GENERAL
BEFORE INSTALLING, CHECK THE SENSOR
MODEL SELECTED FOR COMPATIBILITY TO
THE PROCESS MEDIA IN CONTACT WITH THE
SENSOR AND WETTED PARTS.
J6 pressure switches are activated when a bellows or piston
sensor responds to a pressure change. This response
actuates a single snap-action switch, converting the
pressure signal into an electrical signal.
Set point may be varied by turning the internal adjustment
screw according to procedures outlined below.

MOUNTING
J6 pressure switches may be mounted and operated in
any position. They may be surface mounted via the two
mounting ears on either side of the enclosure, or mounted
directly to a rigid pipe by using the pressure connection.
LOCATE THE UNIT WHERE VIBRATION, SHOCK
AND AMBIENT TEMPERATURE CHANGES ARE
MINIMAL. SHOULD THE UNIT BE INSTALLED
WHERE CONDENSATION IS EXPECTED, VERTICAL
MOUNTING IS RECOMMENDED.
NEVER USE THE ENCLOSURE FOR LEVERAGE
TO
HAND
TIGHTEN
THE

On models supplied with an external manual reset button,
be sure to leave sufficient finger space over the reset button
for the operator to reset the switch.
