limit, the audible alarm will be activated and the ORP feed output will be disabled. The alarm will
be cleared and feed will resume automatically when the measured ORP value returns to within the
non-alarm range.
525: Use the UP and DOWN buttons to select a value between 200 and 995 pH. The value
must be less than the pH alarm high value. The default value is 525 mV.
r.AD (Remote Alarm Delay)
When using a remote alarm connected to the Alarm Output relay, you can select a delay time
between 0 and 10 minutes.
0: Use the UP and DOWN buttons to select a value between 0 and 10. The default value is 0.
O.AH (ORP Alarm High Limit)
Sets the high alarm point for the ORP channel. When the measured ORP value is greater than this
limit, the audible alarm will be activated and the ORP feed output will be disabled. The alarm will
be cleared and feed will resume automatically when the measured ORP value returns to within the
non-alarm range.
900: Use the UP and DOWN buttons to select a value between 400 and 995. The value must
be greater than the ORP alarm low value. The default value is 900 mV.

Srl (Serial Interface)
The CAT 2000 includes a standard Rs232 serial interface. A header assembly and cable are
required to connect.
Onl: Online Communications. Use this selection when the controller is attached to a PC or
building automation system.
Prn: Printer. Use this selection when the controller is attached to a CAT Serial Printer to
make a hard-copy record of controller operating parameters. The printer is supplied with a
cable to connect it to the controller. The CAT Serial Printer prints one data record at 15 min-
ute intervals. Data recorded includes pH and ORP measured values, and the feed output and
alarm status of both channels. This is the default setting.
When all desired settings have been entered, press the Hidden Button or wait 30 seconds and the
controller will return to default operating mode.
