2.2 SPECTRUM-RAL Installation
2.2.1 Mount Enclosure
Mount the enclosure at an appropriate location using the two mounting holes accessible inside the enclosure. See
Figure 2. The location should be far enough upstream from the user that the sample air reaches the monitor before the
air reaches the user.
Figure 2: SPECTRUM-RAL Interior View
2.2.2 Air Supply
The male quick disconnect pneumatic connector on the regulator-flowmeter assembly is a Foster 3003 series. Plumb
the associated female connector into the airline. See Figure 1.
Connect the regulator-flowmeter and set the pressure at approximately:
20 PSIG and the flow at 1.0 SCFH or 0.5 lmin.
2.2.3 Relay Contacts
Relay contacts are accessible on a spring-clamp terminal strip inside the enclosure after removing the cover. Terminal
strip locations are listed in Table 1.

C 10
NC 11
NO 12
NOTE: Some versions of the SPECTRUM-RAL have two sets of relay contacts. If there is a second set of relay
contacts there will be 13 – 15 positions on the terminal strip. If present position 13=C, 14=NC and 15=NO.
Contact position refers to the unpowered condition that is also the alarm condition. Relay contacts are rated at 2 amps
@ 110V. Instrument ground is accessible at terminal strip locations 1, 2, and 3, and +12 VDC is available at locations
4, 5, and 6. When powering an auxiliary device with +12 VDC, do not overload the power supply (exceed 200 mA).
To exit relay wires, drill a hole in the lower right surface of the enclosure, and use a strain relief.
