Functions of the SIMATIC FS600 Laser Scanner
The SIMATIC FS600 Laser Scanner is equipped with the X1 and X2 interfaces. The
following functions are available through them:
7.1
Restart
Depending on the operating state, the restart input X1-2 has several functions:
•
Enables the restart interlock following the interruption of a detection zone
•
Enables the start interlock following a system start
•
Restarts after a device error has been eliminated
•
Recognizes a defined enable signal
-
after a device error
-
after a detection zone interruption for enabling the restart interlock
To activate the functions, apply 24 V to input X1-2. In the meantime, the safety outputs
OSSD 1 and OSSD 2 are switched off; the indicator at the scanner (LED3) is lit up red.
The duration of the signal must be between 0.12 s and 5 s.
The restart input X1-2 must be connected to an external, permanently installed button.
X1-2 must not be connected with the remaining controls in order to prevent an
unintended release with a Restart pulse under some circumstances.
Force-guided, normally closed contacts can be monitored in the restart circuit (relay
monitoring).
Please note the Chapter 5 (planning and mounting information) and 9.1 (electrical power
supply).
7.2
Channels for Zone Pair Changeovers, FP 1 to FP 4
To activate the zone pairs, apply +24 V (see Chapter 9.1) to the following inputs:
•
X1-4 (FP1)
•
X1-6 (FP2)
•
X1-7 (FP3)
•
X1-8 (FP4)
When changing over the zone pairs, please note that the new zone pair must be
switched on before the previous pair is switched off. The procedures is allowed to last a
maximum of 1 s. If this time period is exceeded, or if the previous zone pair is switched
off too soon, the SIMATIC FS600 Laser Scanner reports an error by switching off the
two OSSDs and the alarm output. In addition, this state is shown in the indicator field on
the scanner; flashing of left LED1 (slowly at 2 Hz), LED3 and right LED5 (fast at 4 Hz).
