II. Description
Control Functions
Each of the control functions is based on an analog input from a probe and will include user settable relay
control settings along with a High and Low Alarm setting and Limit Timer. Each control function will include
a control relay output. When the reading reaches the Set Point the control relay is activated until the
readingchangesbytheDi󰀨erentialamount.
1. Conductivity - The conductivity function of the controller is designed to monitor and control
Total Dissolved Solids (TDS) in a recirculating system like a cooling tower in terms of electrical
conductivity measured in MicroSiemens/cm. This control function is also referred to as bleed. Units
with conductivity and the make-up conductivity function can control the TDS of the tower system
toacyclesofconcentrationbycalculatingthedi󰀨erencebetweentheincomingmake-upwater’s
conductivityandthesystem’sconductivity
2. pH - The pH function monitors and controls pH on a scale of 0-14 pH units.
3. ORP - The ORP function monitors and controls ORP on a scale of +/- 999 mV.
Chemical Feed Timers
Selectable Chemical feed timers (base function F) are designed to automate the addition of various
chemicals by activating a relay output. Multiple timers can be supplied depending upon the model number
and each timer will include a relay output. All timers can be programmed to be one of the following types.
1. Pulse Time - This timer accepts dry contact pulses from a make-up water meter (supplied
separately). It can accumulate 1-99 pulses to activate the timer to run from 0-99 minutes in minutes
and seconds.
2. Feed with Bleed - This timer activates the relay output simultaneously with the bleed. The timer
can limit the amount of time the relay output will be on during the bleed cycle, thereby preventing
chemical overfeed.
3. Feed after Bleed-Thistimeractivatestherelayoutputbasedonauserdenedpercentageof
thebleedo󰀨time.Therelayisactivatedafterableedcycleandrunsforthesetpercentageofthat
bleed cycle. A limit time can also be set for the maximum amount of time the timer can run for one
cycle.
4. Percentage - The relay is on for a percentage of a continuously repeating cycle time. The percentage
timer can be set from 1 to 99% and the cycle time can be set from 1 second to 99 minutes and 59
seconds.
28-Day Feed Timers
28-day feed timers, typically used for biocide feed are based on a 28 day cycle with two independent
programmable feed cycles allowing for feed on selectable days and weeks. The biocide timers also
include prebleed and bleed lockout settings. Multiple timers can be supplied depending upon the model
number and each timer will include a relay output.

III. Installation
Electrical Wiring
The standard MicroTron Tower controller has an internal regulated power supply that will operate in the range
of approximately 100 to 240 VAC on the incoming wiring. Output relay(s) are protected with a replaceable
fuse.Eachrelay’soutputvoltagewillequalincominglinevoltage.
Prewired units are supplied with a 16 AWG cable with 3-wire grounded USA 115 volt plug for incoming power
and 18 AWG 3-wire grounded U.S.A. 120 volt receptacle cords for all control relay outputs.
Conduit units are supplied with connectors located in the lower section of the controller. Remove the screws
of the lower panel for access and to view wiring diagram.
NOTE: Liquid tight ttings and labeled signal lead cables are provided for all signal (low voltage)
connections, such as water meter, low drum level, ow switch and 4-20mA outputs, for both pre-wired
and conduit units.
Mounting Instructions
Select a mounting location that provides the operator easy access to the unit and a clear view of the controls
through the cover of the controller. The location should be convenient to grounded electrical connections, the
requiredsamplelineplumbing,andinstalledonastableverticalsurface.
CAUTION
1. There are live circuits inside the controller even when the power switch on the front panel is in
the OFF position. Never open the front panel without rst disconnecting power from the outlet.
Prewired controllers are supplied with an 8 foot, 18 AWG power cord with USA style plug. A #1
Phillips driver is required to open the front panel.
2. Low voltage signal wires (probes, ow switch, water meter, etc.) should never be run
in conduit with high voltage (like 115VAC) wires.
3. Never attempt to land connections to the controller without rst disconnecting power from the outlet.
4. Do not block access to disconnect power during mounting and installation.
5. The controller should be connected to its own isolated circuit breaker, and for best
results, the ground should be a true earth ground, not shared. Any attempt to bypass the grounding
will compromise the safety of users and property.
6. The electrical installation of the controller must be performed by trained personnel only and
conform to all applicable National, State and Local codes.
7. Operation of this product in a manner not specied by Advantage Controls may result in damage
to equipment or persons.
8. Avoid mounting in locations that expose the controller to direct sunlight, vapors, vibration,
liquid spills or extreme temperatures; less than 0°F (-17.8°C) or greater than 120°F (50°C).
EMI(electromagnetic interference) from radio transmissions and electric motors can also cause
damage or interference and should be avoided.
