Calibration
Input and output ranges as specified on your order are factory
pre-configured (at 24°C ±1°C). Top-mounted, Zero and Span
potentiometers can be used to calibrate the output to compen-
sate for load and lead variations.
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
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 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.
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 depressed it will drive the output with a known good
signal. When released, the output will return to normal.
The Test Range potentiometer is factory adjusted to approxi-
mately 50% of the output span. It can be field adjusted if
required.
Press and hold the Test button and adjust the potentiometer
for the desired output level. When released, the output will
return to normal.
Operation
The API 4400 G through API 4408 G are factory configured
series to your exact input and output requirements.
Up to four inputs can be scaled and connected to either addi-
tive or subtractive amplifier inputs according to the model
designation.
The input signal is filtered, and cancels any offset of the input
relative to the output. 50
Ω
shunts are used at the input for
current-to-voltage conversion if required.
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.
Precautions
WARNING! All wiring must be performed by a qualified electri-
cian or instrumentation engineer. See diagram for terminal
designations and wiring examples. Consult factory for assis-
tance.
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 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.
Socket and Mounting
Install module in a protective panel or enclosure. Allow space
around module for air flow. Use API 011 or API 011 FS socket.
See specifications for maximum allowable socket voltages. The
socket clips to a standard 35 mm DIN rail or can be mounted to
a flat surface.
Ranges
See the model/serial number label for module information,
module power requirements, options, and I/O range informa-
tion.
API 4400 G through API 4408 G input and output ranges are
factory configured as indicated on the serial number label.
Signal Inputs
Polarity must be observed when connecting the signal input.
Terminals 4, 5, 6, 7, 8 provide the appropriate connections for
the input signal. Polarity must be observed when connecting
the signal input.
The negative (–) connection for all inputs is connected to
terminal 5.
The positive (+) connection for input A is to terminal 4.
The positive (+) connection for input B is to terminal 6.
The positive (+) connection for input C is to terminal 7.
The positive (+) connection for input D is to terminal 8.
Signal Output
Polarity must be observed for output wiring connections. If the
output does not function, check wiring and polarity.
When a current output is ordered, it provides power to the
output current loop (sourcing).
Terminals 9 (+) and 10 (–) provide the connections for the
output. Note that the output provides power to the output loop.
Module Power
Check model/serial number label for module operating voltage
to make sure it matches available power.
AC power is connected to terminals 1 and 3.
For DC powered modules (D option), polarity MUST be observed.
Positive (+) is wired to terminal 1
Negative (–) is wired to terminal 3.
