Offboard Air Module Wiring.
CAUTION
The LCM-OAVS has two terminal
blocks with terminations numbered
identically (terminations 1 through
16). DO NOT get these mixed up
with each other.
If the LCM-OAVS is not connected
as shown, it is not resistant to
electrical surges. It is also
susceptible to interference from
other equipment.
CAUTION
A separate power supply is required
if a 4-20 mA sensor is used.
Failure to follow wiring precautions
will result in equipment damage.
Wiring for AI with a 4 to 20 mA Sensor.
CAUTION
Each 4-20 mA sensor requires a
SEPARATE dedicated power limited
24 Vdc power supply.
DO NOT use the same transformer
to power both the sensor and the
controller.
NOTE:
If the voltage/current switch is set to
current and a 4 to 20 mA sensor is
connected to an AI, then special wiring
requirements must be followed.
NOTE:
When wiring any actuator that uses a 0 to
10V control signal and ties AC neutral to DC
common, an additional wire must connect
the actuator AC neutral to the DC common
of the PTEC/TEC AO being used to control
the actuator.
