Keyence FS-N11CP & FSN12CP Sensor Amplifiers
The Keyence FS-N11CPand FS-N12CP sensor amplifiers
(shown in Figure A.1 below) are used on the TM-403 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.

Operation Indicator
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).
1.
Press the Output Selector button. The CV Indicator will display the current mode.
2.
Press the Manual button within 5 seconds of having pressed the Output Selector button.
The Output Mode will be toggled.
3.
The CV Indicator will return to its normal display after 5 seconds have elapsed.
