LOGIX™SERIES INSTALLER QUICK-START SHEET
LOGIX SERIES CONTROLLERS
740 Controller - Electronic time clock control capable of doing 7-day (day of
week) regeneration, or up to a 99 interval day regeneration. This control will
operate both in a conditioner (softener) or 3-cycle filter mode with the same
controller.
760 Controller - Electronic metered-demand (volumetric) controller which
regenerates based on the water usage of the installation site. A calendar
override is a standard feature on this controller.
The Logix Series will operate on both the 255 and Performa valve body series.
INITIAL POWER-UP
Initial Power Up - (CAMSHAFT proceeds to HOME position)
• At initial power-up, the camshaft will need to rotate to the HOME
(in service) position.
• Camshaft may take 1-2 minutes to return to home position.
• Err 3 will be displayed until the camshaft returns to home.
• If more than 2 minutes elapses, verify that the motor is turning the
camshaft. If it is not turning, see the troubleshooting section in Dealer
Installation and Service Manual.
INITIAL START-UP STEP-BY-STEP INSTRUCTIONS
Step 1: Program System Size
This step may have been performed by your system’s OEM manufacturer. In
this case, proceed to step 2
•Input tank diameter sizein inch (7-8-9-10-11-12-13-14-16).
•Use UP and DOWN buttons to scroll diameter choices.
•"11" value corresponds to 10x44 and 10x54 tank sizes.
• To choose a 3-cycle filter operation - press DOWN until an "F" is displayed.
• Press SET to accept the system size you’ve selected.

Step 7: Estimated Capacity
•System capacity is displayed in total kilograms ofCaCO3removed
before a regeneration is necessary.
•Value is derived from the system’ssize input, and L-S-H salt amount input.
•The capacity displayed is a suggested value.
• Capacity is only displayed for information purposes on 740 control - it does not (and
cannot) need to be changed.
• To change capacity on 760 control, press SET to make the default capacity flash. Use
the UP and DOWN buttons to increment to the desired capacity.
• Press SET to accept the setting and advance to the next parameter.
If using 740 control, programming is complete. The control will return you to the normal

• C3 - Slow Rinse (not used in filter mode)
• C4 - System Pause (to repressurize tank)
• C5 - Fast rinse cycle 1
• C6 - Backwash cycle 2 (not used in filter mode)
• C7 - Fast Rinse cycle 2 (not used in filter mode)
• C8 - Regenerant refill (not used in filter mode)

Logix™ Chlorine Generator (Check Salt Light)
Installation Instructions
The Logix 740C/742C and 760C/762C controls
have the capability to command a device
for chlorine production (optional) to disinfect the
resin bed at every regeneration.
There is a check salt light which indicates
when the salt finishes.
Potassium chloride or sodium
chloride may be used. Installing the chlorine
generator is simple.
Step 1
Remove the Logix control from the valve and
disconnect power.
Step 2
Connect the chord to the plug
on the back of the Logix control
at the connection labeled "Chlorine Generator
Outlet 740C/742C and 760C/762C."
Step 3
Remove the existing refill controller
from the valve and replace it with the chlorine
generator refill flow control. See the illustrations
to the right for the location of the refill controller.
Step 4
Insert the large connector of the chlorine
generator chord to the end of the refill flow
control. Press it in firmly to make sure there is
good contact.
Step 5
Reconnect power to the Logix Control and
reinstall the control to the valve.
No programming is necessary for the chlorine
generator to work properly. After the chlorine
generator senses regenerant for the first time it
will be functional. There is a check salt light on
the front of the Logix control that will illuminate
when there is no regenerant present during the
regenerant draw.
