarm.
The internal relay will energize when the input current rises
above the Current Adjust setting. This allows the unit to be
set to detect over-current (relay will energize on fault). The
LED indicator will illuminate whenever the relay is energized.
Apply normal operating current, then adjust the Model 273
Monitor until the relay just trips or resets, depending on the
application. This will result in the unit tripping on relatively
small current changes.
NOTE:
of high humidity or contamination, it is recommended that the
base area and all exposed metal parts of the socket be coated
liberally with a good quality silicon grease, such as Dow Corning
DC-4 or DC-4X. Insert the unit into the socket and wipe off excess
grease around the base. This will prevent the entrance of moisture
