Power Supply
Use a regulated power 24V DC ±10% fused at 2A. The T4 (053B) series
light curtain current consumption is rated at 1.5A. The White wire on both the
Transmitter (TX) and Receiver (RX) head cables must be connected to 24V DC
(L+). The Brown wire on both the Transmitter (TX) and Receiver (RX) head
cables must be connected to 0V DC (L-).
Before the power supply is applied to the light curtain ensure both TX and RX
heads are aligned correctly. On power up the PWR LED on the Transmitter (TX)
head will turn on to indicate power is connected.
If during set-up LED LO1 and LO2 start to flash alternately this is due to the
Transmitter (TX) head cable not being connected.
If the Power LED starts to flash during set-up the Receiver (RX) head cable is not
connected.
Warning Do not disconnect the cables from the Transmitter (TX) or
Receiver (RX) head with the power still connected to the T4 (053B)
series light curtain.
Any wiring or re-wiring of the light curtain must be done with the power
supply disconnected.
Any input or output signals that are not being used must be terminated
to an individual isolated terminal block.
The machine must be disconnected during electrical installation to
ensure no inadvertent start-up of the machine occurs.
The connection cables must not be routed with high-voltage cables,
e.g. inverter cables or motor power supplies.
Warning 0V (L-) of the power supply unit (PSU) must be connected
to ground. No signal should 24V DC ±10% (L+) or be less than
0V (L-)
Warning The shield on both the Transmitter (TX) and Receiver (RX)
head cables must be connected to Earth (PE).
