Instructions

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.

API maintains a constant effort to upgrade and improve its products.

Specifications are subject to change without notice. See api-usa.com for

latest product information. Consult factory for your specific requirements.

WARNING: This product can expose you to chemicals includ-

ing nickel, which is known to the State of California to cause

cancer or birth defects or other reproductive harm. For more

Electrical Connections

Polarity must be observed for signal wiring connections. If the

input and/or output do not function, check wiring and polarity.

Each product is factory configured to your exact input and

output ranges as indicated on the serial number label.

Outputs

For milliamp ranges determine if your devices provide power

to the current loop or if the loop must be powered by the APD

module. Typical voltage may be 9-24 VDC at your device's

terminals if it provides power to the loop.

Module Power Terminals

Check label for module operating voltage to make sure it

matches available power. The power supplies are fuse protect-

ed and the unit may be returned to API for fuse replacement.

When using DC power, either polarity is acceptable, but for

consistency, wire positive (+) to terminal 25 and negative (–)

to terminal 28.

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 down and posi-

tion the lower spring clips against

the bottom edge of DIN rail.

2. Push front of module upward until

upper mount snaps into place.

Removal

Avoid shock hazards! Turn signal

input, output, and power off.

1. Push up on bottom back of mod-

ule.

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). Front-mounted Zero and Span potentiometers for

each channel can be used to compensate for load and lead

variations.

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 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

Terminal Terminal

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 ±10 V output.

4. Set the input at maximum, and then adjust the Span pot for

(+20 V)

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

initial start-up or troubleshooting. When released, the output

will return to normal.

Each Test Cal. potentiometer is factory set to approximately

50% output. Each 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 corresponding Test Cal. potentiometer for the

desired output level.

current outputs that are linearly related to the inputs.

each signal is being sensed by the input circuitry of the module.

They also indicates the input signal strength by changing in

intensity as the process changes from minimum to maximum.

If an 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.

Two red LoopTracker output LEDs provide a visual indication

that the output signals are functioning. They become brighter

as the input and each corresponding output change from

minimum to maximum.

For a current output 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.
