2. Verify that the Password Jumper is set to the OFF position. If the jumper
is in the ON position, reposition the jumper.
3. Check the position of the Failsafe Dip Switches. Position the dip
switches as shown in Figure B-3.
4. Check the position of the Source Current Dip Switches. Position the dip
switches as shown in Figure B-3.
5. Reinstall the SPA access cover.
Configuration/Calibration
Prior to operation, the SPA operating parameters must be configured via a
menu-driven setup procedure. At the end of the configuration procedure, the
SPA analog output signal is calibrated to insure valid communications.
1. See Figure B-4. Connect a calibrated ammeter (Fluke Model 87 or
equivalent, accurate to ±0.025%) to the SPA analog output terminals.
Observe polarity.
2. Connect a 90 to 260 VAC or 22 to 300 VDC power source to the SPA
power terminals. When connecting an AC power source, use the AC
and ACC (AC Common) terminals. For a DC source, use the AC and
Ground terminals.
3. If desired, you can connect the 4 to 20 mA O2 signal wires from the
OCX 8800 analog output terminal block to the SPA Input terminals. (The
OCX must be operational to transmit the O2 signal. Observe polarity.)
