Output
The table below indicated the state of the outputs. The indicator (on the transmitter) changes each time
the wait input (violet wire on the transmitter) turns ON. Output operation of the SL-V can be verified via
these indicators on the transmitter or monitoring the actual change of state on the outputs.
Pulse output through state information output 2
After the wait input turns ON eight times while I/O monitoring function is activated, the checking pulse is
output through the state information output 2. (If the connector cable used is for the NPN output, bar LED
No. 1 on the receiver begins to blink. If the connector cable used is for the PNP output, bar LED No. 2
begins to blink.)
The checking pulses can be output through state information output 2.
The number of checking pulses that can be output is as follows.
