Controller Features

Modes of Operation
Time Clock
The controller will initiate a regeneration based upon a time schedule of intervals of days (i.e., every 3 days) or
on a specific day of week schedule (i.e., Mondays, Wednesdays and Saturdays). Because regeneration will
occur at the prescribed schedule regardless of water use, this method is usually the most inefficient method of
water softener operation.
Flow Meter/Sensor
When a flow meter or sensor is connected to the controller circuit board, the controller has the ability to measure
the amount of water treated and initiate a regeneration sequence based upon the gallon capacity of the water
treatment equipment. The controller can delay the regeneration signal until a convenient time of day (known as
a delayed regeneration) or act and initiate the regeneration sequence as soon as the signal is received (known
as immediate regeneration).
When installing an alternating duplex system (one tank on-line, the other in standby), only one flow measuring
device is required to be installed in the common outlet header of the system. Parallel systems (multiple tank sys-
tems, all on-line simultaneously) require one flow device for each mineral tank in the system.
This method is a proven, cost effective means to operate a water softening system.
Aqua-Sensor (Softener use only)
The Aqua-Sensor detects when a softener resin bed has reached its point of exhaustion and, as a result, initiate
a regeneration sequence. This is the most cost-effective method of operation and may be combined with any of
the operational modes previously described.
Progressive Flow
The Progressive Flow mode is used with up to six and as few as two mineral tanks in a system. It allows more
than one tank in a system to either be on-line or off-line depending upon the downstream flow demand. If flow
demand is greater than the flow capability of the tank on-line, another tank can be brought on-line to help satisfy
the excess demand. Once the demand has decreased, the second tank is returned to a standby mode and the
system reverts to just one tank on-line providing treated water.
The progressive flow mode of operation relies on a user programmable set point or Trip Point. The Trip Point
is a unit of flow (gallons or liters) on a per minute basis. Once attained the trip point will cause the second unit
(in multiple resin tank system) to come on-line. Each additional tank in the system will subsequently be brought
on-line as multiples of the trip point are attained. (Example: a 3 tank system with a trip point of 50 gpm will bring
two tanks on-line once the facility flow demands is equal to or greater than the 50 gpm trip point. Should the flow
demand reach 100 gpm or more, the third tank shall be brought on-line.)
Additional tanks shall be returned to stand-by once the facility flow demand is <95% of the trip point for two
tank systems, <95% of 2X the trip point for triplex systems and <95% of 3X the trip point for quad systems, and
remains there for 60 seconds.
Utilizing the progressive flow feature may allow the owner to use smaller units, resulting in the potential for
reduced capital and operation costs.
Differential Pressure (Filters only)
When combined with an optional differential pressure device, the Culligan MVP controller has the ability to
initiate a backwashing sequence when the pressure differential across the media bed reaches a preset amount
(usually 8 to 10 psi).

ELECTRICAL INSTALLATION
CAUTION!
Observe the precautions listed below before electrical installation of your GBE controller.
Failure to do so may cause permanent damage to the controller.
1. Follow the local electrical code requirements.
2. Be sure electrical power is off and disconnected at the source before completing any wiring/cabling
connections.
3. Provide a dedicated 120-volt circuit for the GBE system to ensure maximum electrical protection.
4. DO NOT include the GBE wiring cables in any conduit or raceway containing other 120-volt or higher
circuits.
5. Maintain a distance of at least 10 feet between the GBE controller and any electrical distribution
panels, raceways carrying 300 volts or more, and electrical motors of 1 horsepower or more.
6. Use the cabling provided. Failure to do so may effect performance of the GBE controller adversely.
Note: One transformer is required for each controller in the system. Do not attempt to operate multiple
controllers without a dedicated transformer for each or your system will experience operational
difficulties.

WIRING PROCEDURES AND DIAGRAMS
Preparation
1. Loosen the screws or latches securing the controller access cover (Figure 3 or 4) on each controller
provided.
2. Using a small screwdriver, loosen all the terminal strip binding screws on the main circuit board that do
not contain wires by turning counterclockwise until the wire clamp has been fully opened (see Figure 5).

