Product description
Features
The FYQLA1-140R-3 is a category 3 PL d( ISO 13849-1:2015) logic amplier.
The basic features of the FYQLA1-140R-3 include inputs for up to six individual
two-channel switches for monitoring door access or guarded/monitored functions.
Both channels are monitored and cross checked for proper operational switch
states. The safety function monitors all switches, and they must have closed state
conditions on both channels to allow the safety relay output to be energized.
• Monitored inputs (6)
• N.O. output relay contact
• Internal relay monitoring
• Screw terminals
• LED input indicators
• LED fault indicator
• LED relay status indicators
• LED relay power indicator
Together with the 50FY41 series sensors and 52FY31 series actuators, the
FYQLA1-140R-3 can be used to protect one or more points of hazardous areas.
Functions
Power-up sequence
After power is applied to the system, an internal system check is performed
verifying the functional logic and connected switch conditions. If any errors are
detected at power-up, the safety output relays will remain in the de-energized
state. Time to complete this internal verication is approximately two to three
seconds.
Power-up state (output relay energized):
• All internal function checks were veried and all input switch states are in the
closed position
Power-up state safety function (output relay de-energized):
• All internal function checks were veried, but one or more input switch states
are in the open position
• One or more internal function checks fail

System inputs
The six device inputs allow the user to monitor up to six functional switch devices.
Each device must have two channels of output, one sourcing output and one
sinking output. These outputs must operate in tandem for a valid switch function
to be recognized by the FYQLA1-140R-3. If the output channels of the switches are
not functioning in a synchronized manner the amplier will not accept the switch
closure as a valid. The allowable timing between closure of switch channel A and
channel B is approximately one second. If any given pair of switch channels does
not transition to the proper state in the minimum time, then the monitor will issue a
fault on that switch channel and prevent the output from closing.
Reset faulted state
If an invalid door switch sequence is detected by the Channel A and Channel B
synchronization, the output safety relays will open and red fault LED will blink.
Reset is accomplished by a power down/power up sequence.

Attention
Ensure the alignment of the sensor and magnetic actuator are correct
for proper operation. A 10 mm (0.39 in) separation distance between
sensor and actuator will cause an OFF condition, independent of axial
oset distance.
Sensor cable length must not exceed 25 m (80 ft).

Fault diagnosis
If fault LED ashes and no sensor alignment problem can be found:
• Turn o power
• Unwire sensors from input terminals
• Power up unit
•
If fault LED begins to ash repeatedly after 2-3 seconds, the system needs to be
replaced. If the fault LEDs do not begin to ash:
• Remove power, then wire one sensor (R,W,B,O) connection at a time. Apply
power, waiting 2-3 seconds. Repeat sequence with all sensors until fault
LED begins to ash. This will be the sensor/actuator that is generating
the fault condition. Reevaluate alignment and terminal connections. If no
problem is found, replace the sensor and/or actuator in question

*The following assumptions were made during the failure modes, eects, and diagnostic analysis (FMEDA) of the
FYQLA1-140R-3:
• Failure rates are constant, wear out mechanisms are not included.
• Failure rates are based on the Siemens standard SN29500.
• Power supply failures are not included in the FMEDA, a loss of power introduces the safe state.
• It was assumed that the appearance of a safe error (e. g., output in safe state) would be repaired within 8
hours (e. g., remove sensor burnout).
• During the absence of the device for repairing, measures have to be taken to ensure the safety function (for
example: substitution by an equivalent device).
• The stress levels are average for an industrial environment and can be compared to the Ground Fixed
Classication of MIL-HDBK-217F. Alternatively, the assumed environment is similar to IEC 60654-1 Class C
(sheltered location) with temperature limits within the manufacturer’s rating and an average temperature over
a long period of time of 40 °C. Humidity levels are assumed within manufacturer’s rating. For a higher average
temperature of 60 °C, the failure rates should be multiplied with an experience based factor of 2.5. A similar
multiplier should be used if frequent temperature uctuation must be assumed.
