3.8. External interlock connection
External interlock pins are provided for the customer’s use (see Section 4 for connection details). Any
suitable normally-open contact or solid-state switch can operate the interlock circuit. The contact or switch
should be rated for 8mA minimum at 5VDC.
The interlock circuit must be connected to enable the operation of the unit. Should the interlock connection
open during operation or standby, the source is immediately disabled, and all light output from the aperture
ceases.
4. TLS-EQ-77H Setup
4.1. Connections
Installation of the TLS-EQ-77H consists of connecting electrical, water, and purge gas supplies, and
connecting the Lamp House module to the user’s equipment. Read "Installation Procedure" first before
making any connections.
4.1.1 Electrical Power
The TLS-EQ-77H requires 100 – 240 V~, 50/60 Hz input voltage. Power consumption is 350 W maximum
during normal operation. Some OEM versions have higher current requirements.
4.1.2 Purge Gas
Purge gas required for operation. With no purge, ozone will form from atmospheric oxygen and attenuate
the light output in the 220 – 280nm band. In addition, atmospheric oxygen and water vapor will attenuate
the output below 200nm.
The purge port fitting is a push-to-connect type, sized for 4mm O.D. tubing.
Clean and dry nitrogen from either a Dewar or research-grade N
2
bottle is recommended. Do not use any
other purge gas. Grade 6 or better gas purity is recommended to maintain cleanliness of the optics, and
gas should be filtered to <5um. Supply pressure should be 20 psig (0.14 MPa). With a 20 psig inlet
pressure, the EQ-77 will consume approximately 0.5 slm of flow.
4.1.3 RS-485 Interface
Connector J2 is a standard 9-pin male d-sub. Mating connector is a standard 9-pin female d-sub (for
example, AMP part no. 205203-3 with contacts 1-66504-0). See Section 10.4 for pin connections.
Port settings are 9600 bps, 8 data bits, 1 stop bit, no parity, no handshaking.
