TSC VERNIER THROTTLE
TSC Vernier is the most popular throttle selection when operating in the manual start mode. The
operator can control the engine speed anywhere between the programmed speed range. This throttle
type allows you to set the minimum engine speed, maximum engine speed, ramp rate, curve type and
bump speed increments without the use of a computer. At engine start, the display will request the
minimum engine speed. When the operator presses the Rabbit button, the engine speed will ramp up
at the programmed rate until the Rabbit button is released. The display will indicate an up arrow to
the right of the RPM. If the maximum speed is reached, the up arrow on the display will be replaced
by an X indicating the maximum speed has been reached. This same operation applies to slowing the
engine speed down using the down arrow button. A single press of the Rabbit or Turtle button will
cause the RPM of the engine to change in that direction by the bump increment, typically set to 20
RPM.
In the example below, the engine would start at 800 RPM and could be operated up to 2400 RPM.
Pressing a throttle button momentarily would change the RPM by increments of 20 RPM. Holding a
throttle button down would change it by 100 RPM/Second.
TSC BUMP SPEED
The operator can control the engine speed anywhere between the programmed speed range.
However, changes in speed are limited to single presses of the Rabbit and Turtle buttons. Each press
will change the requested RPM by the programmed Bump speed.
