I. Introduction
MicroTron controllers are microprocessor based menu driven units for control of recirculating water applications.
All settings are entered into the controller through a simple front panel keypad which includes relay test
keys.
Model Numbering
Base Functions
All model numbers can be broken down as
follows and will start with an M or L:
MMicroTron with a VFD display
L MicroTron with an LCD display
FSingle programmable feed timer
F-2 Dual feed timers
F-3 Triple feed timers
F-4 Quadruple feed timers
BSingle 28 day timer
B-2 Dual 28 day timers
B-3 Triple 28 day timers
II. Description
Selectable Timers
Selectable timers (base function F) are designed to automate the addition of various chemicals or activation
of other devices via 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 Timer – This timer accepts dry contact pulses from a make-up water meter (supplied
separately). It can accumulate 1-250 pulses to activate the timer to run from 0-99 minutes, 59
seconds in minutes and seconds.
2. Percentage – The relay is on for a percentage of a continuously repeating cycle time. Both the
percentage and cycle time are programmable.
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 on units
with selectable timers also include bleed lockout settings. Multiple timers can be supplied depending upon
the model number, and each timer will include a relay output.
MicroTron timer controllers have several base functions and optional features available. Your unit may be
supplied with one or more of the options that are described in this manual. To determine what features apply
to your unit, check the model number label located on the controller enclosure.
Optional Features
This list represents our most popular options.
A Conduit connections
A-6 On/Off power switch
A-7 Lower enclosure
D220 V service (conduit only)

III. Installation
Electrical Wiring
The standard MicroTron Timer controller has an internal regulated power supply that will operate in the range
of approximately 90 to 240 VAC on the incoming wiring. Output relay(s) are protected with a replaceable fuse.
Relay output voltage will equal the incoming line voltage.
Prewired units are supplied with a 16 AWG cable with a 3-wire grounded USA 115 volt plug for incoming power
and 18 AWG 3-wire grounded receptacle cords for all control relay outputs.
Conduit units are predrilled at the factory and supplied with conduit knockouts for easy hard wiring to supplied
connectors.
NOTE: Liquid tight ttings and some labeled signal leads are provided for all signal (low voltage)
connections, such as water meter, low drum level, ow switch and 4-20mA outputs.
WARNINGS:
1. 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. Wiring must be done
according to all applicable local codes.
2. Power (line voltage) must be disconnected while making any connections. If power is
supplied to the unit, line voltage will be present on the relay cards.
3. Low voltage signal wires (probes, ow switch, water meter, etc.) should never be run
in conduit with high voltage wires.

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 unit should be located convenient to grounded electrical connections,
the required sample line plumbing, and installed on a stable vertical surface.
WARNING:
Avoid 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.

V. System Operation Overview
MicroTron controllers have two modes of operation, RUN and SET-UP. Both the RUN and SET UP menus
are circular. Pressing the DOWN key in either menu will display the next line of information on the display.
After the last item in a menu has been displayed, pressing the DOWN key will return the display to the top
line of that menu.
RUN MODE - This mode is for normal operation. The control relays will only be automatically
active in this mode. In the RUN mode, the display will read system values. If an alarm
is present, the display ashes with the alarm status.
The RUN menu will display values such as day, time, date and other values
depending upon the features present on the unit. The unit will automatically return to
the RUN mode if no keys are pressed for three minutes.
SET UP MODE - This mode is used to make adjustments to settings and readings on the controller. To
access the SET UP mode from the RUN screen, press the SETUP/RUN key. Use the
up or down arrow to scroll through the various SET UP menus. When you want to
access a specic SET UP menu, press the ENTER key. Once you have entered a SET
UP sub-menu you will be able to step through that menu’s options with the down arrow
key.
Relays may be forced on while in the SET UP mode. Press the desired relay test key
to force it on. Press it a second time to turn it off. Once the unit returns to the RUN
mode, relays will activate automatically.
A. Description of SET UP Menu Screens
The SET UP menu is the main menu circle of set up sub-menus used to customize your unit to the particular
parameters needed for your installation. Listed on the following pages is a description and menu map of
each SET UP menu.
NOTES:
1. Your unit may not have all of the SET UP menus listed depending upon your model
number.
2. After you press ENTER or CLEAR to change a numerical value in the SET UP menu, use
the number keys to dene the new value. Press ENTER again to enter the new value.
3. When entering new numeric values, all available digits (characters) must be entered.
The number of available digits depends upon the scale of operation. Position of cursor
indicates number of digits to be entered.
For example, when entering a run time value for a timer in the minute and seconds scale
(10:30 would equal 10 minutes and thirty seconds). You would need to key in a number of
00.30 to make it 0 (zero) minutes and 30 seconds.

contacts from a contacting head water meter
and includes an accumulator for counting the
number of pulse (contacts) before starting the
timer.
2. PERCENTAGE -A continuously repeating
timer where the cycle timer can be programmed
along with the percentage of ON time for the
cycle.

2. BIOCIDE SET
Units with a biocide timer will have this SET UP menu
for setting biocide feed times. The Biocide Set Menu
consists of two weekdays, week and start times and
one feed length time and lockout setting for each
biocide.
BIO _ _ (A1,A2,B1,B2...) WEEKDAY - Select
from Sunday through Saturday, TuesThrSat,
MonWedFri, Every Other Day, Every Day or No
Day. A setting of No Day disables timer.
BIO__(A1,A2,B1,B2 ...) WEEK - Select week
(1-4), Even Weeks, Odd Weeks, or Every Week.
A setting of No Week disables timer.
BIO__(A1,A2,B1,B2 ...) MONTH - Select month
(1-12), Even Month, Odd Month, or Every Month.
A setting of No Month disables timer.
BIO_(A,B,C...)TIME HH.MM - Start time based
on 24 hour clock, in hours and minutes.
BIO_(A,B,C...) LENGTH H.MM - Feed time in
hours and minutes can be set up to 9 hours and
59 minutes, 0 (zero) disables both start times for
that biocide.
BIO_(A,B,C...) LOCKOUT H.MM - The lockout
timer is a timer that starts after a biocide feed time
is nished. The timer can be set for a time up to 9
hours and 59 minutes to lock out the bleed.
NOTE:
On units with option Z-9 this lockout timer
prevents Chem A selectable timer from
activating. On all other units the lockout
timer operates a normally closed pigtail
output.
