DELTANET R7515A/B, RP7515A/B, R7516B MICROCEL
™
CONTROLLERS
�
The R7515B and R7516B have a microbridge airflow
sensor but not the base unit board assembly, and are
used for remote airflow measurement.
�
Cases are in three sizes as follows:
— The small case (Fig. 2) accommodates a
MicroCel with base board only or a base board
and one input board.
— The standard case (Fig. 3) accommodates a
MicroCel with a base board, one input board, and
one output board.
— The large case (Fig. 4) accommodates a
MicroCel with a base board, two input boards,
and one output board.
INSTALLATION
Mount the MicroCel in a location that allows clearance for
cover removal, wiring, and servicing. See Figures 2, 3, and 4
for dimensions and other details.
CAUTION
For MicroCels with integral pneumatic transducers,
mount the MicroCel in a vertical position so that the
transducers will be oriented toward the bottom of the
case and below the MicroCel PC boards. This position
prevents damage from condensation possible from
main air.
