GETTING STARTED Teledyne API Model 701 Zero Air Generator
3-4 01671H (DCN6051)
3.4 Electrical And Pneumatic Connections All connections, electric and pneumatic, are made at the rear panel (Figure 3-3).
NOTE
To maintain compliance with EMC standards, it is required that the cable length be
no greater than 3 meters for all I/O connections, which include Analog In, Analog
Out, Status Out, Control In, Ethernet/LAN, USB, RS-232, and RS-485.
Make the following pneumatic connections:
1. “AIR IN” (1/4” female pipe thread):
Screw the inlet filter into the “AIR IN” port. Hand-tight is OK.
NOTE
Operation without the filter will cause premature pump wear.
2. “DRAIN” (1/4” swage-type bulkhead union):
Connect 1/4” diameter tubing to the water DRAIN fitting to conduct the occasional
spurts of water away from the instrument rack. Connect the tubing to a drain or,
alternatively, the water may be collected in a tray or bucket and dispersed by normal
evaporation
3. “ZERO AIR OUT” (1/4” swage-type bulkhead union):
a. Connect the ZERO AIR OUT port of the M701 to the INLET fitting of the Model
700 Calibrator with CLEAN 1/4” TFE tubing. The pressure in this line will normally
be 30 PSIG, but may be as high as 80 psig.
b. Keep this line as short as possible to minimize pressure drops.
4. “POWER”:
Connect the power cord to the proper power source.
At 115 VAC, 60 Hz, the M701 draws 3.5 Amps.
At 230 VAC, 50 Hz, the M701 draws 2.0 Amps.
.
WARNING
Be sure that the power cord is properly grounded
5. “COOLING FAN”:
The rear panel cooling fan draws air IN and requires at least 6” (150 mm) of
clearance for proper operation.
