CS510 OxyGuard Dissolved Oxygen Probe
5
Optional Repeat Cycle Timer for Agitators
: Reciprocating action may be
controlled by the optional solid state Repeat Cycle Timer. It sends 12 VDC pulses
to the agitator coil. The ON-time is 0.25 sec. The OFF-time is adjustable from 3
to 12 sec.; requires supply voltage 10 to 17 VDC; housed in watertight cylinder
6.6" x 2" diameter (170 mm X 50 mm).
6. Application Information
Short Cut users: This application note was written primarily for
those whose needs are not met by Short Cut. Your procedure is
much simpler: just add the OxyGuard probe (it’s in the water
quality sensor group), save your program, and follow the wiring
shown in Step 4 of Short Cut.
7. Wiring
The OxyGuard probe uses one differential channel. Differential wiring is better
at rejecting electrical noise and ground loop error.

8. Programming
Instruction 2, differential millivolt measurement is required for the OxyGuard
probe. The example measurement instructions that follow do not store data to
final storage. Additional instructions (Typically P92, P77 and output processing
instructions such as P70) are required to store data permanently.

9. Calibration
The multiplier is used to calibrate the OxyGuard probe. To calculate the
multiplier:
1) Program the CR10(X) using a multiplier of one.
2) Place the OxyGuard probe in the air, shaded from the sun. Wait for readings
to stabilize. This may take 15 minutes or more.
