 Smartscan Non-Safety Light Grid N Series: Controls Information

N Series: Controls Diagram
Transmitter  ON: A yellow LED at the transmitter column illuminates indicating that the unit is powered-up. 


Receiver ON: A yellow LED ON at the receiver column illuminates indicating that the unit is powered-up. 


Output ON: Green LED indicator at the receiver unit illuminates when the electronic output (clear)is ‘ON’ (only when the light grids detection zone is ‘clear’ of any obstruction).

Output OFF:  Red LED indicator in the RX unit illuminates when the electronic output (blocked) is 'ON'. Only when the light curtains detection zone is obstructed or 'blocked'.

Clear Output Signal: Output ‘ON’ = 24V DC, Output ‘OFF’ = No Voltage. Maximum switching current for this output = 24V DC, 200mA.  The black wire.

Blocked Output Signal: Output ‘ON’ = 0V DC, Output 'OFF' = No Voltage. Maximum switching current  this output = 24V DC, 200mA.  The white wire

Power Supply: A regulated power supply is required: +24V DC, up to 1.5A dependent on OSSD loads ±10%. Cable colors for power supply connections at both transmitter and receiver:  Brown wire = +24V DC, Blue wire = 0V DC.

A 24V DC regulated power supply should be used for connection to the transmitter and receiver units. The transmitter and receiver units operate entirely independently from each other, e.g. there are no electrical connections between the transmitter and receiver units therefore separate 24V DC power supplies may be used if required.
