Precautions
WARNING! All wiring must be performed by a qualified electrician
or instrumentation engineer. See diagram for terminal designa-
tions and wiring examples. Consult factory for assistance.
WARNING! Avoid shock hazards! Turn signal input, output, and
power off before connecting or disconnecting wiring, or removing
or installing module.
Précautions
ATTENTION! Tout le câblage doit être effectué par un électricien
ou ingénieur en instrumentation qualifié. Voir le diagramme pour
désignations des bornes et des exemples de câblage. Consulter
l'usine pour assistance.
ATTENTION! Éviter les risques de choc! Fermez le signal d'entrée,
le signal de sortie et l'alimentation électrique avant de con-
necter ou de déconnecter le câblage, ou de retirer ou d'installer
le module.

Ranges
See the model/serial number label for module information,
options, and I/O range information.
Electrical Connections
See wiring diagrams. Observe polarity. If the output does not func-
tion, check all wiring and polarity.
*
Do not make any connections to unused terminals or use them
as wiring junctions for external devices. This may cause permanent
damage to the module!
Inputs
Polarity must be observed when connecting the signal inputs.
Inputs may each be different ranges and types.
For a transmitter with a current output, it must provide power to
the current loop. This is typically a 3- or 4-wire device, or a passive
transmitter with a loop power supply. Use a multi-meter to check
for voltage at the transmitter output terminals. Typical voltage may
be in the range of 9 to 24 VDC.

Output
Polarity must be observed when connecting the signal output.
If your device requires a current input, determine if it provides
power to the current loop or if it must be powered by the APD
module. Use a multi-meter to check for voltage at the input
terminals. Typical voltage may be in the range of 9 to 24 VDC.

Module Power Terminals
Check model/serial number label for module operating voltage to
make sure it matches available power.
When using DC power, either polarity is acceptable, but for con-
sistency with similar API products, positive (+) can be wired to
terminal 13 and negative (–) can be wired to terminal 16.
The power supplies are fuse protected and the unit may be
returned to API for fuse replacement.

Mounting to a DIN Rail
Install module vertically on a 35 mm DIN rail in a protective enclo-
sure away from heat sources. Do not block air flow. Allow 1" (25
mm) above and below housing vents for air circulation.
1. Tilt front of module downward and position against DIN rail.
2. Clip lower mount to bottom edge of DIN rail.
3. Push front of module upward until upper mount snaps into place.
Removal
1. Push up on the bottom back of the 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 are factory pre-configured (at 24°C ±1°C).
Use the front-mounted Zero and Span potentiometers to calibrate
the output.
1. Apply power to the module and allow a minimum 20 minute
warm up time.
2. Using an accurate calibration source, provide an input to each
channel equal to the minimum input required for the applica-
tion.
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 ±10 V output.
4. Next, set all of the inputs at maximum, then adjust the Span
pot for the exact maximum output desired. The Span control
should only be adjusted when the input signal is at its maxi-
mum. 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
The test button may be used to drive the device on the output (a
panel meter, chart recorder, etc.) with a known good signal that
can be used as a system diagnostic aid during initial start-up or
during troubleshooting.
When pressed it will drive the output with a known good signal.
– Terminal
When pressed again, the output will return to normal.
6 (–)
The Test Cal. potentiometer can be used to set the test output to
8 (–)
the desired level. It is factory set to provide approximately 50%
10 (–)
output. It is adjustable from 0 to 100% of the output span.
12 (–)
Push the Test button to enable the output test and adjust the Test
Cal. potentiometer for the desired output level. Press the button
again and the output will return to normal.
Operation
The APD 44xx is factory configured to your exact input and output
requirements. Each input is filtered, either amplified or attenuated
as required, then passed through to the output stage.
The output level is determined by the levels of inputs and the math
+ Terminal
function depending on the model.

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 LED under bright lighting
conditions.