Installation
Cable Routing
All input and output connections to the circuit board are 24 volt or less.
Although the cables do not have to be run in conduit, it is necessary that long runs of cable be supported or
protected by strapping them to the equipment piping. If conduit will be used to route the shielded cables, three
factors must be considered:
1. DO NOT share the same conduit or raceway with 120 volt or higher circuits.
2. Keep cables at least 6 inches away from 120 volt or higher electrical circuits.
3. GROUND the conduit (if metallic) to a known “earth ground” location.
A series of holes are located on the sides of the controller (see Figure 6 and 7). Strain relief fittings are provided
with the controller enclosure for interconnecting wiring. Install the plastic fittings as needed. Remove the com-
pression nut and rubber sleeve from each fitting. Prior to connection of the cable wires to the circuit board, slide
the compression nut and sleeve over the cable for the wiring connections. When wiring is completed, apply a
small amount of silicone to the rubber sleeve and reassemble. This will assure all wiring is secure and assist
in making the tightening of the fitting easier. Insert the plugs provided to block any holes not used for wiring or
other accessories.

will damage the circuit board.
Outputs
The circuit board supports four outputs:
• Motor control (DC Motor)
• Blocking valve (Use Aux Out 4)
• Four programmable auxiliary outputs (Aux Out 1
through 4)
• Controller interface (communication between mul-
tiple controllers) (RS485).
Note: If you are using Aqua-Sensor, you should run the 2.5v wiring now as the cable is run through the same cord grip.
See page 15 for details.
1. Locate the power cord among the controller parts. It has a white connector on one end and two spade connectors on the
other.
2. Locate the cord grip among the parts.
3. To assemble the power cord, first run the cord grip nut over the spade terminal end of the power cord.
4. Next, run the spade terminals through a hole in the side of the controller FROM THE INSIDE. See figure 10.
5. Finally, run the cable through the bottom end of the cord grip, and assemble the grip to the controller wall.
6. Plug the board connector to the board where it says “24v”. The connector has four (4) connections but only two wires are
connected. The other end of the power cord (with spade terminals) should be connected to the two 24VAC terminals on
the transformer (see figure 12).
DO NOT PLUG THE TRANSFORMER INTO THE WALL UNTIL ALL WIRING IS COMPLETED.
Repeat the process for any additional units in the system.

24V Transformer
The GBE control is powered by a 24V/50VA transformer. If there are multiple controls in the system being
installed, each control will require its own transformer. It is recommended that the transformer be plugged into a
dedicated 120V circuit.
CAUTION
Connecting 24V to the 2.5V connection on the circuit board will damage the circuit board
1. Connect one wire from the 24V cable to the outermost 24VAC transformer screw terminal
(Reference Figure 12). The other end of the wire should be connected to one of the 24V terminals
on the GBE control circuit board (Figure 11) by way of the white connector.
2. Repeat the process for the other 24V power supply wire attaching the second wire to the opposite
terminal on the transformer and next to the other wire connected to the 24V pins on the GBE board.

Aqua-Sensor Schematic (Optional)
The Aqua-Sensor device requires a 2.5 VAC power source. This source is provided via two of the posts on the
24VAC/2.5VAC transformer (see figure 20). The two leads from the transformer are run through the same cable
grip as the 24VAC and then must be pushed into the white power connector for connection to the 2.5v power
pins on the GBE circuit board.
The wire connector from the Aqua-Sensor probe is then routed through the included cable grip and plugged into
the Aqua-Sensor terminal on the GBE circuit board. See below.
Aqua-Sensor
If you are going to install an Aqua-Sensor, you can set up the 2.5V power now.
1. Locate the power cord packed with the Aqua-Sensor. It has two spade terminals on one end of the cable
and two metal “slip in” tabs on the other.
2. Locate the cord grip.
3. The cable can be run through the cable grip and wall from either end of the cable. Make sure the end with
the metal tabs goes INSIDE the controller. The spade terminals should be coming out the top end of the
grip.
4. Locate the connector at the end of the power cord. You may have already plugged it into the board.
5. Press the two metal tabs on the end of the power cord into the open slots on the connector. They will con-
nect to the pins labeled “2.5V’ on the Base Board.The other end of the power cord with the spade terminals
should be connected to the two 2.5VAC terminals on the transformer (see figure 20).
CAUTION - Verify wiring from terminals to circuit board are correct before applying power to
control. 24vac power must not be applied to the 2.5 vac terminals of the circuit board.

Auxiliary Input (Optional)
One auxiliary input is provided for optional signal devices such as remote push buttons, differential pressure
switches, hardness monitors, turbid meters, etc. for the purpose of receiving a regeneration signal.
Select an UN-POWERED contact within the remote device that will close when regeneration is desired. The
duration of the switch closure can be as low as 0 seconds; 6 seconds is the recommended minimum and default
but can be as long as 999 seconds. The contact must automatically open following the start of a regeneration
sequence. Connect this contact to the Aux In terminal shown in Figure 22. The illustration below is an example
