Keyence FS-N11CP & FSN12CP Sensor Amplifiers
The
Keyence FS-N11CP
and
FS-N12CP
sensor amplifiers
(shown in Figure A.1 below) are used on the TM-400 Series
machines for the
Low Cover Tape Sensor
and the
Tape Jam
Sensor
. Both amplifiers are mounted on the
Cover Tape
Arm
. The
Low Cover Tape
amplifier (FS-N11CP) is located
on the left. The
Tape Jam
amplifier (FS-N12CP) is located
on the right.
The two amplifiers are designed to be attached electrically
and share power. Otherwise, the two units function indepen-
dently of one another.
Selecting the Output Mode
The FS-N11CP/FS-N12CP sensor-amplifiers can be set to two
Output
Modes
:
light-ON
or
dark-
ON
. This determines under what conditions the sensor is triggered and the
Operation Indicator
is
lit.
In
light-ON
mode, the sensor will be triggered when the current value (CV) of detected light from
the emitter is higher than the preset value (PV). In
dark-ON
mode, the sensor is triggered when
the CV of detected light is lower than the PV. Essentially, in
light-ON
Output Mode
the sensor
detects when an obstruction occurs (causing reflected light to increase) and in
dark-ON
Output
Mode
the sensor detects when an obstruction is removed (causing reflected light to decrease).
