Adjustments
Manual Override (XEC-3004 Only)
1. Move the “MAN/AUTO” jumper from “AUTO”
to “MAN.” (See the illustration on page 1.)
2. Adjust the potentiometer for desired output by
observing gauge or the 1–5 VDC output signal.
Span and Zero
The “Span and “Zero” adjustments are factory-set
and should never need adjusting. On boards manu-
factured before Nov. 2009 (only), this calibration may
be adjusted slightly as follows:
1. Disconnect the main air.
2. Adjust the “ZERO” potentiometer to 0.1 VDC
feedback output.
3. Reconnect the main air.
4. Apply an input voltage of 5.1 or 10.2 VDC or
input current of 20.4 mA.
5. Adjust the “SPAN” potentiometer for 15 psi
branch output pressure.
6. Apply an input voltage of 3 or 6 VDC or input
current of 12 mA.
7. Readjust the “ZERO” potentiometer for 9 psi.
Maintenance
No routine maintenance is required. Each compo-
nent is designed for dependable, long-term reliabil-
ity, and performance. Careful installation will also
ensure long-term reliability and performance.
CAUTION
Pneumatic devices must be supplied with clean, dry
control air. Any other medium (e.g., oil or moisture
contamination) will cause the device to fail.
