PROBE EXPANSION PX-1000
The PX-1000 adds Temperature, pH and pH/ORP ports to the AquaController
system. It connects to the port labeled I/O on the Apex Base Module. Connect
Temperature, pH and ORP probes to the PX-1000 as needed. Power for the PX-
1000 is supplied by the included AC adapter. Only every 3
rd
PX-1000 needs a
power adapter. Before the Probe Expansion will be recognized, it needs to be
enabled on the Apex system as follows:
To enable/disable Probe Expansion:
Apex Display: System – Misc Setup – Probe Exp: Off – push the Select
button to toggle Probe Expansion on and off. The AquaController Apex must
be rebooted before this change takes effect. Either power cycle the Apex
Base Module (disconnect the AquaBus cable for 10 second and reconnect)
or see the section titled Restart the Apex (optional) for instructions on how
to restart the Apex.
Web Interface: This option is not available from the Web Interface.
Once the Probe Expansion is enabled, the PX-1000 should be automatically added
to the system. Up to 3 PX-1000 expansion modules can be daisy-chained
together off the I/O port. Each PX-1000 provides 6 digital inputs for float
switches, sensors, etc.
PX-1000 temperature, pH and ORP probes are enabled/disabled and calibrated
using the same menus and procedures as the Apex Base Module probes, see the
section titled Probe Setup for more information.
