Description
The APD 1700 and APD 1720 accept a frequency input and
provides a visual alarm indication and alarm relay contact
outputs.
The input is factory configured to a specific frequency
input range. The input can be of any type as long as it has
a minimum of 100 mV amplitude change and a minimum 5
microsecond pulse width. Input sensitivity is potentiometer
adjustable.
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 bicolor alarm status LED (two on the APD 1720)
visually indicate alarm status. These LEDs provide a quick
visual picture of your process at all times.
Output Test / Unlatch
The API 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.
