TSC HIGH-LOW MOMENTARY THROTTLE
This throttle option can be used if only two speeds are desired, a low idle and a high operating speed.
The engine starts at the programmed minimum speed and only accelerates when the Rabbit key is
pressed and held. Once the Rabbit key is released, the speed automatically drops back to the low idle
speed. With this option, it is fairly typical to assign a digital input to the Throttle Up function to allow a
remote switch to be installed elsewhere on the equipment.
FLEX-ANALOG THROTTLE
If an analog signal is available from a PLC output or other device, it can be used to control the engine
speed. A Flex Analog channel must be configured to accept the 4-20mA or 0-5 VDC signal and the
throttle type assigned to Flex-Analog. A linear relationship will be created between the minimum and
maximum programmed speeds and the range of the analog signal.
MODBUS THROTTLE
Engine speed can be requested through the modules RS485 MODBUS interface. Contact Controls, Inc.
for a complete register map. The example for speed control is below. Use of 40004 or 40051 is
acceptable.
