4.3 Controller Programming
Press the Mode button to advance to the setting to be changed indicated by the function’s LED. To
enter programming mode press and hold the Mode [m] button for five seconds. The function’s LED
will begin to flash when the programming mode has been activated. Use the [Up]/[Down] buttons to
modify the programmable parameters.
During programming normal controller operation is suspended. If no keys are
pressed for 30 seconds the controller will exit programming mode and return to
normal operation.
4.3.1 Control Modes
Listed below are the different control modes of the MicroTrac controller. Each control mode uses
simple parameters for user modifications.
• Limit Timer - This control mode causes the Bleed and Feed output to energize when the
conductivity exceeds the Conductivity setpoint. The Bleed and Feed limit timers
can be activated to prevent over-feeding of chemicals.
LED Range Function
BLEED 0-08:00
hh:mm
Optional limit timer. Set this value to the maximum amount of time a Bleed
cycle should take before going into an alarm condition. Leaving this timer set
to 0 disables this function. The time value is adjusted in 15 minute
increments.
uS 1-9,999 This shows the current conductivity value.
Set Point 1-9,999 Conductivity Setpoint. Set this value to the maximum conductivity value
before the Bleed output energizes.
Feed 0-8:00
hh:mm
Optional limit timer. Set this value to the maximum amount of time the Feed
output should energize before going into an alarm condition. Once this timer
expires the Feed output will de-energize. The time value is adjusted in 15
minute increments.
• Water Meter – This control mode causes the Feed output to energize when a programmed
number of pulses are detected on the water meter input terminal.
LED Range Function
BLEED 0-08:00
hh:mm
Optional limit timer. Set this value to the maximum amount of time a Bleed
cycle should take before going into an alarm condition. Leaving this timer set
to 0 disables this function. The time value is adjusted in 15 minute
increments.
uS 1-9,999 This shows the current conductivity value.
Set Point 1-9,999 Conductivity Setpoint. Set this value to the maximum conductivity value
before the Bleed output energizes.
