MTD75 Operation Guide
Introduction
Bleed Output User defined Bleed duration, triggered from one of
the user selectable sources:
Water Volume (From water Meter Input)
Timed (Per week/day/hour)
Conductivity (when > set level)
External Input (Contact Closure)
On/Off output at 250VAC* fused to 2A (accessible
on the front panel).
The Bleed output can be initiated manually
through the menu system to permit testing of the
Bleed system.
Inhibitor Output
User defined Inhibitor dose duration, triggered
from one of the user selectable sources:
Water Input (From water Meter Input)
Timed (Per week/day/hour)
Bleed (After accumulated Bleed Time)
Division of the Water Meter Input (X input pulses
give one output pulse)
Multiply by the Water Meter Input (One input
pulse gives X output pulses)
External Input (Contact Closure)
User selectable On/Off or Pulsed output.
Contact closure and 250VAC* supply terminals
provided (fused to 2A, accessible on the front
panel).
The Inhibitor output can be initiated manually
through the menu system to permit testing and
priming of the system.
pH Control User defined pH Control dose duration, triggered
from one of the user selectable sources:
Water Volume (From Water Meter Input)
Timed (Per week/day/hour)
pH (user selectable < or > level)
Division of the Water Meter Input (X input pulses
give one output pulse)
