Installation and Setup
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 remov-
ing or installing module.
Précautions
ATTENTION! Tout le câblage doit être effectué par un élec-
tricien ou ingénieur en instrumentation qualifié. Voir le dia-
gramme 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 connecter ou de déconnecter le câblage, ou de retirer ou
d'installer le module.

WARNING: This product can expose you to chemicals includ-
ing nickel, which are known to the State of California to cause
cancer or birth defects or other reproductive harm. For more

Range Selection
See table below to select I/O ranges for your application. It is
generally easier to select ranges before installation. See model/
serial number label for custom range settings if specified.
Electrical Connections
Polarity must be observed for input and output wiring connec-
tions. If the input and/or output do not function, check switch
settings and wiring 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!
Signal Output Terminals
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
Type of Device for Output
Measuring/recording device accepts a
voltage input. Switch C set to "V"
Measuring/recording device accepts a mA
(current) input and the input is unpowered
or passive. APD module provides the loop
power. Switch C set to "I"
Measuring/recording device accepts a mA
(current) input and provides power to the
current loop. Switch C set to "I"
Signal Input Terminals
The APD HV-DC accepts a DC voltage input. Polarity must be
observed when connecting the signal input.
DC Voltage Input
DC voltage negative
DC voltage positive
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
consistency with similar API products, positive (+) can be wired
to terminal 13 and negative (–) can be wired to terminal 16.

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.
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 up 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, if specified on your order, are factory
pre-configured (at 24°C ±1°C). Use the front-mounted Zero
and Span potentiometers to calibrate the output.
Note: Perform the following calibration procedure any time
switch settings are changed.
1. Apply power to the module and allow a minimum 30 minute
warm-up time.
2. Using an accurate calibration source, provide an input to the
module equal to the min. 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 cor-
responding minimum output signal. For example: 4 mA for
a 4-20 mA output or –10 V for a ±10V output.
4. Next, set the input 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 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.

The Test Cal. potentiometer can be used to set the test output
to the desired level. It is adjustable 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 HV-DC accepts a high-voltage DC voltage input and
Terminal
provides an optically isolated DC voltage or current output that

is linearly related to the input. The input is filtered and attenu-

ated as required, then passed through to the output stage.
Green LoopTracker
Provides a visual indication that a signal is being sensed by the
input circuitry of the module. 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, this may indicate a problem with module
power or signal input wiring.

Red LoopTracker output LED
Provides a visual indication that the output signal is function-
ing. 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.
