Description
The APD 1600 and 1620 accept an AC voltage or milliamp
current input and provide a visual alarm indication and alarm
relay contact outputs.
The input type, range, and alarm types are factory configured.
Front-accessible potentiometers are used to adjust alarm
setpoint and deadband.
LoopTracker and Alarm Status LEDs
API exclusive features include a LoopTracker LED that varies in
intensity with changes in the process input signal.
A red/green bi-color alarm status LED (two on the APD 1620)
visually indicate alarm status.
These LEDs provide a quick visual picture of your process at
all times.
Output Test / Unlatch
API's exclusive Output Test button can be used to verify the
alarm and system operation and also provides the additional
function of unlatching the alarm when the latching option has
been ordered. This feature can be remotely operated.
The output test button greatly aids in saving time during initial
startup and/or troubleshooting.

Installation and Setup APD 1600, APD 1620
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.
Electrical Connections
See wiring diagrams. If the module does not function, check
all wiring.
*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!
Input
The input range is factory pre-configured (at 24°C ±1°C). See
the model/serial number label for module information, input
type, input range and options. Connect the input as shown in
the wiring diagrams.
Alarm Types
Note that the deadband is symmetrical about the setpoint; relay
trip and reset points will both change if either the setpoint or
deadband are changed.
High Alarm (default, H, or HH): The alarm relay changes state
when the input exceeds the deadband trip point. The relay
resets when the input drops below the deadband reset point.
For a high alarm, the trip point is above the reset point.
Low Alarm (L or LL): The alarm relay changes state when the
input goes below the deadband trip point. The relay resets
when the input exceeds the deadband reset point. For a low
alarm the trip point is below the reset point.
HT: Latching alarm with push button reset
HP: Latching alarm with power-off reset. Module power must
be turned off to reset alarms
R: Reverse-acting alarms. Relay coils energized in an alarm
condition. No alarm condition with module power off.
Relay Output Terminals
See wiring diagrams below right for connections. APD modules
do not provide power to the relay contacts. Inductive loads
(motors, solenoids, contactors, etc.) will greatly shorten relay
contact life unless an appropriate RC snubber is installed.
The APD 1600 operates two sets of relays in unison with a
single setpoint. The dual SPDT contact sets are in a Form C
configuration.
The APD 1620 operates two sets of relays independently, each
with its own setpoint. The dual SPDT contact sets are in a Form
C configuration.
Module Power
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 upward until upper mount snaps into place.
Removal
1. Push up on the bottom back of the module.
2. Tiltfrontofmoduledownwardtoreleaseuppermountfromtop
edge of DIN rail.
3. The module can now be removed from the DIN rail.
Setpoint and Deadband Adjustments
Relay operation is factory configured. See model/serial number
label for relay configurations and options.
The Setpoint potentiometer allows the operator to adjust the
level at which the alarm is activated. This control is adjustable
from 0 to 100% of the input range.
The Deadband potentiometer allows the alarm trip and reset
window to be adjusted symmetrically about the setpoint from
1 to 100% of the span. This allows the operator to fine tune
the point at which the alarm trips and resets. The deadband is
typically used to prevent chattering of the relays or false trips
when the process signal is unstable or changes rapidly.
To calibrate the alarm section, set the deadband control to the
minimum (counterclockwise). The deadband will be 1.0% of
input span in this case.
Set the signal source to a reference that represents the desired
trip point.
Adjust the setpoint control to the point at which the relay
changes state from a non-alarm to an alarm condition.
If a larger amount of deadband is desired turn the deadband
potentiometer clockwise. The deadband is symmetrical about
the setpoint; both transition points will change as deadband
is increased.
Relay set and reset points will both change if the setpoint or
deadband are changed. Alternately set the setpoint and dead-
band until the desired trip and rest points are set.
Output Test Function
When the front test button is depressed it will drive the relays
to their opposite state. A customer-supplied switch connected
to terminal 4 and 8 can also be used to toggle the relays. When
released, the relays will return to their prior states.
This can be used as a diagnostic aid during initial start-up or
troubleshooting, or as a manual over-ride function. The Test
button also resets the relays on models with the HT option.
Operation
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 bi-color alarm LED provides a visual indication of the alarm
status. In all configurations, a green LED indicates a non-alarm
condition and a red LED indicates an alarm condition.
In the normal mode of operation, the relay coil is energized in
a non-alarm condition and de-energized in an alarm condition.
This will create an alarm condition if the module loses power.
For a normal acting, non-latching configuration, the alarm will
activate when the input signal exceeds the setpoint (HI alarm)
or falls below the setpoint (LO alarm), then will automatically
reset when the alarm condition no longer exists.
For a reverse acting alarm, the relay coil is de-energized in a
non-alarm condition and energized in an alarm condition. The
alarm activates when the input signal exceeds the setpoint (HI
alarm) or falls below the setpoint (LO alarm), then automatically
resets when the alarm condition no longer exists.
For models with the latching relay option, it will be necessary
to push the Test button or remove power from the module to
reset the alarm, depending on the type of latching option. The
alarm will only reset if the alarm condition no longer exists.
