Getting Started Teledyne API M701H High Performance Zero Air Generator
3-4 06712B (DCN5875)
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)
a. 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)
a. Connect a 1/4” diameter tubing to the water out fitting (refer to Figure 5-2) to
avoid the occasional spurts of water on the instrument rack. Connect the other
end of the tubing to a drain or, alternatively, the water can 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 AIR OUT port of the M701H 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 could be as high as 80 psig –see following cautionary note.
NOTE:
A pressure reading above 35 psig, with the exception of some specials set
to 50 psig, is a FAULT condition. Call Customer Service immediately.
b. Keep this line as short as possible to minimize pressure drops.
c. POWER. Connect the power cord to the proper power source.
At 115 VAC, 60 Hz, the M701H draws 12.7 Amps upon start-up.
At 230 VAC, 50 Hz, the M701H draws 6.5 Amps upon start-up.
Refer to Table 2-1 for additional power specifications.
CAUTION
ENSURE THAT THE POWER CORD IS PROPERLY GROUNDED .
