INSTALLATION GUIDE
H540NS/548NS
calibration (H548ns only)
Note: Testing the solid-state status output of this sensor with a digital ohmmeter
may yield inaccurate, but relative readings of switching (e.g. 6 MΩ) Use an analog
V-O-M for readings similar to loop values. Calibration to be done while motor is
running normally.
1. For under-current status indication: (Belt loss, fan & pump status)
• Turn the set point screw clockwise until the status closed LED goes out
and the status open LED comes on.
• Turn the set point screw counter-clockwise until the status open LED goes
out and the status closed LED comes on.
• Turn the set point screw 1/2 turn counter-clockwise.
• The sensor is now calibrated to provide indication of current flow below
normal full load amps.
Output Status:
Normal: Output closed
Alarm: Output open
2. For over-current status indication: (Locked rotor)
• Turn the set point screw counter-clockwise until the status open LED goes
out and the status closed LED comes on.
• Turn the set point screw clockwise until the status closed LED goes out
and the status open LED comes on.
• Turn the set point screw clockwise 1/2 turn
• The sensor is now calibrated to provide indication of current flows above
normal full load amps
Output Status:
Normal: Output open
Alarm: Output closed
c.) surface mounting:
Line Voltage
Wires
Connect line voltage wires
to line current terminals
Wire the 12 AWG lines from the controller through the side of the device, onto
the line current terminals. Tighten line current terminal blocks to 12 in-lb
(1.35 N-m) torque.
d.) nipple mount to another enclosure:
Insert the conduit nuts (provided) into the slots in the side hole of the device
for additional weight support.
Connect line voltage wires
to line current terminals
ENCLOSURE
Nipple to existing enclosure
(conduit nipple fitting not
provided)
Line voltage wires
Wire the 12 AWG lines from the controller through the side of the device,
from the enclosure to the line current terminals. Tighten line current terminal
blocks to 12 in-lb (1.35 N-m) torque.
5. Use the knockout seal to cover any unused holes in the housing. Attach the cover,
securing with the screws provided.
NOTE: If a conduit is used, connect the conduit to the mounting hub before connecting it to
the device. Be sure to support the H540NS/548NS housing when nipple‑mounted to another
enclosure, or the unit may shift on opening, potentially causing undue stress on the wiring and
the terminals.
