FIGURE 4-2. CS512 with PT4 Agitator
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).
5. Application Information
SCWin users: This manual was written primarily for those
whose needs are not met by SCWin. Your procedure is much
simpler: just add the CS512 probe (it’s in the water folder), save
your program, and follow the wiring shown in Step 2 of SCWIN.
6. Wiring
The CS512 probe can use one differential channel or one single-ended channel.
Differential wiring is better at rejecting electrical noise and ground loop error.
