Explanation of Signals:
Pin 1 Identical to Circular power input. Power must be applied via a Class 2
power supply.
Pin 2 Return path for Pin 1.
Pin 3 Analog 0-5 VDC Remote Control. The LED output responds linearly with
an applied signal to this pin. A 5V signal is maximum LED intensity.
Pin 4 Fault Output. This is an Open Collector output that is active when the light
source has a fault.
Pin 5 Signal Ground. Return path for pins 3 through 7.
Pin 6 Shutdown/Triggered Strobe signal. This signal turns the LED output on
and off in Normal Mode. The polarity of this signal is governed by the
Remote Polarity Switch. In Triggered/Strobe Mode, this signal should be
a trigger signal to activate a strobe pulse. The polarity of this signal in
Triggered/Strobe Mode is also governed by the Remote Polarity Switch. A
5-24VDC signal or contact closure can be used on this pin.
An Ethernet or RS-232 command toggles the function of this pin from LED
off to unit standby.
Pin 7 Convenient +5VDC output. The output current is limited to 1mA.
Pin 8 Chassis Ground. Connect this terminal to earth ground to ensure proper
grounding of the chassis.
To ensure protection against electric shock, connect only Class 2 power supplies
(double insulation) to pin1 and pin2 power pins.
To ensure EMC compliance, the chassis ground connection must be connected to
an earth ground or a ground connection made to the chassis PEM nut using a #6-32
screw and toothed lock washer.
Signal wiring to the Multi-Port terminal block (pins 3-8) must be rated for at least
200 mA, 30V. The power input wiring (pins 1 and 2) must be rated for at least 1.5
amps, 50V. The temperature rating of all wiring should be 70°C or greater. The
Phoenix Contact Terminal Block is rated for 16-28 AWG solid or stranded wire.
