Using IDC Position Sensors as EOT Limit Switches with the Impulse

Four IDC position sensors m a y be used as EOT limit swit ches with the Impu lse. Co nnection

information for all four sensors is provided below.

•The PSR-2 position sensor is a nor-
mally closed Reed Switch and must be
connected to two (2) separate inputs, as
shown here. This leaves two (2) inputs
for move selects, which allows for the
selection of three (3) stored moves.
•The PSR-2 position sensor contains a
series diode and cannot be used in
series, as is the RPS-2 sensor shown
below.
Note: If you need to configure more
than 3 stored moves, the position sen-
sors be low only requ ire one input for
connection.

•The RPS-2 position sensor is a nor-

connec te d in series as shown here.
•The RPS-1 or PSR-1 position sensors
are normally open Reed Switc hes and
must be connected in parallel as shown
here.
