Mounting to a DIN Rail
Install module vertically on a 35 mm DIN rail in a protective
enclosure away from heat sources. Do not block air flow. Allow
1" (25 mm) above and below housing vents for air circulation.

Removal
Avoid shock hazards! Turn signal input, output, and power off
before removing module.
1. Push up on bottom back of module.
2. Tilt front of module downward to release Upper Mount from top
edge of DIN rail.
3. The module can now be removed
from the DIN rail.
Calibration
Input and output ranges, if specified on your order, are factory
pre-configured (at 24°C ±1°C).
Front-mounted Zero and Span potentiometers are used to
calibrate the output to compensate for load and lead variations.
Note: Perform the following calibration procedure any time
switch settings are changed.
1. Apply power to the module and allow a minimum 20 min-
ute warm up time.
2. Using an accurate calibration source, provide an input to
the module equal to the minimum input required for the
application.
3. Using an accurate measurement device for the output,
adjust the Zero potentiometer for the exact minimum
output desired. The Zero control should only be adjusted
when the input signal is at its minimum. This will produce
the corresponding minimum output signal. For example: 4
mA for a 4-20 mA output or –10 V for a ±10V output.
4. Set the input at maximum and adjust the Span pot for the
exact maximum output desired. The Span control should
only be adjusted when the input signal is at its maximum.
This will produce the corresponding maximum output
signal. Example: for 4-20 mA output, the Span control will
provide adjustment for the 20 mA or high end of the signal.
5. Repeat adjustments for maximum accuracy.
Output Test Function
When the Test button is depressed it will drive the output with a
known good signal that can be used as a diagnostic aid during
initial start-up or troubleshooting. When released, the output
will return to normal.
The Test Cal. potentiometer is factory set to approximately
50% output. It can be adjusted to set the test output from 0 to
100% of the output span. Press and hold the Test button and
adjust the Test Cal. potentiometer for the desired output level.
Operation
The APD 6380 accepts an AC voltage or current input and
provides an optically isolated DC voltage or current output that
is linearly related to the input.
The green LoopTracker
®
input LED provides a visual indication
that a signal is being sensed by the input circuitry of the mod-
ule. It also indicates the input signal strength by changing in
intensity as the process changes from minimum to maximum.
If the LED fails to illuminate, or fails to change in intensity as
the process changes, check the module power or signal input
wiring. Note that it may be difficult to see the LEDs under bright
lighting conditions.
The red LoopTracker output LED provides a visual indication
that the output signal is functioning. It becomes brighter as
the input and the corresponding output change from minimum
to maximum.
For current outputs, the red LED will only light if the output loop
current path is complete. For either current or voltage outputs,
failure to illuminate or a failure to change in intensity as the
process changes may indicate a problem with the module
power or signal output wiring.
