N12- G & HW Series Frequency Controllers 115/230VAC
Mounting
The controller should be mounted in a reasonably dry,
minimum dust area, if possible, where the ambient
temperature does not exceed 100°F. It is designed
for vertical mounting. Refer to the supplied schematic
and outline drawing for mounting dimensions. The
mounting site should be relatively free of vibration or
steps should be taken to isolate the unit.
Wiring
Refer to the supplied schematic and outline drawing
for connections. The installation of a fused safety
switch or branch circuit breaker ahead of the controller
is recommended.
Connections
Input Cable
120/230 VAC supply voltage
Output Cable Output - Eriez feeder
Set-up
Using the buttons and the LED display located on
a touch plate on the front panel sets up this unit.
The feeder throughput adjustment and setting of
other parameters can be carried out by using these
components. The control can also be operated by
external means, such as potentiometers and signal
sources. The parameters can be changed by scrolling
through the menu, which is accessed by a user
password. The various functions within the menu are
identified with capital letters for ease of recognition.
Enable and fault contacts are located inside the
control enclosure along with other user connection
points. The output power is shown in percent (%) on
the LED display during normal operation. Changed
settings are saved when leaving programming mode
or after a 100 second delay from when the last key
was pressed.
