Installation & Operation Instructions
AFP
GENERAL INFORMATION
The AFP allows an analog (voltage or current)
signal to control a
converts an analog signal into two relay contact
outputs (one increase/one decrease). The isolated
oating point output can be controlled by any one
of nine analog input signal ranges (using an o set
jumper). Upon power-up, the decrease relay will
drive 100% of the chosen timing range to ensure
that the output is at its minimum position. On a
loss of power, the output relays will be open and
no signal will be generated. The actuator will
remain at the last commanded position unless it
has "spring return". The AFP output rate of change
(sixteen ranges, in eight versions) is DIP switch
selectable.
MOUNTING INFORMATION
Circuit board may be mounted in any position. If
circuit board slides out of snap track, a
non-conductive "stop" may be required. Use only
ngers to remove board from snap track. Slide
out of snap track or push against side of snap
track and lift that side of the circuit board to
remove. Do not ex board. Use no tools.
WIRING INSTRUCTIONS
PRECAUTIONS
• Remove power before wiring. Never connect
or disconnect wiring with power applied.
• When using a shielded cable, ground the
shield only at the controller end. Grounding
both ends can cause a ground loop.
• It is recommended you use an isolated
UL-listed class 2 transformer when powering
the unit with 24 VAC. Failure to wire the
devices with the correct polarity when sharing
transformers may result in damage to any
device powered by the shared transformer.
• If the 24 VDC or 24VAC power is shared with
devices that have coils such as relays,
solenoids, or other inductors, each coil must
have an MOV, DC/AC Transorb, Transient
Voltage Suppressor (ACI Part: 142583), or
diode placed across the coil or inductor. The
cathode, or banded side of the DC Transorb or
diode, connects to the positive side of the
power supply. Without these snubbers, coils
produce very large voltage spikes when
de-energizing that can cause malfunction or
destruction of electronic circuits.
• All wiring must comply with all local and
National Electric Codes.
