General Information
20 MTP4000-6000DZV/DZD Operating Manual 31609 A
Fill Uses the selected mode to increase the level or pressure.
Maintain Out Uses the transducer to maintain the level or pressure at or below the target.
Maintain In Uses the transducer to maintain the level or pressure at or above the target.
Note: When the switch inputs are the source of the start event in Xducer & Sw mode, only the switches will stop the
engine.
Maintain Functions
The Maintain In and Maintain Out functions adjust the engine speed to keep the transducer level at the Target Set
Point. The Servo Gain adjusts how aggressively the throttle is adjusted while the Servo Delay controls how often
the throttle is adjusted.
Note: Maintain functions are only available in the Transducer or Xducer & Sw modes.
The direction of the throttle adjustment is dependent on the selected mode as shown in the table.
Dead Band
In some situations, the transducer level may fluctuate around
the Target Set Point. To limit throttle hunting using the maintain
functions, a dead band can be programmed. This value pre-
vents throttle adjustment while the level is within the band (refer
to diagram). In essence, the speed is considered to be at the
target whenever it is within the dead band.
Note: The dead band entered is the amount above and below
the target point. For example, if the target is 5.0 ft (1.52 m) with
a 0.1 ft (.03 m) dead band, the dead band is 4.9 to 5.1 ft (1.49
to 1.55 m).
CANPLUS DISPLAY
Soft buttons simplify the user interface by displaying a button bar above the buttons when any of the first four buttons
(buttons 1 to 4), starting from the left) are pressed. Icons on the button bar change to represent the current function
